4g93t compression test

[svanh1993]

after forging the motor and building it over time I finally got it all together seems healthy to me now
dry test wide open throttle
cylinder
1:176psi
2:182psi
3:174psi
4:182psi
over all the motor was very clean inside even before I dismantled it to rebuild it
forgot to lap the valves but that's okay as new cams and valves and springs etc will be the next mod lol have to save first so I'll enjoy my new motor with stock cams and all my old running gear as a gt3076 is next on the list

what has other people gotten with the 4g93t ?compression test seemed fairly high for low compression pistons but anyhows cheers guys

I dry comp tested my 93t recently and came up as 150ish across all 4

G'day. Seems a bit high?? Are the forged pistons for Turbo or na?
Cheers

turbo dish pistons 8.5 Cr maybe the mls gasket is giving it more compression
?
