I don't have to worry about buy a whole kit. My local hobby shop will order me the parts I need. So I just have to tell them the kit number and part number. So if I need an engine from say, a Taymia kit the can order the engine tree from Taymia Canada. So, anymore ideas? I would like an engine with a turbo or something that what the car would still be a muscle car. Is the 300zx a fwd car?
