I bought this Vacuum and Volt meters from Speedster_jg recently I must say it is well worth it. It was expensive to actually get it installed at Kelana Jaya "ABANG" , RM35 to be exact to DIY is preferred.
i got a quotation of changing my td04 twin fin to td05 16g big twin fin using back the original housing...quoted around RM 1.1k plus totally overhaul the turbo....
