i swapping out my jdm b18b for a d15b7 turbo.. here is the problem.. confused about what turbo setup i should go.. i bought a s15 t28 turbo and stock downpipe and oil kit and boost gauge..

how do i tap my oil pan and intercooler piping in confusing.. can i jus buy a intercooler piping kit on ebay and would it bolt right up??

what is the max boost can i push on the t28.. how much psi can a stock DX hold... is there any modify have i to do to my crx to put the turbo in?
