NTC3 pull start to non-pull question

I am replacing the stock motor on my RTR NTC3 with an RB Concept V12 rear exhaust motor. I went to the LHS today to get a non-pull flywheel. Its much smaller in diameter than the current one on the car. Will I need shorter motor mounts so the starter box will reach the smaller flywheel? Thanks for any help!

Here's what you'll need for a complete conversion:

engine mounts.
flywheel.
header.
pipe.
exhaust mount.

so the answer is yes. you can try without engine mounts but it will probably rub on the chassis

Default NTC3 pull start to non-pull question

SeventyGTX;

There are 2 different options when changing to a Non-Pullstart Engine.

1) If you are going from a side to a rear exhaust engine, obviously at the very least the exhaust header will have to be changed.

2) New Motor mounts and Flywheel are NOT necessary. You can use the ones off the pullstart engine and they will fit just fine.

The advantage to changing them is a lower center of gravity and a quicker reving engine form the smaller diameter flywheel used.

3) Be sure to buy an engine that has a output shaft to match the type of clutch you plan on running.

Most RTR Cars come with a standard shaft engine (*note: that most Associated kits require the use of a short shaft engine when the standard clutch is used*).

While most full race kits come with the parts for an SG shaft engine and centax type clutch.

hope this helps,

Thanks for all the help! Pops, this car has had a two speed in, so its set up for the pilot shaft. Can't wait to get the RB installed and broke in!
