That's the next leg, after the mounts. Haven't really got it all dialed in yet.

Auto Dynamix is currently remodeling the building for a new show room. Currently, work is not being done on the car because I'm helping my buddy build the show room in my free time. Burn out set in on everyone so I found a few minutes to work on my car . Slackers!

Who am I fooling, I didn't want to work that hard on the shop...

I stood around the car during some down time looking at how the cooling lines would run. I ended up mounting my Motion Raceworks overflow catch can. It had the option to be mounted with bolts... but I have a welder so I welded it. lol

The Davis Craig was pump was going to be mounted on the drivers side but my buddy said it has to push on the cold side; however, I did get the specifics correct. The pump has to be lower than the radiator. Placing the pump lower will ensure that no air gets trapped and avoid cavitation. Flip side of that, the filler needs to be higher than the system to let all the air out (this was what Rusty was getting at in an earlier post).

I had to edit the last post because it was not even readable. I rushed to get a post up... lol

gbrettin · 08-26-2020, 09:46 AM

The catch can was mounted to mirror the overflow tank. My vision for the build is really taking hold now. Low mount accessories, chrome and black theme, and symmetry (as much as I can).

I have all the Fragola fittings coming for the coolant system and an in-line fill (already here). Unfortunately I forgot to order hose and fittings for the catch can. I should have enough to keep me busy anyway. Motion Raceworks is crazy fast with their shipments.

gbrettin · 09-01-2020, 01:39 PM

Fragola fittings came in for the radiator. I had no idea how large -20 was until I saw it in person. -20 is 1.5" while -16 is 1.25". The size of the fittings and hose had me searching for ideas for a while on the best way to route the hose. I took a few pictures along the way thinking "AH this is how it's going to work." BUT... like plumbing, things change. I left in some of positioning photos just so you can see the process I used. Something I don't often mention are the trips to the hardware store so I threw in a picture.

The inline fill ended up working best using a -16 female coupler right off the water manifold. Word of advice for people messing with fittings, think plumbing (that's why I keeps referencing plumbing). Unions and couplers are available with AN lines. Also, all the AN flare fittings need to plug into ORB fittings. That may be helpful for someone because I saw people going from AN flare to NPT fittings which causes leaks. The picture with the pump facing up shows an ORB fitting (-20).

I made a video on IG@gbrettin of how the plumbing routes. <- click to see

With all that said, a bracket is needed to mount my Davis Craig water pump. This really took a lot more time than intended. The bracket came out great but I had to cut small pieces out, grind them down, weld them up, grind them down, reweld and then do a final grind. The placement in the one of the pictures below should get the pump to the lowest spot. As mentioned before, it's to prevent air being in the pump.

Well crap... Doesn't look like I got pictures of the fittings. They are just on the parts or scattered around the car.

You are are sure doing a good job of documenting everything just in case someone wants to follow you in doing stupid! They will still be stupid but well informed!!!!

Yeah, I really like doing all this but I think people get confused with what it goes into making a build vs fabrication/build vs build/fabrication/swap. I think all three of those things are uniquely different. Unfortunately, my mindset was "swap" only. I'm a firm believer that a swap is WAY more involved than what people let on.

Also, I really hope someone can learn something from this.

Agreed! Mine is fabrication build, Spooler is a motor build and they all stupid endeavors. I here a lot of people talk about a motor swap because you can pick LS fairly cheap but that is where that ends. The rest is money!

Mission accomplished! I learned not to do a swap

The flip side is if the swap is done right LS reliability!

Most LS swaps consist of a 500 dollar junkyard engine, gapped rings, cam and a turbo (maybe). If people want to make power, they grab the gen4 stuff. I could have done all that and made 800hp all day rear wheel. Heck, my buddy with the twin turbo G8 made over 1000whp doing the items I mentioned.

Personally, I don't want anything to do with the junkyard engine scene (although my block technically is). Heck, I think I would do the same lunatic build if it was a 2J, RB, VQ etc... overbuild to the moon. I literally did the same thing to a moped I rebuilt. When it was done, I tested it out. My 1984 QT50 that originally went 20mph went 65mph on a 65cc engine.... it was terrifying. The shocks were not upgraded and neither were the brakes (it's getting detuned). Point being, I feel like this is just what I do. Although, I'm attempting to make my car somewhat well rounded.

Not sure if I mentioned this or not, but I will be using CO2 with my waste gates MS3 can be set up with CO2 to make the driving experience mild (gate springs at 3lbs) to wild by holding the dome closed on gates to build 40lbs (aka holy sh1t mode).

I like the idea of a Corvette but I would never own one. I LOVE the way a 370z looks and I always find myself drooling over the bodylines, even to this day. The devalued state of the 370z, American muscle and experts that I can lean on for my build made it an easier choice.

Short story... I'd be up to my eyeballs in any direction.

Bro, what you're doing is actually legendary. Legitimately inspiring.

It's not often you get a chance to see a build like this from the very beginning. And to see everything. From the progress to the set backs, and working through them.

A build like this boarders on OCD and lunacy. You learn about how to do things plus you learn about yourself.

Part 1

Well. I made a bracket for the water pump. I've got to say, it was a real pain in the d1ck to make. It took about 12 hours of paper cutting, welding, grinding and painting to produce the bolt on portion to the car. I have the Part 2 pictures but the photos have not sync with my photo share for some reason. I'll post those later.

Not entirely sure what to say other than it really was labor intensive to make an angled bracket. My buddy with the G8 said he used aluminum and bent the metal. Not sure I would recommend my method to anyone, although I like the result.

Looks like I may have to swap the -20 straight connect on the pump to a 90 or possible a 180. The hose either needs to run at the top of the bar or at the bottom. I think I'm going to try getting the hose lined up at the base of the V on the radiator. I think I made up my mind while typing the last sentence out. That's not a great approach while buying 30 dollar connecters btw. There's two -16 connectors I haven't used and I groan every time I see them. I'll try to find a use for them later.

gbrettin · 09-07-2020, 11:36 AM

Part 2

I had to pick up some rubber isolators. A fella that I know, who also uses the same pump, informed me that the pump fails if it is hard mounted. Luckily, the hardware store was right on the way to the shop. Disaster averted. Davis Craig water pumps are not cheap.
