 any known mods to 4A-C

I have a 1984 Toyota Tercel 4WD (like a 4WD corolla). They come with a 3A-C standard which had been upgrade to a 4A-C before I got it. Since the motor was in pretty good nick and the problems changing to EFI (not as easy as your standard AE-86 to 4A-GZE mod, gear box etc) I kept the 4A-c. I have since fitted at 32/36 holley, custom built extractors and a 2inch exhaust with a lukey muffler.
I was thinking about buying a second hand supercharger, mounting it where the aircon compressor used to go, 2.5inch pipe into the carby and run a cheap pod filter as a cheap experiment into supercharging a carby engine.
Any other mods that anyone else has done to the 4A-C, like how far can it be bored? and will porting and polishing do anything? or is it a simple fact that anyone who has/had a 4A-C has/wants to put a 4A-G variant into there car because the 4A-c is just crap.
Thanks

sounds like you want to spend a crap load of money on a shitty engine. surely you would be able to fit a GZE more cheaply than doin all that work to a carbied 4ac??
can u dump the fwd section and just run rwd?

I've never heard of anyone putting a supercharger on a 4AC, my guess is you're giving the GE a miss due to it's lack of torque down low, which is fair enough for a Tercel.
But hey, anythings possible, but either way (S/C 4AC or 4AGZE) you might find your drivetrain the weak link..
You could always just do all the usual mods to the 4AC, which it responds well to ,if you do a search on the forums you should find some previous threads on 4AC mods. Most people go the 4AGE route because of the manifold design on the 4ACs which is a limitation on how far you can take the engine.. and it really is a much better engine, depending on your intended application of course.

Im not sure you can use the GZE or GE for that matter in the Tercel, I think theres a unique notch in their 4AC block to allow for the Tercels funny mount gearbox which the other G's dont have, I though I heard???? maybe?? that some 20V's may have this notch too but not 100% sure
