Turbo Identifcation,

[Jorrs]

hey guys, i have a turbo i will be putting up for sale, but i cant identify whether its a GT30 or a GT35, its not on me at the moment as its in storage with other bits and pieces and i only have a couple camera phone pics, couldnt find it identified on the housing either.
its of a project my mate and i were going to go ahead with, but have now given up on, and i am unable to get better pics for a few days.
Was all bought second hand and was told it was a Garret GT35.
any help will be very helpful, as i am about to put it all up for sale.
cheers







it was all bought from the states as well. made for a B16A motor.

[-==L=a=N=c=E==-]

just looking at the size of the compressor, i'd say it looks lie a GT30.

But to hard to tell from these pictures.

ahhh yeh, this is some of the info i had on it.
Upgraded Garrett turbo (new) 60-1 W/ 70-1 HOUSING capable of 500hp w/ smooth efficiency. (Smoke free turbo) Should spool fully at 3,000rpm.

[-==L=a=N=c=E==-]

not really that much help...

only way you will know, is either measure it up, or grab the serial number off it.

[Jorrs]

ok, ill see if i can grab the serial number of it next week.

Ok, it's not a Garrett GT. The 60-1 number gives that away. there's a good chance it's from the TO4B series and here is it's compressor map:



To generate 500hp you need to pump ~60lbs/minute (0.35m^3/s.) Using my spreedsheet (and a 1JZ-GTE as a test example) we can see that yes this turbo has the potential to make 500hp (375kW) at 8800RPM on 22PSi (not un reasonable figures.) It is likely on a 1J that this turbo would spool up between 3500 and 4000RPM

oh yeh, i think ill need to get a better look take more pics, i was just hoping someone might recognise it.

Its hard to tell without measurements but i dont think it is either. The compressor wheel looks far too small for a 60-1 (plus doesnt have same amount of fins/ blades) let alone the big burtha the GT35 / GT3540.

Here is a couple of comparision pics. The first is my old T60-1 and the later is the new GT3540







It is still hard to make the size out from the pic but the first turbo pic is the T60-1 with a .6 A/R comp cover. The inlet is 3" and you can see that the compressor wheel uses almost all of that 3'inlet !!

The second is the GT3540 it uses a .7 A/R comp housing and the comp wheel on this puppy uses almost all the 4" inlet too !!

[Jorrs]

definately not the 35 !
so 30 perhaps ? or a t4 variant ?
i will get sum measurements next week, and a serial number of the casing.
hopefully then i can put it up for sale wit hthe rest of the gear, what kind of money would i be lookin at ?

[jfallen]

depends how Chinese and oil cooled it is?

The less Chinese and the more water cooling the better. BB even better.

Measurement's that will help identify are the: the conmpressor/turbine major and minor diameters, as well as the A/R of both the comprssor/turbine housings. There's a good chance these will be printed in it's itentification plaque.

P.S: remember that there are many different compressor housings avaliable, to which you can fit any compressor wheel.

I would just sell it as a T4. You could spend ages trying to work out exactly what sort it is.

Depending on the condition of the bearings IE shaft movement i would expect you would get $400-500 mabe ??

[whatthe?]

What flange does it have? Gt30R and GT35R are both T3 flange. If it's a T4 flange then it's most likely a T04 variant

[30psi 4agte]

looks like a t3 flange from the pic. The front looks T4 though.

[whatthe?]

I dont know, without being able to see the side of the flange it's a bit hard to tell...

[Jorrs]

thanks for help guys,
its a Garret M24.
now i can put it up for sale.
cheers fellas.
