change the ecu to a stand alone ecu, or at the very least a piggyback. you will gain quiet a good gain in average power everywhere and the car should feel like a brand new car once tuned. airflow makes more power so to make power, youll need more airflow, which means a larger turbo.

with a larger turbo the likely suspects follow;

injectors

airflow meter

clutch

tyres

suspension work

turbo itself

fuel pump

cold air intake

boost means nothing and is irrelvant. if you run 300psi or 3psi it means nothing, the airflow in turn makes power. pressure rating on a given compressor will ultimately decide how much airflow you dial in, and how much power. the rb25 turbo upgrade thread covers most of the common turbocharger ugprades. the guide munna has written covers most the common questions and combinations again. all the information is there and has been covered, you just aren't looking for it

At the very least you will need a bigger fuel pump and turbo then a unichip.And before I get roasted by the all or nothing brigade you did say "the next step".I sometimes look back on that combination from Croydon Motorsport as my favourite,fantastic fuel consumption and smooth as silk.And yes I am more than happy with the awesome power I have now but With a higher interest in track work I wish I spent the money on huge brakes,light weight wheels,sticky 255mm rear tyres,a front spoiler low enough to take the ears off an ant and a wing big enough to sun bake on.Oh, and those cute fluffy dice that jiggle when you hit bumps.They are so cute!

By the way, that combo with what you have as well should easily get 215rwkw.

sorry forgot to mention already got a 500cc walbro fuel pump what turbo do u recomend is there any difference between the series 1 and series 2 turbos i was thinking gcg highflow unless theres a cheper alternative only looking to run around 14 to 15 psi

[skylinecouple]

I have GCG hi-flow and running 15.5lb boost and making 225rwkw on pessimistic dyno.I do have trouble getting power to the ground on slower corners.

sounds good mate what other mods do you have

is there any other cheaper alternative?

[skylinecouple]

GCG hi-flow,fm-intercooler,hi-flowed injectors,PFC,k&n panel filter and bosch 910 fuel pump.Oh, and z32afm.

All new suspension.

I can honestly say that changing the suspension has given me the biggest woody.The ride is firm but soaks up bumps nicely.My corner speed is incredibly faster now than when it had the rock hard suspension.
