I've got a weird one, I've got a 2.4 T5 bottom end with a 2.3 ported head (put together by shem a few years ago). It's going into a kit car, but before I do, I do have a spare 2.4 T5 head. What would you do:
1. Keep the 2.3 ported head (single VVT)
2. Switch for the 2.4 twin VVT
I'm going to be taking the head off regardless to put forged rods in there.
The difference between the 2.4 and the 2.3 does seem considerable in terms of stock tune-ability but is this a down to the twin vvt? or is it something else?
