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?

EDIT: You might as well get new dials which places 0-8000 revs inbetween where it would normally mark 0-6000, it would be cheaper and give the same effect as putting a 4age in place of a 5sfe. End of story?
