blech... I thought J32's had forged internals (or so I read in another post here), I guess somethign was seriously wrong there, or the forged internals are a lie.
do the other cylendar s have white scaring like that?

(55 shot dry), ford fairmont v8 (150 wet), civic (55 dry) have never had a problem except for burning out plugs quickly. Honestly I think NOS is the best HP for the buck. Just as long as it is installed properly and all necessary precautions are taken. In my case, I think that using an unmarked jet from a friend who CLAIMS it was a 75 shot was the biggest X factor and stupid mistake in my failure

It has nothing to do with having nitrous. That could happen with supercharger or turbo if it doesn't have the correct a/f ratio. Nitrous itself won't do it but incorrect a/f will mess it up. I had nitrous on my car for over a year and used at least 10 bottles w/ no tranny problems and/or engine problems on my TL.

Just look at Mattg's old set-up and how much power he was putting down. Although I believe he went through a tranny, but so did plenty of non-boosted members.

i said this in your other post a while ago" i can't believe you didn't put a hole through the pistons with it running so lean, yeah do the compression test and also do a leak down test please. i would think you would have at least destroyed the pistons rings, does the oil smell like gas, if you they might be bad because with them holding no compression the fuel is washing down the cylinder walls into the oil. i mean you melted the ground electrodes, that is something to be proud of i have not seen to many cars do that. i would try taking to a place that has a small cameras that you can use to inspect the cylinders, it a really small camera and it goes in through the spark plug holes and you can inspect the piston tops, the cylinder walls and if the have one that moves you can inspect the cylinder head too, that is if it gets to that point of needed to do that."
i think i was right, as you can see it happened on the exhaust side, that means there was a ton of heat on that side, looks like that's where it found the weakest part of the piston, also maybe on the of the spark plug prongs was resting right there and got so hot that it created the detonation(spark knock) in the piston. also check out the white specs, that looks like its parts of the spark plug.

That's detonation.... scuffing on one side means combustion occured while the piston was still on its way up - it moves to the side - looks like the 'burn' in the j32A2 puts more force on the exhaust-side - maybe shaping the piston better will help?!?

I think Matt is still trying to sell the UniChip... might want to check on that.

The Zex kit includes some kind of pressure inhibitor which I think is powered by the pressure of the nitrous which increases fuel pressure by means of integration into the stock FP regulator. I've seen my pressure increase to over 15 psi compared to stock max.
40@idle, 50@max and 65 w/Zex activated w/full bottle.
I have my doubts that it is enough but it supposedly is a good enough increase to handle a 75 shot jet.
But like I said, the unmarked jet could have been a 150 (or more???) for all I know which would definitely have caused major damage after running 1 complete bottle and 1 run of the full pressure of the newly filled bottle.
If I do decide to add NOS again, I will definitely get something to custom tune my engine since I will probably need it anyway with the 3.5 upgrade. What do you think? Think it'll run fine n/a w/o custom tuning? I don't have the money now for an emanage now, but if it'll help out a lot, I'll save up for it in the future.
