Default 944 turbo 3L build

I'm jumping on the winter build thread bandwagon with hopes that this won't turn into one of those abandoned projects.

My 944 turbo's 2.5 8v engine is getting mighty close to 300,000km and while it runs fairly well, it leaks all over the place. Everywhere I park it leaves evidence that it was there. I had planned on pulling the engine and doing a straight forward rebuild and reseal, but after building my race engine, I'm a bit more confident to do a bigger build. I found a nice low mileage S2 (3L 16v) engine in BC for a great price, so I'm using that as my starting point. Step 1 is engine tear down and inspection to make sure I have a good block and head to work with. So far I've found some bits of plastic in the sump from the oil level float, which I'm guessing fell apart as I was wiggling the oil pan off.

Subscribed! Also, first to say "shit is about to get real".

Just for those outside the 944 community, a 3 litre boosted 944 is the holy grail. They have been dynoed at 600hp. 3 litre is also not the limit, there is one in the UK at 3.6 litres based on this block. We'll be expecting BIG things Justin, almost undriveable BIG, don't let us down!

Stock oil baffle and windage tray? You bet! Thank-you very much Dr. Porsche.

I don't think I'm going for a monster engine with this one. I'm shooting more for the perfect street engine. I want response, quick spool, good mid range and reasonable top end. To get there I'm going with twice the valves, and bigger displacement in a more rigid better built block. Not sure on which turbo I'll go with, but definitely something more modern if the K27 won't work for me.

There should be more pictures as I continue dis-assembly. They are as much for my reference as they are for your enjoyment. I figure if I'm going to document it anyway, might as well make it public and searchable for future generations.

Do the 2.5 turbo intake and exhaust manifolds bolt up to the 3.0 head? What exactly has to be custom? I've got a stock turbo oil cooler and hoses if you want to run the dual setup to cool the extra HP.

I'll need a custom intake manifold and have the exhaust modified to match up with the crossover pipe. If anyone knows of anyone local to make a manifold, that would be helpful. I'll reuse my FMIC and FMOC.
