wow..RM5800, actually still ok la hahaha ..but RM580 i also don hv :cry_smile: hahaha cos i hv cin cai calculate to mod that as i aspect... JUN 272 degree high cam, titanium valve n valve spring, port polish, crankshaft balancing, Mugen metal head gasket, the block guard, top fuel 2.3 kit, MSD, HKS F con Vpro or Apexi power FC..already cost over 10k...pengsan hahaha..
Turbo is more hard to mainten la ...actually upgrade turbo engine also very expensive...cin cai cin cai also can cost u over 10K...this more crazy...
