can I trust b20 sleeves if I fill the block??
 

I got these CP 84mm forged pistons and im getting eagle rods this week. I have a b20 right now and I was wondering if its worth it to fill it. or should i just sleeve a LS block? because i dont want the sleeve to crack and ruin these brand new pistons

Re: can I trust b20 sleeves if I fill the block??
 

The b20 sleeve in general just sucks. Very few people have been lucky enough not to crack them. The filler isnt gonna really help the fact of the major flaw the sleeve itself.

well seeing that you already have 84mm pistons it really wouldnt matter which one u decided to do, they will both be a 2.0L in the end.

Re: can I trust b20 sleeves if I fill the block??
 

they will both yield 2.0L my friend but how much HP he can push on each block will be determined by the sleeves themselves. B20 I say about 300-350whp. Filling wont do shiet because it cracks between cylinders unlike the other b-series block. On the other hand, B18 with sleeves... Your HP will be determined by the size of your balls and tuning ability.

Get the picture?

no way, 250ish you better be counting your blessings

so basicly i should leave stock internals in the b20 because forged would be pointless without sleeving? thats what im thinking so maybe run 7psi max on it with b16 head

pretty much. Thats why b20's are so cheap these days. The truth is out. Good block for simple set up. High Comp or High Boost bad idea

If you fill the block, as long as you dont drill to much filler out around where the cylinders meet, you should be just fine. The only reason the sleaves break is because they are together and they walk slightly.. but the filler will stop that. I'm doing the filler right now. just waiting on it in the mail.
