That does look really nice, better looking than my mates one (don't tell him i said that!
Not to sure on the Compression figures just know that at around 40k my mate had rebuild No1 (although that was due to overheating as Rad cooling fans that stopped working).
Then at 50k came rebuild No.2 when summink went wrong with his reconditioned turbos and scored-up the Rotor housings, there was a rebuild No.3 at some point but i can't remember why that was all i know is his car did the rounds with the handful of Rotory Specialists out there all of which seemed to slag off the other saying the other didn't know enough about Rotorys.
If there was a concise, decent enough manual on RX7 engine specs and rebuilds i might actually consider it myself... having said that 15mpg for a stock car!!!
My car runs 1/4miles in the 12's and i'm pretty sure mpg isn't as bad as that, whats the fuel economy like on a modifed RX7!!??
