Ok, bought a 93 corolla DX.. thought for sure it was a 4afe.. it's hard as hell to tell the difference between the 4afe and 7afe sometimes.. I guess I just have to take a peak at the ECU. The VIN says it's a 1.8L... however, checking the VIN both engines use an A as the 4th digit lol.
I got a 91 4afe for a 100 dollars.. was going to pick it up tomorrow.. 115K miles and a new timing belt. So now my question is... I know I can use the 4AFE but what would I need to change on the motor to run the 4AFE with the 7AFE ecu/harness so this can be as quick and simple of a swap as possible? The motor in the corolla has a hole in the block directly below the oil filter.. have no idea why.. didn't get to investigate yet. I stuck my fingers in though and I didn't feel a piston rod or anything strange.. lol. The ever so small amount of power difference between the 2 motors doesn't bother me, this is more about economy and reliability than power. -------------------- 87 4runner DLX 22re, 5spd, 4.30gr, 4" lift, 30" tires, HID w/ Projectors, 6spkr + sub, custom exhaust, 94 celica leather seats, SR5 gauge cluster and clinometer. Future engine swap... possibly a 2jzge.

they both use the same distributor when theyre from the same generation. between 92 and 93 is the split for the 4afe. both are called a 4afe but one is different from the other. 92 and earlier have a different head design and do not use an IAC motor, but use a waxstat to control idle speed and have a bypass valve for idle up.

Dude I'm not talking about an older 4afe to a newer 4afe.. i'm talking about a 4afe to a 7afe. -------------------- 87 4runner DLX 22re, 5spd, 4.30gr, 4" lift, 30" tires, HID w/ Projectors, 6spkr + sub, custom exhaust, 94 celica leather seats, SR5 gauge cluster and clinometer.
