well i heard that the ct4s can hook up an 21. motor with the right modifications, but is there any motors which is 12. size that could be fitted to the ct4s.
the races in sydney here only except touring cars which have a .12 motor. so has anyone hooked up an .12 motor to their ct4s and what modfication should be done to do so.
thx

The Team Orion WASP .12 is a great fit

any .12 size motor should fit. Team Orions, Collarris, OSs ect...

Timmahh

but dont they requie differnt clutch things and gears or do they use the same same set up with the ct4s such as the flywheel, cluth shoes and clutch

all the stock clutch shoes and engine mounts will work just fine...
notch

hey would an OS TR R Spec .12 3 port engine fit the ct4s, any clues

yeah- make sure you get the slide carb though

yep as notch said. for sanctioned racing, you MUST USE a .12 motor. which is why you wont find a CEN NX-15 on the Team CEN Drivers cars, they are not ROAR Legal. ANY Surface .12 motor should work and mount without issue as long as its a slide carb.
