My son's trying to figure out what generation his b16a is here's some pics maybe you can help us out

 

The head is stamped "90", so it's a 1st gen B16.

 

here's some more pics, I read if the harnesses plugs r grey then it's Gen 2?

The harness plugs typically match the chassis that the engine is installed in. Your statement about plug color only applies to the engine having the ORIGINAL JDM ENGINE HARNESS installed... what happens after the engine lands state-side means all bets are off. Since you have so many aftermarket parts, such as the intake manifold, it is difficult to identify the engine from the OE differences between the engines. The markings/stampings on the cylinder head are a good way to identify the cylinder head for sure... and if you remove the valve cover, the oil bars are a dead give-away for identifying the engine generation. Early B16A heads have CAST oil bars... the 2nd Generation (and Newer) heads have extruded aluminum oil bars.

 

do u have pics of the different aluminum bars? Do u have to take valve cover off to check?

 

Yes, you have to take the valve cover off. The cast bars are dull in color and slightly rough to the touch... the extruded bars are shiny and very smooth except on the edges. I don't have pics handy, but they really aren't necessary. Once you pull the valve cover, it will be OBVIOUS which ones you have.

 

If for some reason you are unsure... you are good at taking and posting pics... snap a pic of the head with the valve cover off and post it here. I can tell you which ones you have.

 

Ok thanks for ur help, for some reason this message was in my spam thats y i couldn't find my old post.. but thank u ill let me son know
