Hi there!
I'm sooo excited! I just read some info on the web about the last 4A-GE 20Valves built for some Corolla and thought this:

Is it possible swap a 4A-GE 20Valves (it doesn't matter if a Black or Silver top, the difference explained in the documents I read is not that much) into a Celica with the 6 speed manual gearbox made with some blacktop?

And secondly, is it possible and wise increase the displacement of the engine from 1.6l to 1.8l? If yes 'cause this doesn't give problems to the intake and this one is large enought to support 0.2l more, wich parts must be used? I mean, the only difference is the stroke so i need the 7A block or i can do that with something smaller?

The 7A-FE Celica is not that heavy...In opposition its strenght is the lightness...it is almost 300 kgs lighter than a BMW 316i E46 Coupe with 11 bhp more (105 for the BMW that is 1.895 cc)

I cant see why a 4A-GE CANT work on it...it will fit the car perfectly keeping the car light...300+ bhp on a FWD are too much...i'd like more 160 bhp ready to use everytime...and i dont like to go fast only between the corners...
