OK, folks, just bought this engine. Supposedly a Bruce Terrentine (of GA) rebuild from a few years ago- has not been run. It has side exhaust ports (unlike my turbo FDs), 3 of them-they are in the irons, so a 3 pipe exhaust header is required. The intake ports are 4 of them, middle iron with 2, 1 each on the others. The oil injector holes have been plugged (supposedly to use only premix). There is no ancillary parts-looks like it needs an ignition magnet sensor (no distributor type provisions), and all the FI apparatus as well as an FI type intake. I'm trying to guess the hp this engine could produce......any guesses? I'd like to build it up and run it, and knowing what intake and FI would fit would be a great help. I was told it may be an RX8 MSP Renesis I or II series engine build?

 

Yep, early Renesis engine. Automatic transmission cars have the upper ports on the front and rear filled in like yours.
2009 and later engines have 3 oil injector holes on each housing.

 

do you know if the FD parts fit the renesis engine-for example the mag pulley pickup, coils, intake, tb, etc? Or are they all 'different'. I'm looking for an on line rx8 parts book as well.......pretty familiar with the FD but not Renesis types.
So what was the stock hp rating on this early Renesis auto transmission engine? I know they had 2 versions of the engine with regard to hp output.

 

to my knowledge, none of the REW parts you mentioned fits the MSP. they are different.

if i recall, the automatic engine (the 4 port) was rated at 212 at the flywheel, where the 6 port was something like 232 to 238 depending on the year.
