Group,
This is what we are trying to do............This is junk O-540 crankcase with the "Vans" RV10 mount ring bolted to the top mount "Ears" and a RX8 Renesis front
cover and waterpump in proper position of the O-540 crankshaft shaft to see if the Mazda 13B / 20B will fit in the confines of the mount ring............The alternator
mount on top of the Renesis cover has been removed and alternator will have to be relocated............Hope the photo is small enough to send to the forum..........
Best

Kinda hard to assign them any credibility when within the 1st couple of minutes they either ignore (or aren't even aware of?) the fact that the Renesis has one of those 'small' exhaust ports on each plate. Of course, everything's a compromise, but I'll take the quieter, cooler exhaust, along with the 10-15 lbs less weight and an additional 20-30 HP over the best stock NA 13B. Obviously, the 13B can be pumped up a lot more with mods, but it's hardly fair to compare the engine to the twin turbo version of the 13B.
I really wish they'd kept the 3rd gen body & inserted the Renesis engine. If they had, I'd go looking for one as a daily driver.
