hi all,

got a couple of nitro cars given to me in pretty bad shape, all dirty and a few parts missing, motors had shit in the throat of the carby. so i gave them a clean up and made one out of two, and she came up like a new one, i say they hadn't been used much. the engine cleaned up alright but had a fair bit of shit gone down the throat, so i brought a new one, here lies the problem, when i got the new one it doesn't look the same as the old one.

 the blue one is the old one, which has 3.5 on the side, and the black one is a 32r/abc/rs, both are Force Models Co engines. the notice difference is the 32 has a much large head then the 3.5 motor. 

have i read the sizes differently and got the wrong engine? or are they similar size capacity?

wil the new motor be to big for the car, or can i still use it?

all help appreciated, thanks in advance.
cheers scubee

Thanks guys.
So would the .32 be too bigger motor for the car? The car is a G.V. Rex X, four wheel drive off road buggy.
