    Red face About LER and LEH differences

    Hi guys!

    I was wondering what's the difference between LER and LEH engine, besides 200hp vs 240!!

    I have a 200hp astra and as i understand it can jump to 240ho with a rempapped ECU, but what if i switch to the LEH turbo and remap???

    Thanks in advance everybody!!!

    I think you have a spray bar under the pistons which cools em down but I may be wrong on this

    ZLET and ZLER are the same apart form the software map.

    ZLEH has teflon skirted pistons, bigger injectors, updated turbo, oil spray and a single balancer shaft (ZLET/LER has a twin balance shaft). LEH also has the M32 gearbox.

    Each piston has an oil spray jet attached to a bar which is there to cool the underside of the pistons.
