Hello, I'm new here & think this is the place to be asking the following questions!

I recently sold a 520bhp Evo6, and would like something different, a MK3. I know that sort of power from a MK3 standard engine is a tall ask, I don't want 6/8 cylinder engines.

I'd like to get a mk3 MR2, what 4 cylinder engine options are available to fit pretty simply in the MK3?
I would like around 350 bhp (@ fly) which must be reliable and quiet (for motorways), as a daily driver (although just a toy).
Any ECU considerations? The intercooler would be a roof mount (RS200 replica).

I have only just started learning about the MR2 so excuse my ignorance, there is a lot to take in (chassis codes, engine codes)!

Many thanks, Nads.
