I am about to jump into the mod game for the first time.....just trying to read and learn.
What is the expectation we can squeeze out of the 235 and still just roll up to the pump, no race gas, meth, mix etc
Not trying to be a tool....just thinking out loud

The biggest limiting factor is the turbo. It's tiny. Throw whatever you want at a current N55 car, and the upper limit on the stock turbo is barely over 400 RWHP.
I don't recall the M3/4s turbo's specs, but I'll guess they are each either very slightly smaller than the N55's single turbo or roughly the same size. Companies have barely scratched the surface of tuning them and with few mods they are in the mid to upper-500 RWHP range.
