simple monkey Posted July 8, 2007 Share Posted July 8, 2007 I'm finally looking into upgrading my injectors, but i have a few questions. I've searched and searched, and the 280zx turbo injectors seem to be a good candidate. But, there are none in the local yards, and injectors seem hard to come by. So, as an alternative, i've found that stock volvo injectors come in 2 sizes: 357= the bosch 357 injectors that came stock in the 84-89 b230ft motor 29lb/hr (300cc/min) @ 3bar 804= the bosch 804 injectors that came stock in the 90+ b230ft rated 30lb/hr(310cc/min) @ 3 bar i plan on using an S-AFC or e-manage to tune the bigger injectors, but is there anything else i should have to look out for?

GLCraig Posted July 8, 2007 Share Posted July 8, 2007 you need to make sure that those injectors have the same or very close to the same electrical impedance as the stock injectors. Quote Link to comment Share on other sites More sharing options...

Could you please be so kinda as to make more clear what vehicles/engines these Volvo injectors are sourced from??? I am a datsun guy, and I need bigger fuel injectors for my (to be turbo) 280Z.. I am striving to source as many parts from the JY as possible, and there are OODLES of volvos around. EDIT didnt think much before I posted that; as I was re reading it a post in my Z-car forum came to mind, and i went and hunted it down. (Naturally, it was absurdly easy to find, making it even more embarassing that I asked such a simple question.) http://forums.hybridz.org/showthread.php?t=118512 First post in the thread, a little more than a page down.. "Here is a good page for more information with flow ratings of other injectors. http://carsoft.co.il/page3/Electronic%20Fuel%20Injector%28EFI%29%20Flow%20Data%20Table.htm http://www.witchhunter.com/injectordata1.htm http://www.atlanticz.ca/zclub/techtips/injectors/injectors.pdf " GO READ the thread, there is much more info.. further down just in that one post alone... but between the pdf file in the third link, and the table in the first link, ALOT of information should become available.

simple monkey Posted July 9, 2007 Author Share Posted July 9, 2007 these volvo ones i'm interested in are high impedence. i'm assuming we have low impedence injectors, correct? when used on the N/A volvos, they require 4 x 10ohm resistors wired into the AFM. has anyone ever tried this before? glcraigGT, thanks for the response. i'm glad you brought up the impedence values early tho, might have forgotten about that........
