this is slip, not la la the blitz riceboy.
from what rb25de owners have repeatedly said in the past, its a not too rewarding or good value experience in powering one up. You may be dissapointed in the end result.
on the other hand, i say build a cool rb30de with 11:1 compression, big cams, aftermarket plenum (subzero style), headwork exhaust and ecu tuned. but thats just me
love your work doxxi.
