Engine choices ??????
 

Hi from the uk ,have a kyosho mp7.5 at the mo with some mods ,,,running the std gxr 21 engine tinking about a upgrade soon thought about the gxr 28 st as fitted to the us sports 2 is it a good chioce or not or would you go for something else ???if so what im after some proper power:nod::nod::nod::nod:

Do you care about being class legal? If so... .21 is the limit.

I suggest the VSPEC. Great motor.

If your lookin at racing go with any of the .21 novarossi engines:nod::nod::nod:
I'm currently running a 21-5k and love it. I have the wrong pipe on mine but I tuned and ran my friends car with a dynamite 086 pipe set and I was pulling people down the straight and running 206*F :D
A .28 is too much power for a buggy and would cause unnecessary wear on your drive train.

I would go with the Vspec:)

might want to check out GRP .21 tuned promo kit comes with good pipe and gets good mileage and is fast. if money is a issue it is good motor pipe package . or can go with vspec they are about 249 on ebay for reg. one which is all you need. if money aint no thing for you get the best and most pro run bad a$$ speed motor its the pooh but pricey

Budget ?

Pull start or bump start ?

Bump start all the way, there is no option. What brands are readily availible to you?
