Hey guys I got an NA ST 7afe n i was just wondring about advancing my timing. I know that you can gain some hp in the wheels, but is it good for the car? Also, how exactly can u advance your timing? Can a local shop do it for you? Does fuel octane have a minimum for maximum power? Thanks in advance! haha

the how-to on the internet for the 5th gen 5sfe works just fine to use for the 7afe, yes you need to bump up your octane.

no need to have a shop do it. you just need a $50 timing light (or borrow a friend's), and a 12mm socket with wratchet. if you don't have that, you could probably do it with a 12mm wrench. you just need to loosen one bolt, spin the distributor, and tighten the bolt back up.

bingo, with an intake or just a derestricted airbox 5deg of timing really added some smooth power to the engine. all the way from off idle and it faded just around 5000 rpm. the header killed the fade and moved the power to the midrange.

I ran it on 91 octane no problem, then I advanced to 18 on 91 octane still with no problems, then I went back to 15 but used 89 octane, again with no problems. -------------------- 94 GT - Sold -------- 69 Pontiac Lemans - Sold 88 Alltrac - Sold ---- 04 WRX - Sold 00 GT-S - Sold ------ 91 Miata - project/drift car 95 GT - Sold -------- 96 GT - New Daily Drive |
