Low compression in 2 of the cylinders = bad compression engine.
The only way to fix this is to do a rebuild ie. Replace piston rings is one option. But then that costs $$$ unless you can DIY.
Upgrading cams will not fix this problem.

how was the compression checked? did you do a leak down test?
if it's the piston ring/oil control rings you should be burning mad amounts of oil. are you?
get a second opinion from another reputable shop and if the results are the same then you'll need to rebuild..

If the two cylinders are adjacent, then it could be a head gasket or a cracked block/head. If they are not adjacent, then those two cylinders are just plain shot....need to pull the head to determine the cause. Either way, it's time for a rebuild of either the head or the cylinders.

snif snif .....i thing i will go for type r pistons ....is it a good move ?
can compretion help performances with no cams ? ......is anything else from the intervals that i must replace once i open it ? the cost is high but i will know that the engine goes like new right ?
if i go for other b16a2 its a blind bye i can not see inside....so my only option is rebuild ...................they ask me near 1200 $

You don't need new pistons.... at least not for sure. You have to open the motor to decide what's a reasonable way to go. Gotta know where you're losing compression, since it could just be a gasket, or it could be a cracked block. Could be worn valve seats...
