Drove 3 hours yesterday to go pick up what i was told was a gt35r which turned out to be what he said was a gt35 journal bearing. I've never heard of this and he says he bought it from a place in Texas and is sending me the invoices. He also told me that it was custom built for him by the place he bought it from. Im still really not sure what this is, please help.

 

that's a gt35

 

Those wheels look a bit small for a 35r. Take the covers off and measure ind. and inducer /wheels

 

3" compressor, 2 1/2" exhaust

 

bump for info

 

Take the covers off and measure the MAJOR/MINOR diameters of both wheels.

 

the what? sry a little unclear about what im supposed to measure

 

You must measure the wheels with the COVERS OFF ONLY..





You need a caliper to measure these items. That is the only way you're going to know. And a GT35 journal bearing has SIMILAR characteristics to a GT35R. The aerodynamics of the exhaust wheel and the cartridge are what changes things.

 

i actually just got my GT35r in the mail today, i'll take the unknown turbo to work tomorrow and get a measurement. Thanks Shodan for clearing that up.

The 3" measurement is the exducer measurement on the compressor and the 2 1/2 is the exducer for the exhaust

 

that looks like a baby kahuna

 

not a GT turbine wheel

 

So this is what he just sent me in an email:

"Garrett GT4088 Journal Bearing. Compressor housing is slip on 4" inlet with anti-surge ported shroud and compressor outlet is 2.5" slip-on. ATP Special Exhaust housing with a T3 Flange with standard 4 bolt into a easy downpipe compatibility and plug and play replacement for older large frame T-series turbos. Largest trim available in GT40 family capable of making a healthy 700+ HP setup.

Exhaust Turbine A/R .63
-Wheel: -Maps: Not Available

Compressor
-Wheel: A/R.70
-Maps: Not Available
custom built GT4088 turbo
Engine Displacement 2.0 to 6.0"

 

MAYBE.. just measure the wheels, player... then you KNOW.

 

thats such a tiny compressor wheel for a 35 or a 40....

 

Or maybe just send an email to garrett with the serial number. They will tell you exactly what it is.

 

alright, i apparently shouldnt have skipped so many math classes this semester but if someone could help me out that would be awesome

Compressor:
Inducer- 50.52mm
Exducer-74.94mm

Exhaust:
Inducer-46.1
Exducer-84.88

 

looks like you have the exducer / inducer backwards on the turbine side.

That is DEFINATELY not a GT4088 in either journal or ball-bearing, and the turbine wheel is very large with a compressor wheel smaller than a 46 trim t04b, if your measurements are correct. that's about 38-45lbs/min. Looks to me like you got sold a tractor turbocharger made for super low torque, not top end,... like a Diesel.

Again, this is if you went and dusted off that math book and started re-reading chapters on how to measure and it was done correctly.

Please don't ask "what it'll do for me..." you won't like the answer on most applications.

 

i even think tractor turbos are bigger than that at LEAST by an inch

 

I will double check my measurements tomorrow again. Doesnt really matter what it will do for me as i have a gt35r i will be using. this i either need to try and get a refund for or sell it.,

 

What did you pay for this unit? I would have gotten definitive proof of the turbo's specs before buying if this were for my car...just a thought. Good luck

 

When he gave me the part numbers all google gave me was a turbo out of an Isuzu diesel truck. Like a commercial truck. Think it said 88-91.

 

okay so my numbers were off due to a low battery in the caliper

Compressor:
Inducer- 54.61
Exducer- 74.98

Exhaust:
Inducer-46.22
Exducer- 64.40

 

That seems like a stg2 garrett turbine with the exducer (small diameter) reduced to fit the housing... Usually they "clip" the inducer instead, so that's odd as hell. The GT3271 is the closest turbine at 64mm, but it's exducer is ~55mm.

The compressor is about what a 46trim t04e would be. That's also roughly the same size as the majority of ebay turbos, 2" inducer/3" exducer. Oddly enough, I recently PM'd BLAAST Performance to see if they could get that 4" ported housing for a 50trim wheel (pictured below). They replied that they'd have to machine it, since it only times in the 57trim and 46trim sizes. Your "anti-surge" has no groove cut into it, either.

Look familiar? (btw I'm not saying it's a BLAAST turbo)





Long story short, it sounds like a custom mix of JDM & CDM Garrett parts, and baaarely capible of 400hp on race gas. Do not want.

 

Your Kung Fu style is very good!!!
