Just a heads up for anybody putting in Sard injectors.

I just finished fitting 550cc side feeds to the skyline, and incurred a few dramas.

the main problem was that the o-ring supplied on the injector was too small and leaked fuel when the ignition was switched on. It didnt actually leak out, it bloody poored out almost to the point of spraying!

Lessons learned.

1/ Make sure you pressurise the fuel rail before replacing the throttle body (stock plenum) as it is still possible to remove and check the injectors with just the fuel rail in place. (unfortunately I was under the impression that as I had purchased the injectors and collars from sard new - that all would be ok.

2/ Remove the sard o-rings and use the stock injector o-rings. They are alot fatter than the sard ones and they seal!

3/ To remove the stock injectors from the rail, if you twist the injector to free it a bit, then spray crc or similar - they still dont come out very easily. I ended up just tapping the pintle with a hammer and out they popped. Either that or be prepared to get really frustrated.

4/ It is so much easier to just pay someone else the $200 odd that it would have cost to get the job done.:mad:

5/ The power fc % correction for injectors works pretty bloody well:D Started up straight away, no smoke out the exhaust.

Hope this may be of help to anybody else thinking of doing these themselves.

Mine were a bit under 1K from greenline. Probably a bit cheaper now that the AUD is a bit stronger.

The injectors themselves flow really well, all less than 1% difference - I had them flow tested prior to fitting. In fact 5 were bloody close to identical flow, and one was just a poofteenth lower (0.5ml per 100ml on open flow)

INASNT, no I didnt hear, poor bugger, hope he is ok. Your order should be ok, as he passes the orders on to japan as soon as he gets them, if you are unsure, just contact the japan office.

MattR - I was really impressed by the flow of the injectors, so was the guy who did the testing. Am still waiting to get them tuned. It would have been so much easier if they fitted first time is all, or if I had a front facing plenum. Also, must admit I was a little dissapointed that the o-rings they supplied didnt fit properly.

From all accounts they are good injectors, and they arent hurting your figures any:D Just hope when all is fitted, I might be making similar power - only time will tell.

Hey guys, I've just got a set of Sard injectors for my GTR from greenline and they didn't come with o-rings at all.

Steve, you said you used the standard o-rings instead of the Sard ones as they are better?? I have bought a set of standard nissan o-rings which should fit the Sards as you guys have said. Maybe the side feed injectors come with the o-rings and the top feeds don't?

Anyway fingers crossed the standard ones fit the sards...

BTW who can flow test the injectors?

Cheers

The o-rings did come with the ones I got. The bottom o-ring, near the pintle fitted fine, it was just the top one that is supposed to seal between the collar and the fuel rail that was too thin. O-rings arent very expensive, only a couple of dollars each, but if you can fit the stockers, save a few dollars anyways.

If you find a fuel injection specialist they should be able to flow the injectors for you.

Thanks for the offer Dean, probably take you up on that one:) Hoping around the 300 mark at this stage - similar to MattR's. Depends on how well the turbo goes (a HKS 3037S 56T) and how the bottom end holds up. I have a few other plans too, which will include a bigger turbo, but they are way off at the moment.

N/A® I got them done by a place on little Rundle street, cant remember the name off the top of my head, got it written down somewhere.

they quoted me $5.50 per injector, but it ended up costing a bit more (55.00) as they had to set up the machine for them (apparently there are dozens of differnet size/shape side feed injectors) then they had to pulse them for some time as the initial tests flowed 5% apart, which they werent happy with. He put this down to being new, and sure enough when they had been run for about 20 mins, they came up almost all exactly the same, just under 1% out on one injector, and a poofteenth out on two of the others.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
