4age silver top or 4agze?, serious about it Options

[Stambo]

I've been thinking about getting a different engine but not sure. Don't just say 3s swap and be done with it. I like the 4a series because they are such a legendary motor and free reving.

I'm going to be rebuilding an engine in my college mechanic course and i figured why rebuild a 350 when i can rebuild the engine that i actually will use in my car. Since either engine isn't to expensive, i would have money for some upgraded internals. I'm really only hoping for around 170-200whp.

My main question is. Which engine do you guys think would be better for autox? Supercharged would be sweet because all of the torque is right there. But, the silver top would be sweet because of the high revs it can take. I have the money but i really can't decide. I've heard the silvertop is a great for autox and the 4agze is great for street use.

the stock ECU can handle turbo pretty good, you need a piggy back to control the bigger injectors, the better piggy back / EMS you have the better the tuning and thus more and safer power.


the best way would be to install the turbo before the engine goes in, so you have to drop it only once, but if it has to be done in stages, leave it stock and work the bugs out, then pull it out and install the turbo. no need to waste money on a pulley.
a pulley would get you close / to 200 whp which is still consider slow for the weight of a celica. This is coming from a guy with a 70 hp 7afe automatic.

BTW, you would want to use a e58 tranny from a toyota Levin, it comes with LSD and it has long gears which are great for turbo.
