R33 Gts-t Turbo Recommendation

[Ruffels]

yeh huge differences between nissan 6 bolt and garrett 5 bolt!

i wouldnt be comparing a 6 bolt 3071 to a 5 bolt 3076!

[TUF250]

just after a rough figure, but 'roughly' what does it cost to highflow and rebuild the rb25 turbos?

Have a read at hypergear's latest update with the ATR43g3. Very reasonable response for 303rwkws. And that is internal gated on a stock standard engine with all factory gears.

That is fairly false, while a good upgrade the majority of results see no where near 300rwkw from the high flows.

Most people see 230-240rwkw from a high flow, dyno results thread to back.

That depends on the type of rear housing that we get to do the high flow as well as the combination of wheel we use refer to customer's driving ability. I've personally tested a .63 PU high flow maxed at 295rwkws, Roller dyno, 98 fuel, tuned by Dr.drift.

How ever the ATR43G3 mentioned is a brand new turbo that is made and proven for 300rwkws application, with 65kws more mid range then the KKR560. Plus controlled run is based on fully standard setup without boost controller or any thing that could advance its original response and power behavior.

yes very good result, these figures are with an aftermarket comp housing, chra and rear housing.... , so as stao said, those are a completely aftermarket turbo... not a highflow

[R31 POWER]

HkS 2835 PRO S kit or a 3076R. Just look at Hamish and Simons set up!

[Harey]

what boost tho? the 3076 will do same power and response times... but less psi needed to make same power.

its not fair? on who? haha as i said ive had both turbos on rb25's so just posting my experiences.

Its not fair on the poor old 3071

I am challenging this statement:

"what boost tho? the 3076 will do same power and response times... but less psi needed to make same power. "

A 3071 will have better response than a 3076 with same rear housing. The 3076 will have more top end power.

[Simon-S14]

true.. i should have been clearer. When we're dealing with the 3071 with a cropped ex wheel and a OP6 style or AVO style rear housing and internal wastegate as opposed to the 60mm garret 4bolt ex gate housing... the 3076 comes out top there.

the 3071 with the same garret 4 bolt rear housing is a different story since it has a 71mm wheel as opposed to 76 it will spool earlier for sure.

Bush bearing combo would be 800-1200

Proper ball bearing unit would be 1600-2200

Many factors involved from who does it, what specs and so on.

Personally, I'd go the ball bearing everytime.

i have a apexi ax53B70, had it tuned the other day and made 240kw on 18psi with 555cc injectors, pfc, z32, 3" exhaust, fmic. but was told i wont get any more out of it. pretty annoyed as i spent just under 2k on it and was told i would see 250 with ease. although i am very happy with the response

how much does a 3071 go for?

[HEKT1K]

how much does a 3071 go for?

I got mine from Kudos Motorsports. I wanted the whole kit (dump, lines etc) and theirs was the cheapest i could find

[Harey]

I think the HKS 2835 Pro S turbo wins the prize of most responsive turbo to make 275rwkw on 98 fuel.

Yeah just had a look, not a bad deal.

ooooo it has an option for the anti-surge compressor housing. did you get that?

Do you have a dyno sheet? I couldnt find one of yours in the dyno thread?

no i didn't want to fab up a massive 4" intake pipe, I managed to squeeze my standard one (with metal insert) over the smaller mouth.

dyno sheet is a few weeks away

ah yeah fair enough. its also quite a few extra dollars!

If you want the anti surge compressor housing your prob better off getting the 3076 as that comes with one for no extra dollars.

Keen to see the dyno sheet!

[Simon-S14]

much love for the anti surge housing... i have 4 inch hardpipe straight to Air filter (afm is on other side of pipework) and the spooling sound is insane! greatest sound on earth hahaha

[Harey]

Ah yeah didnt think about that. Once you have a 4" intake, the 3" afm will become a restriction and also annoying changing diameters if you did leave it there.

What options are there to remain with a 3" intake. I know simon you will recommend the 4" intake but think about it from a stealth on the street point of view. Is it possible to get an anti surge housing with a 3" intake on a GT30?

I've got an rb20 turbo highflowed by GCG on my rb25, makes full boost almost the same as a standard turbo but it pulls very hard even on 12psi around 200rwkw. Is currently being tuned with gtr injectors and all that jazz, hoping to see 240kw with almost standard response and spool times. For a street car it is all about response.

Only thing I don't like about the turbo is the service from gcg, if anything goes wrong you will be blamed for it and have to fork out for the bill.

I dont understand, how is that related to "R33 Gts-t Turbo Recommendation, most responsive for 275rwkw"
