Forgive me for starting a new thread, I've been trying to research this thru the search function but haven't gotten much success on a definitive answer.
I plan to campaign an '87 RX in LeMons. It has a working 5-Speed Full Time D/R transmission. Though I can't get the "Center Diff Lock" light to turn on, so I have to investigate that.
In my LeMons experience, it is good to have 2 of everything so I am looking for a 2nd transmission as a spare and I found a rather cheap 5MT from a Subaru XT Turbo.
From what I understand, it has a slightly different gearing.
- Gear Ratios: 1st 3.545 2nd 1.947 3rd 1.366 4th .972 5th .780, Rev 3.416 Low Range 1.59
5MT Full Time
- Gear Ratios: 1st 3.545 2nd 2.111 3rd 1.448 4th 1.088 5th .871, Rev 3.416 Low Range 1.196
Is that the only difference? Is it a straight swap?
Given the application (road "racing" hehe), any recommendations on using any other Subaru transmission? Should I run a Transmission Cooler?
The eventual plan is to use the EA82T for a while but eventually swap in an EJ motor.
Thanks in advance for any advice!
