I've seen alot of throttle bodies on ebay that are brand new and less than $100. All of them look are exactly the same as the Professional Products TB's, and even the new Summit Racing TB's are carbon copies of PP. Some of the ebay ones come with lifetime warranties. Are they really worth buying instead of getting an Accufab for a 130 extra and maybe 2 hp? I'm guessing not for taking a risk of getting a sticking throttle.
Also, should I get a 70mm or 75mm TB? I know the issue has been beaten to death. I'll probably end up getting a Trick flow plenum since i can get a big discount at Summit. On Trick flow's website a 70mm TB and plenum flows better than the 75mm TB and plenum. Is there a bigger advantage going with the 75mm since I have cams?
