1996 Optispark
I need to replace the optispark in my 94. It's been through 4 water pumps and an engine replacement. Will the opti from the 1996 year fit directly onto my engine, or will I have to replace other things to get the 96 opti to fit?
Any help/insite is appreciated! |
Your going to need a different timing cover, different optispark connector, maybe a different cam if your's isn't drilled for the late optispark drive, long cam dowel pin, modify or replace the timing chain cam gear, and the later vacuum venting harness.

Any help/insite is appreciated! I suggest '95 Opti-Spark parts over the '96 because you can use your original crank hub. The '96 has a crankshaft sensor for the OBD-II that needs additional parts to put on a '92 - '94. Tom Piper |
A 95 timing cover and the vacume lines (Including check valve) are needed and thats about it. You will need to drop the oil pan a bit also.

Wow, it's not all that simple. Seems like the Delteq opti replacement may be the way to go...

You can vent the older ones, if that's what your after.

So really if its water contamination you are worried about the Delteq system helps nothing. You still have to have the opti and water can still ruin the cam sync inside of it. |
I'm not sure about the '94, but on my '92, the cam had to be changed because the hole in the front of the cam has to be large enough for the '95 Opti-Spark to fit into -- my '92 cam had a hole that was too small.

A simpler option is the dynaspark http://www.dynotech-eng.com/dynaspark.htm |
