stock for stock, mod for mod or what???
i have a GTUs rx7 and its as fast as a bone stock T2 rx7.. but its slow as balls compared to a stock MK3 turbo.
the most ive seen pulled out of a non-built T2 is like mid 300's. beyond that, i find that most people typically have built motors.
a properly supported MK3 with a 60-1 upgrade CT will more than likely out run a T2 that is equally modded w/ upgraded turbo.
also, T2's are only about 400 lbs lighter than a MK3... as in 3400lbs vs. 3800lbs, in full trim. T2's are the top of the line RX7 so they typically have ALL the trimmings and luxuries that base models do not. so 300rwhp rx7 is most likely equally fast as a 350rwhp MK3.
