pass on venom injectors...they're terrible.question is not how much boost you want to run but how much hp you want to make.

i want about 4-500 between there, mostly like 4-450whp, i also am looking for a turbo that i can bolt to stock location that can handle like 18-20 psi of boost, anyway i can get a rebuild kit for my stock rb20 turbo with a steel exhaust wheel so it can hold 18psi, let me know thanks

why are you so set on a boost number?

worry about power, not the psi it takes to get there.

if you want quick spool and virtually no lag. go with a garret gt28rs. aka disco potato. people put down some real power with these. might put a hole in your wallet though

lol, you have no idea how much power 400whp is in an s chassis car much less a s13.power and response do not go hand in hand, one or the other.

Probably a lot of searching would be the best ...

Your power goal are going to cost you tons of cash and time

Common aftermarket sizes are 550's and 680s..

from what i've been told/read 550's will get you to about 400whp at 80% duty cycle..

680's will support near 500whp at 80% duty cycle...

and 18psi doesn't make a difference... you can make 400 whp on 14psi on some turbos and 200whp at 14psi on others.. so when referencing psi for an injector upgrade it's nonsense.

Just get 550's and find someone to make you a solid rom tune..

I'm running SARD 550's on my RB20. DIrect plug in... high impedance, blah blah blah. They are @ $100-140 an injector though depending on where you find them ... blah blah blah

ps... I just shi*t myself in the pants area.
