I plan to swap out the nitro Star T3.0 Engine (motor is low on compression and rather use money i would spend to rebuild towards a new stronger motor.The questions i have are, what o.s. motor would be easiest to swap it out with. Will i need a motor mount? and can i use the stock clutch and exhaust? if not i would really like everyone's help to put together a parts list so i can order everything all in one shot and be able to put it together one Saturday. Thanks in advance.
