3.1 L Turbo Set-up

[Dean]

Is there any documented information on the GP Turbo that was built in the middle 90s? I am curious to see what GM used as fars parts and routing. I wouldn't mind doing the same for my '96 3.1L GP.

Would anyone have this info?

Thanks!

It was '89 and '90, and there is info around, in these forums and W-body sites. I believe there's also info in teh family tree, and pushrod sections to the left.

Here is one bolted to a 3.1

But of course it is aftermarket...

the 3.1l turbo motor was built by mclearen in 89-90 and was in grand prix "TGP" cars. it was basicly a stock 3.1l motor (some will argue about some parts being treated and such, but the part numbers are identical to the na motor) but with a turbo. i beleive it was 205hp. it used a fiarly small t25 turbo

Here's a thread from the W-body board that outlines some of the differences between the Vin T & Vin V engines.

EDIT: As far as "routing" goes, this is how they look stock(I have a cone filter placed on the stock turbocharger instead of the stock airbox/ducting that would be running across the front of the engine/under the dogbone engine mounts up front there).

I can probably dig up some pictures of the turbo 3.1 out of my service manual that show how everything is placed/routed as well(I'll post them if/when I find them).
