90 gsx, what can you say? they're born dicks. lol
especially this one.
what to do for 2wd dyno
You could actually take it to a transmission builder, good one and have it reinforced so it wont expand when you're transfering power.
I've seen this done this before on this forum and it's something you could do with a new t-case or older one that's in good shape.
one guy in TN is good. He builds turbo too (from my friend with datson and supra).
I think the Works is developing one, from what I heard as a rumor but nothing out yet.
Good luck.
