Are you going to use VW wheels ?

if you think that your fab work on the vr6 will allow you to get a 20v or tdi motor in lemme know i wouldnt mind keeping your info on file for a next year project. not to sure where my soon to be wife will get stationed after she graduates(army) but chances are decent we'll stay in virginia. i kinda wanna just piss the vw dorks off at waterfest and bugout and a tdi fiero would be the ultimate bastard child.

on the vr6, with it in a fiero are the crack pipes and serp belts still a joy to work with or is it all around much easier to work on?

o and remember the 3.6 is called a v6 now, sure it looks like a vr6, sounds like one, and has only one cylinder head but hey, who are we to question wolfsberg

No, the VW rims were sold to help pay for the mods to this drivetrain. They do fit, though. I have the Fiero GT rims on the Jetta right now and it doesn't look that bad.
The 1.8t & 1.9TDI looks like it would be an easier swap, and is definitely on the back of my mind now that I know what needs to be done to get it in the car and functional. The crackpipe (solid cooling pipe under intake for you non-V-Dubbers) is pretty easy to get at now, but I don't have an air pump, power steering pump or a/c compressor. The belt is a two minute job...there is about six inches between the belt and the frame rail. That makes the water pump a 30 minute job. Even the intake manifold is pretty easily removed. When I made the front lower engine mount, I had to remake it three or four times because I couldn't get the starter out without removing the mount. The final design allows the starter to be easily removed. Also, amazingly the alternator is not a mess to remove if needed.
I used all new accessories like alternator, starter, water pump, etc so that I would be good for a while.
Right now the gas tank is out of the car because I needed to do some welding to the shifter mounting bracket and needed to get to it from under the car to weld in new studs. At the rate I am going, I probably won't even be looking at the car again until this weekend at the earliest due to my shop's workload. I can't complain. Last year we were a lot slower than usual and this year we're making up for that.
If anyone is ever in the central NJ area and would like to see the project, feel free to stop by my shop and check it out.

If you wanted to use A/C (and maybe PS) would it still fit? (I know you don't want to for this swap, but it would be interesting if it were possible.)

Could you post some pics of the swap and shifter mount? (and more pics in general of the whole project. :P) We're in Cali are dying to find out how this awesome project goes.

The a/c is possible, but a non-vr6 compressor would have to be used. The VR6 compressor spins counter-clockwise. That is why the belt is ribbed on both sides. I'll post some pics as soon as I get it back together and after Joey does her first burn out.
The function of this car was to see how much hp a VR6 can make in a Fiero....so once the initial testing is done, the motor will be pulled and a built up, low compression engine (done with pistons and not a thicker head gasket) will be installed with a twin scroll turbo.

Nice car, Dave. Let us know what kind of 1/4 mile time you get.

Holy howlin' hannah...that thing is gonna romp!

Megafreakindeth, I think the TDI, even though it *can* make as much power as the VR6, *may* not be as good a choice, because of the density of the Fiero spaceframe---these cars are HEAVY for their size (my Formula weighed within 300 lbs of the Eldorado the 4.9 came out of) and the VR6 should provide more low end torque to move the car, even before any massaging on the motor is done, although the TDI's grunt down low is impressive, considering its displacement.
And of course, as a matter of taste, I think it's gonna be nice to see a 6-cylinder Fiero whose motor revs another couple of grand above what the GM 2.8 was capable of; anyone who's ever heard a performance-prepped VR6 run, will know what I mean...sweeet!
BUT, there is something to be said for a motor capable of 45-50 mpg while burning a fuel (biodiesel) that smells like french fries, lol...(People forget that Otto Diesel designed his engine to run on peanut oil.)...

I finally got the chance to put together another order of parts for this swap today. I got some mandrel bent exhaust pipe, weld in bungs, Magnaflow mufflers, and some goodies for my V8 Fiero and a few upgrades for my gold GT.
So hopefully I'll be able to post a video without the funny looking exhaust that is on the car now...and a much sweeter sound. The only part that I didn't get was the exhaust tips. I have a unique set in mind, but they are over $300 for just the tips (knock offs of the OE tips I want). The OE tips list at the dealership for $424 per side....OUCH!
I might have to agree with my wife and let her enjoy the car before I start making it really fast. I think I really would be happy with a fun to drive, high revving car that will take out most production cars from a stop light. That was the goal of my V8 Fiero...just a fun car to drive that is loud and decently quick.
Looking into the possibilities of this swap, we may have just opened a door for other VW swaps in the future...maybe a 1.8t with a K04 and GIAC, a TDI swap, a W8, or we can start playing with the new 2.0t or the 2.5 5 cylinder. Time to step into tomorrow.

If I could make a suggestion, do a swap that's on Ward's 10 best engines list.
http://en.wikipedia.org/wik...%27s_10_Best_Engines

I'd also vote for a DI (direct injected), or better yet, a FSI *hint, hint* ^_^ engine.

I think you should wait a few years though and let technology catch up to your talent.

What is the stock redline of a Vr-6 anyways? :curious:

What's the improved redline? How do you do that? (short simple version pls. )

I would love one of the new Audi or Honda type engines with a 8500rpm redline.
Especially with the sound of an Audi R8.
