Celica Forums General Discussion General Whats the Difference

hello again i have a friend that has a 7th gen Celica and he asked me a question what is the difference between the 1ZZ-FE and the 2ZZ-GE i went online and all i could find is the bore, stroke, and the head is that the only things that are different and does the GE head flow more air through it is that one of the reasons that it has more horse power

The 2ZZ has more air flow, higher compression, higher redline & valve lift.

ok thanks would it give someone an advantage if they put the GE head on their FE engine block and if they did that would they have to take the comp too correct

Not sure, but I do know that the GE is made of alluminum. You would also need to swap out ECU's, because an FE ECU will not function properly with the GE engine.
