Some of us who put on 2-5k miles a year would take years to achieve...life it too short to not boost for 3 years, especially because of a cheap z32 transmission, good lord.. This isn't no t56 6k swap. The way I look at it, its no different than driving a z32 off the lot in 1990. I'd drive it civilized for the first 1000k and use OEM manual trans fluid.
