    I have a front mount intercooler, duel air pods, 2 3/4 dual exhaust system, new recon 5 speed manual, boost controller 11psi, dyno tuned.... will 550cc fuel injectors, ecu chip and 13 psi make it ??? currently 220rwkw South Aussie

    No.

    You're gonna need 17-18 psi to have a hope

    Dual Intake
    Dumps/Catpipes(testpipes)/Exhaust Dual 2.5" or 3"
    ECU remap
    Boost controller
    Intercoolers
    Lightweight crank pulley
    Lightweight flywheel
    Water injection

    There you go mate :)

    Sounds like you already have a fair few bolt on's which is a good start. However 300kw is very very hard on stock turbo's. I dont believe anyone in Aus has done it, I think the top was ZX2NV with 272kw before his engine died. Has been done in america though. Could be wrong though.

    You will need to go far beyond what you have though, and far beyond 13psi. At a minimum you will need a healthy engine, healthy turbos, intercooler upgrade, injectors, intake, full exhaust (dump/test pipes aswell as cat back), clutch, lightweight flywheel/udp, 1-piece driveshaft, good dyno tune, 17+ psi, upgraded cooling system, and a big healthy shot of NOS. I wont go into port/polishing etc because if you're willing to do that you may aswell upgrade your turbo's

    whats the stock turbo max psi i was told its 14 psi?

    I was wrong

    ZX2NV reached 300.6rwkw before his engine died.

    The stock turbos become pretty useless if boosted above 18psi.

    what are the best turbo's from 300rwkw to 450rwkw?

    i was told upto 600bhp was ok for stock internals is this true? If so what power output is possible for decent internals up to 5Gs worth of pistonns rings rods springs valves ect

    24 psi is the highest I've seen that I remember

    As for better priced performance, DIY.

    Plenty of information around here if you SEARCH!!!

    Huh?

    I think you may find that figure was attained using NOS shots.

    AndyMac Better than you

    You'll need the fuel injectors, dump pipes, something to alter AFR's (fuel cut defender or apexi S-AFC or similar) and you'll need to push those turbo's past 18-20psi. Even then your engine needs to be in top nick and your probably going to need water injection to cool the charge down. Stock turbo's break the choke line with a good intercooler at 18psi and you just create heat.

    He estimated the .6? :rolleyes: I could be wrong but i think he actually scored those figures.

    AndyMac Better than you

    With a good IC and dump pipes I'd say the max would be low-mid 20's. Stock turbo's run out at high teens tho as far as efficiency. There is no point pushing them further unless your using water injection to cool the temps.

    Figure was taken from the dyno list

    But I think chili was correct about the NOS shots. I think it may have been 272kw without the happy gas.. 300 with.

    In other words to answer the original question... it takes ALOT to get there on stockies... just upgrade.

    As Andy said, Injectors would require upgrading.
    Even if it was possible, you'd be so close to the max threashold, it would never be safe.

    ZX2NV Z Racing Evolution

    Yep to clarify 275.6 rwkw with race fuel and power FC stock engine/turbos

    Dyno proven 300.6 rwkw with a 100 shot of spray with stock ECU and unichip (big hole in map)

    Estimated 326 ish rwkw running 75 shot with power fc and race fuel.

    And to clarify further the engine is still okay apart from piston 6 which is at around 80psi due to a lean out caused by a worn stock fuel pump. The spray didnt kill her the shitty old pump did :mad: :mad: still ran a 1 min 10 at Wakefield with low comp in 6
