well considering the 2530 is rated at around 320hp, and you can get your one hiflowed to 450hp i'm wondering why you would want to turn it into a 2530?? If you are just gonna get your one hiflowed anyway go all out, costs about the same anyway. If you want info on the hks turbos look here.

Difficult to directly compare the specs of those two units.

OE Nissan unit has larger comp + smaller turbine impeller vs the HKS

HKS unit has significantly different housings vs the stock Nissan stuff.

The result for both is fairly responsive units, but known frailty with the OE ceramic turbine if you boost it. I suspect that but for the frailty, a stock Neo RB25 unit would outflow a 2530 by a small margin.

There are a number of places that can do a high flow of OE turbo - and the bolt-up cost benefits are worth considering. Check the stickies for RB25 upgrades, and use your search function for a few ideas.

cheers.

no worries thanks, cos i wana get it rebuild with steel wheels and being realistic i only want to force around 16psi..

i was just kinda debating on which turbo would make more power / spool qwicker and in the end result in being the better option .. i would of thort the hks bigger intake would of made some difference?
