Collateral Damage- My 70 Chevelle site build

[Blown353]

I was planning on using twin ZL1 pumps on my car much like Stielow did on one of his recent builds, but depending on your system backpressure a single Pierburg CWA100-3 or CWA150 might move just as much water as the twin ZL1 pumps while also taking up less space, needing less plumbing, and having the ability to control their speed via PWM input... and it would be cheaper too.

Based on tecomotive's page with the current exchange rate a CWA100-3 with connector kit can be had for about $277 plus shipping, and a CWA150 with connector kit is about $226... that's tempting, I might have to sell my 2x ZL1 pumps and get one of those.

Nice thing about the ZL1 pumps is they're available everywhere though-- dealers, Summit, Jegs, SDPC, etc. The Pierburg pumps do have VAG part numbers though for OEM VW/Audi applications, so they should also be readily available.

Sounds like the way to go pump-wise, thanks guys.

Sold our house in California and bought a house in Medford OR to be by family. Dropped the car off Dave May of Genesis Fab in Galt Ca. to raise the driveshaft tunnel before the painter gets the car. Did a great job, super reasonable, and whipped it out on a day!

Good luck on the move, Jody.

My Inland Empire driveshaft showed up, and I was able to find an SS dash through National Parts Depot that actually uses chrome around the bezels and lettering instead of silver paint. Looks a lot better than other reproduction dashes. Started fitting the Dakota Digital gauges to the new dash.

Is your plan to cut out the original metal of the firewall and weld in the new metal or overlay this?

Thanks, Bill

I have already mounted the A/C unit inside (used weld studs) so the firewall cover was welded over the top. I did trim the lip around the original A/C section of the firewall so the cover plate laid flat over the top. I actually changed to a different firewall cover that has some bead rolling in it, fit well and looks even better IMO. I don't have any pics but it's this one.

I am using a CWA150 pump from Tecomotive. Tobias is very responsive via email in case there are any questions and the pump arrived in less than a week.

Jody, I saw this and thought about yours.
