I have searched and cannot find any drop in injectors in the 650-750 size range. Any help would be appreciated.

I know some people run the RC550cc's (w/modified harness) and I heard SGP use a 720? which one?

 

phunk (Charles) is using HKS 1000cc fuel injectors. I think overboost.com might have them, or just pm him and ask him where he got his.

 

I did see that phunk uses the HKS 1000cc injectors, but he also uses the spacers provided in the Greddy TT kit, harness (RC style), and has to do some machining... I am looking for a direct swap if possible. Thanks for the tip though!

BTW, I am not afraid of a little machining or to run a spacer or to change the harness or clips... if it was just for a one off application (or my own car...) But I am looking for a more viable drop in without having to do all of the above for production purposes. TIA for any tips!

 

HKS 1000cc injectors use stock 350z injector clips

They are, however, very low impedence... if thats a problem for you.

As for the spacers, simply longer bolts with some plastic spacers available at a hardware store would work fine.

As for the lathe work we did to them, that was simply to machine the O-Ring groove thicker so I could use a thick enough O-Ring to make their smaller tips seal in the larger diameter orifice in the stock or stock replacement (AAM) rails.

1000cc will be impossible to control well without a standalone.

As for where I got them... from me of course. I am one of the exclusive HKS Prodealers which is how I was the first to run the FCON in a stateside 350z with some help from Jon at HKS.

PM me if you need me to machine the injectors to fit for you. Once they are machined they are a simply plug in fit with only spacers being the big deal and I could supply them also... they plug right in otherwise.

 

Thanks for the clarification Phunk. I will contact you if I can't find anything closer to my target size... any other recommendations for something in the 650-750 range?

 

not of the drop in variety. You can do larger PE injectors which are drop in and plug and play. 510cc is as large as they go...to my knowledge.
