so this is the engine you'd recommend

30009 - B18C 94-97 (GSR) Complete Change Over
180Hp 126Trq 10.6 Compression (JDM)
170Hp 121Trq 10.1 Compression (USDM)

what are the major advantages of doing this swap over the B16a? Labor wise are they about the same or would one be easier than the other, and is the performance of the B18c worth the extra money?
thanks for the input so FAr...
