Hi guys,

My r33 is currently at the tuners getting things together and was also going to have the water meth injection kit installed. However, the tuner has said he is recommending against it as they have had experiences of people on the track with water/meth kits that give the car a shudder mostly when decelerating. My understanding would be that because it is a progressive spray based off boost that it shouldnt be issues like this as long as it was tuned for this?

What do you guys think? Should or should I not have it installed and tuned with the injection kit?

Ps it is a stage 2 kit from snow performance.

As said there is no problem on a properly setup system.

If your tuner has already had issues with one they setup then I wouldn't let them set yours up. Unless they simply had issues tuning someone else's dud setup.

if you have your check valve close as possible to the nozzle you should be good.

I had Meth then I saw the error of my ways, and saw the light and it is called E85, Praise be the Corn Overlords.

    • If you mean the alarm immobiliser; theyre internal to the alarm itself which makes that difficult; I couldnt even see where he put it; its not in the same place as last time; but with all black wiring it might be very challenging to trace  I had someone turn the key for me as I know it only primes for a couple of seconds As my post above; I am getting no voltage to the pump at all; but I am testing continuity of the power line (SB) from the pump plug to the relay fine. As well as the negative from the pump plug to a 12V constant.    Yeah; he blammed the no start on a bad battery; said I needed to get a new battery and it'll start. Turns out the battery drained because the tail lights had been on for half the day during the install (the rubber cushion on the brake switch gave out while he was testing it as I have a picture of the car from that morning with the tail lights off..i've replaced that). The battery was turning over the engine just fine for a long time; but got low since lights were draining it so it was too low to test a start after he finished. I bought a new one on his advice...$250 wasted. My original battery charged up just fine and is healthy.    It was running perfectly fine when I messed up the old alarm (programmed out the remotes). He couldnt start it after removing the old alarm; my assumption is that when he unhooked it; he didnt bridge the circuit back when trying to start it. Its always been perfectly fine. The ECU swap and pump were 2 years ago. It's never missed a beat in that time. 
    • This is a big issue for me without the diff. I just have zero drive from the passenger side when drivers side has no traction. Bec's parents place has a crazy steep driveway with odd camber and I have never been able to get up. My bro-in-law's 130i with an (unknown brand) LSD gets up fine as does their dad's Hiace. My car stays at the bottom. We have other odd camber roads around here as we're elevated a bit and if it's raining I can get totally stuck around some hairpins. 
    • Yeah, I am super excited for this.
    • Was the car running before he touched the car?
