also, it sounds like your transmission being 3 miles long is causing all sorts of problems. Now that you have the motor, it might not be unreasonable to revisit your transmission choice and maybe find one that will be less annoying to fit.

Well see I own the transmission now, which means if I go another route I am going to have to buy a new transmission and try and sell this one.

[formyhealth]

they make high-clearance subframes for installing rear-sump motors.

seems like this kit includes an oil pan with a slightly different profile - http://spartaperformance.com/2-0l-fo...-rwd-mounting/

Yup that's the kit I own, which has the annoying rear sump hump.

^I vaguely recall reading a miata 6 sp (NC?) trans bolted up to an ecoboost. Might be shorter...Miata parts are usually pretty cheap too.

You'd be correct, the NC Miata transmission fits fine, it's the strength and durability of the transmission which is the issue on that one though.

what kinda power figs are you thinkin here?

Looks like ~350 ft/lbs of torque and ~280 HP with the Focus ST throttle body, but I'll be using the Mustang TB which is about 10mm larger bore size.

[wworm]

oh wow thats a freakin boat load of torque. Probably a good call foregoing the miata trans.

Right? It's an amazing amount of torque out of 2 liters and 4 cylinders.

[wworm]

yeah wow. Are there any other trans options that seem to be able to hold up to that...that are also not as long? Because shortening that up might do you a lot of good. Or converting to front sump.

The t56 is shorter, and also allows for mid shift which makes mounting more flexible. However to do that the cost is about $3500 for the kit and bell housing adapter.

I maybe able to modify the shift linkage while maintaining the geometry of the arm and selector which could give me about 2" if cut and welded. However, moving the center of gravity back (me moving back and the shifter and steering column towards the center of the car) may be advantageous. I'm not sure what I'll do yet, but will have a better idea when I get the pedals mounted.

t56's are stupidly expensive. Hopefully this can be mounted in a way that doesnt involve cutting the hood and having to reach to the back seat to shift lol.

That's my hope too! I really don't want to put a dogleg on the shifter either, but I'm sure I can get some thing figured out.

i was really excited to see this. I have everything in spreadsheets to do this swap, well sorta.

I tune and upgrade ecoboost powered cars for a living.

Mountune USA sells a dry sump for the ecoboost. Pretty expensive but it will solve your oil pan clearance issues and be able to make the motor really low.

If not, there is a huge balance shaft at the bottom of the motor taking up half the room in the oil pan. You dont need it. Get a delete kit and modify the oil pan so you can make it full front sump (i think you would go back to the FWD oil pickup) or do modify the mustang pan and do the arc asylum subframe.

Man, this build is sweet! Definitely going to be keeping an eye on this.
