I figured it's finally time to share my current project as a get ready to shift towards plumbing and wiring the engine. If y'all want to see more then just setting up a Turbo II in tiny British sportscar let me know. Currently working on fitting Miata rear suspension and BMW 188L to the rear, while I wait for Turblown's FC3S to FD LIM. While 12A's are relatively common place in a spitfire with almost no cutting, 13B aren't and turbos are no existent for a couple of reasons that quickly stacked up. So far to be happy with engine placement I've had to do the following below.
Notch the frame for: front of the oil pan, Starter, downpipe, coolant drain bolt and VSS(Honda passport)
12A front cover as the frame rails are only a inch wider then the keg
Shorten the shifter by ~6" so it not in my hip
Notched and welded the T2 bellhousing to: Clear the down pipe and a clocked starter. Turbo starter solenoid would eat what's left of the drivers side frame rail.
Designed and ordered a 3d printed 316L Stainless steel twin scroll turbo manifold for a IWG EFR7670. Almost no room for a turbo yet alone wastegates with suspension in the way. Turblowns LIM gave me room of a turbo almost gave up.
Reworked the firewall for the turbo and oil filter.
There's a still a lot of work left to go but engine wise I believe I've gotten over all the hurdles. Plumbing seems manage able with a multi-generational stack IE FB radiator, FC oil cooler and a FD front mount. Still need to finish the design for the 12A style cover if i were to go with aluminum sheet metal how thick would it have to be?
