i was wondering how much WHP can a stock ls b18b1 sleeve can reach befor it cracks or worse explodes???
heres my set up :
b18b1 block
srp pistons 8:5.1 cr.
egale h beem rods
acl race barings
and a Garrett T4 turbo

 

There are a number of different factors to consider when trying to determine this, but I wouldn't try to go for more than maybe 300 before sleeving. A lot people sleeve the block only pushing 250. Better safe than sorry, so it wouldn't hurt.

 

thoughs numbers are to low plus i whant to get the full potential of my t4 .. i guess im saving up for sleeves now ... are AEBS sleeves any good ?? and how much are they just fir the sleeves alone ??

 

The stock sleeves can handle a bit more than the numbers I quoted you, but like I said, there are a lot of factors to consider: what if you over-rev the engine to 9000 rpm's; what if it's not tuned properly; etc. AEBS sleeves are good, but I'd do a search and find info on Benson sleeves, I like the open deck design a lot better, and no you will not have "cylinder walk" issues.

 

so then whats the big diffrence in closed deck and open deck , if its sopose to prevent crank walk ??
