They're good people, my cuz and another friend both got swaps from them, and they came out perfect, steve i believe was the guy takin care of it. Plus if u look at the topendmotorsports website, they call it a B18C1, but they claim its from a japanese gsr, a japanese gsr would be a B18C, USDM is B18C1 soo, just sumthin i noticed. id def go with hmotorsonline, they'll get u the jdm gsr (10.6 compression) and u wont get stuck with the USDM (10.1)
