ofcourse there was nothing in search except the differences between the two. is it possible to make a 4cyl t-5 into the v-8 t-5 with gears and input shaft or are the cases totally different?

Same transmission, just different internals really.

You would need to change basically everything inside...countergear, input shaft and all the gearing and synchro's on the mainshaft.

Well, here's a more complete explanation.

The 4-bangers gears are a different ratio and made of a weaker material. If you want to upgrade to a V8 spec trans, you need to replace the gears with the stronger V8 versions. Now these have a different gear ratio so you need to change the countergear, each individual mainshaft gear and the input shaft to match.

The synchro setup the 4-banger T-5 uses is the NON-WC setup as well. This means brass synchros for all 5 gears.

Ideally, it would be cheaper to get a used V-8 t-5 and rebuild it than the get a cheap 4-banger box and build it up to V8 specs. T-5 parts are plentiful and good used internals can be had very cheaply. For a T-5 i just rebuilt, i scored a good used mainshaft, 2nd gear and new 1-2 slider for $100. Sometimes you'll find guys with 2-3 broken T-5's sitting around. You can usually get em dirt cheap or free and take em apart and slap together 1 good T-5 with a rebuild kit out of the parts you have, and then sell the leftover good parts on ebay or the classifieds.

Just remember, the 85-89 T-5 has a different gearset than the 90-93 trans. The 90-93 trans has a slightly higher torque rating so it's more desirable. The synchros and other non-gear parts will interchange, but the countergears and individual speed gears will not

yeah, i'm kinda ummmmmm, i have a pedal assembly, and a cross member, and am slowly piecing parts together for a t-5 conversion. i'd love to have a built aod, but i was originally lookin for a stick anyway, and i know if the aod ever goes i aint gonna have 2 grand to do it right, so while in this process i'm trying to familiarize myself with t-5 stuff so along the way if i see something dirt cheap i can add it to my t-5 conversion stash. i'm assuming when the time comes i should be able to find a excellent working t-5 for 500 or less, but i don't know enough about them to know whats what, yet anyway. i see alot of them on e-bay but thats kinda a crap shoot depending on what you pay for them. i won't be dragging it, just need somethin that'll be good for what will be a mellow driveable 13 second car on the motor........so a t-5 from what i've seen should work for that.
