Outer Limits 4x4 Board

I am doing this mod at the moment with a factory set-up, no major drama's yet, but....
I need a longer throttle cable, I need to get a flanged neck made for between throttle butterfly and manifold inlet. I also need to know the thread size of the oil feed pipe collar, as I need a 1/8bsp to what ever that thread is for it to go into the block, I will also have to get a bung put into the side of my sump for the oil drain
There was a fitting of 1/8 bsp thread in the end of the inlet manifold, is this for a gauge?? Can I just but a bung there or is it important?
I am not doing any internal mods at the moment, but I only plan on running about 6psi, when it blows I will re-build with the turbo pistons etc. etc.
So if anyone's planning this mod, be aware of thses small things and if anyone can help with my drama's your advice would be appreciated

why would it blow?..if its a late sd33 n/as it has the turbo pistons etc.

Acording to a parts book I have, the pistons and linners are the only different internals, apartently the turbo pistons are bigger diameter???
I don't know for a fact though

just make sure you fit and use an egt gauge..then you should not have any probs, as long as you keep an eye on temp!
