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.

A twin charged setup is a nice balance, because you get boost right from the get go from the supercharger, which will carry you into the turbocharger's boost. You'll still have parastic draw in high rpm from the supercharger, and it is difficult to work out a proper method of plumbing the two units together.

Ultimately it is probably best left with a supercharger/pulley (if you can even find the sc12 pulley) for a modest DD, because your power is down low.

Personally, I would toss the supercharger and turbo it. If you don't go over the top with a monster turbo you'll be able to hit full spool in the 3-4K RPM range and make plenty of power.
