Yep, looks healthy. Mine came up 155 on all 4 after a rebuild, but dont be concerned about a particular number, as many different compression testers are not calibrated the same, just be concerned that they are all within 10 psi of each other.
How is the motor going now with the RB20 turbo? Do you run an intercooler?

no intercooler very much in a test setup, no exhuast, cant get past 5psi for some reason but that 5psi is easily availible at 3000rpm in 1st and 2nd, go around a corner with ANY boost at all and it will spin the tyres.
i'd imagine the reason i cant get past 5psi is a leak somewhere in the intake piping, its not particaully secure because of the odd flange on the rb20det turbo, its going to the exhuast shop tomorrow to have a rx7 series 4 intercooler front mounted and custom dump pipe matched up to the current 3" exhuast.
it doesnt feel any faster than the ct20 or the t25 i had on it, but i havent had it over about 3000rpm as it doesnt have a wastegate or exhuast - and if its leaking then it will have a large effect, its also running stupidly rich, i put 8 brand new plugs in it, and during testing (1hr of running MAX) the plugs are black and sooty. so theres a few things to sort out, the turbo doesnt currently have the water cooling piping in yet either so im a bit scared to run it for long.
