what type of fuel management are people using when they have the famous sleeve failure. also is detenation the only thing to possibly cause that. I'm thinking of running my greddy kit on my current setup B20B with gsr head all stock. i figure 5-7 psi should be ok as long as it does not detenate. I' read the many b20 posts about people cracking sleeves and what not but there are those that manage to run this with no problems.

 

I have a buddy that cracked his sleeves on 11 PSI. He was using forged pistons and rods and running a Hondata S200B. The simple fact is that these block shouldn't be boosted over 8 PSI without sleeves. It's kind of an "all or nothing" thing. You should be OK as long as you stay below 8 PSI.

 

thanks for the info. i figure its a gamble.... any one else with input ???

 

talk to TurboPanda...
he had a b20 boosted ~18psi with a block guard and stock sleeves...it can be done.

 

Yeah B20turboic boosts his B20 to 15psi daily with Zdyne.... stock block...

psi doesnt mean anything its the size of the turbo. a t25 wont make the same power as a t4 at the same psi. so depending how much power you make should be looked at first.

 

I believe hes running a t3/t4 that flows quite a few more CFMs then a t-25....
