I've heard people talking of a modification to the trottlebody of a C20XE for more power and less jerkiness.
What is this mod and are there any how-to type articles on this?
Any help gratefully recieved
The older XE throttle body has a wedge shaped segment on the throttle plate that restricts the air flow. This can be removed and the remaining holes filled in.
It just so happens I've got an XE throttle body with an LET throttle plate fitted inside (i.e no wedge or filled in holes, just a solid plate) that you could have for £20+P&P if you are interested
