i bout bbk's 85mm intake and was wondering if i need to buy an 85mm throttle body. i know the stock one will bolt up but how much power am i losing by keeping stock?

If you put the stock on then it will only be a 78MM intake. I would say a good 5-10HP. Thats what BBK claims their 80MM TB gives you......

ok well i have found a 85mm intake for $180 didnt know if it was worth the money and if i would buy one wouldnt i have to put an 85mm maf and different smooth bellows?

nope, you can use the same maf and bellows. i have a FAST 92/92 set-up and i still use stock maf and slp bellows. works just fine.
