What engine mods next

JLarson

Dewla Design air guide; Race Intake upgrade from z1; Ported throttle bodies; Ported upper intake manifold; Ported lower intake manifold; Headers; Cams. Listed in order of difficulty.

Some general notes: You've already done the big stuff. Cut your losses now and go for the tune, and you'll have 90% of the gains for a reasonable price.

Remember that you'll lose most breather mods if you go for forced induction (especially with a turbo), so unless you buy them used, they won't be cost effective (race filters, dewla air guide, possibly headers.) Cams, ported upper, and ported lower will all synergize well with your eventual forced induction plans, so they may be a better choice - but you won't see a huge improvement through most of your power band.
