jayzrocket Posted May 8, 2009 Share Posted May 8, 2009 I need a little direction pleeze. I have a mostlty stock zxt w/ a few minor mods. Fresh T-3, 10lb cotroller, Blitz bov from 180sx, decent intake w/ 60mm tb, adjustable fpr, and just purchased an 11mm o-ring fuel rail. I was wondering if anyone here has any suggestions for which injectors to use w/ the factory ecu? The gentelman that I bought the rail from said that the yellow top supras would be fine, but I remeber reading in the fuel injector upgrade opions tread that to steer clear of them because of the cc rating. Maybe these would be ok with the fact ecu. And shouldn't I stick w/ low impedence? And are the yellows Hi or Low's? Thanks in advance, J.

junglist Posted May 8, 2009 Share Posted May 8, 2009 You could try running some Mitsubishi Eclipse injectors, RX-7 or some of the Supra injectors. Here is some info for you: Eclipse injectors: Non-Turbo 1.8L - N210H Injectors-casting #INP-057 (210cc High Impedance) Non-Turbo 4G63 - N240H Injectors-casting #INP-059 (240cc High Impedance) Turbo 4G63 A/T - B390L Injectors-casting #INP-008 (390cc Low Impedance) Turbo 4G63 M/T - B450L Injectors-casting #INP-009 (450cc Low Impedance) 2G Turbo BlackTops -MDL450 casting #IPN-081 (450cc Low Impedance) 2.4 - MDH275-casting #IPN-065 (275cc High Impedance) http://www.lextreme.com/rx7injectors.html - RX-7 injectors info This page has some good injector info, all these are sold as reconditioned and he sells some Z stuff specifically: http://osidetiger.com/reconditionedinjectors.aspx Quote Link to comment Share on other sites More sharing options...

aziza z Posted May 9, 2009 Share Posted May 9, 2009 I got Ford lightning injectors. 440ccs for sale. They fit stock fuel rail. Link here. http://forums.hybridz.org/showthread.php?t=146486 Quote Link to comment Share on other sites More sharing options...
jayzrocket Posted May 11, 2009 Author Share Posted May 11, 2009 Lookin' for o-ringers, thanks. Quote Link to comment Share on other sites More sharing options...
aziza z Posted May 12, 2009 Share Posted May 12, 2009 Those are o ring type injectors. I meant to say they fit the stock intake not stock fuel rail. Pics in the thread. Quote Link to comment Share on other sites More sharing options...
jayzrocket Posted May 12, 2009 Author Share Posted May 12, 2009 11mm? And shouldn't I use low impedence with turbo and factory ecu? Quote Link to comment Share on other sites More sharing options...
adamhoud Posted May 12, 2009 Share Posted May 12, 2009 When would you use high impedance? What would be preferred for when running megasquirt? Quote Link to comment Share on other sites More sharing options...
aziza z Posted May 12, 2009 Share Posted May 12, 2009 11mm? And shouldn't I use low impedence with turbo and factory ecu? I believe they are 11mm. But I know they are High impedence. They were used with a megasquirt setup. Quote Link to comment Share on other sites More sharing options...
jayzrocket Posted May 13, 2009 Author Share Posted May 13, 2009 Dig it, but I think ima go in a different direction for now. Thanks for the input but Iv'e gotta go with the lows. Quote Link to comment Share on other sites More sharing options...
Comrade_Charlie Posted May 13, 2009 Share Posted May 13, 2009 If your ecu runs low impedance injectors, you can use high imp. injectors with a low imp. ecu, you cannot use low impedance with high imp. ecu, unless you use drop resisters. Im running ford probe injectors(324cc high impedance), on my low impedance z31 ecu. single cam 240sx injectors are 260cc and o ring, stock l28et injectors are 270cc, if you want to stay relatively stock, to keep from tuning.

adamhoud Posted May 13, 2009 Share Posted May 13, 2009 Is megasquirt designed for low or high impedance injectors? Quote Link to comment Share on other sites More sharing options...
aziza z Posted May 13, 2009 Share Posted May 13, 2009 Is megasquirt designed for low or high impedance injectors? Either or. There is a setting in it to change injector characteristics (At least MSII you can do that anyway). Quote Link to comment Share on other sites More sharing options...
adamhoud Posted May 13, 2009 Share Posted May 13, 2009 Is one better than the other? Quote Link to comment Share on other sites More sharing options...
zatsun Posted December 28, 2009 Share Posted December 28, 2009 If your ecu runs low impedance injectors, you can use high imp. injectors with a low imp. ecu, you cannot use low impedance with high imp. ecu, unless you use drop resisters. Backing up the truck here...really? Can anyone else confirm this? If so, I would reckon the Eclipse 210cc injectors will work for my stock L28..
