DAMM! I've never seen anything as bad as that! I'd love to know wtf happened there...

His pistons and valves came out his intake and exhaust!!!!

fuel and tuning are a must...

 

Lets see, you added 75 horsepower worth of extra oxygen and zero extra horsepower worth of fuel? Did you run colder plugs? gapped small? retard ignition timing?
I'm sure the sleeves could have held a lot more power than you were making, It's just the immense heat from running lean that killed your sleeve. I didn't think people actually ran nitrous without some sort of fuel compensation. I guess they do.

 

Hey That looks like the block thats sitting on the floor of my shop. Oh it is. Wassup dave. Listen, you guys who think this only happens to nitrous cars and thats why nitrous is bad. you gusy need to understand that id the kit is hooked up properly and the proper air and fuel mixtures are there it is the same risk as running turbo. trust me plenty of guys split sleeves with turbo. anyway, my guess is that the car came out of the hole bogged and he hit the switch and loaded the car up with spray w/o any load behind the car. then the tires ripped with an overload of N20 in the engine and the cylinder pressure was just too high to burn and split the sleeve. just guessing here though. anyway, next time run a wet kit. you wont even need a bigger pump for a 75.00 shot on an Si. And yes the block will be resleeved and find a new home in someones car that wants 30psi of boost or a 200 shot.

 

ouch sorry man

 

DRy shot is ok when you use a 50-55.....after that.........you need more fuel. SOrry to hear that. Nitorus is to expensive might as well go turbo.

 

Dude that was NASTY... What the **** did you do to that engine?!?!?!!?

 

OUCH, it makes me cringe just to look at that.

Good luck man.

 

word. My bro has had a zex kit on his lude. He runs a 65 shot and hasnt had any problems. The kit has been on for about a year and a half. With nitrous, it is critical that you know what you are doing.

GL on your new setup.

 

I'm one of NAWWZz's victims too. However, it was my fault for not taking all the precautions for fuel, timing retard, etc. Anyway, I got lucky and picked up a B18A motor (no tranny) in a Newark junkyard for $300.00. It was still in the car so I got to see the mileage. I had fun with the n20, but I opted to go the extra step and just go turbo. Good luck bro

 

Sorry to be off topic, but Do you think a block guard would of helped? I was a nawz victom as well. But it was just a burnt valve. Sorry to hear about your luck. Everything will work out... The way i see it, now it gives you an excuse to rebuild.

 

Yikes! that sucks

NOS scares me to many horror stories that I have heard keep me away from it.

I have even seen one moron basically melt his piston and rod down into the crank case with it.

NOS=To Scary For Me

 

I mod the preludeonline nitrous forum and we have yet to have a person blow a motor from nitrous when they follow the rules. I go to a dyno w/ a WB O2 everytime I change something on my kit that can affect the A/F.

 

All the people that I personally know who have blown their motors on nitrous, could have easily avoided it, by using their brain a little.

Anything from forgetting to install the nitrous jet, to running a 75+ dry shot on a b16 with sohc injectors .

Be smart, and you will love nitrous.

 

That is the most F'd motor that I have ever seen...

 

most definately.. especially on stock sleeves. I don't have the opportunity to have iron sleeves installed into my engine like you guys do (it'd cost me twice as much as it would for you, since i'd have to send my block to the states) so I use blockguards. Used one in my D16Y8, pushed 1.6 bar of boost through it, didn't have a problem at all. Used one in my B18C, pushed 1.5 bar by accident, not a problem. Used it in my B20B. Boosted 0.9 bar with stock pistons/rods - basically, stock bottom-end b20b, and it was fine.. and it still would've been fine if i didn't race that supra in 5th gear

anyway. my point is, blockguards do wonders. as long as they're installed correctly, you won't have any overheating problems like others have had.

B20B with stock sleeves.

 

dont forget those who install the n20 jet on the fuel side and fuel on the n20 side. not as bad as forgetting to jet it at all though.

 

wanan sell your blown up motor (i want the head for my b20!!) hehe

 

I thought the OBD I and II D & B series both shared the same 240cc injectors...

So you sprayed moroso with your coolant At least you got a new motor already, our SI has been down since November.

Most guys bust their motors by hitting the nitrous at too low of an rpm. Window switches are worth their weight in gold on any nitrous setup.

i think u might have had the injection for the nitrous too cloose to the intake manifold. it looks like u got a very uneven shot of it. i ran a 75shot on my b16a2 for 3 months, couple times spraying a week..no problems.

good luck with the rebuild!

Got Owned

 

**Raises hand**
I wish I had people to teach me about nitrous.
At least all that switching the jets causes is one hell of a rich condition.

 

hey laughin, its Mike, one of brians friends from UW-EC, u guys should make a trip back here before school gets out so we can all goto rock falls!
