Seeing as the boys are going to run 13" wheels, my thinking is the tyre circumference will be rather less than that of oem Celica tyres. 

This means revving the nuts off the Toyota engine at normal motorway speeds. Makes for nice acceleration but also increased petrol consumption and a lower top speed.

Or are you considering different gear and/or longer (taller?) final drive ratios? This has been on my mind for quite some time so I wonder what your thought on this is.
