also in lets say b18c1 that would be a usdm gsr engine but a b18c would be jdm think of the letters kinda like families or series u have the D series,B series and so on

Re:Ideal Engine
 

ya JDM never used y8, z6, a6, c1, c5..

b18c1 = gsr here
b18c5 = type R teg here
b18c = gsr JDM
b18c Spec R = JDM ITR.

Re:Ideal Engine
 

so is a B18C1 better for FI then a LS/Vtec?

Re:Ideal Engine
 

b18A is 90-93 Integra
b18B is 94-00 Integra

B is the family of motor (dohc). 18 is 1.8 liter

Re:Ideal Engine
 

A B18c is just an all around better motor. But, there is nothing wrong with a built ls/vtec, other than a crappy stroke ;)
