4a-ge(20 valve)silvertop swap Options

[Dr_Tweak]

Yeah it's true, I've done quite a few silvertop swaps, just finished one yesterday and took it for a ride. It's an auto and I was comparing it against my '94 Celica ST auto. There's definetly a lack of torque at the bottom end of the range, but once you're past 3000 rpm it's no comparison. When you first step on the gas from a total stop, 0-20 is like, hmmm, Where's The Torque??? But then you get past 20mph and it just screams up past 60 and you'll like, wooooaaaaahhhh.....

I would REALLY like to do the silvertop head on my 1.8L block, but it looks like a SEROUS pain in the ass.

Not worth it If you're doing all that trouble, go for a 3SGTE.

Heytalktoryan, you can use the stock ST tranny, you just need a flywheel from a regular 4AGE and then it will fit. You're going to want a full engine set (engine, ecu, wiring harness, sensors and ignition) at the very least, if you're doing it yourself then I'd say yeah, get a clip.

The only thing u need to replace to fit that motor in you ST is to replace the old motor mounts on the 7A and put it all on the 4A. From there its drag, and drop.

You could put the 4age head on your 7afe block and have the best of both worlds. Probably as powerful as you can get with a natrually aspired 1.8L

I'm not sure about that, the 2ZZ-GE, a 1.8, puts out 180 HP, the "magic" 100HP/liter. But a 7A-GE is definately more powerful, but in no way is it a bolt on job. Nik is doing a 7A-GTE.
