give or take b20 with b16 head. compression should be around 9:1(someone correct me if i'm off) so your compression test should be around 180 give or take..

 

so it shode be 180psi for the test
cr 9.1 what if its a gsr head ? the compression is not even that high will it make a good turbo or nos set up?

what if the block is built with piston ? type r reps

 

stock b20z1 for me popped 210-220 psi a cylinder.

b20z1 with 11.8.1 ycp itr spec pistons popped near 250-260 psi a cylinder

both on a stock b16a head

that was on a snap-on compression tester, not some cheap as s$20 dollar made in china piece of crap. you get what you pay for in quality and durability when it comes to good tools.
