    Hi
    There are rules in the Road trans port act about how much hp overstock, hp vs weight and sub headings for forced induction.
    I suspect they don't care how many turbos it just has to comply with rulings .

    Hi
    Grew up in sth OZ . U had to fill out that many pages make your head spin . Try doing v6 into Torana in 87. Near impossible it was . Hood scoops even low profile ones were nearly all illegal . But funny that even some cars now have a smoothed in scoop .

    A mate could not fit quad webers 308 to much HP increase . ya kid`n !! Car completely 100% fully re-engineered build They were fitted after rego .

    What car is it??, they also run off kerb weight to determine engine capacity, naturally aspirated and forced induction have different formula to calculate

    It would have to weigh close to 2 ton, like 1900+ to be able to get a turbo charged 350 chev approved...

    Best bet speak to some engineers, as you need it mod plated anyway..

    hi
    What about a big block with alloy heads No problems to use max optional engine size then stroke it . This requires no mod plate .

    do you think that they would come very near that weight anyway? I recon those tanks would especially in big block configuration.
