Thats a pic of standard injector seated in manifold.Screenshot_20180122-174707.thumb.png.068ceb99a81f538477dbc3e0d8547949.png

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

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.

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?

Can we get you to measure the size of that water hole please

Cheers A . 

Does that top water passage have any requirement other than being a source point for other components?

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

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.

    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
    • Probably. I take it that they are also mentioned to be for R34 Skyline? For example.... RDA has that part as RDA7957. I have the dimpled and slotted version of that on my car https://www.ebay.com.au/itm/285518478694?srsltid=AfmBOopKxMuAFpsxZJdB1cam4D5RAj1f9yJyOttPZLAwXVNCOiwlhrIy This is DBA's top one piece equivalent https://www.ebay.com.au/itm/364246686631?srsltid=AfmBOorbb0XHQgqTvZLgQPhg70nqJtGvdojKnugum3O2LFSr2h-obp8D
