Go .64 housing. .82 will be alright for higher rpm but just lifeless any lower.

I personally will only get .48 housings because I like to be able to actually use my car. Just me...

What is the intended purpose of the motor? Track only? Some street?

Get the .64 one. You will regret getting the .82 really fast.

I have to agree with CakeEater.

Forget about the .82 housing as a friend of mine has a GT3076R with the .82 housing and its laggy as f***. Its a built motor aswell and spools around 5k with full boost (22psi) at 6k.

Thanks man yea its going to be a track/street car thanks for the input yea i had a t3/to4e ceramic ball bearing before with only a .48 AR and maxed her out at 300 wheel but was very fun to drive and the power started dropping off around 6,700 so im sure i will make power through 8 K what you guys think ?
