i just order ahead of time

well idk what the stock sleeves will hold but everything else seems like you could make 400 on a 57mm

 

lol me too but i run the 7EIX irridiums much better results

 

josh. this is what i've gone through since coming home from CED. minus the box on the bottom and three on top.

6 sets. plus whats in the car now lol

 

i have the gen II block its suposed to be rated to 500hp.. guess ill find out...lol

 

I will order an extra set tomorrow, so I always have 1 extra on hand. So ordering two sets at a time will allow me a spare set for my glove compartment.

 

Damn that sucks. All the Napas in my area have them in stock.

Do you have a wideband?

 

Yes, but just the gauge, not logging it at the moment.

 

I have a pile of used spark plugs laying around like that. i just go ahead and change mine every oil change which is about every 2 months. I went to a parts store here and just bought a case a few months ago.

 

Whats the AFR at WOT?

 

It dips down to 12 but doesnt seem to stay there, When I would get it up to 20 psi on the highway it didnt feel right nor dip below 12 so I didnt hold it. Probably the only reason I didnt pop something. Also I know it was lean because fuel ran out in 3 and 4 cylinders, the other two plugs were still decent.

 

12 what? Does it ever go to 11's WOT?

 

well I threw some stock plugs back in my car to trouble shoot some things. I have new sparkplugs arriving tomorrow.

Funny thing, the engine has a shimmy to it at 1500-1750 rpm but smoothes out at 2000-7000, no smoke of any kind out the exhaust. What would cause the engine to be off balance at low rpms? There is no knocking or vavle train sounds out of the norm. the engine kind of runs like its cammed.

 

Right now, after reading a bunch of stuff online and getting a misfire code, I think the shimmy is due to a cylinder not firing. Could just be my crappy stock plugs in the car but I will know more tomorrow.

 

that picture is just one and a half month's worth though

 

Ima guess busted ringland esp the way those plugs looked good luck tho

 

Exactly how my car sounded cammed and wrx sound = pull out the wallet

 

hope its not your motor... I found pieces of piston rings in my intake manifold a week ago.... need to get the motor out and look

 

are we talking about c130aviator?

 

in your intake manifold? how the hell does that happen

 

Yes, well fellas the verdict is in and I am now a casualty of bad tuning and being stupid and running out of fuel over 20 psi...

Compression

#1 - BIG FAT ZERO
#2 - 100 PSI
#3 - 130 PSI
#4 - 130 PSI

I turned the engine over until the needle stopped on all of them...

No burning smoke out the tailpipe. Is this stricktly a head problem? Burnt valves?

 

damm man not looking good. and you were tunning the car your self?

 

No I had some help from two 20G owners and it is NOT their fault. I wasnt watching my boost gauge and after I installed a MBC it was well over 20 psi. I ran out of fuel in cylinders 3 and 4 and bam....

I think its the valve train.

If it were the pistons, rings, head gasket the car would be smoking like the Marlboro man.

 

I am really not too upset. Thinking its time to upgrade this 77000 mile engine...

 

what do you all think, based on the info I have found thus far? You think my rings are ok?

 

Doubtful, pull the head and check. Most LSJ bottom ends are the first thing to go, so i'd bet on that first.

Plan on pistons at minimum, hope there isn't much more damage than that. And be ready to tune properly when you put it back together, or leave it on lower boost.
