stlunatics2oo3 Posted November 3, 2002 Author Report Share Posted November 3, 2002 is it possible to put a bigger size throttle body on my car and if so how big and best brand ? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted November 3, 2002 Report Share Posted November 3, 2002 RSMracing makes a 62mm throttle body. It will make some difference. But not alot unless your doing other things such as some porting on your intake. Quote Link to comment Share on other sites More sharing options...
