Status: offline 		Yes, you could but by the time you modify all the rest of the car to work with that Engine you could buy a whole new Engine!
So Yes it can be done, but no I wouldnt do it, because you will have to change alot of things to make it fit and run correctly.
I hope that helps!

Status: offline 		they already make a engine mount and flywheel adapter for that engine to put it into the car. The only thing that i am worrying about is throttle linkage and buying a engine pullstart

Status: offline 		i know that they make a longer chassis conversion for the 4 stroke, but will there be enough room to put a .40fs in a tmaxx without the conversion??

Status: offline 		You just can bolt a "pull Start" on the back of the engine, the Carb set up and crank in that engine is not designed for a pull starter.

Plus the crank shaft is LOOOOOOOONG, to long you'd have to do some cutting and shimming just to get a flywheel on properly.

Better off trying to find a FS-40S-CX truck/buggy engine, then all you need is a standard 25 conversion I believe.
Don't forget the cooling Fan. Everyone that's run 4 strokes in a truck has had to fig a fan to keep the engine cool. The 4 strokes don't have big enough cooling fins and run hot without a fan.
Unforunatly that engne is discontinued, came in a pull start version too

lol. Better engines like how? 2 strokers=higher rpm which will=more spped that a lot of people like. 4strokers produce ALOT more low end torque(sp?). So there ya have thats why not to any people use 4strokes. And 4 strokes use a differnt kind of fuel.

Status: offline 		And actually I think gearing is the issue as far as speed is concerned
That FS-40S-CX 4 stroke will turn 20k tops(the fs40 maybe 14K before it starts floating valves)
a average .21 2 stroke will turn 35k(+or-) easy
you'll need to turn up the finial gear ratio at around 43% higher to achive the same top end speed. That's a big gearing change

Now if you put the FS-40S-CX in a buggy and ran the MT tires/wheels then you might get close to a decent speed, and can play with bigger clutch bells to get the idea finial drive ratio

I love 4 stroke in my planes, but I can't see going to the trouble foe a car or truck
