redline

what is the highest rpm you can hold the 46g3 engine at without hurting it and also does anybody know what the hightest rpm you can hold the 420a too? just curious witch motor can rev up higher cuz i heard you can hold this cars past the 7,000 mark.... but it probably doesnt make since too... thanks

I know someone who shifted at 9K
that wasn't a stock engine though, and it had a standalone

The Tranny doesn't like that though

4g63 - Factory says 7000, but these engines are good till 7400-7500 without any problems, from what ive seen, i wouldnt advise it, however i havent seen many problems of over reving.

420a. 0rpm you dont need to be reving one :-D
factory says 420a redlines at 6500...



so which one you think? i never hold mine past redline if i hold mine at anytime its about 6000 where i launch at.. onlytime mine goes past 7000 is right before i shift

i saw a mp3 video of a eclipse bouceing it off the limiter (7600) (4g63)
i also saw a eclipse shift at 9, and one had the tach buried at 9 in 5th :eek7: he hit 200mph on the dyno lol.. i normaly shift at 7 when i race lol other wise its 2-3 lol mabey 4

From what I can tell, stock for the 4g63 is 7500, but poeples tachs vary widely. It is common knowledge that a stock head can take 8500 rpm, which is already testing the limits of a stock trannys shifting ability. I have been over 10k rpm twice on a mishift (for several seconds) with no ill effects. My rev limiter is currently set at 8250, while I shift at 7500.

i don't usually like to take mine too far past 7000. But on the otherhand im a pussy and i don't want to do anything to bad to my car. One race isn't worth getting a new tranny. Or is it? hmmmm......

For most poeple, its not worth going past 7500 anyway. When I was on the stock T25, but somewhat modded, I dropped my shift points from 7k rpm to 6k rpm, except first which you should take to 7500, and went half a second faster in the quarter. The car has to be setup to take advantage of higher rpms, or it can actually slow you down ;)

I have been over 10k rpm twice on a mishift (for several seconds) with no ill effects.

wow lmao 10k?? holy shit!! lol i thought the engine would explode lol ima customize a engine to shift at 10k and still be makeing powere lol with a 6spd tranny (is dreaming) lmao

Well, i wish my car would make some power at 10k rpm, hehe. But if I wanted to shift at 10k, I would have kept my Rx7... Race motors in those cars go to 13k or so. lol

I still have the 14b turbo on my 91 gs....I heard that it doesnt make sense to rev up past 5500 rpm while driving, because the turbo and engine start to lose power after that...is this true?

No. The optimal shift points for a 14b car with stock cams will be 7500 (or as close as you can get without hitting the rev limit) and 7000 in the following gears. The 14b is a very capable turbo. Now, the stock 2g turbo, the T25, is another story. By dropping my shift points (2nd gear up) from 7k to 6k, I went half a second faster ;)
