So my 94Z has around 107k miles and symptoms of a bad opti. I just want to make sure I'm getting the right stuff. I know most ppl would recommend the MSD unit but I plan on keeping my car for maybe another year then maybe selling it so I don't want to spend tons of money on the best parts in the world. (Unless some1 can convince me to get it)
Here is the only other non-vented opti besides the MSD I found.

and of course I heard around here more than once that I might as well replace the waterpump.

I heard you can't skim on the water pump because it will destroy the opti if it leaks, so I don't want a cheap Duralast one for $48
Are these the right parts for my car I guess is what I'm asking before I buy them online.

 

I haven't had any experience with the Summit opti, so I can't say. Last summer I replaced the one on my Vette with a new MSD, but I got a heck of an ebay deal on it.
I wouldn't want to spend $500 on one otherwise.
The water pump you show is for a Vette (pipe fittings/outlets would be different), so that part #'s not the right one for your car.
I put this brand on my car: http://www.summitracing.com/parts/GMB-130-7100/ and it's been doing just fine, not to mention being $80 less.

 

Lol, didn't notice it was for a vette.. Has anybody had any experiance with summit racing opti before? I hope they are descent.
