... okay so i knew about the different optis about there cause of the different styles of timing covers. is there any thing different about the blocks? what is the scoop on running a double timimg chain thing .... i have never looking into this stuff ....
also if i get the 95 and newer style timing cover and opti will it plug into my 94 car and work?
'93 was a one off year with a spline drive opti which requires a an OE chain set. '94-95 used the same cover and opti and driven with a dowel pin. '96-97 are essentially the same cover as the '94-95 except they have a spot for the crank sensor. The opti is the same from '94 up. You will most likely need to clearance the timing cover to use with a DR timing chain, but I know they make them for the later years.
They changed it in 95' not 94'. The 95-97 cover is different and the 95-97 opti is the vented style. *note that 95's dont have a CPS like 96/97*Quote:
