As above what diameter is the pipe directly off the turbo and what's the best air filter to use?

I'm running a GRP a Cassie filter. Its huge! It has a trumpet so joins directly to the hose that used to go to the metering head

I don't have that metering unit house I found a Ramair filter that will work but it's for 2" pip I'm sure when I measured the turbo it was 40mm not 51mm

Its been a long time since I measured the turbo intake but sure mine was 50+mm

Its not a standard turbo though.

If your using silicone hose it will give quite a bit and may fit both ends if you choose the correct size for the smaller of the two ends??

I asked Matt Lewis Motorsport and the say 60mm seems big to me I'm using the standard turbo so I'll take a better caliper home and have another measure I think lol

Good plan

Makes sense to me. Been ages since I had the turbo off etc!

was 60mm (i measured the turbo) so ordered a ramair filter
