I got a x plate MK6 Escort van. Been lowered 100m on the ass with flipped axle
and Monroe gaz struts with apex springs on the front, I have basically a standard 1.8TD engine with out intercooler. What i did to increase the power was do away with the boxes in the exhaust system then enlarged the bore size of the exhaust its self buy fitting the tubular sections from a XR3i and instead of having it come out of the left side only it comes out of both sides. The only time the two pipes join is at the manifold . By doing it has allowed the turbo ( being a low blow) to have less if not no resistance.
I had a cone air filter but found that with it being a turbo it wasn't letting the engine load up so to speak to let the turbo spool up faster ie lag so to change that ive customized a flat carb k&n chrome filter.
Ive fitted a triple paddle clutch and quick shift to going threw the gears dont take that long lol

you can buy racing cams. i know piper do one but not to sure about kent.
The van will top out now at 120mph
