I totally agree, W123love.
My plan is to install a 2.65 rear diff, and by rebuilding the turbo, replacing the compression wheel with a new one, and upgrading the exhaust turbine, I hope to get a little bit faster spool up and maybe a bit more boost down low, say 8-10 psi around 1500 to 2000 rpm under a moderate load. I am hoping to find an oem t3 garrett stage II turbine, which will require machining the exhaust housing to accommodate the larger exducer, but I think it would be worth the trouble.
