Don't even need to spray much to get the benefits, the alcohol component will keep things clean!

Could even skip the catch can.

A mate of mine did this. Unfortunately he neglected to periodically clean the injection nozzle, which being water/meth clagged up. The motor went fkn bang on account of detonating its brains out.

Ouch. Knowing my luck, this is probably what would happen. I think I'll just stick with the catch can idea.

Yeah well his thing is/was petrol. Anyway he now has a newly sleeved 2ZZ.

Ryco do a half decent catch can.

If you're using it as an additional thing to clean the intake, and still doing all the normal maintenance to the car, and the WMI isn't being used as something to allow you to push the engine harder, than the only way a clogged nozzle will kill your engine is if you neglect maintenance on it... Which really, that'd happen even if you didn't have a clogged nozzle.

But let's say you're purely using the WMI for additional cooling and primarily for cleaning, so if it did clog up you'll just end up with a dirty intake like how it is right now.

I wonder what the chances are of the nozzle getting stuck open and potentially hydrolocking the motor or bending a rod. 

Is that a thing or is there some sort of failsafe. How does a WMI system operate? I also wonder how triggering would be set up? Being a diesel, it's almost always on boost.

Controller triggers the pump, AEM kits you can dial in what boost pressure it starts to spray at.

So theoretically you could only make it kick in at say 1.5bar of boost only (as an example, please DYOR lol).

I usually DMOR but in this case I was hoping someone would spoon feed me. Thanks for the link Johnny 😉

As I understand, and Dose can confirm, the nozzle is just a spray nozzle, purely mechanical item.
Kind of like the nozzles for a garden misting system.

Then you turn the pump on to pump water in. Pretty darn hard for the pumps to then "jam on" with the way electronics are. More likely if it "jammed on" it'll be through the electronics driver failing internally with a short, and then typically they've shorted that way that they end up with power everywhere, and bam, fuse blows, and now pump is off within a split second anyway.

Got around to dumping and refilling the trans fluid again. 3 litres came out and I put roughly that amount back in. Unfortunately the fluid temp got a bit too hot for me to complete the procedure properly. I'll revisit it tomorrow morning at the correct temp and make sure it's not over/under filled.

Was just able to crawl under at that height. My stomach struggled for clearance but managed to squeeze in.

Re checked and topped off the trans fluid again yesterday morning with the oil temp at 40-45°C, was 60°C when I filled it the other day. It took an additional 1 litre in. In total around 6.6 litres came out but 8 litres went back in.

Either, it's lost 1.4 litres of fluid during it's 8 years or somewhere along the line it's been serviced and short filled due to procedure not being followed. I made sure for the final fill the car was totally level, a spirit level was used to confirm, lol. I can now sleep well, knowing that it's been done properly. Trans shifts great and a massive improvement over pre service behaviour.

It's funny you mention that.

While underneath, finishing up with the trans service, the engine mounts where inspected and the oily puss dribbling out of the driver's side mount confirms my suspicions. A slight vibration at idle has developed recently, pretty sure it started shortly after a launch event. You can't really feel it, it's more like a droney sound/frequency around the dash windscreen area. My OCD can't tolerate this for long though.

I had already spent some time looking around for mounts. Every supplier in Australia seemed to only have LH mounts. Ended up ordering Meyle branded mounts. 1 from Amazon UK and the other from eBay UK. Will be a while before they arrive. Gives me time to plan how to get it done. It's going to be a shit fight,  pretty tight down there but hopefully won't be too much drama.

Will need one of those top mount engine support/lift brace contraptions. Will have to order one of those too. Damn freaking Germans. 

And Dose, this doesn't have LC like the DSG Vag's do. You just turn the ESC off, stall it up on the converter conventionally, release and get pinned into the seat while it thrusts forward like a caged animal that's broken free.

You've got this car worked out well!

Sure quite a bit to change/service those cars, keeping you busy haha.

Hmm I've used it on the SQ5 one generation up from your one, which also uses the ZF box.

Not sure if this relates to yours, read a few posts down.

Yeah, there is a fair bit to do but there would be for just about any car with 150k on it, except of course 90's Nissan's, coz they're the best. To be honest, I just want to get this stuff done and then just enjoy driving it, knowing it's in the best shape it could possibly be in.

I watched that video in the thread you linked, that's exactly how mine launches without any silly launch control procedure. Just put it in S, ESC off, left foot hard on brake, mash accelerator and stall up on converter, release brake and hold on. They do get out of the hole very well, even without stalling it up.

Still waiting for engine mounts for the SQ5.

Skyline got a bit of love last week. Was back at chequered tuning for a check up after the turbo rebuild. All went well, was making power slightly earlier, with less boost and made more torque. Possibly due to the turbo being in better shape. Overall power was down by a couple of kw but pretty much the same. Didn't bother getting a graph, looked identical anyway. 

Also got him to look at a few things as I was getting a slight lean out on light acceleration and I'd noticed the ecu map sensor was not matching what my android dash was showing. In the past these values aligned. Turns out the ecu map sensor had gone out of calibration. Trent recalibrated it and that was fine. The slight lean out was also sorted, can't remember exactly what the cause was, he played with a heap of different stuff. Possibly a combination of the throttle cut and TPS calibration with a bit of adaptronic predictive map Async pump shenanigans. Either way drives nicer now. 

Also did a diff lockup check on the dyno and it passed with flying colours. There is a slight variance between wheels but as soon as a load is applied, locks up almost instantly with 0 variance. I asked for that check as I have traction issues. I guess the nearly 7 year old ado8r are very past their used by date now. 

Just about ready for a track day again but for some reason the driver can't find any motivation.

    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
