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.

stock is something around 52-53mm if i remember correctly... just save up for the 65mm... a tb wont produce hp gains, just improve throttle response

Thats why I am buying the throttle body cause I have no low end power until 3000 then the supercharger kicks in, I need something to give me that jump at the start

it wont give u more power... thats what im saying... it will just improve the tip in feel of the engine. there will be no "jump" over a stock tb. just improved pedal feel.

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.

Yes I have the aftermarket manifold, that is why I wondered if I could get Steeda's 70mm TB, but it say it requires a aftermarket manifold. You think mine would work?
