S13grl. I'm not dropping in an old motor. I am building my motor up with forged internals, balanced, ported and polished head, 3 angle valve job, port matching everything, bored cylinders and plate honing it. The slap everything together with ARP bolts and it should be good. If anyone dissagrees or has suggestions while I'm spending money, let me know.
Thanks DriftFreaq for reiterating what I have typed. I DO NOT RUN, AND DIDN'T INTEND TO RUN 17 PSI.
Ace - I don't think that fuel management would have helped anything. It was a boost-check. I was dicking with my wastegate cuz my damn revhard manifold spits out bolts, which frys gaskets, and makes me not boost at all. I had like 3 people in there, and one shut the hood. I figured he would realize that the barb fitting on the wastegate needed to have the vaccum line that was laying next to it hooked up. We went out, and it ran at 4 psi, then jumped to 17. I let off, the automatic shifted, and the BOV vented into the atmosphere, which I don't think helped my lean situation, and then pistons started blowing apart.
Ehh... what can you do though?
