Hm a stroker would be way to complicated I would think and costly.

Keeping costs down, without stroking it what else could be done? (it is already a 3.2l engine guys (like I said guys in the s2000 crowd have a 2.0l and thats not holding them back).

So keeping the stock displacement, what else? Raising the stock compression with a thinner head gasket, and water/meth injection I think would help... Anything else?

I will be making a custom exhaust and intake, what do you think the best diameters are for them? (I think a single 3" intake and single 2.5" exhaust would be the best) What do you think?
