Ok so, I've bought a new exhaust manifold for my rev 3 turbo, buuuuut due to me using a rev 2 block the oil filter is totally in the way

So, simple right? Oil filter relocation kit.

Uhhh nuh.

I still dont have enough clearance between the manifold runners and block/oil cooler to fit an oil take off plate.

My question(s).

How

'necessary' is the stock oil cooler? Can I just delete it and use a shorter oil filter bolt

(taken from a non oil cooler car) straight from the block? Will I need an

'aftermarket' oil cooler or can I run without one?
