T25 turbo for the s12?

[s13eater]

i ran 221bhp on standard injectors with t25 at 18psi, i'am running 17psi at the moment on a t3/04e and have had it up to 24psi, the head bolts are still ok and are standard ones, ARP don't do uprated bolts for the ca18et although they do them for the ca18det, this is the only week link on my engine, if i had some uprated head bolts i would run about 28psi on my engine, at the end of the day, its mainly down to fueling and how good its been set up, although you do need uprated internals, the stock motor in good condition is good for around 265bhp.
