sims76 Posted April 19, 2005 Share Posted April 19, 2005 Right now I'm running my recent turbo setup at 12PSI and the stock 240MM clutch/pp is slipping like crazy in 1st and 2nd gear if I nail it and also at the top of 3rd. I read all of Jersey's, Bastaad's, and Moby's posts and decided to order an ACT Clutch setup from Courtesy Nissan. "ACT Clutch Kit w/ HD Pressure Plate and Modified Street Disc 79-86 ZX Turbo" Right now I'm running a 3.90 rear. I put this in when I was NA. Should I put my 3.54 rear back in there now that I am running a turbo setup?????? Any comments welcome. I'm also going to the local Dynojet next week, wish me luck. Just for fun, here are datalogs with no clutch slip and with the clutch slipping. NO SLIP SLIPPING BAD Quote Link to comment Share on other sites More sharing options...
Drax240z Posted April 19, 2005 Share Posted April 19, 2005 Most data gathered over the years suggests that a 3.54:1 rear is faster in a turbo car than the same car with a 3.9:1. Verified in some old thread here many moons ago with timeslips, feel free to search around for it. Quote Link to comment Share on other sites More sharing options...
BayAreaZT Posted April 19, 2005 Share Posted April 19, 2005 Never tried a 3.90 rear but I switched from a 4.11 to 3.54 and was much happier. Couldn't build much boost in 1st gear. Gearing for the freeway was a lot better too. ACT clutch grabs really good. Clutch feel is pretty heavy but you get used to it. Quote Link to comment Share on other sites More sharing options...
