anybody?

O.S 18tz if it fits (crankshaft)

A OS 18 CV-Rx has plenty of power.
You can still use your rotostart (take the pullstart off and put the rotostart backplate back).
It's available with a standard crankshaft.
If it replaces a T-15, then the only thing you need is a engine mount.

And the 18CV-Rx doesn't cost you an arm and a leg.....

if you want to hit the track legally, get the os .12tz Standard crank. it will require some other things also since its not pullstart. the fastest engine you can get for it is the 18tz. its pull start. that is the fastest .18 os has and for that matter the fastest engine you can put in that car. for a pipe, go with rd logics. the rtr 3 from rd logics. pm me with ur choice, i can give u more info.
