NissanSportMag(Z31) Posted December 5, 2006 Share Posted December 5, 2006 DET wiring is completely different from ET wiring. You won't be able to use your stock ET wiring with the DET. At least, not without a lot of modifications. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted December 6, 2006 Share Posted December 6, 2006 My friend was going to put a DET into a 280Z and talked to JWT about ecu setups. JWT told him they've messed with them before and had good success using a VG30DE ecu and wiring harness (tuning the ecu for boost of course). That would likely be your best bet.

nismopu Posted December 8, 2006 Share Posted December 8, 2006 why did you take out the vg30et? Quote Link to comment Share on other sites More sharing options...
Guest blackbox Posted December 8, 2006 Share Posted December 8, 2006 the bottom end was shot and i wanted a JDM motor so this is what i got Quote Link to comment Share on other sites More sharing options...
NissanSportMag(Z31) Posted December 8, 2006 Share Posted December 8, 2006 the bottom end was shot and i wanted a JDM motor so this is what i got That's a VG30ET motor, not a VG30DET. The "D" in the term means it's a dual overhead cam motor. With no designation before the "E" (electronic fuel injection), the motor is a single overhead cam motor.

Guest blackbox Posted December 8, 2006 Share Posted December 8, 2006 so this isnt a JDM motor? Quote Link to comment Share on other sites More sharing options...
NissanSportMag(Z31) Posted December 8, 2006 Share Posted December 8, 2006 Yes, it is a JDM motor. No other Nissan in the US had a VG30ET. Quote Link to comment Share on other sites More sharing options...
Guest ZbeGON Posted December 10, 2006 Share Posted December 10, 2006 The motor pictured above is JDM, but the setup (intake) was also used on the 88'-92 maximas here in the U.S. The only differance was they bolted turbos on the JDM versions, which would have been the Leopard and Gloria in Japan. They used side feed injectors which are harder to upgrade than the topfeed that was on the 84-85 turbo Zs, 86-89s had duel side/top feed injectors. I have the same motor with the USDM intake on top.

mtcookson Posted December 11, 2006 Share Posted December 11, 2006 Yup, definitely JDM VG30ET (not that I had to confirm it or anything ). I have one in my Maxima but with the Maxima intake elbow (pipe right before the throttle bodies). 8.3:1 compression, T25 turbo, euro cams, no egr, and I believe that's it for differences. They only came with an auto tranny but all the manual tranny stuff swaps right over of course. Quote Link to comment Share on other sites More sharing options...

NissanSportMag(Z31) Posted December 12, 2006 Share Posted December 12, 2006 Is there a spot on the JDM head for where it goes? Look for plugs at different locations and see if the CHTS will screw into any of those places. Quote Link to comment Share on other sites More sharing options...
Guest blackbox Posted December 13, 2006 Share Posted December 13, 2006 i found it on the driverside of the intake manifold. Quote Link to comment Share on other sites More sharing options...
