12 psi in stock twins?
 

Hey guys I'm getting my car tuned Friday and I wanted soome input ...what do you think about 12 psi on stock twins for an fd I have the apexi power fc, fmic, race radiator ,greddy exhuast just wanted to get some opinions I believe I'm at 10 psi right now

You'll be fine at 12. If you're using the n3a1 twins then I would suggest keeping it at 10 but 12 will be fine. Just be ready to swap them out if you beat on them frequently.

Thanks for the info , I was wondering how long the stock turbos last because I believe mine are stock and I have 90k on my car , at what point should one looking for new turbos or going single ?

when it comes to mileage, its more what kind of miles those turbos saw. if there "easy" miles then its cool but if theyre abusive miles then..... you know. the decision to go single or stay twins is a rabbit hole of information factors but long story short, if you want a simpler engine bay and more linear power go single. if you like the response and low cost of the twins, then stay twins. i would say so long as your current twins arent smoking or leaking oil then run them until they do so. replacing them with the engine in the car sucks so i wouldnt bother with them unless it was necessary.
