engine

hey im new to building custom models were are u guys buying your motors for them i have a couple models i wanna put blown motors in

Often, motors are included in the kits, but there are other places to buy them. Sakatsu, The Parts Box, Ross Gibson, and even myself offer engine kits. Try google to find what you're looking for. Any engines in particular?

Sometimes you have to buy another kit for the donor engine. Just like an engine swap on a 1:1 car.

Otherwise, some of the after market suppliers will make the parts.
You can get entire engines, or just the super-charger parts, and fit those on to the engine that came in the kit.
