"Second, the stock duratec TB is about 63mm ID. The aftermarket ones are 65-67mm ID. I like the 2nd plate idea in your Suzuki TB, but 42mm just ain't gonna cut it. And, no offense, but if you had done your research here first, you would have known that... so please, for your own sake, ask questions here FIRST"

I need to clear up some misconceptions. Firstly there will be four throttle bodies used at once (not one) effective area would equal an 84 mm single throttle body.


I am running an SCT tuned motor already. 6% additional fuel. It passed inspection. There are no trouble codes.

Not looking for 200 wheel horsepower, but 200 225 engine horsepower. This is but a modest increase over what I have now.

The only part of the stock intake I will be using is maybe the first two inches off the head. The throttle bodies will go there.

I will be drawing air over the stock MAF sensor but it is now placed in a much larger Cosworth intake tube.

Thanks for the interest.
