I have already started to collect parts for my first 4 port engine attempt.

Basis is an S4 13BT irons (front, middle, rear)
S4 NA housings (de-sleeved)
S5 9.7:1 rotors.
Rx8 eccentric shaft

porting to be determined.

Obviously everything will need rebalanced. My biggest problem is i live at around 5500ft and its get much higher very fast around here (up to 14,000ft...., 7500ft average in mountains). So power levels for me will be about 25% lower than they would at sea level.
