We talked about the Focus set up but, of course, I have the slight added problem that my engine is a silvertop ( and therefore arguably a pre-Focus engine). A daft question perhaps, but is that going to mean different chcharcterisitics and so rule out using a Focus 1.8 kit as a basis?
I’m thinking we may be able to replace the existing airbox with a Maxogen BAB65, but it may well not clear the bonnet – the ducting would also be a bit long, but looking at the standard setup I think it may work a little better.
We could leave the Maxogen in the same place as the filter housing is now and perhaps go for a ' +4 supersports-type bulge on the LH side of the bonnet but I'm getting very conflicting data as to whether that inside edge is still a low pressure area
The only other option I can see would be to move the MAF towards the front of the engine bay – this would involve lengthening the wiring, but with only 5 or 6 wires, this wouldn’t be as big a job as you think. This would allow us to hopefully still squeeze an airbox in and run a very short duct. As long as the relative distance from the MAF to the throttle body doesn’t change much, I don't think it should affect the performance.
