I look at it from a cost/benefit perspective, and was limiting it to the available simple "bolt-on" options for the Z32. While you're preaching to the choir about the ability to rebuild journal bearing turbos (keep in mind, I went through hell and back to fix my GT2530), I'm not really considering hybrids like you mentioned. Yeah, there are a lot more journal options out there, but when you consider a straight up Sport 600 or Sport 650 as they come from JWT, there are better ball bearing options for the cost. (That's basically what I was getting at.) For example:
Sport 600 ~ $2,450 (Ultimate Z)
Sport 650 ~ $3,295 (Ultimate Z)
GT2860R - $2,190 (ATPTurbo.com)
GT2860RS - $2,350 (ATPTurbo.com)
Z1's GT600 - $2,395 (Z1 Motorsports)
Z1's GT675RS - $2,850 (Z1 Motorsports) Considering the GT2860RS is, essentially, a Sport 700, you're getting more performance (and better response, from what I've heard from Sport 600 owners) than the Sport 600 for less money. Same goes with the Z1 turbos... both cost less than their JWT counterparts. The "Thrust bearing turbos are so yesterday" comment was to be taken light-heartedly, I don't fully believe that (especially considering how well the Sport 500 has worked out for so many people). I do, however, feel very strongly that the JWT Sport 600 and Sport 650 designs are not up-to-date, and are therefore less favorable than the newer turbos, which are generally ball bearing nowadays.
 Putting eBay "performance" parts on your Nissan 300ZX is like putting Pep Boys wheels on your Cadillac Escalade... even people on welfare know better. |
