yeah i read all that cheers, signed up to the ford forums now so having a read thro it all.

whats the diff between the BA-BF deka's and the FG deka's? and which one do i need for the neo.

cheers

i have no idea about FG falcons................ seimens injectors are used as an upgrede not stock. ie Siemens have branded this injector DEKA. if you find any thing has changed let me know.

Well, thanks to urtwhistle for his hospitality yesterday, it seems all I have to do to fit my RB20 injectors (same would go for GTR injectors I guess), is machine the bosses down a bit on the manifold where the fuel rail bolts and change the manifold side o-rings on the injectors.

Actually.. just had a thought.. Chris, what length are those spacers you are using? I only checked against your seimens injectors and forgot you were spacing the rail.. if that's the case then I'll probably just need a smaller spacer (couple of washers) instead of machining the bosses on the manifold down..

yeah i got that much cheers. So you ran the BA-BF replacement deka's then im guessing? as theres two diff part numbers (and prices) for the BA-BF and FG series.

Sorry mate if i came across a little abrupt, i was just feeling a little frustrated at the time. (was agro cos i lost a 10mm socket for a few hours)

oh i see i never realised there could have been a difference. Yes i went BA turbo injectors. siemens/VDO p/n FI114961

No problems, your welcome to drop past any time. its good being able to put a face to the name. I'm currently using a 12mm spacer.

you may be able to use some gr10.9 washers as they tend to be a fair bit thicker then engineering washers. give me a yell if you run into any trouble. i may have some in the bolt rack at work.

if anybody wants a cheap set of the 80Lb (875cc) Dekas, ive got some for sale here (new).

Ok i'm interested in these injecters.

I have read the whole thread but most of it relates to the rb25 fuel rail.

Now what do I have to do to make these fit? 23MM spacer with a longer bolt and longer fuel hose? Just so the fuel rail sits abit higher up?

hey fella, i have no idea about RB26's but yes i stated [b]13MM[/b] I ended up grinding them back to about 11MM as there was a bit of extra play there that i didnt like.

and being a GTR you probly dont need to worry about the fuel hose. But thats somehting you might need to look into.

So the fuel rail just has to sit higher? Thats it? The injecters that I looked at are top feed as well.

exactly and change the injector plugs to suit. but due to it sitting higher you either have to mod the rail so you can actually get the rail on the injectors.

or take the top half of the plenum off install the injectors and rail un modified. as the rail only clashs when your posittioning the rail over the injectors.

What cc are stock Z33 injectors? Are they a great bolt on upgrade for the ER34?

To my knowledge there the same style but unsure of the stock CC. i highly doubt that they would put bigger injectors in a NA car though.

Hey guys,

Was just searching on this for a friedn and realised that I know a guy who was getting the injectors at a great price. The LS1 and XR6T use the same style injectors, so the LS1 style bolt in replacement Motron 60Lb injectors would also work right?

If so, these guys do eight (yes 8) Motron 60Lb injectors for US$379 so surely US$48 per injector + freight and then buying injector clips etc would make them affordable compared to the Siemens Deka ones?

Anyway, the link is HERE

siemens ones. not a whole heap of work really, needed to wire in new plugs and machine up some 12mm spacers to space the rail up. other then that its a bolt in swap.

oh and check out the tutorial section... i made a guide for it also.

so for e85 it currently boils down to);

nismo 740cc, can't find any.

deatschwerks $640 pp which is plug and play.

80LB SIEMENS DEKA INJECTORS for around $365 pp plus wiring harness and machining a 13mm spacer.

or ID1000's for $700 but some (lots?) mucking around to install

I had actually toyed with the idea of putting the R33 inlet runners on the Neo head and just using R33 side feeds on the stock rail....but I never got around to confirming the stud patterns matched up, anyone care to check it out?

I know this is an old post but I can confirm this works. I have an R34 neo motor with R33 intake, rail etc on it. You have to pull a stud out of each end of the head and replace it with the standard R33 bolt but it isn't exactly hard to do.

I did it as it meant doing the neo swap was completely painless, running all R32 gear (in an R32) sensors, ecu etc. Just chopped the ignitor off and wired the ecu direct to the R34 coils.

Easy as piss.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • 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.
