what all is required to convert a 93 to 95 up style opti/tiimingcover etc.

what all is needed? i ask because im wieghing the options of going thru the trouble and having an LT4 ED timing set...i would like to dothis

but i need to know what is EVERYTHING needed for the conversion

thanks,

Jared

 

95+timing cover, 95+cam, 95+ opti. not sure if theres anything else, gaskets etc. the dowl pin may be ground i guess if you dont want to swap out the cam. cant remember if the 93/94 had a longer or shorter dowl pin.

 

ill probably just go with the stock chain and oversized cloyes gear for now, i know someone with it and its holding up pretty good

 

Never had to do it, obviously, so this is just off the top of my head. You would want a '95 timing cover (you can also use a '96+ but you'll need to plug the CPS fitting), longer dowel pin, vented opti, vacuum lines and check valves (one ties into the intake bellows and the other side would need to be tee'd into a vacuum source on the intake manifold), timing cover gasket/seal set, and of course your new timing set.

Oops, almost forgot about the wiring harness, you'll need the updated one.

 

that my friend is called a hassle

 

yeah something you should when you do a cam swap, since you have to swap out dowl pins. hell you got the timing chain out, you may as well swap cams.

 

thats why im considering all this mess, because im doing a cam swap

 

oh then make sure you get a 95+cam, a 95 timing cover, new opti harness, if you go with a cloyes true dual roller part no.9-3145 you can get a electric water pump, timing cover gaskets, and 95+ opti.


block off the water pump shaft hole if you go electric and cloyes.

 

i would perfer to go with the stock waterpump so im going with the lt4 perhaps

how hard is this conversion AND how much is the cost total?

 

conversion is easy, cost im not sure. depends on how muhc you can get the cover for, the new opti can be had from jason cromer i think pretty cheap. the gaskets you need regardless. harness i think can be found fairly cheap i assume with so many cars being parted out in the forsale section.


id say its a worthwhile upgrade.
