    F23 Range Ratios

    Does anyone know if there are any F23 gearboxs on other vauxhalls that have the same ratios as a Astra GSi?

    Think the coupe t and 888 are the only ones, the 2.2, v6 and diesels are all differnt. The best box ive found for higher power z20`s is from the 1.7 cdti corsa c.

    definitely not the Zafira as it is slightly lower geared, a good box if you want one for max acceleration though

    Might sound stupid but i just assumed that if i used one from a 2.0 na for example on a motorway the revs would be sitting higher the box off my astra gsi. Thought this as the na needs to be reved more to get it to go where as the gsi has a turbo
