I had it on my 1st gen eclipse and loved it! You just have to make sure if you have it tuned with the water/alcohol that it always has some in the tank! I had a warning light hooked up to mine to tell me when the tank was getting low. Almost all the rally cars have it on them.

This is a good cheap kit, and it has the same pump as the expensive kits. I have installed this kit in my car and it works well, I only use water and it keeps the detonation levels right down.

Fairly easy to install only problem is space, because the pump is huge and you still need a big water tank so you're not filling up all the time. What I did was made up a bracket and mounted the pump beside the the factory washer tank.

mate, a WMI failure can destroy an engine in seconds, I don't know if I would trust something like this.

Is it a sureflow pump?

Also, pressure switches aren't that good, because your spraying the same amount of water in at 3,000rpm as you are at 7000rpm, and since there is a lot of water going in at low revs, the car can shudder. I like the idea of variable water, brings it in nice and smooth, you'll use a hell of a lot less water\meth too.

Kits are only $600 now, and if you can' afford a kit at $600, why are you chasing the power, or even own a skyline? Sounds harsh, and I apologise, but saving a few hundred on a cheap unknown kit could cost you well into $4,000 on a engine rebuild?

agreed, with injection you are always treading a fine line. Best to use better gear for peace of mind.

i havent used it for about 10 years though.

would be a waste of time - you'd probably lose performance because you can't advance the timing in a factory ECU.

Just for those that don't know - You don't get any performance gains for just installing the kit itself. You need to be able to advance the timing to get the extra power.

Yep sureflow pump, looks exactly the same as yours.

I agree variable water injection is the way to go, you buy this kit and get a variable injection module for $50 and save yourself a few hundred against the over inflated aus company prices. I just don't see the point in spending more for the same thing.

I had mine setup with the pressure switch that only came on at full boost, it was also tuned to compensate for excess water provided at lower revs. I also used a small nozzle which had little no effect high rpm but stopped a lot of the knock I was getting in mid-revs.

So it's not the best setup but in practice it works well. I wasn't really aiming for more power like your setup just better cooling reliability as my intercooler struggles at times with the type M front bar covering it up.

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
