    Alright first of all I have a 99 GSX and i bought it in december of 2009. When i purchased it it was close to being stock other then exhaust, downpipe, intake, and coilovers. Im having a little trouble choosing which route i wanna go with the small build. Im hoping for at LEAST 300 AWHP but keep it reliable as it will be an occasional driven vehicle other then my honda.

    I currently have a small 16g on there and thinking on upgrading to an 18g. and all the fuel mods, tuning etc and all to go with it. Im thinking on running 20 psi on either of the turbo that i decide to go with.

    Current mods on the car
    FP manifold
    Small 16g (ported FP turbine housing)
    ported o2 housing
    HKS bov
    HKS carbon exhaust
    Megan racing downpipe
    AMS boost controller
    Punishment racing UICP
    Godspeed FMIC

    Things on the list to get
    Fuel pump, 560cc injectors
    Tactrix 2.0 cable
    272 cams
    and a few other things i cant think of atm

    So if you guys could help me out and give me your personal opinions i would greatly appreciate it. I would like more help on the lines of "Would it be safe to run 20 psi on an 18g on stock block?" The car is very well maintained i bought it with 87k miles girl driven before me. Compression is all above 150 all 4 cylinders.

    Heres a pic of the car i thought i would share
    (looks a little different now that it has a CF hood) [​IMG]

    There is zero reason why you couldn't make 300 hp off your current setup. You will probably need more injector and deffinatly a 255 fuel pump but other than that there is no reason you couldn't be a chunk over 300 now.

    As for the 18g, I haven't seen one in a very long time so if you find one, and don't use it, let me know and I'll buy it for safe keeping.

    +1 what Will said. For 300awhp, you don’t need a bigger turbo. Fuel pump w rewire, bigger injectors and a tune. Can’t remember when mine started slipping but I think even the stock clutch might still be good for that power level.

    nice car!!

    Are you friend with the guy that’s selling his teal 2g (on YT)?

    From what I seen you should see 300+ on your current set up. I would put that 20g money twords a new pump(with rewire), injectors, wideband, and link. Could even do evo 9 pump and injectors, thats the route I'm going.

    You should be able to make 300 with that turbo. I wouldn't hesitate to push that stock motor. The last stock motor 7 bolt i tuned had just hks 272s and arps. That car did 449whp at 30psi on hx35.

    You might want to reconsider 560cc. I don’t have my fueling sheets in front of me, but off the top of my head the 560cc will run 100% duty cycle around 370 crank hp, and you want 300awhp...

    Ditch the FP manifold in favor of a ported 2G or Evo III manifold...if the Small 16G feels too "small" you can always go for the Evo III 16G instead. An 18G (in OEM cast form) has absolutely nothing to offer over an Evo III 16G at 20psi except more lag. I'd suggest injectors that are more than just 20% bigger than stock as well.
