Hello, from UK, lots of questions regarding turbo charging a 3.2 carrera!

Well where do i start? After having trawled every Uk web page going I found absolutely zero information regarding turbocharging my 3.2! Luckily I stumbled across this forum. I have a standard 3.2 carrera that I have widebodied, RHD converted (german import) GT3 brakes all round, Bilsteins , turbo 2 wheels etc.

My next step is to turbocharge the 3.2, and so I have a few questions you may be able to help me with. I have seen lots of info about oil returns, which is great, which leads to my first question. Where do i take the feed from? I would have thought tapping from the oild pressure switch area is generally the best thought, but correct me if I'm wrong?

Next question... I have a GT35R I'm using , I also have Autronic SM4 management. On the mid 80's 3.3's I notice they use the intermediate pipe straight into the turbocharger with the original heat exchangers and cross over pipe. On alot of the pictures from this site, you use a set of parellel heat exchangers to the turbo and then a seperate external waste gate pipe. Is it a large restriction using the original heat exchangers with a suitable flange? Or shall I purchase a similar set to the ones I see on here?

Finally I'm using a 915 3.2 box. Will this stand 450/500lb/ft of torque? or will it rip it to shreds?

There are far more questions I have but these are the main 3 I need awnsering at the moment. I'm sorry if they sound so basic, I have built some pretty quick cars before, but never really played with porsches (this is my first one). Many thanks in advance for any help towards my project, I will be hopefully buying parts from the states as they are so much cheaper than in the UK!! (and people here seem to know what they are doing!)
