Some old pics...cause i plan on redoing the plumbing, but this will give you an idea.
Garrett T3 super 60. .48 hot side, .63 cold side. Running 11 psi of boost with a ford probe intercooler (that i plan on switching for a dsm intercooler). Stock injectors, but cleaned and flow tested. MSD ingition, blow off valve, and other goodies here and there. Any questions, feel free to ask
just realized these are really old pics because i've replaced all the rubber hoses with silcon ones...so those have all been changed as well.

Interestingly enough I've been thinking of putting the intercooler in the trunk as well, but if I were ro go air to air I would worry about how cold air was to get into the trunk to feed the IC. Do you have some sort of venting? I would imagine that even though it's cooler it's still pretty hot compared to what it could be out in the open.
Lets see some more!

2.8 intercooled, trueleo Intake Headers Chip, MSD, Crane, 9:1 pistons and other engnine mods.
That's a shortend MR2 intercool with MR2 fan under it. And that extractor scoop really keeps it cool in there, thou I sometimes feel like I'm being followed.

Nice! Any more pics?

From what I understand, the response from the turbo not only depends on the size of the turbo but also how close it is to the exhaust and intake. Just something to think about.

I have my headers, Y-pipe, and turbo high temp ceramic coated. I also have the headers and Y-pipe wrapped and I always run a good turbo blanket. You want to keep the heat in the exhaust. There are a lot of factors that go into the response of the turbo. Hopefully the Dyno graphs will get posted after Daytona so people can compare the power levels and power curves of the different setups.

It does, to some extent.
STS Makes a Remote mount turbo System for the Corvette, mounted WAY in the back near the muffler. Turbo Lag according to Horsepower TV, is really not that noticable. considering the turbo in the Fiero physically is not far from the engine, it's not really much of a concern.
In reality, if you're expirencing turbo lag, you're not launching at a high enough RPM... the 3.4's 7G will be more than enough room to make power.
Keep it close to keep lag to a min, use an intercool to keep the air temp down, turbos make it quite hot and thus thin negating some of your boost. If dont want lag dont go too big with the turbo, the bigger the more lag. I have a small Garret and almost no lag, spins right up.

Francis, how many lbs of boost are you running? What trim of Garret?
What I'm looking for is efficiency in setup, I might go with a T3/T4 hybrid, and a water to air IC setup, with the heat exchanger placed Directly in the intake quarter. I want to reduce heat coming in, but also going out too. I figure with the Turbo out of the engine bay, this will help in some measure.
I'll have to ask my son which one he put in, Im thinking it's a T-27 but Im probably wrong. I know he spent a lot of time mapping dif size turbos to my requirements before he selected one. I'm only runing 7lbs now, but I have 9:1 or 9.2:1 pistions and had the shave a tiny bit. My son wants me to bump it up to 10-12lbs, but with the headers I made for it and our intake, Crane cam, head work, MSD, etc etc, it's more than fast enough to be fun. Every pound additional of boost puts more load on the engine, so.... but more power.. hmm.. Oh, I would not bother with a water/air intercooler. If your not going to go above 14lbs (i would not go above 10-12 with a 2,8 that you drive a lot) an air intercooler will surfcie fine. Just put a good size fan under it and maybe pull cooler outside air down through it like my setup and use scoop (dont have be as huge as mine) with a fan under it to extract that air. I have a thermostate on that extractor fan you see on my deck lid and my engine compartment never gets really hot. one other ques, are you going to Carlislie this year?

Unfortunately, I wont be going to be at Carlislie this year, it's a bit too far from Edmonton, and the wife and I have plans at around the same time to be in Ontario Visting relatives.
Right now, I have 3.1 Engine and drivetrain out of a Cavi, something I'm not planning on boosting, but the thought has crossed my mind. I'm prime for a 3.4 DOHC in which I'm looking to attain with boost a modest 300+ WHP.
All this is still in planning stages and probably will be about 7 months to a year away from being at all complete, with my current facilities.
I may still go water to air just because the setup I'm looking at is so compact, a desireable aspect with the cooling properties I'm looking for... it also means less clutter in the engine bay, and if at all I want to access anything engine related, makes things a whole lot easier.
If I do decide to boost the 3.1, I may be looking at your intake... for that efficency I was taking about!
thanks,
Sean

Mine was a 3.1 rebuilt blueprinted at 3.2 and adjustable turbo which they ran at 18lbs running race gas at one point.
Aftermarket ecu? what map sensor are you using? have any specific details abuot your A/W plenum?

I wish I knew-----I bought the car already built and it's changed hands three times since it was built. It only has 49,000 miles on it though. I believe the a/w intake was a one off. I don't know which ecm they used either. The set up was specifically built for uphill racing. The original SD4 was blown up racing supposedly. The car is an 85GT but was not registered until the mid 90's for street use.

I have Turbo Fiero, and there are some pics on my website. If someone want to post them. Still working on tuning, the weather here has not been cooperative.

I took a look at it, it looks like you've done a nice job with the setup!
