change to fuel injection u must have the complete kit la... u will need an external fuel pump... convert to fuel injection dont need 3k laa... around 2k and below can settle... coz workmanship charges varies alot... injection kit nowadays cost approx 1k...
benefits??... not much i guess... dont expect fuel injection to be super fuel saving compare to carburetor... mayb slightly better only... |
