I hope no one's expecting insane rates of progress on this. You will be sorely disappointed if so. But I did manage to find some time to work on it over the past few days. Got the foam crap off of the upper firewall and cleaned it thoroughly, followed by more inner fender degreasing. Then today I pulled the Disco Potatoes (Patatas?) off of the Mustang cast manifolds and did a quick mock up in the 245.
This is more or less the turbo positioning that I'm thinking. Battery will go back in one of the buttcheeks, and I'll cut the OE tray out, so the driver's side turbo should sit a bit lower. Housing clocking angles are not at all defined yet. This is very rough. The angle is to promote free-flowing downpipe design straight out of the turbines, so they don't have to make a sharp bend directly after the turbine outlet (that's bad...mmmkay). Manifolds will be fairly straightforward. Logs facing forward, more or less in plane with the exhaust ports. Then some short up-pipe adapters between manifolds and turbine housings. The downpipes will be the most difficult part of this whole swap I think. There's plenty of room on the passenger's side, but not much at all on the driver's side due to the steering column. I'm thinking that the driver's side downpipe will have to run across the engine bay down low and then tee into the passenger's side. Either that, or maybe each side can sneak under the manifold...maybe.
On the compressor side the outlets will likely feed two separate intercooler cores. I think that's the simplest way to set this up. I might put twin airboxes and filters under the inner fenders, then run tubing up between inner & outer fenders and into the compressor inlets. What could be simpler!?!?
Another confounding factor is that this car will have AC. For sure. It's non-optional. The '05 Mustang has the AC compressor down low on the passenger side, which is fine in & of itself, but will restrict my available downpipe real estate for sure. Here's my planned serpentine belt routing below. I discovered the idler pulleys weren't on correctly for the past 10 years (remember this was a dumb show engine).
Still haven't done a hood test fit yet, but clearance is gonna be close or nonexistant to the rectangular throttle body mounting flange. I still may space the crossmember a bit under the framerails which will lower the engine and give me more hood clearance, not to mention space for manifolds and downpipes.
Next up is test fitting the trans to the engine, then determining fore/aft position and starting on motor mount design.
