Editing XF Throttle body (section)

===Fitting the XF TB to the plenum body===

Why do it? Well, XF TB has much bigger hole in it compared to the [[RB30E]] TB don't it?
Surely more air gotta = more power

This was done on a manual [[RB30E]] (in a VK).
I would assume doing it to a turbo would be pretty much exactly the same.
Apparently there are 2 different types of XF throttle bodys.
I have no idea what one I have. It came off a 1979 fuel injected ZK ford fairlane.
Shown below is the one I used.

Ok, now to start off with, take the top part of the plenum off completely from the intake manifold (refer to a Gregory‚Äôs manual, or just keep taking stuff off until you get it)

Take off the old VL TB.

Get XF TB and modify the holes so they are closer to the center.
You can do this using a dermal sort of tool, or a rats tail file.

Flatten edges of the TB to get bit more room for head of the TB screws using a small flat file

Grind the heads of the TB screws so they are smaller diameter.

Bolt XF TB onto the plenum and make sure all the bolts that hold the TB on can screw ALL THE WAY in.
