i understand this but like i said earlier the F22C from the AP2 S2000 also has a 90mm stroke. and it was awesome revving to 8000rpm. it does however have longer rods, and it's obviously not a flat four so doesn't have the clearance issues. when news of the FB20 first broke i did create a thread discussing whether some people would prefer the EJ over FB, specifically due to the borexstroke ratio.
