Re:how strong are d15's?

I didn't want to run 14 psi though...it was actually 1 bar.
Think the turbine housing was so small the thing kept on spooling when passing 5500 rpm's.(wastegate was set at 7 psi)
Small internal wastegate hole etc...
I raped it like I wanted to break it...actually i wanted to blow it up but it didn't....3rd gear and 4 gear 14 psi pulls are nice...sometime it hit limp mode at lika 7K rpm's lol...those were scary thought the motor blew a few times, but it didn't.
eventually I sold the car afterwards....without the turbo kit. A lady hit me from behind and I got my insurance money sold the car and bought an '89 EF si...just because parts for it are cheaper and more abundant and I'm still a college student...

i boosted my d15b2 w/14b@11psi with 329,000 kms running uberdata... lasted less than 3 months when it lost too much compression... i've been led to believe that shorter rod stroke is better at high rpms

ok everyone is throwing around psi as how much psi well lets look at in HP a d15 should and i say that loosely because i dont know the condition of your motor handle 200whp so go for that not how much psi.
