auto ae92 sedan rev limit/fuel cut? - Toyota Nation Forum : Toyota Car and Truck Forums

I have an AE92 sedan (the slow one) with an auto trans and no tachometer.. does anyone know how far past redline the fuel cut is, and if I'm doing any damage to the engine by hitting it aside from excessive wear (I think it's a 4A-FE)? When I floor it, it usually shifts out of 1st at about 33mph (53kph) and 2nd at 63mph (101kph). If I use L and 2 on the shift lever, it cuts off fuel in 1st at 45mph (72kph) and 2nd at 75mph (121kph). I'm wondering what RPM those speeds correlate to.

The reason I want to know is because I have to drive on very steep and long hills and despite power dropping after it reaches peak, I still find I get more power revving higher past redline in the lower gear than in the next gear, and it's useful in emergencies as long as I'm not crashing pistons into valves or anything.

Thanks for any info.

well i have a 4a-F and its revs 6500 in 2nd gear and its does about 115kmp in 2nd gear. With no problem at all no valve bounce, missing nothing it just revs clean.

My bad its 130kpm in 2nd gear at 6500rpm

hmm, must be an auto.... that sounded WAY off to me for a minute there....

Flashmn · 08-05-2004, 12:31 PM

hmm, mines manual and it does about 120 on 2nd gear

TRDemon · 08-05-2004, 12:37 PM

Yes guys its an automatic and the figures are correct. and I have another engine headthat i have dubble valve springs installed so i would see how that will work out but if all goes well my machanic says he doesn't see why i can't rev at lease at 7000 rpm

120km/h with a manual is a little high there...... what are you revving at?

my smallport goes up to 70mph in 2nd gear (which is already ridiculously high) and that's at 7800rpm's with a c52

About 7k

C52 here too...

toyotaspeed90 · 08-05-2004, 04:56 PM

that's strange.... because the c50 and c52 mr2's can't even do 60mph in 2nd gear at 7500rpm's.... i'm curious if you have longer gears in your transmission

Flashmn · 08-05-2004, 11:32 PM

No they should be the same. Unless the Mr2 has the same tranny as the GTi corolla which would have a shorter final drive.
