Hello, I'm a newb to posting, but I've been using the site for research for quite a while now. Anyway, how do you tell the difference between a obd1 and obd2 ls intake manifold? I bought a used engine and I want to know which one I have. It's a b18b1 from a 97 ls, but I have a hunch that some parts were swapped around. Is there a difference? I'd appreciate any help here.

Thanks!

BTW, if egb18turbo is reading this, I sent you an email about some stuff you have for sale. I don't have permission to use im's yet.

 

the 94-95 ls and the 96-ones are slightly different. the 96-ones have the evap purge on top of the intake man. also the tbodies are slightly different.
