has anyone done, or know how to do, a .21 or higher size engine conversion into the ct4s? or is there any other more powerful 15-18 size motors that would be appropriate...must be pull start too

there is a cen adjustable engine mount available that will allow a 21 to go in the funfactor, i think it may work for the ct4 too. pretty much any pullstart 21 should go in there, have a look around, just make sure u get the correct crankshaft, not sure what the ct4 uses tbh.

The ct4 uses a big block .15 motor so any big block motor should fit without any major modifications. Drivetrain reliability might be an issue though.

Just a quick question. Isn't 70mph fast enough?

i dont want it to go faster, i want it to get up to speed faster. the car is geared up so high, i never hit top speed. i want to get the comp drivetrain, and get a bigger motor to compensate for lost top end
