7a fe to 5s fe., has it been done? need input. Options

[pipwud]

I'm goin to try and make it happen.

I have been doing a complete rebuild on a 94 celica for over a year now. I put in a fresh 7a Fe engine but have a 5s Fe sitting around my garage. I was looking into boring it out and replacing the 7a Fe. I've also been tryin to look into an awd transmission that bolts up to the 5s Fe, if one exists.

To be honest, I don't k ow what I'm getting into.
New to 6gc. Been reading a lot. Did me good.

Plan on posting pictures of where I've gotten so far. in the process of wiring power doors in place of my manual I had previously. Any input on that would be much appreciated.

And anyone around phx, az?

The same AWD trans that the 3S-GTE uses (E154F) will bolt up to the 5S but it takes a whole lot more than just the transmission to make your car AWD. It's pretty pointless with the 5S, in my opinion.

To go from an A series engine to an S series takes a little bit of work but is very doable. Most people would say it isn't worth the effort to go from a 7A to a 5S, but that's because most of the time when someone asks, they still have to buy a 5S. In your case, since you already have the 5S, I say go for it. I've had both and the 5S is simply more powerful all around. It's worth it if you can do it under $500 or so, and keep in mind that you'll need new axles, shift cables, motor mount, full exhaust, and a few other things for that price.
