I have a question. why is the quad 4 cam tower cover positioned with the words right side up on most of the quad 4 conversions. The quad 4 in our olds calais 442 is has the intake below the lettering and the exhaust above the lettering. I keep seeing quad 4's in the back of fieros and the exhaust is below the letters and the intake is above the letters, but the quad 4 cover is still positioned with the words right side up. Can you just disconnect the ignition module and the spark plug boots from the underside and flip the cover around or am i missing something? Its really confusing because my brain is saying something is different. In our olds, the timing chain and cover is on the left side of the engine, and its closest to the 'H' in high output. If you were to turn the engine around like bryson is doing, then the timing chain/cover would be on left like it is, and the cover leters should be upside down, but they are not. Just a little help??? thanks sean
You can remote mount the IDI and then flip the cover around. To do this you then need to bolt the cover down using the actual cam tower bolts thus messing with the torque sequence. I'm leaving mine in the original (upside down) position.

I'm about finished with it; that picture was taken the other day. I need to plug in all the connectors and see about some things (fuel pump circuit, VSS, A/C), but hopefully I can get this thing fired up soon! --Bryson
awsome job man. it is nice to see a 4 cyl gettin worked on (even though im building my V6) the pics are awsome. keep up the awsome job. can wait to see it finished!!!!!!!!
Thanks! I got to shift my transmission for the first time in a year last night! It was incredible...I can't wait to finish the car to drive it. I finished all of the wiring except for the A/C wires, which I need to do some more research on to make them work with the TEC3. I am running a small drycell battery at the front of the car, and I just bought the wires for it. I should have all of the wiring finished tonight. I've still got to get a slave, get some spark plug wires, make a collector (and the rest of my exhaust), and put the rear brakes and wheels back on. Fortunatley, I found out the other night that I can weld!! I had tacked things before, but never run a bead. I welded up some of the boost tubes and exhaust for my friend's RX7, and they looked good enough to be shown!! I don't know much else about it, which makes it tough if I want to do anything other than mild steel to mild steel. Anyway, I see the light at the end of the tunnel! Hopefully I can start it up soon, but I dont have Mondays or Wednesdays open because of classes until 9:30pm and I'm going to be out of town next weekend. Hopefully I'll update tonight with what I got done! --Bryson

I think I've got all of the wiring finished except running the positives and the grounds, so as soon as I finish the exhaust I can fire it up!! Can't wait until tomorrow; I'll be another step closer! --Bryson

Took me about 40 hours to wire the harness, and I still have to re work it alittle. I noticed the coil packs are 87-88 duke style, Guess you want reliability instead of the stock style.

The coils are actually Electromotive units that I mounted there. I could have run the stock coils and bypassed the ignition module, but what's the fun in that? I love the way it looks without the IDI cover on, which is actually the main reason I am running the Electromotive DFUs. Now that the wires are finished (about a week ago I would have told you 40hrs was overestimating, but now I believe you!), I have to figure out how in the world to straighten things up! With all of the splices from three different harnesses, the wires look like a bundle of snakes! I also started making my collector tonight; I have an idea that will hopefully work! I'll post more progress tomorrow! --Bryson

I'd concur for 40 hours for the first one. It really helped to mock up a firewall on the cradle outside the car to help with the wire routing and length:
Here it is closer to the finshed product:
Bryson, I hope to take mine down the road tomorrow for a test drive.

Bryson, you da man! Take it from a Navy Aircraft Electronics Technician who works on aircraft much older than our Fiero's; rigging a wiring harness from scratch is tedious work. I commend you for your persistance, and you've shown yourself as a role model to all Fiero owners.
Keep it up man!

but now that the engine bay has been rid of that, its sticking out into the center console like some multicolored afro...I need to work on that some tomorrow. I made 3 collectors, none of which worked, so I've got to get some 4" pipe and a hammer and get to work on Tuesday since I won't have time tomorrow. Anyway, anyone have any ideas on where to run a power wire through the front firewall? Thanks, --Bryson

Actually, you don't even need to remote mount the IDI. You just need to unbolt it and turn it around, it works perfect. Almost like they had something in mind...?
No remote mount IDI in that pic, but I've since flipped it back because I didn't like taking out the cam tower bolts all the time and was close to stripping some out.. darn aluminum heads.
Hey everyone, I didn't have a chance to get any pictures but MAN you have to see how it's looking! I have the turbo mounted on the header and my first 2 boost tubes run to the intercoolers and it's so insane looking! I have half my fuel lines run -- the other fittings I needed came in today so I can finish them tomorrow. The coolant and oil drain for the turbo are finished, but I have to run the oil feed, which isn't a big deal. I have to hook up the positive for the car and for the starter, and I need to finish up the clutch before I can drive it. The battery fits perfectly in a little corner of the trunk (it only weighs about 10lbs) and I don't have to use so much expensive wire. I can't wait to get some pictures for you guys; I've done so much without pictures, but it has all been little things that aren't worth taking pictures of but take up a TON of time. My friend also finished his RX7...beautiful! We need to get it tuned, so it isn't driveable yet, but it can move in and out of the shop. Anyway, I'll keep everyone posted!!! --Bryson

I can't wait to see this thing some day....seems like it'll be a wicked little engine. Maybe a handful, with tuning, reliability, driveability, etc. but definitely sounds fun! Do you plan on taking it to some shows?
Here are some pics and a very detailed laundry list of what I have to do:
*Hook up speed sensor *Run line for clutch slave *Get a flange and make an exhaust *Buy and put on spark plug wires and new plugs *Fill with oil/coolant *Weld on wastegate flange and run vaccuum/boost reference *Set up ECU *Run wire to switch on radiator fan (does anyone know if there's a wire for this near the ECU?) *Bleed brakes *Buy and install side scoops
--That's all I can think of...I'm a little worried about the tuning, but hopefully I can find a wideband O2 sensor and a plug to work with the TEC3, since it has the ability to use one. I'll keep everyone posted with my progress!!

I forgot to mention that I'm going to have to cut out a little of the dogbone mount to run some pipe for my filter and I need to make some sort of strap to keep the battery in place. Also, we've got a wideband sensor so hopefully we can get this thing going and give you guys a few numbers. --Bryson

Under your dash look for a green wire with a white stripe. All you need to do is run a wire off of that into a switch and from the switch to ground. Mount the switch in your ash tray and your set.

I REALLY hope you engine is mounted damn solid. It seems as thogh any movement is going to either rub that hose on the trunk wall, Or put your boost tube thru the back window. With all the other stuff you've already done, I'm sure this is all take care of and accounted for, just quick 30 second observations. Is anything else holdng the turbo, or is it just on that manifold??
Good work! Keep it up!

Doesn't look like a normal decklid will work on your car anymore, What are you planning? Im really suprised you opted to mount the Turbo on top of the manifold as opposed to hanging off the bottom of it, I think you will need to do something to the decklid to keep it from burning up. The plastic and the paint will not hold up to those kind of temperatures that the turbo runs at. We are talking about close to glowing red. Also the trunk's seal will burn. That is a nice size turbo though!
I think it looks good. I would have done thing differently but hey thats just me. I will make some suggestions and feel free to comment if you want.
Yes the turbo is mounted fairly high. I would have tried to put it down a bit lower so its not so close to the decklid. Of course you can always change this later. Hell you fabbed it all up that way in the first place so I know it can be moved if you find out it doesn't work well in that location
I also would have mounted the BOV closer to the TB. Should be a bit better response by having it there. I could be wrong but most of he BOV's I see mounted are fairly close to the TB for a quicker response time when that TB closes shut. Also I have never seen one mounted before the intercooler. Your design will still work. But it seems to me that when the TB closes the air that the turbo has pushed all the way to the TB will have to come all the way back through both intercoolers in order to reach and escape out the BOV. Correct?? THats just the way I would have done it is all.
Also looking at the turbo to intercooler routing, the feed pipe from the turbo to the intercooler is above the glass line where the decklid would sit. You are either going to have to modify your decklid or reroute the feed pipe to route underneath the other intake pipe that runs from the passenger intercooler to the drivers intercooler. I hope that made sense and you are able to understand what I am talking about. Or you have already test fit your decklid and it all fits but by looking at one of the pics it doesnt' look like it will. But maybe its just he angle
Either way I love it!. It will sure be a beast once you get it all tuned. Glad to see someone going to this extreme. Its gonna make some good power and I am sure once its all broken in and tuned, you will have no time spanking plenty of fast cars. Get to a strip so we can add your car to the E.T. qtr mile times thread.

Wow... looks great Bryson. I am gonna have to come by the shop to see it up close and personal. I bought an 86 GT with the SC3800II conversion since the last time we spoke. I am still driving the SE as a daily driver...

Practically no difference, you are only loosing a cast iron head but putting in a heavier crank, exhaust manifold and an extra cam. So, you might put on a couple of pounds, but most likley less then 30.

what size is that turbo? is it a P trim? how many mm is the compressor wheel? what type of tranny are you running?
Thanks Prasad

Thanks everyone for the positive response!! The engine bay will passivley vent the heat I imagine; I made a pretty large reverse scoop (just like the mustang scoop) in the decklid to help with engine heat and clearance issues. I am going to run solid engine mounts -- that's one thing I forgot to list and I actually forgot I still had to do! Thanks for the reminder! There is actually a lot more room that it seems, but I still want to mount the engine solid so that I don't take chances. I have some braces made up to hold the turbo to help support some weight. I know that mild steel manifold won't last long, but I'm trying to make it last until I can save up a little extra money and build a stainless one. I was going to run the turbo towards the bottom, but the headers would have been crazy difficult to make, and I think I would have had to take a hammer to the trunk for the turbo. I think my turbo is not in a very good location, so the next headers will either set the turbo down some or run towards the transmission. I am looking for some sort of sleeve to put over my turbine housing to keep the heat off of the decklid and everything else. I will also probably put some insulation on the underside of my decklid to help with that as well. I didn't think about the trunk seal; that's a good point. The seal is messed up anyway, so maybe I can use this one as a guinea pig to try different things to keep my new one from melting. As far as the location of the BOV, it is actuated by a vaccuum reference from the manifold (which you probably know). Since it will open and close at the same time regardless of where it is on the boost line, I decided to put it close to the turbo because it is designed to prevent compressor surge, which is boost backing up to the turbo. I looked at it somewhat opposite from you. From a performance standpoint, it may be better to mount it by the TB so that when you are back on the gas after a shift less area has to be pressurized, but for safety of the turbo (and so I didn't have to weld that flange onto a different pipe ), I like being able to release the air right at the turbo so that there is no chance of the charge air pressurizing the housing. Topcat: wow!! Yeah you're right you gotta come by the shop; I want to see YOUR car! I have yet to see a Fiero with any other engine swap, and the 3800SC is one of my favorites. The turbo is a T3/T04E with a 60trim compressor wheel. I am not positive, but I think that a 60 trim is a 60mm inducer on the compressor side. I can check that today or tomorrow. The turbine wheel is what Garrett calls a "Stage 3" wheel. It is the largest they offer, and since I have a "larger displacement" 4 cyl (haha) they thought that would be best for the amount of power I am looking to make. I think that P and Q trims are Turbonetics options because my friend had to choose between those for his T70 on his RX7. I'm using the stock Getrag 282, but I've got a spare I picked up and I'm going to build when I get some money. I don't drive hard and the car will hardly ever see high boost, so hopefully I'll have some time before I need the other one finished. By the way -- looks like you have some awesome cars youself! I'm going to be setting up an water/alcohol injection system in my friend's RX7 and in my car as well. I was talking to a guy who owns a dyno and does amazing work and he was telling me about someone else with a TEC3 that has it programmed to open 8 other injectors when he flips a switch and it runs alcohol (or nitro methane, I don't remember) and completely different fuel maps all the way down the track, and once he lets off the pedal it immediately switches back over to gasoline to keep the cylinders lubricated! I'm not going to do anything that radical, but I'm glad to know my ECU has that kind of capability. I at least want to have two different setups for economy driving and performance. Anyway, I've got class in about an hour and a paper to write so I'm off for now! Thanks everyone! --Bryson

Some honda guys actually like to weld the bov flange to the outlet of the intercooler. No clue why. I put mine right in front of the throttle body.

Thanks for the reply, I also like the Alcohol injection setup. So far we were able to run 16 psi with a PT70 turbo & 72 lbs injectors on 93 octane with 0 knock retard ,where with alcohol we were able to to push 20 psi with alcohol and 93 octane 0 knock retard with the same setup. Tuning with alky is little different as far as the EGT is concerned, you need to compensate for the alky cooling the exhaust.I think these guys have a real good alky system http://www.smcenterprises.com. I beleive it is worth it for around $400.00. I can wait see your car running hard, it will be a beast. You also have nice clean installation .
Good luck Prasad
