jgkurz Posted July 9, 2003 Share Posted July 9, 2003 Hi all, After talking with some folks and reading this forum it seems that the T04B 60-1 wheel would be a better fit for my car. I've heard it's possible, even suggested that the 60-1 wheel be installed in a T04E housing. My turbine is a stage 5/10 blade .63 T3. Can I get a response from people who have done this upgrade? I'm looking for feedback on driving impressions and recomendations for a turbo shop that's done this conversion. Thanks, Quote Link to comment Share on other sites More sharing options...
speeder Posted July 10, 2003 Share Posted July 10, 2003 Hey John, I have a 60-1 in a TO4e housing , with probably a little bigger turbine wheel than yours (P-trimT4) in a T3 turbine housing. I've been very happy with this turbo - I have 12psi by 3200 RPM, with big power made after that. I previously had a T3/t4b (stage III .63 turbine with Super V compressor) that spooled instantly but pooped out at the high end. I would recommend you go to the 60-1. You'll like it.

yo2001 Posted July 10, 2003 Share Posted July 10, 2003 60-1 is sweet. I went from stock T3 to 60-1/stageIII (still in To4B) and I've more power after 5000 rpm and still spool before 3500 rpm. Quote Link to comment Share on other sites More sharing options...
jgkurz Posted July 10, 2003 Author Share Posted July 10, 2003 Are you guys running a .60 A/R T04E compressor housing with a spacer? Quote Link to comment Share on other sites More sharing options...
yo2001 Posted July 10, 2003 Share Posted July 10, 2003 I'm running .60 T04B and no spacer needed for it. .60 T04E I've seen, all runs spacers unless the turbo is clocked downward. I think ScottyMiz managed to do .70 T04E housing without a spacer. Quote Link to comment Share on other sites More sharing options...
speeder Posted July 10, 2003 Share Posted July 10, 2003 Mine is a 50 A/R housing but it has been machined. I believe the net works out to around 60. I do use a spacer, but have heard of several people who grind the exhaust manifold for clearance. IMO the spacer is the best solution because it gives a bigger air gap. I don't think that there will be any intercooler tube fit issues with this small a spacer - the flexible hose connections easily have that much play.

jgkurz Posted July 10, 2003 Author Share Posted July 10, 2003 Rick, For me the spacer doesn't present a problem for my IC but for my Scottie downpipe. If I move the turbo out 1/4 inch then I will probably have interference problems in the transmission tunnel. My T-5 is going in now so I'll be able to check the fit soon. Who did the custom work on your turbo? Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted July 10, 2003 Share Posted July 10, 2003 I have the 60trim T04E with a stage V turbine, and it is a 60 AR compressor housing, and I used a spacer. I had no problems with the intercooler fitment, and I am considering replacing the compressor wheel with a 60-1. It is a great wheel. I have full boost by 3200 rpms, very good response, and lots of power up top. Quote Link to comment Share on other sites More sharing options...
jgkurz Posted July 10, 2003 Author Share Posted July 10, 2003 Lockjaw, If I remember correctly you have a JWT Sport 450. Correct? Thanks Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted July 10, 2003 Share Posted July 10, 2003 Yes, and it is a sweet turbo. I think I need more clutch to be honest, but time will tell. Let me give you some perspective. The 60 trim flows about 50 pounds per minute. if I remember correctly, the 60-1 flows 70, so that is a pretty big jump. There is nothing in between that I have seen yet, other then perhaps the new garrett wheels. I like the 60 trim, and have yet to reach its limits that I can tell. I just wish I had all this stuff in a 240z. Quote Link to comment Share on other sites More sharing options...
