Hi !   As in the topic : Turbo conversion of (gasoline) Citroën BX  would be a natural thought when considering the obvious potential of the cars low weight .  :)    First, one might think of the "16V" 1.9 litre - already w some healthy speed (148bhp) , but actually both the 1.6 litre 8valve and even the small 1.4 litre engines seem interesting to my mind -  the deciding factor obviously being the low weight of the car.   Even a modest 100bhp per litre in the 1.6 engine appears  tempting..  :ph34r:  ( better torque band than in a relatively highly tuned normal aspirated engine ).   Anyone with tips ? Comments ?   Except from older versions of the BX, all engines are fuel injeccted, from what I gather.  That definitely helps a turbo conversion. And... Keeping boost pressure low - say 0,5 bar - would make low  compression superfluous to an extent.     Thanks for your answer !   Cheers !   'G'
