not the tuner..i know that

 

that sucks hardcore. what was AFR on wot? the sound coulda been detonation, but you would see it on the spark plugs and it sounds like loose change. otehrwise, i am with others, lubrication issue total bummer.

sleeve it and build it. stronger then before

 

Proven? Hardly...truth is there are really only a handfull of turbo guys here and an even smaller number of guys running high power with or without a HG. I know a couple of modded s2000 guys that have never even heard of s2ki before. In reality, we are only getting feedback from a tiny part of the population. Not to mention there are some large egos running around here that would make me question the validity of their relability claims anyway.

When you go FI, never for once think anything is proven. Adding something like FI can easily blow your motor as shown here.

 

Proven doesn't mean anybody can do it. Or that it's easy to do only that it is possible. If my 100% stock engine can hold up to 600whp at 26psi on a much bigger turbo than 10psi should be no problem. Something went wrong this failure was not because the engine was simply to weak. My guess is you will find detonation when you open this one up. What spark plugs were you running? How many miles? AFR? Valves in spec?

16* isnt exactly super conservative. I run some pretty serious race gas and MBT for me at 10psi is 17.6 granted the fuel I run probably burns a little faster than 93 but still.

If I'm not mistaken the "S2000 from hell" was on a stock motor to (maybe a ported head?) and he was making 700 on a turbo even bigger than mine although i don't know how much boost.

 

I know it can. Here's the deal, I think the motor had to be damaged before we got on the dyno. The fact that it lasted those 4 or 6 pulls at 10lbs was luck I guess.

Miller said the same thing, he has never seen a motor fail the way mine did. He was very safe and said he didn't want to blow anything up, so brand new 9 series plugs were installed and checked frequently.

And the noise was not detonation, it only happened when VTEC engaged no matter where it was set. It honestly sounded like a cracked valve spring sounds, a loud rattle. But like I said we pulled the valve cover and checked the lash on each rocker, and the plugs were pulled before and after each pull. No signs of detonation, although after the last pull miller said the plugs looked like they had aluminum on them. I was using 93 octane gas from the mobil by my house which I get gas at everyday, including today I filled up my turbo civic and beat on it with no problems.


I honestly don't know what to do. I have no money, so there is no way for me to build a motor right now. Only way that will happen is if I let the car sit and save for a couple months, which would really suck. But I also don't want the car to blow another stock motor if I go through the trouble of pulling this one and putting in a new one. ahhhh!

 

Sometimes stock motors just let go. Just because it shouldn't happen doesnt mean it wont. Doesnt need to detonate or run lean. Doesnt have to be a bad tune. It sucks but it does happen. Ring lands do break on these motors. Shit happens.
Sorry for your loss. My recommendation would be to find a stock long block if you are tight on money. The motor *should* live a long happy life at 10 psi.

 

Iridiums? do you have pics of the plugs. I've seen a good handful of motors blown because of failed iridium plugs. How about pics of the cylinder and head in question?

If the plugs looked they had aluminum on them that's pretty much the definition of signs of detonation.

 

Im sorry I dont agree with you. The stock motor is proven as in every other day someone is making 400-500whp on a stock internal engine with a 3mm HG or stock HG. I dont see how one guy like Jeff can make 701whp and then this car blows up @ 10psi. We know the internals can take the abuse, we know the tuner is good....so it was something out of the ordinary. I run 10psi every day and beat on my car....engine seems ok to me. So Im gonna go with this is the exception and not the rule. I know you like to disagree with me, but I have a valid point.

 

dude im so sorry to hear about this. If I was you i would do another stock engine. I beat on mine a lot and she runs like a top....I think you had some bad luck. Something internally wasnt right it sounds like. Again though, I still believe the stock interal engine can handle what you want.

 

Be specific please... It was ONLY the Denso Iridiums (Which I tried and they DO suck)
The NGK Iridiums are very good though.
