I am fitting a single to4z to my gtr and need to make sure of what pipes l need and what pipes l can block off.( Please correct me if l am wrong)

The pipes in the picture are the ones located to the back of the block and a right bitch to get at, if l might add.

When trying to take this bleeding pipes off, l bent them, as l have heard almost everyone has.
So l have cut them were the bend was. (makes more room for my wastegate)

As far as l know, pipe (A) can be used as the single water return from my to4z.

Pipe (C) is the vacuum pipe that can be attached on to my tail wastegate.

But what is pipe (B) for, and can l block it off.

Any other suggestions as to what pipes are needed, or a better way of plumbing A pipe that l have not included, would be appreciated.

Keeping in mind that the setup l have is the old hks low mount.

The oil and water feed from the block has already been plumbed in, the diamond shape return oil flange to the bottom/rear of the block has also been plumbed in, the big oil return pipe to the front/bottom of the the block has been blocked off.


cheers.

B goes to the wastegate actuators & comes from the original control valve on the offside strut.
So, do l block off pipe 'C'

The tail 44mm wastegate has two banjo/unions, do l use both or block one of them off.
