First off i want to say this isnt inteded to start any "what motor to do" flame war, or step on anyone who sells harness's or parts for the swap. In fact some of those people i will need for my swap.

This is going to be a step by step dummies guide to a series II install!! With tons of pictures too!! Since i have never done this swap and am pretty NEW to it your all going to learn WITH me... so in the end it should turn out to be basically a how to install thread!!
I will size down all my photos to be nice BUT if anyone wants a larger version i can email you one!

Here goes...

The engine is from a 1996 Buick Riviera, this is the only thing i dont have any pics of!! (ok its not a TOTALY documented swap, i dropped the ball on the deinstall from the Riv)
It came out pretty easy through the TOP... wich is how the guy helping us at the yard wanted it. Just pull all the tranny mounts, totally pull the passenger side engine mount from the frame. UNPLUG your harness from the firewall, then trace the cars side of the harness back to where it enters the firewall and cut it there... You will be left with a 2 foot section of the cars side of the wiring harness... This will be usefull because you can splice all this to the fiero and still unplug the engine for various reasons. I made a WOOPSIE when i cut 2 relays off this harness... DONT do that, i think one may have been the fuel pump relay. DOH! Get everything you can!!!

Here come the pictures... To start here is a good shot of a 96 Riv that frightningly looks IDENTICAL to the one my engine came from, Damage and everything!!

Once you rip out your engine it should look like the following!

Here is a no cover shot.... im debating still moddifying the cover so i can use it... Good for a SLIGHT attempt at sleeper vehical, or a more stock appearence, however when i go to show it off, id like to remove the cover so she looks like this. (technical note, if you dont have the shiney grey thing on the top there you got screwed!!)

Here is a cool shot of the engine and her future home!

Ok, ok, now for the fun... I pulled the charger because A; I wanted to polish the outside and make it look WICKED umongst the rest of the engine wich i want to paint black.... However, powder coat on this thing is THICK and i mean thicker then George Bush's head!!! SO i was gonna wire wheel it off with a dremel (nice for hard to reach stuff) now that i have a few baron of paint spots im stuck going for it, so i may try sand blasting OR chemical stripping, any suggestions are much loved! And for reason B; I found some porting instructions online to make it a little more efficient... so ill give that a shot too!!!

Here are a few pics of the series II blower as it sits on my counter!

^^ Above you can see the stock outlet where i am going to port her out some to make her look a little bit more like the ZZP outlet show here...

I have also heard about porting the throttle body AND blocking the EGR inlet both of wich i will research and post more on here soon.

aperantly dotphoto doesn't allow hyperlinking - try www.photobucket.com

They did work but i must have over went a bandwith or somthing? CRAP... I fix ASAP! Thanks for the link.

All moved to PFF hosting... now is all good!

TODAYS update!

James (Fieromaster88) has been telling me to just get the engine in and running RIGHT before i toy around with it too much SOOOOO i decieded to do this. Im putting the blower back on and I am going to start moving wiring to conceal it a bit more. I am not a fan of the clustered engine compartment.

KC (Low_Key) has told me that he test fit a Series II computer and it FIT under the center consol so im going to wire it that way.... My other option was too the trunk. This would benifit as its stock wire routing and also you could adapt the rear cooling fan to cool the ECU! Stan (StansGT) has his by the battery, however i want my battery in the stock location for now unless i have someone tell me some excellent benifit from moving it!!!

I also am going to post any part numbers for parts i use so that you can try the same parts. So soon as my G/F gets back with SC gaskets ill add them to start a list.

Here is a list of things to do at this moment....

1- Remount the blower
2- Plug everything back together and decied for sure wich way to run the wiring (trunk or cabin)
~~~~~ A= If in the trunk i can make a box for it and custom fab the cooling fan in rear to blow into box to keep ECU cool
~~~~~ B= Running it into the cabin keeps the stock look and cleans up engine wire mess, but may have to extend some wires.
3- Wire the ECU to the extra harness section robbed from the body side of the car! - NEED to find out if i cut off any NEEDED relays when i hacked the 2 off!
4- Get info on custom burned ECU chip to get rid of Tranny, Emmisions, EGR, and other codes i may get.

once i test mount the motor to the cradle i have a few other things to do BUT i am thinking about them now anyway to get a jump on them... they are...

1- Replace water pump (its got 80K preventitive maintenance)
2- Forgot to grab the starter, or it was gone, DOH need to get one
3- Oil filter location, may need filter extension from another car
4- Clutch... what to use with Isuzu to last till winter when i go get a Getrag
5- Coil pack location, why not stock spot? Make box for them and cool with rear fan?
6- Flywheel info... needs machined and balanced but need to research that. (good thing i grabbed the flexplate to match the balance needed)

For now thats it... My g/f's dad has a mill and lathe so this winter i am going to experiment with making some parts... fuel rails and such... if you have any suggestions let me know. The Grand Prix guys talk about a wipple supercharger but want like 2k for the mounts and stuff... i should look at making those too!

This thread is just what I need. I've been planning on starting this swap in a few months. LOTS of pictures ! haha

dude lose the cover or I'll eat it when I see your car! it'll be a sleeper no matter what it's a fiero

check the clubgp.com classifieds.. you can probably get a dub system like I was telling you about for pretty cheap

3800 SC/IC Fiero fixed and weeeeeen'in again!

Fieromaster.....
Could you also post prices of any additional hardware and if needed, and special parts/part stores that you had to use?
This would help come up with a total cost. I realize engine costs will vary.
But the additional hardware should at least be close.

Thanks

First off i did a BIG edit above to my post before this one... check it out if you havent.

NorthFloridaFiero - Glad i can help... i will have TONS of pics... i have 2 64meg cards and if you need any BIGGER versions i can mail you them!

JKFiero - Will do that along with my part number list. I will also include instructions on HOW to modify stock parts so they work. Anything that i have to make that others may not be able to i would possibly sell, as long as i have the time to produce products with quality and quickly. (work eats up allot of time)

This Style Blower is only in the 1996. The Black Line on right side is blocked on the 97-04 engine.
It is the only Year they painted the hole blower. It is a M90.

So what didnt they paint in the other years?? Are you talking about the black vacuum line stack on the right??

this thread looks like itll turn out very helpfull to anyone interested in do ining this swap but me i am to lazy to read all of this so i ll just make the guy that wrote this help me if i ever get un broke enough to do it to mine lol seriously loooks good craig

For your first list, add to it- figure out your belt routing setup. The pulley thats under your coils will interfere with your decklid. Loyd over at www.fastfieros.com or darthfiero www.gmtuners.com are both excellent sources for getting your ECU reprommed. From what I've heard, you should keep EGR on your car. It helps it run cooler and as such, reduce KR.

As far as your questions go...

1- Replace water pump (its got 80K preventitive maintenance)
Doing some other seals like valve covers couldn't hurt either.

2- Forgot to grab the starter, or it was gone, DOH need to get one
You use the starter off of a v-6 fiero..

3- Oil filter location, may need filter extension from another car
Yup, that filter will interfere with the front motor mount. Try getting one out of a grand prix

4- Clutch... what to use with Isuzu to last till winter when i go get a Getrag
I'm pretty sure the isuzu and getrag use the same clutch and pressure plate, just the T/O bearing is different, can someone confirm this? You should contact SPEC, they will be able to tell you (www.specclutch.com)

5- Coil pack location, why not stock spot? Make box for them and cool with rear fan?
Again, same with that pulley, will interfere with the decklid. You can get away with moving the battery further towards the side, (relocating it upfront is better) and put the coil pack where the battery was.

6- Flywheel info... needs machined and balanced but need to research that. (good thing i grabbed the flexplate to match the balance needed)
Get it out of a '96 V-6 Camaro. Machine it down to 0.840" from the mounting surface on one side, to the friction (where ther disc applies to) on the other side.

I think your two biggest headaches (as are mine) are the wiring as well as the pulley situation. I'll try to get more pics up of mine on how I resolved these.

Cool thread, really helpfull.

As for the clutch...yes all Fiero Trannies use the same clutch. Just the T.O. bearing are unique to the particular transmission. But get the best clutch you can, I recommend the spec too.

Also, you can get the flywheel from an autozone for like $50 with a $50 core. Machining is usually around $70.

Thanks for the help RandomTask... ++++ !!! I'll have to check into the pulley thing. I may go that route with the coil packs too... ill do some poking around to see what i can figure out. Would mount them to the engine side of the trunk wall but that would need wiring harness lenghtening im sure! I will check autozone for the flywheel too...

Incase you need some references to things we stumbled on check here. https://www.fiero.nl/forum/Forum1/HTML/049118.html I used the same car and if you are not going to use the trans I may want to buy it if the price is right. 4t60E hd is my axle set up and I want a extra incase I tear this one up doing wheelies.

Great thread, and awsome job of documenting everything. A + to you!

Fieromaster:
Here is some info on the adapter for your oil filter that you might find handy:

96-2002 L36 Camaro
GM PART # 12569217
CATEGORY: Engine Oil Filter Adapter Hardware
GM LIST: $31.90
OUR PRICE:$19.10

( I have pictures of this installed if you like, E-mail me and I can get those out for ya if you like )

or:

( I belive that this is the one that WCF sells. They are going to do the same thing for ya, so IMO, I'd go w/ the one that is listed above.

91-95 Lumina, 92-95 Transport, 92 Bonneville, 91-92 Olds 98, 91 Toronado, 92-95 Silhouette
GM PART # 24501300

OUR PRICE: $75.79

Also, all prices were from GM Parts Direct.

Also, you are going to have to replace the bracket that you have there with the one that is installed on the GTP. ( Firewall issues will abound with that one installed.)
Check this part number here, as I had to do the same as you.

GTP Bracket Part #: 245o7211
GMPD had it for ~45.oo when I bought one ~ a year ago.

Reasoning enough to move it

GL, and great thread!

------------------

MCaanda... AWESOME info.... ill add all those part numbers to my post above... ++++ 4 you

The participation in this thread is AMAZING and much, much, appreciated!

I will post the pics (allot of em) of the stuff i got done today some time tomorrow...

I put the blower back and took some pics of the gaskets and how much porting could be done, also swapped the valve covers over as the oil fill would be on the cabin side rather then trunk side.

Your in the Cleveland area too eh? Is your swap complete now? I dont know Ed Morad, so if you could enlighten me on his products id be much oblidged!! Might have to come out and check out your swap??

quote Originally posted by RandomTask: From what I've heard, you should keep EGR on your car. It helps it run cooler and as such, reduce KR.

Why have you heard that... just wondering because the EGR would totally heat up the blower and components by allowing hot gas into the system... I would figure that would RAISE KR because hot air helps cause pre-detonation. Wich is why people get intercoolers.... Just curious, because what youve been told makes me wonder...

[This message has been edited by The Fieromaster (edited 07-16-2005).]

Ok here is some more work...

Yestarday i put my charger back on, all fresh gaskets... the part numbers are in the on-going list above!!
Anyway i started by scraping all the gasket material off the parts... if for some reason your new to this, it's very important to do.
Well upon cleaning my parts i discovered the Gremlins that would surley have caused me trouble... They were hiding in the motor that i was going to put in my car... Think of that... waiting, sabotage!!
Well i got them i did i did!

Discovered their nest...

Infiltrating their hive....

Even more hide deeper!!!!

Yes... they were all dead, but just to think those little buggers found a place like that to hide in the first place!

Ok so now that i got rid of the evil little gremlins and installed the chager I decided to change the valve covers around. I dont like the idea of having to fill the oil on the back side of the engine!! So here are the steps.

Here is the coil pack it needs to come off... A- because its in the way of the valve cover comming off, B- I am going to mount it where the battery goes... Mcaanda's car makes me drool... reason enough for me!

The pack has 3 bolts holding it on, they are below in the pic as best as possible. Bolt - A - is under the blower snout and easy to get to. I put bolt - A - back in because from what i could see its an open hole to the inside of the block, or coolant passages... NOT good for me. Id suggest you leave it there too... Bolt - B - is to the left of the tensioner... it goes THROUGH the bracket and holds the tensioner on too... It HAS to stay! So put it back. Bolt - C - basically does nothing but hold itself in when your done... so far i see no reason for keeping it, but i will because i am uncertain as of now! Although if i get the GTP pulley for there as suggested by Mcaanda then i wont need it anyway.

That cover is now ready to come off... All you have to do is LOOSEN the bolts... dont pull them out. They have nifty gasket/plug/holder in er things... Basically they wont fall out because clips "lock" them gently in place.
Pull the cover up and rock the top toward the charger and it will clear the engine lift bracket perfect!

For the other side, there is a engine lift bracket of ENOURMOUSNESS. It also has the wire for the O2 sensor on it. Chuck that ugly bracket by pulling the 2 bolts off it. They threaded on a stud end of the exhaust manifold bolts. Get rid of the giant hunk o metal!

Now you have to pull the bracket that has the Map sensor egr heat sheild and another vacuum valve on it... unsure of what its for. I dont remember but will when everythings back together. There are 2 bolts in the charger for it (they DONT hold the charger down also so dont worry about pulling em out) and one bolt on a stud near the Throttle body... the bolt only holds the brackets and egr sheild down BUT the stud under it DOES hold the charger down... dont take that out!
The pics for this are below... i already have the bolts out so just look at the shiney parts of the brackets and youll see where they go.
The mess o bracket...

AT MY 8 PIC POST LIMIT.... Will continue with this valve cover removal below... probably typing it as your reading this... so dont ask nothin bout this part till i post the rest LOL!!!

This is a 98gtp bracket:

But it is a very heavy cast iron piece and I hope to find a belt setup that doesnt need it...Appearantly there are some more minor differences between years and types... keep up the write-up !

Craig:
As for the oil filter adapter, there is no need to remove the tire, or anything for that matter. Once installed into the car, there is almost enough room down there to throw a party for 3 or 4 of your closest 38oo SC’d Fiero friends.

Also, in your E-mail you were asking about the belt routing. I went w/ a custom lower alternator mount, as you may or may not know, there is going to be a 2ooo WS6 Power steering rack installed into the SSEiGT, and I needed the room up top. This part of the install will vary greatly with each install, dependent on what you are going to be doing and where you are going with the modifications of your car.

Check out that Oil Filter Adapter as well - this is the best shot of it that I currently have.

Here is a picture of my routing, and there is a great picture of the Camaro adapter that I have installed. Also, I forgot to tell ya that you are going to want to check out GMPD ( GM Parts Direct )

Here’s the Catch: GMPD charges outrageous prices for their shipping, so they make up for it on the cost of the items. You might want to see about contacting your local dealer to see if there is that big of a difference, and go that route. My adapter went B/O for 1½ weeks and they didn’t inform me about it which I thought that they should have. The kicker is, that when I did finally get it, it was shipped in a Virginia Slims Light Menthol 12o Box ( same thing that my mother used to smoke )
Check into it and see what you can come up with.

Also, here is a good picture of the GTP bracket that you are going to need to get. I just found this picture, or I’d have gotten it for ya in my last post. It also shows the belt routing and the oil filter adapter off of the Camaro that we were discussing earlier.

If you are going to mount the ICM and coils on the side of the firewall, you WILL HAVE TO ensure that there is a good ground between the ICM and the frame / motor. This can be taken care of with a good sized grounding strap that you can procure from the local NAPA store and attach it to the mounting plate that the ICM and coils sit on. If you havent heard it yet, grounding points are your friend, and the more ( within reason ) is allways better.

Fiero master,

Do you have Collector plates on your Fiero? If you do, alot of the vacuum lines that control emissions can be removed. The map sensor can be relocated over were the boost control is. The map sensor holds the valve closed. The boost control is removed - http://fastfieros.com/tech/boost_solenoid_bypass_mod.htm If you remove the boost control, add a small breather, by drilling a hole in the oil cap and inserting the breather there.
The vacuum that works the brake booster is also relocated to the side of the blower and a plate fabricated to cover the hole, that is left on top of the blower.

BTW, I send you a P.M.

Talked to WCF, was ordering some header flanges. He asked me if I wanted EGR on them to which I thought of the difference of "want" and "need." So I asked him if it would be bad for me just to block off the EGR entirely. He then told me about all that (running cooler) of it producing KR...

Thanks again for all the info... so that youve seen you have no integrety problems with the blowers with that done? I just dont want to over heat it by all the extra work... BUT i do want that sweet sound!! Is it more noticeable with that mod done to it (the sound)?
As for the breather your talking about... what is this for? I have a breather canister, wich i was going to use for PCV valve but i dont see one ON the valve covers like the Fiero or most other GM's

DO you have any other pics of moving the MAS sensor and valves besides whats on the site for removing boost control??

Thanks again!

Rborecky,
We will deffinetly have to get into contact... i, a VERY long time ago, went to a Cleveland Fiero meeting, however the group seemed to be mostly older crowed (not that its bad, but a little on the serious side to me) maybe i mistook the attitude, wich could be my fault. This was some time around... oh man... maybe 1998-1999. As for where i live... its about 40 minutes east of Cleveland off RT 90. I will have to shoot you an email some time tomorrow... I am beat right now... need sleep!

Take care!

Mcaanda.... I cant thank you enough either... Im SO glad there is so much help in this thread. I just am hoping to help clear the mysteries there are with this swap. So that more people can enjoy the gains of a great engine! I sent you an Email but ill have to remember to ask you a few things about routing belts... As for the alternator, i MAY stay with it up top, HOWEVER... I like the way its mounted in your pics above... how is that mounted?? Looks SOME custom but kinda stock too.

Lastly... what happened to the lines comming from the water pump area for the heater core... the steel ones that press in and are held in place with the bolts... I dont see them on anyones swap...

AGAIN THANKS EVERYONE!!!!!!!!!

You know, you could have a a 4.9.

I'll visit and help you get that thing in the car so this wont be another 2 year project. Looks good so far. Need to do a lot of painting/polishing.

I drive way too fast to worry about cholesterol.
"Whatever happened to stimpy?"

Painting and polishing comes after i know everything runs good...

I just dont want to take the blower apart to sand blast and polish it unless im going to put new bearings in it. That will take more time and more money. Ill give it a heathy bath though before i put it in with some de-greaser. Heck im still deciding what color to paint it?? There is a powerder coating company near here that can powder coat ANY color... i think even METALLIC!!! Maybe ill go SUPER dark puprle to match the car, and then polish the blower... then either the same dark color on the pullies or somthing contrasting? Who knows...

If you look in the photo, you will see the fuel rail and the breather that is in the oil cap. Remember, we removed the boost control and the valve closed for good. That breather is there, for when you let off the throttle, the engine will not be fill with boost and pop a gasket or worst. As for the PVC valve, it is in the blower under the black plate that has stamp on it PVC.

Notice 1 & 2.

3 is what you'll need for your passengers

In this one I've circled where it plugs into the block. I've also circled on of the bolts, the other should be behind where the alternator is. You take this bolts out and pull the assembly straight off. The plugs that stick into it are made of aluminum. Make sure you try to pull it off straight as possible as the aluminum is brittle and can crack easily. When I did mine I managed to break both plugs on it and had to dig them out (not difficult at all to do) you then take 1 inch steel freeze plugs that can bought at any advanced or autozone. (try to get the deep style as they will seat easier)

Classic, simply classic...

The 3800SC is my wet-dream swap. Thanks for taking the time to document all of this.
I've learned almost as much in the past 1/2 hour as I have the entire time I've been researching this swap. I'll be following this closely.

How does the heater core get it's coolant flow?
Just as important, doesn't something need to serve as a bypass until the thermostat opens? I remember reading some other posts that speculated that blocking these off was what was causing the mysterious "crushed thermostat" problem in other installs.
I know there's the largest possibility that I'm jumping the gun here, but no time like the present to ask.

Read Nealz Nuze!

From what it looks like in the pics above (3.8 SC's engine) i think they are using the thermostat housing that they modded to fit the fiero to feel the heater core, as there are tubes comming out of it that WOULD have gone to the throttle body in the 2.8 boat anchor, but now feed the heater core... Am i correct in my assumption?? Why NOT use the stock ones?? Is it a space issue and its in the way of something?

By removing that assembly it frees up holes to bolt your alternator and dog bone mount into. If you wanted, you could thread/attach an adapter and route a hose out of there. Either way however, you have to run a custom thermostat housing. The Fiero's front radiator setup will make it impossible to bleed the air out of the system if you use the stock 3800 housing.

You would be correct! We modified a Fiero V-6 housing and that feeds one side of the heater core. If you look above the oil filter, you will see the modication that was made to attach the other side of the heater core. BTW, on 88 and I think 87 Fieros, the heater core attachment is in the passenger side radiator tube. So some people just block the whole right of the engine off, for the heater core. Even though my Fiero is an 85, I am using the 88 Fiero's heater core, connection.
