Default BLEW MY AXIS STAGE 2 lol

Well guyts it was fun for about 6k miles. But now I must be moving on and nputting a better engine in my car. THe engine took quite a bit of abuse before then rings went out. But i just cant help but think that the piston that the rings went out on was already bad. As soon as the engine went in the piston that went bad wouldnt fire from day 1 properly but did have good compression. in the initial tuning the was some harsh detonation But I had gotten it where there was no detronation. Well not a bad engine just couldve been better.

what do you mean the piston wouldn't fire?...sounds like an electrical or plug issue to me.

sounds like the detonation could of damaged the engine not a bad engine its not normally the engines fault it detonates ,its the tuning.
If there was enough oil in the cylinder to cause det and misfire from cold it would of smoked like a train .

yeah well nit did smoke like crazy on a cold startup. once warmed up all was well. I sure detonation had a lot to do wiht it too but the last 3k miles of the motors life was detonation free.

Sooo, when you say smoke like crazy can you show us a video? Whats the compression at? What are your leak down values?

I remember your tuning posts. How much boost were u running?

Heh, 3k of detonation on a built motor and you expect it to last?

IMO, you need to fix other problems before putting another built motor in there.

I'm going to say the motor was killed in the initial 3k miles due to detonation...poor rings never had a chance...
what did you do for your break in period?...please be complete and precise with the answer.

I dont remember putting a post blaming the engine for the detonation? I blamed it for not firing on the cylinder that died!

I'm still wondering why you are blaming a chamber for not firing...either it was your fuel or fire that was not working...that piston, even with rings in a straight line will make enough compression to fire...
I personally think it was your plug gap/temp range...either that or a short.

What do you mean a cylinder didn't fire? Were you able to verify the cylinder was not getting spark? I would assume that if you were getting good compression numbers, the rings seated fine.

Also, the detonation you experienced could have been caused by a number of variables, and a few I could suggest just based on the info in this thread include:

1.) Gas quality/octane
2.) Poor intercooling
3.) Tuning

These three variables lead to detonation which killed your motor. Live and learn. So what are your plans now? Rebuild?

Other people wonder as well. Your original post doesn't really have a point or a question to it.

Definitely gonna do a rebuild. This time with a hx40 holset and prolly better rods and pistons on a ej257. Hell its just a motor. mr complex moderator FYI my post is very informative due to the fact of sharing my experiences of the axis stage 2 motor with what mods and tuning i had. so piss off

it very well could been killed die to detonation. The problem was is that the inter cooler sucked major balls for the turbo i was running. just got too hot and liked to detonate. I dont have any smokey videos either. either way the ring wasnt set up right anyways. I am not knocking axis motors either! i think they are pretty fair quality. at least the stage 2 is. My motor detonated under light boost since i started tuning it. I dont know why either. I wanted to run 15psi on pump at about 17 degrees timing and it would detonate. i had to back it down to 14 degrees before the detonation went away. I am pretty sure the egts were just too hot and the intercooler had A LOT to do with the destruction of the engine. I am not mad about either you dont hear me blasting on anything just sharing my experience.

were you sure of your gas quality? And did you check your entire setup to ensure that there were no othe probles that were causing you strife in the tuning department?

I beg to differ. Your post not only had no question or technical information in it, but your spelling, grammar, punctuation, and thought seperation outright suck.

Perhaps someone will complain about me "getting in the last word and closing the post" but frankly, this post is going nowhere and has nothing to give to the community other then to make sure to get your car professionally tuned.
