i give you two weeks till it grenades. you have no EMS, no major exhaust work, and youre running 16psi?
(attention)
TURN. IT. DOWN.
these engines have toothpick connecting rods that are good for maybe 250whp with bolt on everything. without? you can run about 8-9 psi on a FMIC.
small shopping list: front and rear motor mounts (or inserts), vacuum lines, vacuum distribution block, and a catless midpipe. you could probably do all that on about 250. after that, yeah start to PNP, intake/exhaust mani's, EMS, downpipe, blah blah blah.
