hi NISMO,
you are probably right to this point, as i caculated last night, AUS$5900 is for the twin turbo kit, the rest like exhaust, fuel system, ECU and FMIC won't cost another AUS$8000, beside if i am lucky to get the 2nd one, the costs are reduced again...
but, anyone has ideas what is the A/R for APS TT turbos? becuz for HKS GTRS turbos, they are rated as 0.64 of A/R and they can produce 273rwkw with standard internals? (i am not too sure if i am correct)
cheers
