A Challenge...

Thanks

Just wanted to clear it up for myself as well.

Ok, but there is NO GT2871RS.

This is what I found out, quoted from another forum.

I called Limit Engineering and Turbo's Direct as listed on the distributors section of Garretts site. They were the only ones open.

Limit Engineering said that the S specifically stands for the "Hose in, hose out" configuration of the turbo. Or also called "Slip Fit" Meaning it has no flange, like another turbo might have on the compressor housing, you can just use a coupler.

Turbo's Direct agreed with what Limit said, without me mentioning it. But also noted that he wasn't entirely sure that was all the difference and is going to call Garrett later and get back with me on exactly what it stands for. Because, if the S did stand for that configuration, then why wouldn't' the GT2871R and GT2876R also have the S because it is the same type.

So.. There you have it.

UPDATE:

Well, Turbo's Direct called me back. He talked directly to Garrett. This is what they said.

The S, was originally supposed to stand for a single port wastegate actuator. But, since most of the turbo's that they started making were only single port, they dropped the s, and never applied it. But then since the GT2860RS, was made specially for Nissan for racing, the designer of that turbo put the S back on there just to specify that it was a "Special" turbo. And thus, the only difference in the GT2860RS and GT2871R is the slightly larger compressor housing/wheel.

I know there is not a 2871rs. I was referring to the S on the gt2860rs

[HellonFire]

Well like I said above. According to Garrett themselves, it stands for "Special"

Steve Shadows - I hope you also re-read your OP, because it clearly challenges everyone to distinguish between a "GT28RS" vs a GT2871R.

The "GT28RS" is what many people call the "Disco Potato", and is indeed the GT2860RS.

The "GT-RS" is the HKS turbo, which is what I am assuming that you wanted people to distinguish between with the GT2871R.

Just thought I'd point that out, because I think your OP confused some people after they posted about the "Disco Potato", aka the GT2860RS, and you blasted them for bringing it up, but in your OP you clearly put "GT28RS", which is not the HKS GT-RS.

^ No the point of this thread was I was pissed everyone was touting GTRS

numbers as the disco potato not knowing what they actually purchased was a gt2871R

The problem is all the fanbois use the interchangible like the GTRS will make 400whp! wow

or the GT28RS will make 400 WHP! wow

Find me a gt2860R on a 2.0 SR making 400whp...

a "disco potato" is a GT28R Turbine wheel and housing with a Super 60 (antiquated 35 year old) compressor wheel (T3)

Hence this thread to educate people like you about things like this.

Wrong. It has nothing to do with the housings whatsoever.


A GT28RS is the "old" name for a GT2860RS - a NS111 53.8mm major dia. turbine wheel and a 60mm 62 trim GT series compressor wheel.

A GT2871R is the same 53.8mm NS111 turbine and a 71mm compressor wheel that can vary in trim(48, 52 - what you linked with the T04B comp. housing, and 56).

A T28 - S14/S15 turbo - whatever you want to call it is a GT2560R. It uses a 53mm major dia. turbine wheel and a 60mm major dia. 60 trim compressor wheel with older aerodynamics than the GT2860RS. That's why it has about 10-20 rwhp less power potential than the GT28RS/GT2860RS. I agree it's a better turbo given the cost though...



And to further edumacate - what was called a GT25R/GT2540R is now a GT2876R - 53.8mm NS111 turbine and 44 trim 76mm compressor wheel in a big T04S compressor housing.

So what is the difference between the "HKS" GT-RS and the GT2871R? just different housings? the HKS one is supposedly faster spooling isnt it? or is my memory just laggy....

[McRussellPants]

HKS is the same as 52T 2871, maybe different covers count if you're trying real hard to convince yourself that paying 1k extra was worth it.

I dunno what hes getting at.

Right, which is the disco potato right? (I fucking hate SCC)

The old GT Compressor wheel has a different compressor map than the Super 60 T3???

Then SCC and Garrett's disco article is all wrong
