ive been using this engine for few years now.. last time when my bro transplant the engine, it was 2k++ including assembly for an auto ones.. my comment is that it is a good and reliable engine.. forget the clicking sound during morning start and ull be more than happy using it.. :P power for the engine is good, even though not as big as 4g93 but sufficient enough.. fuel consumption is ok.. 450 - 550 for 50 bucks of petrol, depending on ur setting..
ohh, my piping setup is 2" front to back and 4-2-1 extractor.. lastime using it with standard muffler, mid to high range power is realy good.. now changed my muffler already to S-flow ones.. power not so good la.. but its leaner and the exhaust note is realy a music to my ear.. :D
