ahah ok ok if u r goin haltech way 1 then no worries. Buy haltech E6X. Turbo ah, my fren kelisa is using IHI RHB 5 lah, if high boost then use front mount IC. Heavy duty clutch, lower compression using gasket n grind some part of the top of the piston. n also i think need bigger fuel pump n fuel regulator. Brake system also need to upgrade coz original cannot stop . Got 1 kelisa i know using E6X running 1.5 to 2 bar go ard 150 hp at wheel.
