steve spedd Posted October 5, 2017 Share Posted October 5, 2017 Hi,  Looking to upgrade my 600cc injectors to 900cc or 1000cc as the current are nearly at their max duty cycle. My question is what do people suggest?  Asnu SARD Denso GRAMS  All around a similar price so just no idea on quality? any advice or recommendations greatly appreciated. It's for an NA-t but that doesn't really matter. Many thanks, Link to comment Share on other sites More sharing options...
Mike2JZ Posted October 5, 2017 Share Posted October 5, 2017 I've used a lot of injector dynamics injectors with great success so far. Whatever injector you choose, make sure the manufacturer supplies information regarding dead times, short pulse width adder etc. Link to comment Share on other sites More sharing options...
steve spedd Posted October 5, 2017 Author Share Posted October 5, 2017 Great thanks, I'd seen these but not had any experience with them: Â http://www.ebay.co.uk/itm/GRAMS-1000CC-FOR-TOYOTA-SUPRA-2JZ-NON-TURBO-INJECTOR-KIT-/401330617112?hash=item5d712b3b18:g:c9kAAOSwaEhZH2Xz Link to comment Share on other sites More sharing options...
Frank Bullitt Posted October 5, 2017 Share Posted October 5, 2017 (edited) Avoid GRAMS (because it's GRAMS), if you are looking for drop in injectors into an OEM fuel rail then SARD are the obvious possibly only choice. Just get them flow tested and the spray pattern checked before fitting them. Â I believe ASNU are linked to Bosch in some way, maybe rebranded(?). Edited October 5, 2017 by Frank Bullitt Grammar.

Lee P Posted October 6, 2017 Share Posted October 6, 2017 We use Asnu and they are very good, Bosch based injectors Link to comment Share on other sites More sharing options...
Wez Posted October 6, 2017 Share Posted October 6, 2017 If choosing from that list I would go ASNU Link to comment Share on other sites More sharing options...
phobos Posted October 6, 2017 Share Posted October 6, 2017 Injector Dynamics are also Bosch based. The advantage is that each set has matched flow rates, so no need to worry about any differences between each injector. Dead times over voltage can be found on their website.

steve spedd Posted October 6, 2017 Author Share Posted October 6, 2017 Thanks guys. Running Bosch at the minute so will go with the ASNU Link to comment Share on other sites More sharing options...
Guest Fastfish Posted October 6, 2017 Share Posted October 6, 2017 Why not just raise your fuel pressure slightly, or are you looking for big increases? Link to comment Share on other sites More sharing options...
steve spedd Posted October 6, 2017 Author Share Posted October 6, 2017 I'm afraid the 600's I have in are at 80% nearly (515hp) and I want 750hp ish. For this looking at the requirements I'll need 1000cc... Link to comment Share on other sites More sharing options...
Justin Bieber Posted October 6, 2017 Share Posted October 6, 2017 I would be interested in your injectors mate if you end up changing and they drop in a GE fuel rail? Link to comment Share on other sites More sharing options...
steve spedd Posted October 6, 2017 Author Share Posted October 6, 2017 I’m sure we could work something out. I’d be selling them and the emanage blue. When do you need them? Link to comment Share on other sites More sharing options...
