well dont take my advice on it but something tells me it would be best to pass on this.

 

If you know how to fab then you could make it work. You wouldnt have the electronic throttle control. Probably could only tune it based off the BISS and the length of the throttle cable. Alot of guys going for high perf that need a huge throttle body run the cobra and gm 90mm throttle bodies. That one seems like a copy of a generic BBK throttle body. Your OEM one will suffice for most needs. You can have a huge intake, huge throttle body and have small straw runners (choke point). The harmonics or velocity of air coming in is what ya want.
