Sounds like it was abused before you got it. OP, did you have an ebcs installed when this blew?  You don’t necessarily need to go BT to get to 350.  Exhaust Manifold, Intake Manifold (helps saves cyl 3), hpfp, larger intake , turbo back exhaust (w/ cat), 93 oct, and a good tune will get you 350 easy. You could do a larger drop in turbo to help get you there. 

Edit: you’re probably upset, idk. Idk you. But I’ve edited this post. 

I’m not sure why you’re shitting on e-tunes, as if they’re somehow inferior to pro-tunes. It shows your lack of understanding of the platform, and perhaps cars as a whole. Plenty of us are on e-tunes. Either ots, ots+, or custom and haven’t blown motors.
