I guess I am the odd ball......... rubber mounted engine and rubber mounted trans. a few years old now and very pleased with it. I did use polly mounts on the cradle.

Hey everyone,
Finally got the Fiero back on the ground after a lot of work.
Today I was able to fire it up and it ran strong. I had to hook up the mechanical pump and put a line in a cup of gas though.
I will probably end up putting in a 4 cylinder fuel pump with a pressure regulator inline.
I was wondering for all of those out there that went with a carbed setup if this is what you did and how it worked out for you?
Thanks,
Jeff

Jeff, I have a Mallory 'by-pass' style regulator on mine using the 4 cylinder fuel pump, I have a pressure guage on the regulater and it seems to keep it pretty steady, you should be able to see it on the drivers side of the engine.

84SE, aero body, 5 speed and a 350 V8

Does the bypass style mean that it has a return line coming out of the regulator ??
Thanks
-Jeff

Jeff, yes that is correct, there is already a fuel return line in the car, so I hooked it up to that, the bypass style should be easier on the fuel pump than the cheaper style that just restricts the passage of fuel, at least I hope so !

Hey everyone, Just figured id post at least this picture.
Getting pretty close to a test drive.
I just have to hook up the lines for the remote waterpump and adjust the clutch fork.

I want to post a video clip of it running. Sounds pretty sweet.
Just in case anyone was thinking about using Moroso Spiral Flow mufflers.
Not sure where to upload it though.
If anyone knows let me know.
Thanks!
-Jeff

I want to hear! If you cant upload it then how about sending me it in an e-mail? I have the same mufflers on mine and havent started it yet.

Yeah please! I need to do that too one of these days.

mafv8,

Do you know the part number of the regulator you used? I was getting ready to order the Holley 12-803 for my swap but It seems like your's with the bypass is doing well so far?

Thanks

The regulator I used was a Mallory part number 650-4309, JEG's has it for $75, I got mine from EBAY, for about $40,
Mike

I am using the same regulator as mafv8 and although I havent been able to run the motor much since the cooling isnt fully hooked up yet, it seems to be working just fine. It is at 5/6 psi. I may adjust it later.

I tried to upload the video of my car running onto putfile but it doesnt seem like it wants to go. Not sure why.
So Jake Dragon check your pms I need you email so I can send that to ya. Anyone else that wants to see just send me a pm if you are interested.

-Jeff

It sounds great, glad it worked so we could hear it. Why are you running cats on a carb setup?
My mail box wont accept anything over 5 megs so I’m glad you got it uploaded.

Thanks Jake.
Im glad I got it uploaded too.

About running the cats, I guess I had never thought about it.
I know a lot a bout cars but there is still a lot I dont know.
Is it that using cats with a carb setup wont really do much to help emissions
or is it that it will do some sort of harm?

-Jeff

I dont think it will hurt anything and when.. I mean if you change to injection you dont have to buy them. Just weld in the bung for the O2 sensors and your done
I have never heard of using cats on a carb setup, dosent mean its wrong.

Plenty of cars made after 1974 used CATs and had carbs. They will reduce emission levels in engines with carbs just as they do with fuel injection. I'm in PA and the visual inspection requires CATS on all cars that originally came with them so you'll do no harm with them.

The other nice thing about the new CATs is that they flow so much better than the old crap we used to use ( my 86 442 - Carbed and 87 Grand National S.F.I. were really bogged down with the converters). It's nice to see the new ones don't really rob that much HP. (Some as little as 2-3HP).

On the other side of the coin. There are plenty of Old Fuel Injected cars that were around years before they even dreamed of using CATs. My Dad's old 63 Corvette did'nt exactly have CATs with it's fuel injection that's for sure..

They used cats with carbs from 1975 until the mid '80's.

I didnt know that. I was going to install some short cats in my car so I didnt have to do it later when I install the fuel injection but ran out of cash when I was installing the mufflers. They dont check for them in Florida.

quote Originally posted by JeffB: OK nevermind. It decided to work this time around on putfile. So here is the link to my stuff: www.putfile.com/fierojeff The video might be on there twice by accident, but there she is. I have the sanderson headers, I was able to fit cats just before the Moroso Spiral Flow mufflers and the tips I will use are the Monza twin resonator style tips. They arent on yet, but I dont think they will change the sound very drastically. The recording isnt too bad, but it still isnt as sweet as hearing it in person -Jeff

Don't know why but it is not working for me

As far as fule pumps go, I ran the stock 6 cylinder pump trhough a fuel regulator for a short time but the regulator was going nuts with the high pressure. I finally simply added an off the shelf aftermarket external electric fuel pump from a local parts house for $40. I have a write-up on this page http://64.17.190.253/fiero%20stuff/Fiero%20HTM%20files/other_stuff.htm I disconnected the stock fuel pump electrical feed and ran an ignition-on only line to the new external fuel pump. I have an external shut off switch on the pump just 'cause I cud. The stock pump is still in the tank. Don't need a bypass line with a carb, just good seats on the needle valves.

It runs strong to about 6400 rpm, highest she has gone so far. Roads are still a bit wet around here to do more. Winds out so damn fast that I am too busy watching the side of the road 'cause it keeps trying to go sideways.

tvelarde- were you running the 6 cyl fuel pump through a bypass or non-bypass style regulator before it had problems?
Alex- do you mean my video isnt working or your trying to upload a video there isnt working ?
I think I had to update my quicktime or whatever that uses for it to work

Just got the water pump all hooked up.

Heres a picture of it out of the car
http://community.webshots.com/photo/480117603/2337270070064377246eXTBBg

Here is a picture of where it is mounted. It is just in front of the rightside wheelwell. It all tucks in there real nice.
http://community.webshots.com/photo/480117603/2596611640064377246MfkYLt

In this picture you can see the bottom mount for the waterpump and the pipe from the gooseneck run down through the same area before it crosses the bottom of the car.
http://community.webshots.com/photo/480117603/2949338050064377246OsIflg

In this picture you can see the two lines running from the block to the waterpump and the hole i cut for the pipe from the gooseneck and the lower pipe for the waterpump.
http://community.webshots.com/photo/480117603/2030829070064377246sUwWjo

This is a little closer up and a better angle. I used an old vacuum line for the gromet around the hole that is cut. I still ahve to put a little more though.

I can see a lot of those nice expensive $$ braided lines and AN connectors

My original fuel setup was using the stock V6 fuel pump, restricting the pressure with a non-bypass regulator. I did this as an expedient measure to get the car running and not wanting to drop a tank full of gas. Didn't take long to burn through the gas and after some tuning and driving I simply took the stock in-tank pump offline by switching the power feed to a new external fuel pump, old school. No problems with maintaining 4-7 psi and the engine has had no fuel starvation problems to date. I have a few high speed runs on a 12 mile "backroad" here on the island and have had no problems fuel-wise. My only problem is watching for deer and lstening to the loud yelling coming out of me as I accelerate out of the corners.

Finally got to test drive the Fiero I had a friend of mine come over to help me tune the carb just right.
The throttle response is awesome, and it pulls real good. I have to baby the car for a bit, break in the clutch 500 miles,
take it easy on the motor cause the guy i got it from said it was a relatively fresh rebuild.
Every so often though, I got on it a bit. Not much at all, just lettin the clutch out kinda fast at like 2000 RPM.
Then this happened :

(this is the drivers side axle, broken right next to the outside joint)
No big deal. I thought I had tightend the nut on the outside of the axle too much, and that is what caused the break.
So I got a new one for free, lifetime warranty on it, put it in and it was good.
I got on it just a tiny bit this morning and same thing. Had to push the car like 5 blocks.
I dont think that its the axle shaft being too weak.
I think its the joint on the outside binding up or getting jammed up
and in turn the axle snaps because it wants to be spinning.
So I figure the angle of the axle is no good, and thats makin it get jammed under a little stress.

I havent adjusted the control arms yet, they have the new poly in them and the weight is a little different now so i know they need adjusting. The question I am wondering is whether or not the camber of the tire could effect the angle of the axle great enough to cause it to break ??
Well I sure hope so, I could really use some advice from you V8 fiero owners out there
Thanks
Jeff

Unless there is a situation present causing excessive stress on the axle in addition to what it's getting from the engine, you may need to find an original axle, there is no telling what you are getting in the remanufactured axle which only parts of may have come from a Fiero.

It must have just been crappy autozone axles becuase the 3rd one I put in has been just fine. Just have to figure out why the fan isnt turning on and why the temp gauge isnt reading. Once I get those two cooling isues squared away I should be able to put some serious miles on the car and break that clutch in.
-Jeff

Jeff, great reading your success and challenges! Maybe you could post some more videos in the near future? I'd love to get a ride, sounds awesome!

All of these swaps require some debug time. Some things could be minor some big. The good thing is every time you will have a better swap After a year I still have some to fix myself.

Cats will cut down on the exhaust drone for sure. I like to run cats but no muffler. Sounds great!

Did you ever remove the spring and cycle the drivers suspension from full droop to full compression while rotating the wheel hub (and axle - installed). If it binds at all you will have axle issues.

I havent attended any sort of Fiero festival yet, but once things are all worked out it would be a blast to drive in a caravan to wherever for a meeting- Id be more than happy to give anyone a ride at one of those things John-
Thanks for the encouragement Alex- one thing I always try to remind myself when working on cars is that I aaalways figure it out- reguardless of time money and headache, things seem to come together more than fall apart- Thanks Joe- I honestly didnt do much more thinking than hmmmm imuna cram a cat and a muffler into my exhaust system... Im glad it turened out well though : ) and I like the paint I used for the exhaust- you cant see the exhaust much but the dull flat black keeps it from sticking out at all- Guru I never did do that, now that you mention it I probably should have done that right off the bat, but I was counting on the lifetime warranty, the ease of instillation/removal (aside from popping the inside metal boot part out of the trans) and luck- eek but it seemed to work out just fine. Il take some more pictures- I know i shouldnt be droppin clutches but i had to do it just a little bit in my driveway to see if it broke, and it spun the tires, left some lines in my driveway : )
Il get some footage of drivebys and behind the car accelerating away and all that good stuff-
Seeya guys!
-Jeff

So, how is it running now?

After listening to the Moroso spirals I may decide to go with them.

A (+) for you.

John
