throttle bodies that will fit on3 foxes

Hey, alot of people have already run into this but i thought it might help some guys just starting there turbo build, the 90 degree coupler from the charge pipe to the throttle body has an inlet diameter of 3" and many aftermarket tb's have an inlet casting of 31/4", there are ways to solve this if you aready have a TB that dosnt fit. here is the inlet diameter of the tb's I've had it might help someone looking

3" Throttle Bodies= factory, ford racing 65mm, mac 70mm, accufab street 65mm and 70mm

3 1/4" throttle Bodies= BBK/Edelbrock 65mm-75mm, professional products 65-75mm,

if anyone would like to add to this list feel free

boiling them makes them nice and flexible also.

after it gets used to being on the car it will come on and off easier.

Couldnt get mine to fit on my 75mm tb so I installed a coupler between the elbow and the TB. Bought it at Autozone for 12 bucks or so. It was a thinner/cheaper silicone and was easier to stretch. If I had it to do over I'd buy a 90deg silcone elbow from siliconeintakes.com with a 3 and 3 1/2 ends. I used this on my last car and the 3 1/2 fit the 75mm TB.

wd40 is not silicone friendly it will actually break it down over time, an cause it to degrade, leading to a air pocket in the coupler or complete failure, &/or leaks. highy suggest vasaline or water. or any other neutral pertoleum by product.
