A question for the FL1 1.8 petrol owners. Approximately how much space is there between the bottom of the sump and the plastic sump shield?

I know that the exhaust is bolted to the sump itself and I'm hoping that there may be 70 to 80 mm below those those pipes. Is there?
 
At the moment the gap between my Freelander's sump and the undertray is about 10 foot - cos I took it off a couple of weeks back and can't be arsed to fight with it to get it back on!

I here that a lot. I don't have a problem fitting them myself.

Why do you need so much space?
 
Planning header construction. It's tricky keeping the primary pines on a flat plain, I was thinking about putting two on two but in a diamond arrangement. That would make it essentially two pipes 'thick'. Most likely to close to the bash plate, unless I make a modified one!

Have you measured how long you can get the primaries will be before joining the secondaries? There's plenty of room forward of the head to gain extra length. If you can squeeze in 20" primaries, you won't loose out to much torque over longer pipes. Keep the primary ID the same as your enlarged ports to avoid back flow.
 
I've been giving it some thought. I can get the primaries to beneath the sump in a skewed two on two set up, then there is the four into two [about 6 - 8"] which would be beneath the IRD the two into one about a 6 - 8" and then a longish collector of about 8" where the Cat is and the relocated O2 sensor [ goodbye cat]. There is always a balance of pipe diameter / length to keep the torque in the lower rev range. This plan is on the back burner, just want to get the beast going!

Sounds feasible to me. You will have a nice effective manifold there. Dumping the cat and fitting a nicely made straight through system should have you seeing 140 + Bhp with a nice effective cold air intake.
My old similarly spec'd MGF 1.8 made 146 Bhp on the rollers. Giving 130+ ftlb of torque too.
