On to the electrics, will be running Motec m48 with a OEM harness. I made a 55pin adapter to transition from Motec to OEM harness. Also this set up requires a 5 pin relay to activate the unit.
Big thanks to Trophy (rennlister) on helping with the wiring diagram.
Display will show AF mixture or boost.

Finally with the break in the weather I got a chance to install the motor in the car.
I used my trailer to get the rear-end up.
I got really lucky on my intake pipe location since I never considered the rear suspension frame for layout.
Back on the trailer

I'm sure you're not intending to race the car either but having those catch cans inside the cabin is against the rules (at least FIA). It also not allowed to have such big openings in the firewall for the air intake, at least according to the current rules.

Otherwise you have done a great job!!!

Nice!
I have to take the picture of your turbo intake pipes and figure out how you got those to fit, as it is a problem getting big intake pipes to fit on a turbo (I've tried) due to the suspension. Might be the headers locate the turbos further back in your car.

Basal, the headers are located in the stock location. I was able to come through the engine tray since I don't have the power steering pump and also the heater box. Lets just say it wasn't easy but I got lucky missing the rear suspension frame I only focused on the spark plugs when I routed the flex hose. The Fiber Fix wrap worked perfect, it stays very pliable for 10mins so when you wrap it around the flex hose you can position your hose in any direction or even pinch it in the clearance issue areas. After 10min it gets very hard like a cast and it will protect your flex hose from anything your tires throw at it. You can pick up Fiber Flex wrap at home depot for $18-10ft.

Flammable liquids (Catch cans) inside the cockpit are a big no-no... As an instructor, I would not ride in a car with them exposed. I would have serious misgivings about having the intakes in there too...
I know I'm a little paranoid, but if you plan to DE and need/want an instructor, please reconsider. Otherwise, I'm dying to see this monster run !

Jscott82, I can see your point regarding the location of the catch cans. When you say " big no-no" are you referring to a PCA rule. Motor oil is not considered flammable but combustible liquid with flash point at 400F and above. I think we both will agree that with 400F oil temp I might have a bigger problem than 1 quart catch can in the cab.
Trust me I would prefer to have them inside the engine bay but just can't find the room for them, may-be under the fenders.
Will reconsider the location if required by PCA.
My final plan for the intakes will be rear window NACA duct with filter box in the back, standard location that I have seen in other cars

I know it's against the rules to have the catch cans inside the cabin but actually from a safety perspective, I think it is safer to have them there vs. inside the engine bay. We all here on 993 board know about the tragic incident a rennlister had with car catching on fire due to home made oil breather catch can.
Point is, if the catch cans leak/overflow, they won't cause a fire hazard inside the cabin but if they leak above the engine and oil ends up on the headers...boom!

Or all over the track!! Where someone else will pay the price.
Juha, is that rule only apply to the PCA racing events or all?
I guess I need to start reading the rules instead of doing what I think is right .

I don't think your catch cans are a big deal, they can be easily relocated inside the engine bay later if wanted and the holes in the firewall plugged.
The bigger issue is the air filters, and not the filters themselves but the large openings they provide through the firewall. i.e. a fire in the engine bay will easily spread into the cabin through the filters.
The correct way to do that would be to run the ducts outside of the car with fire proof ducting (into the rear side windows for example).
