hi guys i was just wondering if any1 knows how far you can push the 1.8L (7AFE) ae102r past redline to get max speed outa 1st and 2nd???

or if not.. wheres the best place to change?

i believe at 6,400 it will hit the limiter

or 8,200 for me hehehe... 20v ftw!!!

why would you want to go past redline? Suggest you change before redline... even at 5600 will do. A squirt to that 5 grand now and again is ok... but sesh every day you'll get sick of it. Suggest you opt for bigger engine eh... like 20v or forced induction route.

Really depends on what the power curve is like for the engine, but no real point in going past redline.

4afe/7afe's wont really pull any harder at redline or beyond than they will at 5k, without spending up on the head and ecu tuning.

From memory the peak power is at about 5600rpm, really no point to stretch it to redline in around-town driving, considering that peak torque is around 2800rpm. At redline, the engine is really struggling to breathe so it's not worthwhile pushing it any further. On the other hand, chuck a C56 in there and make her breath a bit better with some extractors and head-work, and it'll love being revved that high - everyone underestimates the 7AFE, yet one of my mates (Davo on Twincam.org) has one that dyno's higher than a stock smallport 4AGE with just headwork, exhaust and an eManage, and with much better torque too
