    Hey all. First time poster. Currently I own a VF11 SV6 in manual and toying with maybe trading to a VXR (even though I dislike auto's with a passion). I know there are few options for getting more power out of the VF V6 but wondering if anybody has done anything with the new V6 motor in the ZB as I believe it's a different engine. I'm no expert on any of this so please be gentle if I've got my info wrong.

    Cheers.

    Keep the VF
    At least you'll be driving a real Commodore

    Sell the VF and buy a VF Redline.

    Yep, that's a better idea
    A real Commodore with a V8 ;)

    The LFX on paper has more kW than the old V8s, but peak torque is is pretty high. Maybe if you go to some GM American forums, there might be people who have tweaked it. One problem might be the 9-speed transverse tranny can't handle extra torque.

    I have seen a post on FB of a ZB V6 that was fitted with a Unichip piggyback ECU. The gains were 60Nm and 30Kw at the wheels. Not sure weather it was some creative Dyno work but that is a decent gain. The cost was $1600. From the pic that was posted it's not plug and play unfortunately and required the new ECU to be spliced into the factory ECU wiring.

    440 nm sounds quite tastey.

    Yeah, the 5 litre lump of iron, and also the early editions of LS1.
    Sorry I said LFX in that post, I meant LGX. 235 kW in the ZB. In the Cadillac CT6, it pumps out 250 kW, but that is with longitudinal gearbox that can handle the extra power.

    The CT6. Now there is the GM car they could have gotten away with rebadging as a Commodore.
    SUV option, V8 options and pokie V6 option.
    Holden would have been saved.

    Thanks to GM management short sightedness, another Alpha platform vehicle NOT produced in RHD...

    The old VK and VL power was somewhere about 120Kw, VK Torque 336Nm at just 2400 - VL torque 323Nm @ 3200 - remember the ad with the VL Commodore passing someone on the Nullabor, as the VL goes past it's towing a Yacht.

    3.6l LGX Commodore ZB +32awkw + 60NM
    2.0L Turbo +45awkw + 75NM
    We're acheiving this with a dyno tune only for $750!

    On the 2.0L with our Methanol injection plug+play kit we're getting 70awkw + 120NM. Similar to the Audi S3's!! $2200 drive in/out.

    TRANSMISSION tuning is a MUST on these, it will make the power on the dyno but on the street the trans limits torque! So if you're planning on tuning either of these cars make sure they do the trans as well!!

    Curious about what would need to be done to the LGX V6 to get an extra 32 KW and 60 NM which should it seems bring it up to 265 KW and 440 NM?

    Stage 2 suggests other bolt ons, but doesn't specify what they are...

    And has anyone done one of these upgrades and run it down the strip - with a 9 speed auto it should hopefully be in the same ballpark as a VE SS?
