little story, my cars a kr monster too, well used to be. a aem meth injection kit is cheaper then a ic. and likely do more.

i have a l36 bottom end, gen 3 blower, diy ported heads, 1.95 rockers, and a fsic. i was running a 3.2 with all that, and like 14 degrees wot timing.

added a meth kit, got it to take 21ยบ wot and running a 2.8 kr free.

im willing to bet you could run a 3.0 with meth and more timing.
