Hey all;
There was a recent thread about transmissions which turned into a bit of a gong show... But in any event it got me to thinking about a few things I've been curious about for the better part of a year now.
I guess some background to start, since I'm fairly new here. My 1990 ford probe LX currently has a 92 SHO motor sitting in it. I'm basically all finished except for the wiring. Hopefully it runs, as running is preferable to the other option of turn key and explosion...
Anyways I mated the 92 Yamaha to my Mazda H type lx transmission. Obviously the same bellhousing. There have been probe guys running these h types with 3-400 whp/tq and they seem to hold up to the challenge. It's also a damn smooth shifting transmission.
I guess the main thing that I'm curious about is why the h type tranny needs/is designed with a pilot bearing that is inserted into the crank shaft, and the SHO doesn't need one? Does it have to do with the SHO tranny being built out of steel, rather than alluminum? They also have a completely different spline count, so I had to use the probe clutch with the sho pp and flywheel.
Another thing I've been wondering is what people on this forums opinion of cryotreating transmissions is. I have a friend who has a transmission that's been cryotreated, but he bought it that way from another guy. Worthwhile? I'm thinking waaaaay into the future on that anyways, since right now my goal is just to have the SHO running NA, but rather than spending a fortune on upgrading the motor, my plan in the future is to have a limited slip installed along with a turbo with 10-15 lbs boost. That's why I'm really curious what a person can do to limit transmission damage.
Thanks all in advance!
