I meant air filter, I'm running a HKS Mushroom with a monster Motorsport relocater and a idworkz sandwich plate and a blitz filter. It's very tight but it all just about fits.
Working in a turbo shop we get this all the time 'you've built my turbo and the bearings have collapsed due to cheap shit parts' so its nothing to do with the fact that your turbo still isn't getting any oil due to not changing your oil in about 5years no? Winds me up!
