4A-GE ENGINE SWAP, Sick of the 7A-FE Options

[JoKeRkId613]

I love the reliabilty of the 7A-FE and all, but I want something faster. I'm hesitant about getting a 1.6L engine, but hey, it has VVT and 20 valves. I wanted to know what's better, the 20V Silvertop 4A-GE or the 20V Blacktop 4A-GE? Which one has more HP, other specs, etc. I know Xpander has the silvertop. I wanted to know if the blacktop will be as easy to swap.

Also, I wanted to know why nobody has done a 4A-GZE swap? If Xpander did the GE, what's so hard about doing the GZE? Isn't it the same thing with a supercharger attached to it.

So that's basically it, because I know putting a 3S-GTE would be too much work and money, so I'd rather stick to my "A" series engine.

I want to stick with my Automatic 7A-FE tranny as well. Will it bolt right up the the 20V 4A-GE? What are the specs on the silver and black tops? and why is the GZE so hard to do?

Thanks!
