Turbo 3.4L

[LuckoftheGTP]

Does any one know if you can put a turbo from a '89 TGP into a 3.4L DOHC? If you can you think the engine could take the extra power?

Turbo would be too small.

 

And, 3.4's have been turbo'd already.

[meltboy1]

what about using the crossover and maybe upgrading to a t28, would that work on the 3.4?

[GOT2B GM]

No. totally different engines.

[meltboy1]

I know they are different engines...lol but what I didn't know is if they used the same exhaust manifolds...

[GOT2B GM]

not even close. You could bolt TGP exhaust manis onto a 3X00 with some porting of the manifolds.

[meltboy1]

ah cool, thanx for that tid bit of information

my plan has always been to block the exit on the rear manifold and run a new down pipe. and cut the Xover and mount the turbo.that way you save the money from makeing new exhaust manifolds.... sadly on the 96-97 we cant use a front manifold on the back. like the early years

[ismellrealbad]

the manifolds/xovers only changeover between the pushrod 60*s because the ohc heads are much different.

You can always take an extra front manifold, cut the flange off, and weld on a new flange. That's what I've done for my new setup.

 

The 3.4 DOHC can handle boost. Anything from the T2X series is too small. Many T3's are too small. A T3/T4 hybrid is going to be a better fit than a straight T3 (straight T3's are fairly difficult to find anyway). There are a lot of nice turbos in the T4 size range, but you will have more lag. The GT30R is the smallest newer turbo I would consider running.

GT35R would be nice

 

i've seen one on a 3.8L w/ heavily ported heads and intake.

 

well, the 3.4 flows better stock than a 3.8 could ever wish for......so a GT35R would be good.
