Just stumbled across this on Craigslist. Not sure it’s what it’s worth but I’ll post anyways.

Yep. No problem. From the ad it sounds like he may even have 2 of them.

6mm elements vs what 5.5?
Plus it sounds like it was all rebuilt - not bad!

Yes, 5.5mm are standard for the 603 pumps.

I'm curious... what are the power and efficiency differences between the 603 pump's 5.5mm elements ant the 6mm? I'm 606A project retains a completely factory setup with the 603 pump (so 5.5s) but I'm not trying to make a monster... just something drivable and efficient with a turbo pushing 12PSI.

Drew, do you want a tricked-out G that drives like it still had the 617? Okay maybe a little better than that. 6mm elements give ~9% more fuel, which might be enough - should be at least as good as a factory 606 setup.

I have a pump getting the Goran treatment, finally, and will see how much it can be dialed back for efficiency. I'm tired of pushing my foot through the floor only to maintain freeway speed. I've tried almost everything else.

Interesting... even with the 606 swap? I've been fortunate to drive G's from the N/A 617 (mine) through the 606DT LA pushing 300hp. The latter (with 8mm elements) is more than I'd ever need or really want, but I haven't hit much of a middle-ground. Cole's N/A 603-powered W463 SWB is just as slow as my 617 was in my W460, but one also has to account for extra weight there. I'm fine with giving my leg a bit of a workout, but I really want to be able to merge onto freeways without fear that I'll be killed by a semi truck. That plus slightly better fuel economy with a 5-speed is all I'm really going for.

I found the factory stock unmodified 606 to be pretty good for the Autobahn in a SWB
