Sick Speed 70mm Throttle body
So Ebay says the 70mm throttle body sold by SickSpeed fits a 4B11 engine. I understand the 4g69 throttle body is 63mm and requires boring, so how is a 70mm throttle body supposed to fit? If anyone knows if this 70mm fits please tell me because it would be nice to go bigger if possible.

I was looking at that also. It looks like A lot of work for little payoff. I'm sure it would cause more problems down the line. You probably wouldn't even notice the difference. But thats just my opinion. I would like to hear from some one with experience with changing the throttle body.

DONT DO IT!...best upgrade from a 4b11 N/A TB would be a 4g69 throttle body, don't go 70mm TB
Y? cause not going to do anything other then eat more gas and it would be too much air flow,and you wouldn't get much out for a N/A, unless your turbo then its a diff story..
