How do you tell what type of engine you have ex. gsr,gs,ls....etc.

You can tell by the engine code. If your integra is a 92 there should either be a b17a1 = gsr or a b18a1 = ls/gs/rs

where would this code be located

It's on the left of the head... but look at your engine and see if theres a valve cover that sais DOHC VTEC ... if it doesn't then u have an ls/gs/rs engine b18a1
