You can run injector cleaner thru them but when there cleaned professionally they are ultrasonically cleaned I'm not 100% on the process but you could not do the same job at home you maybe able to get someone ( mobile bloke ) to come out and clean them but still would be fairly pricey I would assume

On the cheap you could try taking them to someone with a jewelry ultrasonic cleaner, though I'm not sure how effective they would be on injectors. Profesionally done they use a proper ultrasonic cleaning bench designed for injectors and have them flow tested and even balanced if the person is good. As far as bottles of injector cleaner go my experience and people who I've talked to who work in the auto trade say they don't do anything significant for their price (some bottle cleaners arent O2 sensor safe for example).

I think getting injectors done professionally is pretty cheap when you do the labour yourself and R&R them, I vagually remember a mobile guy out in WA that people on here have sent their injectors interstate as even with postage its still cheaper than people in their own state.

I was quoted between $150-200 for a mobile guy to come out and ultrasonically clean my injectors (as long as I pulled the rail out prior)

Maybe another $50-100ish if he had to pull the rail out too.

The only thing I would run through my injectors is fuel doctor it's an independent company dedicated to fuel additives don't no I they are outside of qld but a good mate of mine works there and I have used it my self and was very impressed with it I it's designed to clean injectors and fuel systems as well as removing built up carbon deposits I had a set of platnuims out of my old 32 and they were all caked with carbon so I put them in my car when I ran some doctor thru to see if it actually worked pulled them out a week or so later and they were clean as I was shocked lol and fuel economy was better it's good stuff

My 2 cents anyways

The other advantage to having them done professionly is to flow test them at the same time to ensure all are withn 3% of each other.

then fit the ones that flow the most (if any) to the leaner cylinders, on an rb26 thats #6 then #5

i assume that the same applies for an rb25? the back 2 cylinders (next to the firewall) are the leanest ?

    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
    • You don't have an R34 service manual for the body do you? Have found plenty for the engine and drivetrain but nothing else
    • If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.
    • Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)
