so i purchased a jdm h23 and dropped it in the car, before starting up, we did a compression test,

cyl 4 - 170
cyl 3 - 220
cyl 2 - 70
cyl 1 - 90

before installing the engine all i did was change the timing belt... the cams were at TDC and the crack procket key was at TDC also... what else could this problem be?

 

Plenty of things. Is this blue top H23 VTEC? Because, otherwise, it's not JDM
