So I was curious about when I swap the MR18 with a MR20 about switching over to ITB's. Knowing ITB are set up for upper rpm power and standalone (ems-4, squirt, m4) I need to know these things

1. What is the c/r of the mr20
2. Cam specs lift, duration, overlap, timing etc.(power range)
3. What is ecu tied into ie body control gauges etc.
4. Cast or forged internals.

Crap noticed that the stroke is bigger than the bore on the 2.0. Damn its a boat anchor too. Every time I think of something cool to do nissan screws it all up. MR18 peak power at 5500rpm MR20 peak power at 5100rpm therefore itbs would be less useful on the MR20
