Well since I am super cool what better way then to hustle people on the street/track with my lowly 'truck motor' packing 250 in a bottle. I am looking to find out realistically how much this setup will wear a motor done less than SUPER HIGH END PROFESSIONAL because I don't know if that is an option. I seem to recall Aries having a Nitrous KA with a 200 shot. (I believe, I may be remembering the wrong person) What compression, type of piston, any head work, extra injectors, ECU, etc if any did you use? I think it would be a good project that I could probably do a not bad job hooking up myself. And yes I know, some say Nitrous isn't FA, but oh well, i'm postin it up here.
Anyone who has done this, knows people, has heard stories, I just want to know what everyones and their friends expierences have been.
High Nitrous KA motors..tell me your stories/expierences
my old motor ran 9.0:1 Arias pistons with Eagle rods and bearings.The head had about $2500 worth of work in it, and the motor had all the bolt ons.If you're looking for power with a nitrous motor, DO NOT USE A JWT ECU! The JWT ECU will retard timing when programmed for a nitrous car to the point that there is simply no pull on the top end. It can also cause puddling and intake backfires on a wet shot.
If you're looking to go fast on nitrous, my suggestion(safest/most reliable) is a wet shot. I have almost always run dry shots on my own cars, but they get to spend lots of time on the dyno being tuned and jetted to just the point of detonation, and then backed down 1 pill size.

What type of head did the Arias pistons have (flat, scoop, etc), or does that even matter?
Would a piston not made of this heat resistant alloy be able to take the punishment?
For the head it basically sounds like you had to change EVERYTHING on it..because I don't even know how how you can get a $2500 bill on head work?
p00t: because I tried posting this in the FI forum where things like this are supposed to be addressed, but no one goes there and some dont consider Nitrous FI..so the thread gets 3 new living spaces.

I have a guy up in phoenix I'm talking to right now telling me was running a 200 ("give or take 30 either way") DRY shot on completly stock everything KA24DE. Injectors, Fuel Pump, Pistons, Rings, Rods, Head, EVERYTHING STOCK. I called BS on him, but he claims it was all stock, and he only did it because he already had his hands on an SR whenever he wanted and he had the money (works for a perfomance shop up there), and the setup lasted him 30 bottles, he was amazed at that, but in the end, he thought his pressure gauge was broken, but it wasn't, so when the needle spun all the way around he kept doing and kaboom. A sad end, but does this sound plausable? It sounds to me like with a little work a KA should be able to handle 200 without keeling over like a canary in a coal mine, but what do you think about that?

there is no way he was doing that on a stock fuel system.and about the needle on a pressure gauge... BS!The gauge goes from 0-1600. No more.And at 2000 the bottle will burst the safety release in the neck (had one go off in my trunk). The needles do not move all the way arround, no do they move up while the nitrous is in use.
This is some kid thinking he's a badass.

Aside from getting a Gude head, what could be done to it to make it more ready for this type of spray, on a dry shot, because I've heard wet shots can more easily lead to a backfire in the intake manifold...isn't that how your's got killed though?
Is there going to be a problem running a more aggressive cam with nitrous?
Will the ECU be able to compensate all the way up to the 200 shot, with the proper injectors and pumps?

the stock computer will easily compensate with the correct fuel system.
My motor actually died because of an injector failure. I prefer a dry shot over a wet shot, and that was my downfall. LOL. But yes, a wet shot can pool gasoline in the intake plenum/runners and cause an intake backfire destroying the MAF/MAP and sometimes even the plenum itself.
