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?

    • I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.
    • Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.
    • Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them? 
    • I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.
    • Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
