how to support boost
Alright guys, this may sound dumb but I've searched high and low. I have a d15 in my crx, already did the mpfi swap with 310cc injectors. Slapped a turbo on and running 7psi. I'm new to the import scene. i know for a v8 you have to reinforce the bottom end to support the forced air but not sure what i have to do on these 4 bangers with only a peak of 160hp. So my questions are: if I'm running 8.5 compression stock, do I need lower compression pistons?; Do i need to sleeve the block?; Do I need double valve springs for higher revvs?; Head studs?; Forged crank? (keep in mind im only running 7psi) I've noticed a lot of yall running 7psi on a stock engine with no problems and only doing internal mods to run high boost.

Forged crank LMAO its not a chevy man.
PSI is irrelivant.

Sadly.
If your not running a bar youre a girl.
No sleeves
No pistons

14 PSI...
DSM450s will get you 300

hondas have forged cranks stock. i dont know off hand what the d15's have for compression but you are close enough.
untuned, you dont have 160whp. dyno tuned on 7psi 160whp is possible.
you can run 7psi with no issues on a 100% stock block. if you plan to leave it like that for a while then get it tuned.
