BluDestiny Posted December 16, 2009 Share Posted December 16, 2009 I know everyone tends to do teh e12-80 dizzy from the later model z's and zx's and also the crane/petronix upgrades to solid point What else is out there? I want something that will rev all the way to 8k with no problem. For some reason, my car kept dying out at 5500 on the dyno today. AFR was good and fuel pressure was good, leads me to believe spark may be the answer to higher reving. Engine dynoed was a stock 260z with the stock distributor. found this from google search: http://www.zcar.com/forums/read/1/1857836 Quote Link to comment Share on other sites More sharing options...
Zmanco Posted December 16, 2009 Share Posted December 16, 2009 I want something that will rev all the way to 8k with no problem.What are your plans for other engine mods? This comment sounds like you have ambitious plans for the engine in which case you should probably skip those options and go straight to something like EDIS. I doubt the Crane is rated to 8k and am pretty sure the pertronix is not. At 8k rpm there isn't enough time to fully charge a typical coil if it's driving all 6 plugs. For some reason, my car kept dying out at 5500 on the dyno today. AFR was good and fuel pressure was good, leads me to believe spark may be the answer to higher reving.Is this with stock points? Quite possible they are starting to float. I rode with a friend who has a 260z with a nice cam and triple webers but stock points which acted as a rev limiter every time he would get near 6k rpm.

Mikez31ss Posted December 16, 2009 Share Posted December 16, 2009 From recent personal experience I can tell you there is a lot more info than that out there. Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted December 16, 2009 Author Share Posted December 16, 2009 The motor is being built currently. Pretty much stock bottom end, but the head is port/polished, stage 4 MSA cam, triple webers, and headers. Also the MSA Alum radiator. E88 head on a L28 bottom It is stock points, I know I need to upgrade to electrical ignition as I'm probably being limited by the points dizzy Quote Link to comment Share on other sites More sharing options...
Zmanco Posted December 16, 2009 Share Posted December 16, 2009 At 8k rpm on an L6 there is only 2.5 ms available for each complete ignition cycle (charge + discharge coil). Have you looked at other methods such as EDIS? Quote Link to comment Share on other sites More sharing options...
Administrators RTz Posted December 16, 2009 Administrators Share Posted December 16, 2009 An 8k motor deserves more than a distributor. EDIS... Hombrew... Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 16, 2009 Share Posted December 16, 2009 ^^Agreed. Distributors are inherently inaccurate. Don't use one if you're going to spin the engine up that high. Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted December 16, 2009 Author Share Posted December 16, 2009 Thanks guys, how are they implemented? I saw a thread in the vendors forum, but I don't understand how they are wired in. Quote Link to comment Share on other sites More sharing options...
sickboy Posted December 16, 2009 Share Posted December 16, 2009 +1 more, no distributor at 8k. Start reading here: http://forums.hybridz.org/showthread.php?t=113165 Quote Link to comment Share on other sites More sharing options...
