Domzs Posted July 18, 2013 Share Posted July 18, 2013 78 Z was done in Jan 13 , has about 500 miles . Broke front diff mount , converted to RT diff mount . Now I have to redo my motor/trans mounts , RT diff mount threw drivetrain angle off a little ( vibration ) . 83 was done about 2 or 3 yrs ago , rear diff is clunking . Will be converting to solid axle once the turbo 6.0 is built . Quote Link to comment Share on other sites More sharing options...
78zstyle Posted July 18, 2013 Share Posted July 18, 2013 The rear end issues make me happier I'm going automatic. I can't imagine what its like to have to worry about breaking your half shafts all the time Quote Link to comment Share on other sites More sharing options...

PLATA Posted July 21, 2013 Author Share Posted July 21, 2013 (edited) The intent/purpose of this thread is to update members with information on LS1 Z conversions. I as an owner of one would like to know on any improvements that can enhance the performance( suspension,exhaust,brakes, transmission / differential, electrical components/ECU ),reliability,latest on maintenance tips , overall upkeep on a Z and the developments on the built. It come as a surprise that less than five site members have shared their info, if this is a duplicate thread please link it or if this a worthless topic delete it Edited July 21, 2013 by PLATA Quote Link to comment Share on other sites More sharing options...
NgoZ Posted July 21, 2013 Share Posted July 21, 2013 I appreciate your effort of sharing information. I for one will be doing a conversion in about a year and been saving and documenting information as I find relevant to my LS1 conversion. I find some of the headaches and fixes of others interesting in seeing the cause and solutions if I ever run into them.Thanks again!!

CrayZ Posted July 21, 2013 Share Posted July 21, 2013 DomZ what front diff mount did you destroy? Quote Link to comment Share on other sites More sharing options...
Phantom Posted July 28, 2013 Share Posted July 28, 2013 I have 34,000 miles on my conversion so far with the following issues: 1. Infant mortality on the relays for my stock Z28 donor cooling fans. Replaced both and no issues in last 10 years. 2. Burned through a lead to my starter. Relocated it further from the exhaust header. No issues in last 8 years. 3. Smoked my front brakes while racing at Texas Motor Speedway. Replaced front brakes with Willwood 4 piston calipers on 12.2" vented rotors and rears with the 240SX calipers on 11.4" 300ZX rotors. Still need to add the adjustable pro portioning valve but otherwise no issues in 9 years. 4. Broke a half-shaft universal joint on a 1-2 shift at a track which took out my parking brake and brake caliper on the drivers side. Replace 30 year old parts and no issues since then. 5. Stock clock doesn't work - probably never will. 6. Developed a pinhole leak in my modified 280Z radiator. Had it repaired and no issues with it since then BUT 7. Had to replace my LS1 thermostat because solder from the radiator repair got in it and screwed it up. Quote Link to comment Share on other sites More sharing options...
