The 6spd is nice, but it results in a lot more shifting since the gears are much shorter. The ecoboost has enough torque (350 ln-ft!) to pull it through very large gears. 5spd might be the better direction. I think for a NA car, the 6spd is completely adequate. It just doesn't like double the design torque. For the bellhousing we went with a Quad 4 Rods bellhousing and a McLeod TO bearing. They have an internal stop to prevent seal damage. The car is currently using the Exedy NC Miata flywheel and ACT 6-puck clutch and HD pressure plate. Disk is getting sent off to ACT for a new center section to match the Ford T5 splines. The input shaft of the transmission has to be machined down to 0.591in/15mm, which is the Ford 4-cylinder and Volvo diameter. 3 cars, one spare transmission for all of them

That answers the question I was about to ask: What is the pilot. I have a Mustang V8 T5 (23 tooth input which apparently only exists in Ford V8 species) and I had the pilot cut down to Mazda/Chevy size, but he said it was a complete motherfucker to cut because he had to cut under the hardening and he should have used a toolpost grinder but didn't, had to resharpen the bit eleventy billion times because the shaft was hardened, and cutting the input down that much went underneath all the hardening and we're not sure that unhardened steel will live against a NEEDLE BEARING pilot. So I am going to try flame-hardening it myself since I'm too cheap to send it out to be Nitrided. The factory hardened it before so we'll see if I can do it with the torches, yeah? Quick heat until red and dip in oil, quick heat until red and dip in oil, and then a little more heat (but not red) and cool slowly, we'll see if a file slides off and if it does, ship it. If the Ecoboost needs the same input, therefore, that is pretty sweet, which means swapping from 13B to Ecoboost just means an expensive bellhousing, instead of an expensive trans, which would SEEM like a zero sum game except I may break a lot of shit but I have yet to break a bellhousing.

When I put the car back together I think I may throw a set of rods at it an up the bewst, then I can get some more torque and be like to cool kids!!! .... nah I'll probably just wait till I have to pull the engine apart.
I did have a few failures of the rear diff housing, the big alloy "moustache" bar on the MX-5. They have a notch in them so they can fail in an accident and allow the engine/box to move down and back. We fixed that by gusseting the whole back of it with a 10mm alloy plate. PS I do drive like a pansy, but a least one of my wrists is nice and strong! |
