The closest that I can come is using a Mitsubishi turbo on a push rod 3.4 turbo installation. My side scoop is now functional as a cold air intake that will hopefully somewhat improve performance. I used the 19 pound Ford injectors and a customized fuel table to handle a very rich fuel burn issue and have limited the boost to around 7 psi for long term reliability. An intercooler would also be useful but I do not have one on this vehicle.
the TGP stuff would probably work, but be far from ideal, that turbo is small on a 3.1l....

I know turbocharger is small. Budget build. Already have all these parts. Just looking for history at this point
the TGP 3.1 swap has been done before, but not a 3.4 with the tgp hardware that I am aware of.
well, here are my thoughts: power output will probably be about the same as a tgp, you're taking a downgrade with the 3.4 heads and Fiero intake, and the turbo will max out quickly.
you mention budget, you could probably make more power with a stock 3400 or 3500, for a comparable amount of work.
all that being said, I'm pretty sure the 3.1 uses a slightly different exhaust manifold flange than the 3.4, so the manifolds might not even work at all.

The TGP manifolds won't even bolt up to iron heads, will they?
I don't think so.

I turbo'ed a 3.4 to about ten psi. Was fun to drive, spooled up around 3k and could be a problem going around a turn. I had a heck of time getting the idle right. That was the problem, tuning it all. 80's technology was just new to fuel injection.
my experiences with a turbo 3.1 were with a KKK K3 turbo from an 80's Volvo which is about equivalent to a T3. I had lots of torque from 1800 rpm on but I believe I ran out of fuel at 4500 rpm. I was at 8 pounds of boost. It was a member's car which I bought. Adjustable FPR with fuel pressure dialed up. It was using a Buick ESC control module. A knock sensor was added to the block and running an expensive MSD ignition. Not the stock looking coil most people swap out. Running a stock 87ECM but I can't recall if it was chipped... The Buick ESC module dialed back the timing on the ignition from knock sensor input. I forget what injectors were being used.
I had various issues with it all within a year and eventually replaced it with a Fiero Factory 4.9 installation and sold most of the turbo specific hardware to another forum member. I of course regret that now. The 4.9 swap was it's own nightmare. The turbo 3.1 made more power...just not as reliably/consistently...
For a 3.4 - get a T3/T4 hybrid or go full T4 or equivalent...and a proper ECM to control it and do your homework on fueling.

Since it is coming from a GEN2 3.1, the exhaust ports are probably round (someone please check). However, the manifolds may still not line up when re-connecting to the cross-over after mounting them on iron heads, if that's your intention. If they do, please let us know...if that's your plan. That setup could form the basis of future kits if it does.

they are round, but the bolt pattern for the gen2/3 exhaust flange is taller than the gen1, so they won't bolt on.

it's not impossible, but they are beefy cast iron, machine shop job for sure.
