GSR or B18?

Originally posted by AzCivic
they are both B18's, the GSR is a B18c and the LS motor is the B18b. They both take about the same time and money to put in. The B18c1(GSR) has 170hp stock while the b18b has 140stock. It all depends on how much you want to spend and what you want in the end. the gsr motor costs more(the engine its self) but has more power while the LS motor is cheaper and lets you have money left over for other mods. Do a LONG search on google and you'll find any and all info there is on these swaps.

when you say B18, please specify which one you're talking about. Pretty much, this guy is correct...but IMO, I would get a second gen B16A which is the same HP as a B18C1 (USDM GSR motor) with a little less tq, but costs on the regular about $800 less than the B18C1. With that extra cash, you can do all sorts of things to your motor It all depends on what you want in the end though...do you want to stay NA or do you want to go FI?
