i have a b16/b20b and je 12:1 pistons. I know the b20 sleeves a supposed to be weak, but will they hold? I plan to turbo it next year but i want speed now.

sorry for the question im sure you all have talked about this before.

 

The b20 will be fine at that comp.. But to add boost is not wise with the stock block and the comp. being that high your asking for i to blow up then.

 

what about 15:1 compression? what about posting? sleeving a B20 doesn't seem like a good idea
