I have no clue what it actually is because the only thing on the Turbo is Garret M24 ar.60

It was $202.50 shipped....

Brand new!

The inlet is 3" and out is 2", The inducer is 57 mm

And its got some wacky exhuaust housing, but its gonna work great for me! The word on the exhaust housing is "PRECISION"

The turbo wheel exducer is 55 mm.

wow, that thing is huge, call me when you get it to spool.

Pretty sure now that is a GT30R

Goodness Doug... You just don't do anything small do you .

Are you going to use this to replace your supercharger setup?

Either way, I can't wait to see the installed pics.

I feel like Doug has more forced induction setups than he does cars....

I sure wish I did....

(turbo envy)

I'm pretty sure all GT series turbos are watercooled. That looks to me like a T4/T3 with a custom exhaust side. Pull off the downpipe section and take a pic of it. Is it 5 bolts, or 4?

How'd you end up scoring it for that cheap? Is there any axial or radial shaft play? I'd be concerned about either shaft play or leaking seals if it was that inexpensive. But, good deals do come along every once in a while...

The inducer is 57 mm...The turbo wheel exducer is 55 mm.

Where are you measuring these? The inducer is the smaller, outside edge of the compressor wheel and the exducer is the larger, inner edge of the compressor wheel. Fire off these two measurements and we can figure out what compressor wheel is in there (the 55mm & 57mm measurements don't match up to anything).

It's a Buick Grand National turbo put out by Precision Turbo & Engine

YOu must be excited since you said, " its got some wacky exhuaust housing, but its gonna work great for me" twice in a the same post. Do tell what you plan to do with it...

The turbo will feed the SC. I want to get about 20-24 psi. Obviously the turbo could do that on its own, but spooling is going to be an issue. The SC starts at 8 psi at 2000 rpm, is at 11-12 by 3000. So with the Turbo thrown in it should hit the 20's fairly quick. And since the turbo is so huge, the air moving should be on the cooler side compared to a smaller turbo that is working harder to move the same amount of air.

Compressed air into another compressor is more than 1+1 = 2, The turbo should only have to move 8 psi into the SC to get 22 psi out total. Or so says the math.

But if it doesnt work, so what, at least I tried it!

Has anyone told you that you are insane, but in a good way insane?

hey doug, here is another ebay Ad, this is what his GT30R looks like:

How many engines do you think he'll go through perfecting this setup?

no less than seven?

Hey now....


I may blow this one up, but it will only be because I will be making 300 plus whp!

Precision huh? They make a good turbo.

I'd be willing to bet they carry a V-band outlet flange for that exhaust housing. Bolty-Bolty!

Your going to feed the SC with the turbo?

Why not the other way around? Feed the turbo with the supercharged air. Isn't that how the HKS Twin-Charge kits for the old SC MR2's worked?

That would make sense to me, allow the pre-pressurized air from the supercharger pass the inducer fins. should help eliminate some of the lag no? But as we've all seen, Mr. Vincent is almost incapable of doing anything that would be considered "conventional" or "normal."

Good Luck, and I wish it the best. Keep Us posted!!!

It doesn't really matter, it'll be worth it.

It will work......

How well?

Thats another question....



However, one way or another, I am going to make some amazing power.

Doug, your my G-Fab Hero.

Now all you need is my Autometer Lunar gauges!

I got my welder working tits today.... Turns out it had smaller diameter wire than required.... I wanted to chide my father, but since he's dead, its kinda hard

BUT!!!

I bought a metal chop saw and am set to go for building my uppipe and downpipe!

This turbo is going to rock!

gt32 FTW......... Only cool black cars have those turbos...... Well at least yours will move.. Mine is the prettiest driveway garnish ever!

I think you're missing a couple of pipes there...

and i thought changing my plugs are a bitch hah.
