hey guys i know another fraud engine story but im just wondering the date thats stamped on my engine block is 9/1 but the rest of the engine appears to be a second gen engine the trany is a y21 with lsd, the harness plugs are grey not milky white, i know this isnt valid but the vtec emblem is bigger then DOHC it doesnt have that ghetto intake manifold like the sir1 but if no one is able to answer my question i guess i will know for sure when i plug the p30 ASH ecu into the biotch and it doesnt work.

 

sir1 has the dohc bigger than the vtec

 

the " 9/1" is stamped on the block or the head?

 

on the block sorry

 

The 1st SIR II were manufactured, and released in 91 as 92 models. Is there a big 2 post switch next to the oil filter on the drivers side of the filter? If not it is OBD1 (SIRII).
