I am looking for at a new rotating assembly, I plan on going FI. Which cc size is best for FI. 6.5,9,11cc? Any help would be great. Thanks

you want the lowest compression ratio; around 8.5 to 9:1. so whatever dish size produces that with your setup. not sure exactly how to calculate this.

Not trying to be rude or start any crap...But it's probably best to just leave the specifics up to the engine builder. If you have to ask on a web forum for this kinda info, your clearly over your head. This is definately not a decision thatis on the scale of "which intake is better".For the sake of having your car be put together right and last for as long as you wanna run it, I would just let the engine builder tell ya what to order.

And again, this is really not meant as a flame or an insult. I've just seen too many cars go together only to blow up a week later simply because someone listened to his buddy or "some dude I know told me to use a..." rather thanlet the professional make the decision.

But seriously, I am with GT Bob on this one, find a reputable builder in your area, talk to him/her about your goals, and go with what they tell ya.
