Hey guys
Hard out saving up for a turbo setup for the Q. I've decided to put my own kit together and fit it myself.
Just a few (a lot of) questions:

Will my engine handle it?
I know the weaknesses of Blacktop non turbos, but the engine is only 183000kms young, so...
Also, I only want to run a max of 15PSI through the engine anyway. Will the standard pump handle this? What sort of power figures would I get out of this if I did?

High mount or Low mount?
I've heard low mounts are much easier as you can use GU componentry for future upgrades etc.

What size turbo?
I've been looking at TD05 18g 6cm, but recently noticed some people running Garrett ball bearing turbos. What is better for just a weekend play toy, that never tows or carries heavy loads? Are ball bearing setups better or less reliable as I have heard?

Mamba Turbos - Are they any good?
They look like good quality, and come with all the oil feed, oil drain lines and water lines.

Jrace Exhaust manifold - has any one used them and would recommend them?
They look awesome and you can get a standard GU replacement, so it makes it much easier. Is $490 a reasonable price for a manifold?

Purely oil cooled, or water cooled as well?
Purely oil cooled seems a lot easier to fit?

Weld the oil drain into the sump?
Is there any other way, cos I'm NOT a welder!

What pressure on standard fuel pump?
I don't want to upgrade the pump, but do you reckon it would handle 15PSI if I intercool it?

W2A or A2A/Top mount/Front mount intercooler?
What is the most efficient, that is the easiest to fit?

Piping size under bonnet?
I was thinking 3" the whole way as I am getting a Patroldocta 3.5" airbox and the inlet to most turbos and intercoolers is 3".

Would a GU exhaust kit fit onto my coil cab - all mounts lining up etc if I used the standard exhaust manifold?

Where to mount the EGT probe - pre or post turbo?

Any tips that would make DIY fitting easier?

Sorry to ask so many questions but look forward to some replies from you more experienced guys.
