Ah, Ive literally just posted up asking about mounting a cooler in the front bumper as that seems to have a lot of wasted space in it funnily enough.

The extra length on the new engine is largely belts and plastic covers etc, so shouldnt be a significant amount of extra weight ahead of the axle, especially as the whole engine is only the same weight as the YB anyway, so essentially its going to be equivalent merely to moving the YB a couple of inches forward at worst.

I dont really want to chop the bulkhead up as I want to keep the standard RS500 interior and dash in it if I can.
