need help with planning a build.

[2g99]

ok i have had my 99gsx for about almost 2 years now. and i am still trying to find out everything the previous owner did to it. i know that it has:
-apexi turboback
-apexi safc-2
-rc racing 550 injectors
-ngk spark plug/wires
-im not sure but im guessing that it has a fuel pump also, my guess is walbro 255.
thats all i know of that the previous owner did to the car, im still a new to the dsm thing so i cant really find everything and no one around were i live is big into the dsms.
ive installed:
-Greddy type S bov

ok so my goal with the GSX is to be somewhere around 400ish awhp on pump and 500ish awhp on race fuel, but im not sure whate parts i will need and where to get them from.

if anyone can help me with a list/pics/vid with detail of what to do and get i would be very thankfull

thank you

i would check first and and see if you did have a wally. otherwise if you end up not having a wally and upgrade to bigger turbo. you are not gonna have fuel to support it.

I would suggest, better tuning agent. afc is not gonna cut it at that power level but you could get away with it.

Sounds like you need to do some more reading. There are many builds out there with similar goals. Also, is this a DD or weekend track car? Drag or autocross?

I'd go with a 2.3L stroker and a HX-35 with all the supporting mods.

yes it will be DD

is there any easyier way to check if i have a wally instead of pulling it out of the tank?

This ^ is perfect for what you're looking for. Work on getting the underlined before you go ahead and slap a HX-35 on there.

And seriously, get rid of the SAFC. If your wanting that much power you might get away with it with a SAFC, but your car will run SO much better and you'll have much more access to different aspects of the ECU. A SAFC is a BANDAID
