discopotato03 Posted January 22, 2018 Share Posted January 22, 2018 Sorry people bum steer . Standard the R34GTt injectors tips are not that close to the manifold face after all .

NEO25T Posted January 22, 2018 Share Posted January 22, 2018 Thats a pic of standard injector seated in manifold. Do you think there would be any gains to try and make the injectors sit here compared to where they are sitting with the spacer installed which is approximately 8mm further out. I would assume we could just drill the injector hole a little to let the spacer go further down. When i get a chance ill have a go and see what happens lol 1 Link to comment https://www.sau.com.au/forums/topic/472924-issues-fitting-12-height-injectors-1300-1550-1700-2000-etc-with-extenders-to-rb25-neo-intake-manifolds/page/3/#findComment-7865778 Share on other sites More sharing options...
Dose Pipe Sutututu Posted January 22, 2018 Author Share Posted January 22, 2018 I believe the 1550cc aka 1650cc (at 4bar) are more so a pencil stream injector so it wouldn't matter too much. I've tried to look for spray pattern videos or photos but didn't find any solid evidence of the spray pattern. In saying all this, I can safely say the 1550cc Bosch injectors actually run very well, dare say better than my old 875cc Siemen DEKA V (stainless shorties). However many variables such as an old tired motor, non NEO head and stock vs non stock parts. Still same ECU. 1 Link to comment https://www.sau.com.au/forums/topic/472924-issues-fitting-12-height-injectors-1300-1550-1700-2000-etc-with-extenders-to-rb25-neo-intake-manifolds/page/3/#findComment-7865797 Share on other sites More sharing options...
iruvyouskyrine Posted January 25, 2018 Share Posted January 25, 2018 Johnny you have been talking about the 'jetski' injectors which I believe are the 930cc bosch units ending in 040 correct? You're well would these work on RB26 with the extended tips?

discopotato03 Posted January 28, 2018 Share Posted January 28, 2018 There are some drillings in the Neo manifolds water passages but I can't remember where and I don't have one to look at ATM . A .

On inspection, purely to cool the upper area of the manifold, provide water to the bleeder and the turbo. You could go without feeding it any water and deleting the bleeder and sourcing the water elsewhere Link to comment https://www.sau.com.au/forums/topic/472924-issues-fitting-12-height-injectors-1300-1550-1700-2000-etc-with-extenders-to-rb25-neo-intake-manifolds/page/3/#findComment-7867700 Share on other sites More sharing options...

You could go without feeding it any water and deleting the bleeder and sourcing the water elsewhere Ill have a better look at it later this week but im sure you can basically cut that top part off and just keep, how do i explain it, like 2 posts where the rail bolts down. Then screw or weld dash fittings in to the water points you require as they will still be accessable. Bit of stuffing around to fit injectors but for people that have nothing better to do it might be an option.
