right im getting myself so confused etc with what turbo i want i need some good advice or a good slap so please help first of all i have a wepr power up kit 1.5" runners , if i was to buy a td04 adapter plate and keep my mani , would the smaller runners improve lag ? also when does full boost appear on a standard engine with a td04 ? ____ RPM? also when does full boost appear on a standard engine with a ct12 ? ____ RPM? basically this is the argument in my head ct12 (the one i want) 230bhp ish but its = £570 TD04 230bhp ish but its = £70ish so my two options are keep my manifold kit , buy a new downpipe for td04, buy td04 line kit from TM-D , buy a td04 , shorten fmic pipe route, ecu and map sell my manifold kit, buy a whole new manifold kit , down pipe, td04, ecu and map etc please help td04 is so common but i know ill be the first in norwich with a td04 , but i dont want a laggy set up
