Hey can anyone tell me the stock size of the 2.0 zetec throttle body? Steve Monroe of throttlebodys.com said he could bore it out 5-6mm over for $100. If I new the size of the stock I could compare against just buying the 65mm, but for $250.
go with the 65mm tbody. If you have a blower installed and is dumping into the stock tbody, then would mean the tbody is the first restriction right now. Yes the 65mm is only worth 1-3hp but dont forget that parts compliment eachother. I would bet that a 65mm tbody would be worth at least another 5-10hp. If I was you, i would do the ford racing manifold and tbody. That would compliment the blower very well.
