my 2003 lightning was heavy modded well guess what with 4000 miles on stock block rods went thru block.But JDM is building me a long block. temp was about 50% degrees this morning got on it getting on ramp stepped down on it and boom hole in block my 2003 lightning just had a total miles of 4000. so i played with fire and got burnt learned my lesson.I think jim told me they use the crower cams But i know JDM will build me a strong engine these stock block and rods sucks other lightning owners beware if you are modded and on stock block????? just got off of the phone with jim jr said they would build me a strong engine so from now on i will be running JDM motor.

 

Man, seems like almost every other day this time of year, I read about a blown engine.

Note to self: Stay out of boost.

 

Oh, what were your mods?

 

6# LOWER 2.80 UPPER DIABLO CHIP MODIFIED AIR K&N FILTER FTVB HEAVY DUTY HEAT EXCHANGER PORTED PLENUM SINGLE BLADE THROTTLE BODY BASSANI EXHAUST METCO IDLER PULLEYS PORTED PLENUM SPACER ETC.

 

That suck, but 50 degrees isn't that cold. Sounds to me a problem with your Diablo chip

But I will tell you the JDM engines are very strong and reliable. I bet I have the most miles on one of there motors and it is running real strong.

 

What's your timing?

Rich

 

Yes, inquiring want to know. BTW what was the A/F ratio?

 

air and fuel ratio was right on the money timing was 17 degress remember a stock block and rods in a lightning when it goes as mine did no detonation or warning what so ever if you are running with mods on a stock block BEWARE it gould go boooooooooom

 

Sorry to hear that,mine went with about the same milage but due to too much nitrous. Now i got a built motor with all the goodies.Im not sure i would choose J.D.M. only because of their high price,not being a hater or anything i just cant see paying more for the same thing when it can be had less.My .02

 

How many seconds @ WOT before it let go?
RPM?
Sounds like it was instantaneous.

 

Mine let loose doin about 100mph! I was racin a SS Camaro. Had fire comin outta both sides of the truck! Put on a good light show for the Camaro seein he was chasin me! That is till I exploded!

 

maybe so Don but I bet I got the most WOT miles on mine!! Stan

 

6# lower + 2.80 upper = what, 17+psi? How much power? 430-440rw?

 

I also did not see any exhaust I have seen more than half of the blown motors with boost mods but no exhaust.Might be backin up and can not get out fast enough and with what is still in the cyl and what is trying to get in might be to much and boom! sTAn

 

6# lower + 2.80 upper and 50 deg???..............Just a matter of time Not bashing anyone, but doesnt it seem like most of the blown motors have the Diablo programs? That coupled with the colder temps. this time of year sure kills alot of 'em!
