I own a 91 civic sedan. I was wondering if the stock d15, first of all, can be turboed and second of all, if it can, what is a safe pressure to boost at?

1. Anything can be turboed, its just a matter of how much time, effort, and money will it require.

2. Boost pressure doesn't really mean anything, it depends on the size of the turbo you're running. I have a T3T4E 60 .63ar for my GSR and on 11psi it should make a little over 300whp, but that same pressure on something like a T25 would make maybe 220whp.

You have a lot to everything about turbos you can find.

yeah i meant on stock internals becuase i dont have loads of money, and i know that anything can be turboed

do a compression and leakdown test to see what kind of shape your engine is in......generally turbo d's don't push more than 220whp daily on stock internals......

the d15 are extremly weak the rods are the size of a sharpie. d15 usuallly grenade at about 150hp while the d16 can withstand about 200hp. i would just pick up an a6 and boost it

your best bet is getting the A6 or even a D16z6/Y8 and boosting it......if you have any more questions, just PM me or post them on here
