Any sugestions about a good source for a set of standard injectors for a 1990 NA would be a great help. Dave
I was looking for a new set a month or two ago and there wasn't really anything available in australia. Coz in the US was the best solution at about $134USD ea... http://www.conceptzperformance.com/...Type=NIS300&UID=20071103140917220.233.118.234 Cheers, Dave.
ive got a spare set they had been cleaned and flow tested last year and we fine if your interested let me know they would only need another clean.
Definately take up AZA's offer on those second hand injectors, if they're good then they're good. It's not really logical to spend almost $1,000 replacing stock injectors in my opinion unless the car simply must stay stock and you cant find any cheaper second hand. You can buy some big ass aftermarket injectors for the same price as stock replacements...
With all the effort to replace the injectors with a plenum pull etc, I don't see the point of putting in 2nd hand ones that would probably be 17 years old and may fail electrically any day..They wouldn't be any better than the ones you already have. I have had 2 of my injectors fail by going open circuit.. No amount of cleaning will prevent that. I wouldn't bother with upgraded injectors from the stock size on an NA.. It's not like you can up the boost.. And the hassle of getting the ECU remapped to suit just isn't cost effective for the zero gain you'll get. Look around Aus for a new set of injectors but I couldn't get any locally. Use 2nd hand ones if you can get 'em cheap and you don't mind replacing them when each one fails. I'll be getting a full set from Coz and replace them all at once. Do the job once and do it properly. Happy Zedding! Cheers, Dave.
Surely Z32 injectors aren't that shit? I've got 20 year old injectors still going strong in my Z31s...
You wouldn't think there would be too much of a problem with 'em but I have had 2 fail and a 3rd that is on it's way out. They are affected heat, ie when they get hot they open circuit and stop working until they cool down again. May be just an NA issue though. Heat affected electrical components in a Zed isn't too uncommon though.. Cheers, Dave.
i've got a set for sale - cheap as i've got a set you can have for $50, theres nothing wrong with them, i'm just never going to need injectors ever again. (lpg conv) cheers scotty 0421634530 raveale@optusnet.com.au
Interesting that the injector thats failed hasnt gone open circuit. All the others read about 12 ohms. The crook one reads 70 ohms. Has anyone seen this B4? Dave
Sorry to hijack but if you were to upgrade the injectors, what would cc's would you upgrade to? Thats assuming you got a ecu remap ect ect 320cc? 350cc, just out of curiosity... or maybe more :zlove: PM sent chrispy
For a stock NA I wouldnt bother, there's lots of work to be done before more fuel is going to be needed for an NA motor. My head was in the clouds when I suggested to look at upgrading instead of paying top dollar for new oem ones. I forgot he had an NA...
For a super dooper crazy NA, you could go for TT injectors, they are 370's and more than enough to support over 250rwkw.
