hey, im pretty new with boost so you all please cut me some slack here. I'm about to buy my friends greddy 18g turbo kit with an upgraded intercooler and 440cc injectors i believe. it also has a 3 inch downpipe. my engine setup is a b16 ls/vtec with for the most part stock internals. from what i understand this kit has an internal wastegate which will restrict the amount of power i can put out. Can anyone tell me what more i would need to make this run if anything and about how much psi i should run and about how much power i should be looking for. Also hes selling it to me for 1500, thats a good deal, right?
