Single Turbo Conversion On R32 GTR.

[StevenJames32]

Hi everyone, I have purchased my first GTR and I want to do a single turbo conversion to it. I've been doing as much research as i can and there are a few things that I can find and need to know. I need to run a coolant feed, coolant return, oil feed and oil return for my turbo setup.

Here's what I know so far:

On the hot side of the rb26 there is coolant feed, oil feed and oil return. Coolant return will be going around the front of the engine to where the thermostat is located. I will need to block off the rear oil return port. I will be running a turbosmart boost solenoid so any of the factory boost stuff wont be needed.

Now onto what I don't know:

1. What do I do with the coolant / vacuum hardlines that run around the back of the motor?.

2. What do I block off or loop or move or remove?. I will be running the OEM intake manifold.

3. Is there anything in particular I need to buy for the cold side of the rb26?. I already have the intercooler and pipes sorted.

If you have any pictures or information it would be appreciated. Thanks....
