T5 Trans Crossmember
I have fallen headlong into an L33 and Miata build. I have the long block and the car now, so I'm committed. :D
What I want to do is run a T5. I am thinking a Chevy "621" bellhousing, a 3rd gen F-body T5, an automatic flex plate and a twin disc setup. Am I missing anything? Really, my question is, does anybody, in any kit, offer a T5 crossmember that corrects for the 17deg. off clocked mount on the F-body T5? I thought I saw a picture of one somewhere. If it's tied into chassis stiffeners, that's even better. I plan on using the rearward (or standard) V8R subframe, and probably the Monster Miata 7.5 diff hangers. Also, does anybody know about where this will put the shifter? |
An automatic flex plate???
That doesn't sound right. Mike |

The TD setups are pretty sweet. We have a company locally building 12 pound clutches for 2.3's which hold a TON of power. They also use a flexplate.

Gotcha. I should have googled it before I responded.
Never too old to learn, eh. Mike |

When you go to buy the Monster Miata rear end set-up ask Martin if his trans mount will work. It works with T5's used in Mustangs.

-Jason I know the Ford T5 doesn't have the offset mount that the F-bodies do, but if it's in the right spot, that's most of the battle I guess. Is Martin's crossmember part of the chassis stiffeners? |
His kit does not require frame stiffeners. His cross member attaches directly to the Miata frame rails.

I've been considering the V8RSpec frame rail reinforcement kit w/ T5 x-member, for my build. Seems like killing two birds with one stone. |
My Hard Dog hard core bar with the DIY Roadster door bars stiffened up the chassis more than any sheet metal frame covers would.

A fair point...seems Miata guys LOVE their frame rail reinforcements; it's a popular upgrade
You're almost caged, in that car...unfair advantage, lol |
So MX5.3 did you ever figure out your cross member issue?
Having owned a bunch of Camaros and Firebirds I would start with a 4th gen F body V6, T5 cross brace and just extend it a bit. That's a $5 part in a bone yard and at the exact angle you need. |
