    Thorney Stage 5

    Any one know much about this? I dont think it has been released long, i can't work out from there website if its a VXR Stage 4 or a Z20LET Stage 5.

    Either way it looks good for £4500 Fitted doesnt look bad to me.

    330BHP/390ft/lbs - Would a standard LET bottom end be able to cope with that?

    There's a guy running more than that on a std bottom end with a garret setup. I remember him saying it's down to how it's mapped and the A/F ratios

    yea there description is confusing i think they may have made a mistake with LEH as it states that the engine will need a fuul bottom end rebuild so regardless of being leh or let wouldnt matter either way

    sounds pricey, maybe get some of the bits done before to lower the cost
