Hey guys, I'm planning a b6284t swap for my 78 242. I need some guidance on choosing a suitable trans for the swap. My initial power goal is stock t6 (270/280ish) but I'd like the platform to support at least 400 hp. This won't be a race car, just a fun project to learn more and push myself, bring to shows, and occasionally have some fun on the interstate. I'm not too concerned about getting the nicest box, just one that is strong and works. If I can find one locally to pull at a JY, that is ideal. I assume any non-volvo box will need a custom flywheel/clutch/pressure plate/slave cyl/shifter bracket set up which I would look into further once I've narrowed down the list. Here's what I've found from researching so far.
Option 1: M90
Found in 1994-1998(?) 900s overseas. 97-98 H, H2 and L2 models are most desireable. Not being able to get one locally/stateside is annoying but not a deal breaker if it will save enough headaches down the road. I've read reports that they share parts with m56, but not some crucial pieces. Read a thread here where Cpt. Bondo said he pushed ~500 through his for a while, but I can't find the build thread, unless this is it. I started out not even considering an M90, but from what I've read it seems like a strong candidate if I can find one.
Option 2: T-5
can be found in 80-95 v8 mustangs. Looking around on Row52, there are plenty of these in the yards near me. Good for 300 #ft tq according to a few sources. This seems to be cutting it close for a b6284t rated 280tq, and I'll be wanting closer to 400 once it's all dialed in, but maybe they can be built up? I've driven in two t5 swapped cars, one TD 740 probably making close to 200 wtq, the other my buddies MS'd 242, which he estimated 300-350 to the wheel. Nice shifts, felt good under power, better rations than m46. This seems to be one of the most popular swaps but that low torque rating seems questionable. Adapter plate is available from Deeworks.
Option 3: CD009
comes in 06+ VQ cars such as Nissan 370Z and Infiniti G37. I couldn't find one listed in a JY in 100 mile radius. I'm not 100% on all of which models they came in. There are probably some deals in the forums, etc. where I have not looked yet. According to this they are commonly put behind LSs, so they must be pretty strong. In one thread I read the OP noted that there was not much trans tunnel bashing needed to fit. Adapter plate for a Whiteblock also available from Deeworks.
Option 4: T-56
Found in 93-02 Camaros and 97-07 Corvettes. Rated from 350-450 tq depending on the year and flavor. None in the yards around me and likely more shekels than the rest, but the strength is attractive. Seen one thread here of one used in a 960. No off the shelf adapter plate available that I know of. This is the most attractive option to me in terms of strength, if I can find one within a few hours drive.
Option 5/6: Toyota W58 or R154
All I have found on the forums is anecdotal evidence that the r154 is stronger. According to wikipedia the only US market car they came in was a mk3 supra, so chances of happening upon one in the yards is slim to absolutely, positively, snowballs-chance-in-hell zero. I can't find a reliable source for what kind of power they can take, but if they hold up behind 2jz drift cars chances are they're strong enough. I imagine that drift tax will make them hard to find cheap.
Option 7: BMW Getrag 265
Came in a number of BMW models from 84-05. Hard to tell which came with a 260, or the beefier 265. Not sure if there is a big difference between them. Seems like it could be a viable option if I can nail down which models are good to pull from. One documented Whiteblock swap here
Thoughts?
edit: I tried searching "m90" in advanced search for the whole forum and get nothing. I was hoping to search classifieds that way.
