I've done a few searches on the forum and from what i've seen no one has come to a conclusion to this.

What is the thread size of the bolt in the head which can be used to feed the turbo? i've seen 1/8"bsp threaded or 1/8"NPT which only have 1 tpi difference.

If anyone has got this bolt out could you please count the TPI.

Cheers Guys

Where abouts are the oil feed and return locations? I'm looking into this now. Was gonna carb a k10 but now i wanna turbo a k11! haha. I'm guessing the return can just go into the sump so mostly where is the feed? Any links to somewhere online i can order the part from? Do i need a sealent to fit it or just bolt it up :) Thanks guys.

yeah the return will need to go to sump, ive got an adaptor on mine which basically a hole drilled in the sump (whilst taken off and cleaned after) and a little fiting bolted on. as for the oil feed you can take it from by the oil filter with a t peice adaptor or you can take it from the head from a gallery plug which u can see on the far left side of the head on the exhaust side
