GT2530>RB20 turbo?

[Skym]

It says HKS 25/40 for T3 / Skyline flange (bolt on) in link below and is rated to 350ps -

That's 30ps more than HKS 25/30 and roughly 100hp more than stock RB20 turbo.

yeah, bolt on ! Use stock manifold and even stock downpipe if you want to ! I might sell it to get a GT30 or something like this.

[m_melen]

your turbo will directly replace an rb20det turbo, no new manifold, no new downpipe needed?

[M13]

You mean get a t2 inlet welded on your compressor housing?

.........


GT3071 series came with T25/28 TURBINE inlet flange.

Stock is T3.



Inlet for compressor was 4"

From what I understand the HKS 25/40 turbo is bolt on to stock log / cast exhaust manifold with T3 flange and uses stock dumppipe or optional HKS split dumppipe.

Max might be able to take a photo to show you that it's bolt on.

[m_melen]

whoaz, if it's bolt on that'd rock! are oil/coolant lines swap-able between r33 and r32 GTSTs?

ATP turbo along with many others sell a T3-flanged GT3071R

Damn, mine was T25/28 and had to get my exhaust manifold (tubular) to be modified for that.


At least I got the turbo at a hell of a price :biggrin:

hey guys, will a GT3071 be more laggy than it's worth on an rb20? i know it'll be more laggy than the smaller turbos, but what kind of spool time difference could i expect?
i will be running on upgraded injectors, maf, the works

I'll let you know.

[MaxGTST]

Like I told you, my friend has a HKS GT3037 on his RB20, and there's nothing before 4500 rpm.

[m_melen]

4500 rpm is a bit too high for my liking. i think i'll stick with something a little smaller than the 3071 then.
thanks max, i'll get back to you on price later tonight.
take a pic if you can, i'm curious about this split hks pipe

[Skym]

GTS-R (racing version with RB20DET) doesn't have much until 4800rpm.

As far as I know HKS GT3037 = Garrett GT3076R which not laggy on a RB25DET (full boost by 3500rpm) and capable of roughly 426hp (at engine) at around 1.1kgm. Also is bolt on to stock exhaust manifold with an internal wastegate option, falnge for custom dumppipe / frontpipe.
