Which Street port designs yields the best results? My tuner has the mazdatrix streetport measurements. Which street port do you recommend? Also have some puerto rican street port designs.

does this street porting affects my air conditiong? WOuld a more aggresive street port affect my stock twin performance? would the turbos choke with the excess air flow of a aggresive port or bridge port? would this porting affect my reliability?

i am between a mazdatrix street port or a loquito killer (puerto rico) port. any inputs?

no, it wont affect a/c.

i wouldnt run a bridgeport with stock twin turbos.

no, it won't affect reliability.

as far as the porting template, i can't imagine anyone on this site knows anything about the loquito killer port, so they can't really help you with your decision

Personally, I like the porting templates from www.pineappleracing.com

While on this subject, I've got a spare engine I'm playing with. So far I've given it a half bridge and a race exhaust port and will be tossing on a set of non-seq twins. What should I expect to see at 12-14 psi? I know stock twins are not ideal, but hell I'm doing this for nearly free so I can't complain.

How did those non-seq twins work for you on that half-bridge?
