3.6 993 engine installed into factory SIX, thoughts and guidance Options

Guys I am collecting parts for my restoration. My car came without a drivetrain so I am looking at a collection of parts and what makes the most sense. I have 90% of a 95 993 engine that I have been collecting - one side of me says high compression dual plug, hydraulic lifters, torque and turn the key it starts right up without any drama. Or a short stroke - and you know where this goes - dual plug, special distributor, P/C's (not cheap) Carbs probably new PMO 46 (also quite a bill) and then the exhaust system with heat.

Does the factory front motor mount work on a 993 engine? I know the tin has to be married from 914-6 and 993 engine tin.

Yup, always comes down to the transmission. What good is a nearly motor when you inhibit it with inadequate transfer of power to the wheels?
If you go 915, PMB is selling the conversion kit in the states, or contact Martin in Germany, but you will need to send in some parts to be modified, so domestic is nice from a trusted source. I’m not a fan of the WEVO/Velios tail shift design. It takes a lot of refining to get it to work and adds linkages and slop points to the set up. It works, but I think the side shift conversion is superior. Bring $$$. The labor to install, or rebuild and install isn’t bad through me, the parts are the main cost driver.
If you can source a 930 box, that would be a neat one to convert as the gears are beefy (but it’s a 4 speed). Currently rebuilding one now. 901 first next to 930 first.


930 slider next to 901 slider. The 4,5 gears in 915 are the same dimensions as the ones in a 901, same with the sliders. In a 930, everything is thicker.

I like the idea of a boxter/Cayman tranz being used. I don’t like having to be mindful of power utilization.
Another option would be Mendeola $$$$.
