I use to run buggy and have run difference engine - JP SBK, JP Pro99, Collari Mod Nova, Picco G1 pro, OS 01B and VZB. Among all the engine the VZB is my favourite.
However after I try the V-spec on my new buggy and all I can say is the V-spec run so much better than the VZB. At 100 degC my engine is on par with those guys running the 421 and S7II. The mileage is also very good, on average I am getting about 8-9 mins.
