I was wondering if anyone knows what type Garret turbos are in the APS TT kit?

Thanks

 

I believe they are GT25's with a 38 housing

 

yeah i think thats right, bigbri and i got into an argument about it a while back, i think he said that was it.

 

I thought they were Garrett GT2535R's or something like that, I don't remember the 2538 but I could be wrong.

 

They are GT2835R. The compressor housing from the GT35R and the turbine housing from the GT28R.

I think they should have just used a pair of GT28RS off the shelf instead of a completely new hybrid.

 

We are both wrong - I dug and found the correct info:


The turbos are Garrett GT2535R Water-Cooled Ball-Bearing Turbochargers
It is a new hybrid specced by APS for Garrett to produce to match the VQ35DE. What the alphanumeric name means is, the turbine side uses the GT25 housing and the compressor uses a GT35 housing.

 

Thanks for the help!

So, I could get the GT2535R turbos straight from garrett, correct?

 

I was told by APS that the turbo is a GT2871R, using a specialized compressor cover. Is this the new nomenclature used by Garrett?

 

That turbo is the turbo used in the ST setup, not the twin,

You cannot get these (GT2535R) direct from Garrett. they are made solely for APS

 

You are right- this is too confusing:
"APS twin turbo system are actually a GT 2871R, the turbo model terminology was changed by Garrett approx 4 months ago"

 

dammit, now hold on, i was told the aps single was a GT35R.

 

This info above I stated was incorrect.

The TT setup runs GT2535R turbos which are now called GT2871R

"APS twin turbo system are actually a GT 2871R, the turbo model terminology was changed by Garrett approx 4 months ago"

 

I'm a little confused about this as well the pic on there web sight looks identical to a GT25R Compressor Housing Note the "M24" designation



Can any APS owners or dealers shed some light on this I looked up a GT2871R and a GT2835R, they do not look like the turbos on the APS website...

 

When David from APS visited us at Enjuku Racing, he informed us that the turbo was a GT2871R but he was using a compressor cover from that of a Skyline GT-R N1 due to the nature of the compact design that the turbo(s) required in this particular application.

 

The turbos are a hybrid GT25 turbo with a GT35 compressor housing. The original tech name for it was a GT2535R, but Garret has updates its litterature and it is now labeled as a GT2871R.

The original info on the turbos:
"The turbos are Garrett GT2535R Water-Cooled Ball-Bearing Turbochargers
It is a new hybrid speced by APS for Garrett to produce to match the VQ35DE. What the alphanumeric name means is, the turbine side uses the GT25 housing and the compressor uses a GT35 housing"

As an update, I was provided with this info....directly from APS:


APS twin turbo system are actually a GT 2871R, the turbo model terminology was changed by Garrett approx 4 months ago"

The reason you are having a difficult time finding more info from Garrett is the fact that these turbos are manufactured exclusely for APS for use in their kits.

 

Side by side...the compressor housing is IDENTICAL to a typical GT25...this is why I am confused.

 

+1 Exactly... I was @ the Garrett Both @ Sema AC last year... There is a significant differance in size as far as the compressor between the 25 and the 35 (now the 71?) + 4 of the sales reps were not aware of a custom turbo set up for APS.... They were only familar with GT2835R set up for HKS... Which was on display at the booth... Not trying to call any one out... Kinda makes you wonder....

I'd like to know why on the compressor side the APS turbo is indentical on the outside to the GT25R? It would be great if some one from Garrett could address this... Someone has to have access to both turbos...

 

First off, the '71' is just what it is called. has nothing to do with the size of anything


Second, why does any of this really mater? You know the capabilities of the turbos and how they perform.

 

Just curious I guess the APS/Garretts have nothing to prove. They perform well...

And to me it does matter if a manufacture claims something, and there is conflicting concrete visual proof it may be something else...


PS Very clean car.... I love my SPX177R's

 

It's possible that the trim, and interior of the housing has been modified to flow like a Gt35. I doubt APS would have any reason to misrepresent the turbo, but I too would like to know exactly what it is.
