the other day on the way to the dyno i fucked my car up. today i pulled the head off and discovered this. i think it may be due to detonation because i was runnin a 10:1 compression. i say this because the car started sputterin real bad before it blew

 

you did a good job on that sleeve

 

Ouch..

Working on answering your PM..

 

How much HP were you running? I thought the sleeves were good for 400 Hp at least.

 

not on a 2.0 and DEFF not for that 2.2

 

not an lsj

 

gm rates 2.2 sleeves at 400hp

 

yeano

 

um yes

 

Yeah I know its a 2.2 thats why I said I thought they were good for 400hp. I didnt know there was much of a difference between LSJ and L61. Ecotec blocks should all be similar except for Gen1 and Gen2. Thats what I was lead to believe anyway.

 

damn that sucks time to hit up darton maan lol

 

you were lead to believe right....gen 1 lsj and gen 1 l61= same sleeves

 

i know im half drunk but gen 1 l61 and gen 1 l61 looks like the same thing to me too

 

fixed haha

 

one word.....damnn

 

thank you lol

thats was my reaction too when i saw it, but to be honest im not even mad about it, it was bound to happen

lol thats ironic. i was on my way to the dyno when it happened lol

i got the gm build chart ratin my sleeves for 400hp, i tried testing the theory but didnt quite work out lol

cheaaaaa

thats a maybe. i might put it to stock, i already got a for sale thread going to test waters

damn right, cracked that bitch in 2 places

 

buzz kill

 

looks like you lost a ring under boost and that's what really cracked the piston.

 

How much boost?

 

lol, i saw that too. i was like "wtf? how did that get there?!"

it was at 15 psi when it blew, usually on about 20 because it dropped down for some reason

 

you saying you had it up to 20psi?

 

yessir

 

not cool. but you already found that out. woulda been nice to see the numbers before she popped.

 

yea....sucks it blew on the way to the dyno...i have the worst luck i could either spend $1300 on parts to fix it plus labor orrrr get a new car...im on the rocks

well labor of puttin sleeves in, i can take the engine out myself. im half way there already...ohh and plus i need a new transmission cause my 3rd gear is going out

 

you gotta admit u love the sleeper status haha u dont get that with an srt4
