Okay guys, I been tryin to figure out if the car Im buyin has a b20b or b20z...reason being is b.c. the guy told me its from Japan so JDM b20, he says its JDM b20b meaning low compression, but he also told me its the high compression one, so Im confused...and I really wanna know which one it is, I dont really care cus both of them are cool motors but I wanna know if I should turbo or all motor obviously...umm...someone told me that I can just go to honda and check vin number to figure out what car the motor was originally in...but I got a ? can I still do that even doe the motor was from japan? I know I know you guys are probably thinkin just check the motor stamp, if it says b20b its low compression, b20z high compression, but the guy who put in motor for him seems unsure also so let me know if I am able to check it...
