[themadscientist]

Turbo is rated for it.http://www.hksusa.com/products/?id=704the stock long block will handle it so you will need better intercooling than stock and more fuel delivery.

Get some 440cc injectors300ZX Z32 MAFAn SAFC-II which carl hates, and will chime in on that.... but nothing serious is needed till your up past 320 anyways...Increase boostFMICFPRWideband And learn to freaking state a literate question instead of 12 year old innanetz lingo........ That will get you a lot of more friendly help points....

Or get a good chip tune, that's what I did and I don't even need to use my SAFC 2 anymore.

meh chipped ecu and injectors will do that...rb20 maf can read that much air.but z32 isnt too too hard to upgrade to, i mean ive got a program here for a hks 2530 w/440s and z32 maf...

[nissanman04]

the safc II won't be able to handle the 440s, it can only compensate up to 150% of the stock injector size. 400 is about as big as you can go.

[Kansei240sx]

My friend made over 300 rwhp on his RB20DET running an IHI RHC6 and 440cc supra injectors.

[Carl H]

yay to 0ver 80% duty cycles...

[oneruffryder42]

Kansei240sx- sorry about the 12 year old lingo. it was kinda late.

Carl H- wow how much for the chiped ecu???

here is the problem i got the hks gt2530 turbo with t2, not t3. is there any way i can still use this turbo. if not, what turbo can i use, ill just sell the 2530.

[Carl H]

Before I chipped my ecu my apex 2 was doing fine with my rb20 and the 460 rx7 injectors. I did 315 with the apex, fmic, t3t4e 57 trim and the 460 injectors.

yes fuel presure is set at 38 at idle.. using a honda b&m regulator and an inline fuel gauge. will get on the dyno again and see how the chipped ecu is doing.

Stay away from ebay turbos, and theres hardly any difference between those turbos they're both 16v. I'd never buy any of the **** that place has to offer.

BAM! Theres your 300+ right there!

[oneruffryder42]

besided the gt2530, what other turbo would be great for 300rwhp on the stock mani. thanks

[themadscientist]

VG30ET OEM.

[oneruffryder42]

VG30ET OEM.

what turbo is that????

[wawazat8402]

its the stock turbo from a turbo Z31 motor (i.e. VG30ET OEM).

[oneruffryder42]

any others. other then oem

[Yellow4g63]

The Good old 50trim T3/T4E. That will get you to 300hp easy.

[Sil240]

If I were you, I would send that turbo out to have the housing changed.

Or just sell it and then buy a T3/T4
