Is the RB20 and RB25 direct fit?
My Arashi "direct fit" turbo has a larger opening and bolt pattern. Can I bore them out? Widening the hole spread?
Its a direct fit RB25 turbo we are installing on a RB20

I would think you could drill the holes a bit bigger and do a nut and bolt setup instead of the threaded bolt deal.

I have a OEM rb25 outlet but it wont do you any good on the Arashi turbo
