The one that comes on the SP model, 33.

okay great, thats good to know. do the 33 carbs make a great performance difference or would it be just as good to tune up your standard carbs with a ram air intake system on it. thanks again Joe.

Depends what you want from it? fcr's give more balls out power but cv's are easier to use and smoother unless you're running a TPS and programmable ignition
