Another,... BLOWN motor!
Freddie, points for proper use of Lou Ferigno 
I put it this way on torque-
400 ft lbs- 49k miles (revving to 8300-8500) at both 434whp stock turbo and 574 big turbo, My car.
425 ft lbs- 2 years, 13k+ miles/pump meth, CA$H tune was very aggressive and led to bad HG.
445 ft lbs- unknown miles or time, still*boostin
470+- 3 days, aggressive torque spike and it looks like there was a CRAPLOAD of timing on that map. LIQUID
There are alot of other torque levels to fail ratio but these are the "averages" so you can see how it starts to get exponential pretty quick.

Could be few reasons, meth kit / tune / too much boost for stock internals?, sorry to hear that. thats 60k on the motor allready, maybe you over-rev it? above 8k?
I got mine up to 100k on stock block, when #4 cyl decided to meet with sparkplug...

def not over revving. rev limiter ist at like 76-7700rpm i think. i shift at 7500ish. who knows.
that motor was ragged out and has served it purpose. time for a 2.4L to take its place. only thing i can think of is it would of had to just been to much Trq.
i do like meth. but ive had enough fun with it for awhile. the car was tuned for around 26ish psi. but sometimes with the turbosmart MBC it would spike to around 30-32ish, with no knock so id just let it ride.
always wanted a built motor. so now i got it! thinking going with an fp black set up. but GT42's are pretty sweet too,... LoL.
or maybe a gt40 on 40ish psi on race?

Im the one that tuned this car and trust me it hit more than 23 psi in fist gear. On the 2 step it would hold 20psi. The day it blew up he re did some of the meth kit and added a fail safe that day. He broke the nipple on the labonte meth box and he did something to it idk how he got the line to stay but from what he said the meth started to act weird when he did the changes that day. Like just randomly spraying meth or something like that. I know it wasnt the tune. the car had no knock and u can clearly see on the plugs and pistons. I rarely go in the forums and post so most dont know me. Im the so called Vega tuned. I have tuned alot of cars in here and other none evo cars. Some of the bigger known guys in the evo world might try to question my work bec they dont know me or seen my work but theres plenty of people in this forum that can vouch for my work. I tuned joes 520whp plus 100k miles 4g63 fp red and meth that he ran that set up for a year with no problems. Its sad to hear about Wills car bec that thing moved with barely any mods.

Sounds like there are alot of "sounds like" things we've all noticed and alot of "could have been" but without him monitoring his stuff there is no telling. Also sounds like he has a new motor already and doesn't care too much

yeah i deploy next week. so when i get back ill get to toss her in with and FP Black and call it a day.i would go bigger but i got a 91 awd talon to work on too..
With time my dyno tuning and working for Hondata, one of the first things i learned was that high revs(higher than what the harware was designed for) will kill an engine, just as fast as bad tuning.
I can't say for sure what the stock bottom end limits are for high revs, i have not done all the math, but i'm assuming it's no higher than about 8500-8600rpms. The Stock 4g63 rod ratio is not optimal for high revs.
Remember that the force on the rod is directly proportional to piston acceleration. Rods tend to break under tension. The magnitude of piston acceleration is at it's highest at TDC.
Moving on, how do you feel about the FP Beehive springs with the stock retainers? I see you talking about them a lot. I'm actually thinking about grabbing a pair when i order my FP Red next week.
Ahh, it's great to be back on EvoM.
ive seen this before on a stock motor w/ just an fp green on pumpgas w/ only 25psi... the motor had 70-80kmiles on it and was beatin all the time. My take? the rods just let go. Nothing you could have done to prevent it. It DOES happen randomly to 4g63s w/ alot of mileage or simply high rpm abuse. Also anything above 400ftlbs of tq on the stock rod bolts/rods. Contrary to what many think... its NOT the head bolts that are the weakest link on this motor. Its the rod BOLTs. They simply suck (for a lack of better words)... they stretch easily and WILL let go from tq exceeding 400ftlbs or high rpm. Some motors last most done... basically its a gamble w/ those two variables being at that point.
If I was you I would make that block a coffe table(I am not making fun of you). As per the engine failure, well, I am also staying away from methanol for a while, I ran it back in 05 and 06 and I did a lot of testing but when things fail you are screwed.
Time for E-85.

Looked like the rod bolts were still there. I would point at detonation to fold a rod like that.
If the meth kit/ spray pattern was any different from the original tune, Its not "tuned" any more...

Agree however that yes it could be one of many scenarios we are pointing out. Bottomline it sucks, but hey just rebuild... it'll be that much better
