Turbo for 2.8V6 in a Fiero
Michael Adams
0-60 was 5.3 seconds, and the quarter mile was 13.3. It was an awesome car.
Turbocharging system design is not to be taken lightly. It takes research,
a lot of trial and error, and money to get an optimized system. I hate to
sound harsh, but if you are worrying about the cost of stainless tubing,
then this is probably not the project for you. There are many other factors
such as sizing the turbo (usually much trial and error), exhaust system
fabrication, intake system fabrication, vacuum system changes, fuel system
modications, ECU calibrations, etc. Can it be done? Yes. Is it like
bolting on headers? No. A wrong move, and your engine is history. I would
also rebuild your engine, and put new forged pistons in it which are up to
the job.
By the way, we used a single TO4 turbo.

consideration as the fact that I see NO need to buy 20 feet of it when I
only need 5! I've got some friends that have done turbos to their cars as
well, but I am not one to just leave well enough alone and copy theres. I
know it's best to rebuild the motor FOR turbocharging, and that is my
ultimate goal as the motor in my 87 GT needs a rebuild. However, I am taking
the automatic transmission and cradle out of an 84 and the V6 out of an 86
for the time being just to get this thing going, then <eventually> I will
rebuild the motor that is currently in my 87GT specifically for
turbocharging. What did you guys drop the compression to, what kind of rods
did you use <I understand pre-67 SBC rods can be used with minimal
machining> and, most important, how much boost did you use?
Regards ECU and electronics-- I am going to use a MSD Boost Master ignition
control unit,MSD A6 ignition, and <if it will work with the above> my
existing Accel Supercoil. More than likely use a Turbo Timer as well.
Already have a source for a turbo-specific EEPROM chip for my ECU. I'm sure
I will have to upgrade my injectors-- currently researching that. I am told
that I can use SBC injectors as well- not sure though. Also doing more
research on the feasibility of using 1.6 ratio rockers to let her breathe
better- got any input? On the cooling side of things, I'm also gathering
info on the necessary water and <if needed> oil cooling needed. This will be
a challenge, as the engine is after all in the back of the car, in dead air.
I'm thinking of going with a set of those "over the roof" scoops that go in
place of the engine grilles, with some sort of bracket to mount IC on left,
and auxiliary oil cooler on the right.
That's about enough for now- just wanted to let you know this is not
something I expect to be a 1-weekend project. The car is not a daily driver
at this point,and the wife's been nice enough to give the project her
blessing as long as it doesn't take all the money <this is why I scared up a
free 84 from a buddy so I could have the cradle and transmission-- not to
mention the super-straight interior which just happens to be the right color
to replace my GT's interior ;> > I know I am in for a long trail here, but
that's something I enjoy :>
Anybody got any advice on anything I've said, or anything else concerning
this?

end up outside of the block? <G> In a Fiero book that I have (I think Michael
Lamm was the author) it mentions the Turbo V6 as having blown up. I do agree
with your insights as to all the mods that need to be done. Nice to be able to
chat with someone on the "inside" I have been a mechanic for over 20 years
myself and used to drag race Pontiacs (with real Pontiac V8 engines!) Ever hear
of Nunzi Romano? -ANT

I just happen to have the same, exact, car... except the 4spd.
I have a 5spd on the engine stand, waiting to be put in,
and a T04 wrapped in plastic while I, too, research this.
Perhaps you can ask around on alt.autos.fiero, and visit
one of the gurus of the fiero ring, the Pennock site...

I don't recall the thing blowing up, but who knows what happened to it years
later. It was specially built with an aluminum block. My memory is getting
kind of fuzzy on the project now, since it was so many years ago. I think
the compression ratio was lowered to about 8:1. Boost was not all that
high, as I recall...about 9 pounds. It did have some lag, but the goal was
high horsepower and low exhaust restriction. They didn't want to make the
same mistake they made with the Turbo Trans Am.

You mean when Pontiacs were Pontiacs? ;-) The good 'ole days.
To anyone thinking of building a Turbo Fiero, if you have the time and
money, go for it. It was an awesome package, and I still think the Fiero
would be around today if they had built the turbo car. We also built a
turbo V6 6000 STE. The Turbo Fiero got canned by Corporate, because they
did not want it competing with the slower (at the time) Corvette.

Did he actually get to see "Pop" Kennedy's tail lights or did he race in a
different class? It is interesting to note that the quickest street Pontiac
ever (1/4 mile) was powered by a Buick engine!

Please pardon me while I have a bout of projectile vomiting. Nunzi was a big
force in supplying some of the fastest Pontiac engines thru the 60's. He has
(had?) a shop in Brooklyn NY and had some very rare factory one off
experimental stuff. There was a letter from pontiac themselves "declaring" him
to be THE Pontiac expert. -ANT
