H22a replacing pistons question
 

I cracked the ring lands on my stock h22 with boost. i bought JE 9:1 pistons... im told AFTER i bought them that i HAVE to sleve it or else it wont last but 1000 miles. why is this? or are they wrong?

Re:H22a replacing pistons question
 

Your stock sleeves are homo and made out of Smagma which won't bond to the piston correctly. You heard right. :-\

damn..... so IF i can return the pistons i bought what kind should i get because i dont have the kind of cash it takes to sleve the block.

I'm no H series expert so my advice isn't worth ----, but I would suggest the factory OEM parts if you're not going to sleeve it. :-\

Factory cast pistons for you my friend...

Re:H22a replacing pistons question
 

Ok is there a such thing as 9:1 Factory pistons?

Re:H22a replacing pistons question
 

So if i want to keep boost.. what can i do? OEM pistons? and lower the boost so it doesnt blow the ring lands again? someone help i need some advice..

Re:H22a replacing pistons question
 

ya use your stock stock pistons and run a thicker head gasket to lower the comp. getto style lol

Re:H22a replacing pistons question
 

how much boost were you pushing?

Re:H22a replacing pistons question
 

9 psi

Re:H22a replacing pistons question
 

try not to detonate...get a EGT and check the exhaust temp's

Re:H22a replacing pistons question
 

kinda off topic but did you ever dyno your car at 9psi if so what kinda hp/tq where you making

Re:H22a replacing pistons question
 

what year h22? open deck? closed deck?? power numbers??

if you want to keep the boost, don't bother pulling the motor apart just to replace it with OEM. ---- THAT!!! wait and save your money. get it re-sleeved, and build that bottom end right. do that and you can make some serious reliable power. if you put oem stuff back in and keep boosting your just going to run into the same problem you have right now. and building it w/o sleeving it is just like puting oem stuff back in. re-sleeve that thing man!!!

Re:H22a replacing pistons question
 

I already had theo motor tore apart when i got the pistons... ANYWAY.... i decided to sleve it with darton sleves and get soem good rods and use the JE pistons i got... i got to wait 2 months to have the cash.. but i guess its worth it.

Re:H22a replacing pistons question
 

oh its worth it alright! It's going to feel like a long wai though ::), trust me... Good luck, oh and what kind of numbers were you putting down on 9psi?

Re:H22a replacing pistons question
 

i never raced it with 9psi because i didnt have it fully running good and tuned. my best time was 14.3 with a 50 shot.
