yeah the rb26 440cc are direct drop in.all you need for that is the rb26dett resistor so you don't fry your ecu...plenty of info on here bout it

im planing on selling my 440cc and resistor if your at all interested...

What are your HP goals?

The rb25 turbo has the same limit as your rb200 turbo, around 13psi. I believe any way, I think the S2's have ceramic exhaust wheels too.

I thought the rb25 turbo could make more power at the same boost level and net you close to 300 to wheels...
