Model Code is EV6 (vp / vn s2, vr aswell)
Ev6 has a diffrent balance shaft, slightly diffrent rocker design (guide plate is diffrent) diffrent inlet manifold (front thermostat) makes 127kw and 322nm ?, the camshaft is less aggressive than the ln4, individual coil packs diffrent fuel rails/injectors (alloy shinny fuel rails) it also had a bellmouth to smooth airflow, overall its a smoother motor than the LN4, revises also were rear main seal and a thick cast inspection plate which is a complete BITCH to remove in car, also uses a 8 bolt flex plate insted of the ln4 6 bolt flex plate. also had a fancy cover over the crank angle sensor and a diffrent balancer to the ln4..

Vn s1 is LN4
Both motors were originated from a Rover v8 that had 2 cyc's cut off, its 3800cc (forget cid) but both motors came out of a FWD buick in the states, also it has a relative which was the buick grand national turbo which was a twin turbo v6. and both have GAY ANNOYING ENGINE MOUNTS...
