My turbo is a gt20 and has a o clip around the back of be snail of he turbo,
I have a replacement turbo is it possible to take the snail off with the hole shaft n rear exhaust fan of the new one and slide it into the rear exhaust housing of the old 1 which is still on the car!
There is no gasket between this joint! It is just clamped with this o clip!
The rear exhaust housing and elbow is fine no crack etc!
