os 18 tz
Could anybody tell me the different between an OS18tm engine and an OS18tz engine? I kno the 18tm is a direct fit in the REVO, is the 18tz alos a direct fit into the REVO? Also is it faster than the 18tm?

RE: os 18 tz
The tz has more power and higher rpm's but is not a direct drop in while the tm is a direct drop in. Either one still has more power than the 3.3 and the os is a way better motor.

RE: os 18 tz
I believe the tz is bump start only. I know the crankshafts are swappable though, so you can install a tm crankshaft in a tz and use roto or ez start. Correct me if I'm wrong, but I think you need to mod the throttle linkage to get the tz to work.
