Garrett GT32

I know its common to use the GT3071 and the GT3076. Not to mention I've seen people use the GT35 too. But has anyone tried using the GT32?

Supports up to 420 hp. Compressor: 71 mm, 52 Trim, 0.50 A/R. Internal wastegate optional (at additional cost, does not include actuator) Oil cooled.

The price isn't bad either...

http://www.boostplanet.com/gt32.htm

2.3l B204 top mounted manifold and this would definitely make good numbers. I don't know how great the spool up on a 2.0l would be.

I believe Jak tried some variant of a GT32. If you search you may be able to find an old dyno sheet of his from that to tell you how it spooled and maybe what specific one he used.

That site doesn't give much info about the turbo, unfortunately. Just go for it and see what happens.


I did just read that the compressor wheel is a lot smaller than that of a GT30. I think above all you need to determine how much power you want to make. Or are you just wanting to try something new?

Jak ran the gt32, it made pretty good power, about 380whp with petro and stock cams. He made 400whp with a little shot of nitrous and then one time made 431whp on a "in my opinion" low reading mustang dyno with a 125hp shot of nitrous.

Last thing I remember, he was doing a 1/4 mile dyno run on the mustang dyno and the nitrous soleniod stuck open and he had a nitrous back-fire and by the time he turned off the bottle, the motor and wiring harness were pretty well melted

Then his wife's car popped out of gear and rolled down and smashed into the front of it as it sat in the yard.

Not the best luck...

Is there a clear list of oil and water hoses to get these GT series turbos to work.
I am planning down the line when I deem my clipped Td0418t6cm too small and want to upgrade.

Depends on the turbo really, some (like the one in the original post) do not have water cooling. Either way, you just find the correct size threads for the inlets/outlets and go to summit racing or ANplumbing.com and get what is needed. There are plenty of threads about what sizes are needed for the fittings on the block, they are going to be either M14 or M12 I believe.

did anyone get an idea on when this would spool on a 2.0 with say a 3in full exhaust? I doubt this turbo would ever hooked up to a stocker unless you like melting things.
