Figured this is where to ask my question. So I'm about to purchase an Edelbrock Performer X IM with a Blox 66mm TB. My question is will this be alright with my set up that I have for the moment? Cause I've heard if you go to big with your TB you could lose power and I don't know what too big is.
My set up is stock B16 head with B18A1 block bored out to 84.5mm, Golden Eagle HD sleeves, Micro polished crank, JE Forged 9.1 pistons with rings, Golden Eagle Rods, ARP headstuds and other misc. items such as I/H/E and all new tranny with Stage 4 CC with ultra light flywheel ect. ect.
So is 66mm TB fine or even 68mm be fine or is either one just a bad idea and yes I do plan on boosting this summer but as for now would the throttle body hurt me in anyway as of now? Thanks.

 

you'll be fine with either tb

 

Thx for the answer.
