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.

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
