change radiator?
 

I read somwhere that rotary engines have a tendency to overheat when modified. is this true?should i consider changing my radiator before i get started with anything else or is my stock radiator ok? I have an 87' n/a any info would be greatly appreciated.

stock rad is fine for an NA, the only time u need to replace is when it leaks, then just buy an alumuin if u have the money.
