What is the difference between a

"GT28RS"

and

http://www.turbobygarrett.com/turbob..._472560_15.htm

I am getting sick of everyone using the wrong nomenclature and using trendy names instead of trim specs.

http://www.hksusa.com/products/?id=1672

btw HoneyWell Garrett MAKES HKS's turbo for them.

I'm just curious here.

the CHRA is what should name the turbo. Not the housing sizes.

ps. I hate disco potatos

they are simply a gt28R turbine wheel (same as 2871R) with a LESS efficent compressor wheel bolted to the front....

s13.dark1 · 02-11-2008, 07:11 PM

did u just answer ur own question or is there more to it?

bejota180sx · 02-11-2008, 07:37 PM

isnt gt28rs a disco potato?

McRussellPants · 02-11-2008, 07:41 PM

what did you think would come of this thread?

a well witten coherant answer?

I'd rather people call it the GT28RS than a disco potato anyway.

discopotato is ultimate in douchebag marketing ploy.

eastcoastS14 · 02-11-2008, 07:45 PM

lol disco potato?

like anything else with cars it gets said a few times in a magazine and suddenly everyone is saying it

sleepy_s13 · 02-11-2008, 07:48 PM

^^^^lol, nice............

"And whats the deal... with NICO? I mean seriously?"

PoorMans180SX · 02-11-2008, 08:30 PM

HKS's website indicates a .1mm bigger exducer on the compressor wheel. Maybe a slightly closer tolerance to the compressor housing? Or just an error.

But, HKS turbos have inconel turbine wheels. I thought that was the difference between HKS and one from Garrett, and the fact that they come with an HKS wastegate actuator. But I could be wrong.

And I thought HKS just named their turbo the GT-RS just to name it something other than what Garrett calls it.

kandyflip445 · 02-11-2008, 11:17 PM

HAHA, wasn't it SCC magazine that dubbed the damn thing that? Now the magazine is in the toilet and about to go under? (it may or may not be, but judging by the size of the issues, I'd say they are)

a "disco potato" is not a GT28RS

a GT28RS is a GT2871R with smaller housings

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.

!Zar! · 02-12-2008, 11:36 AM

gt2871r can built more top end power than a gt28rs

But then I'm not quite sure if I get the question.

steve shadows · 02-12-2008, 11:38 AM

Its The Same Turbo

Tell me how that is possible

!Zar! · 02-12-2008, 11:42 AM

Demonic hamster magic?

Now I'm interested myself.

steve shadows · 02-12-2008, 11:44 AM

Thats why I titled it the challenge.

They are the same.

The GTRS is just some stupid lingo drempt up to get shops more profit on the same exact turbo with slightly marginally different housings.

when i hear disco potato... the price usually goes down...

when i hear gt2871 the price goes up.

steve shadows · 02-12-2008, 12:40 PM

Disco Poato is cheaper because if would have read any of my posts in this thread you would see - they use a Super 60 T3 style Compressor wheel.

not the new technology that Garrett has hashed out in the recent decades using the GT series line up.

So it should be cheaper, substantially.

An S15 turbo in my boost is better than a disco potato. It makes as much rwtrq, with marginally less peak output.

johngriff · 02-12-2008, 12:42 PM

Dont hate on my compressor wheel! I'll kill you!

Its more then the housings. They both have differant part numbers for the CHRA:

The GT2871R also lists 3 differant CHRA part numbers, all have differant Ind. Wheel Diameters. And differant housings. The link below makes it a bit easier to compair turbos.

http://www.turbobygarrett.com/turbob...ison_sheet.htm

Also on turbos, If you guys want a GT3076R and GT3071R, you better buy fast from people that have them in stock. the price on the exhaust housings(garrett housings) went up $226.XX in the last month at my costs. Meaning, I can sell the GT35R for cheaper then the 30R turboes.

I would assume Garrett/Honeywell makes only the CHRA for HKS. Also, where did you find this out?

steve shadows · 02-12-2008, 02:29 PM

Yeah I noticed that too.

But if the whool size is the same overall then the inducer is the only difference in CHRA?

Thats the challenge. I want this clarified.

How am I? Your setup is like 1/2 as expensive and better matched to your engine.

haha It's a compliment

KA-T_240 · 02-12-2008, 02:37 PM

If you pay for them, I will order in one of each and get down to the nitty gritty and take lots of detailed photos and measurments!

Wait, whats a Whool?

Slow Poke · 02-12-2008, 02:46 PM

Sorry I only skimmed through the thread and gotta run but I just wanted to say that the 28rs and 2871r are not the same. And even if turbos had the same chra there is no good reason why we should ignore the housings and give them the same name. Housing are very important as well. I'm not sure what you are trying to get from this thread? If you call Garrett they are usually more then happy to explain any differences in turbos.

And Garrett only produces the HKS CHRA's not the housings. Also there to HKS spec and NOT Garrett's.

steve shadows · 02-12-2008, 03:01 PM

So spill the beans how are the WHEELS on the "GTRS" and the GT2871R

different?

What are you holding back?

KA-T_240 · 02-12-2008, 03:07 PM

What is to say that they are the same?

steve shadows · 02-12-2008, 03:15 PM

Did you read my OP

Compare the Diameters, Trims of both wheels and other data provided.

Both on garrett's website and elsware.

My point is there is no such thing as a "GTRS"

and the GT2860RS is not the "GTRS" everyone is talking about

The gt2860RS is a GT28R with a Super 60 wheel aka the disco potato

the "GTRS" is in fact the GT2871R with T25 Housings.

KA-T_240 · 02-12-2008, 03:23 PM

Yes, just because it is the same size and the same trim doesnt mean its the same.

The shape and curves on the fins of the turbo could be differant, one could have more fins.......

HellonFire · 02-12-2008, 03:24 PM

Ok, I had this EXACT same discussion a long while ago with a Garret Rep. Between him, me and him calling Garrett direct, he figured out that the "S" in GT28R"S" means "Special". That turbo was made specially for nissan during its racing days. Let me see if I can find what I wrote about it, becuase I honestly don't remember everything anymore.

Tyler

KA-T_240 · 02-12-2008, 03:40 PM

According to the Garrett website S on the end reffers to a S-cover compressor housing. Which is made for high flow applications.

yeah its gatta be in the compressor wheel design....
compared to the normal t25 compressor housing, HKS's compressor housing has a slightly different shape, no? I thought it extended a little bit more, helping the top end of the rpm range, where with the normal t25 housing, it (power) would fall off a little bit.

good thread though steve.

one of very few worth looking at. +rep
