Fell down a Rabbit hole of mods to a good running car.

Recommended Posts

It all started innocently enough. I thought I would powder coat a few valve covers I had laying around. 

   That made me think it would look nice if the intake matched,  air filters should match too, then the thermostat housing and coil bracket.

 

 While the intake was off it seemed like I really should use one of the sets of Nissan Motorsport headers I have instead of the pace setter that are on the car. Then I need to fab up a new stainless exhaust system to mate with the new headers.  Next I start thinking I would like to do the cooling system mod for cylinders 3,4,5,6. I also felt like when the thermostat housing is off I would try to plumb my oil to water heat exchanger into the thermostat housing instead of the inlet of the water pump it had been plumbed into.

  With the new headers my under throttle body throttle cable system was all over the headers and needed to be redone. And so it continues.

 

I used a pressure regulator to put 10 psi in the cooling system so when the head was drilled for the cooling system the cutting chips did not go inside the head. This worked great. After each hole was drilled and tapped I plugged it so I could pressurize for the next hole.

The height I guessed on was perfect almost exactly flush with the roof of cooling passages.

I love a push lock fitting so I ordered a few stainless high temp fittings to use.

Test fit the intake take after installing the push lock fittings.

turn a nipple for the end fitting hose connection

All connected and plumbed into the thermostat housing

next comes the throttle cable

V1 of throttle cable was going to use a rod end for a housing mount at the throttle body. 9DAA69CD-8D4F-40EC-A08E-BF5E40F018F0.thumb.jpeg.e7fc7a535e2d90c5927eee267eb0384c.jpeg

while this worked it was crowded and not quite what I was looking for. While I think about another solution I turn to the firewall connection and try to improve on what I had used before. I wanted a stand-off so I could use a full length socket connector on the end of the cable instead of a cut down one. After combing the net for pics of possibilities I ordered what I thought would work. Not only did it work great but the holes were exactly the same spacing as the plate I had previously bolted to the firewall. Seemed meant to be.

after more searching I found a cable bracket that would attach to the throttle position sensor holes only problem was the cable mount was too offset from the bracket so I had to machine a new one to mount the cable as close to the bracket as possible.

Throttle cable finished. 

 

Next plumbing.

Oil cooler plumbing into the thermostat housing. It will be a tigh fit to get 10an flow into the thermostat-time sensor location. There is not much wall left but it fit.

i was one short on black 90* fittings so I will have to redo the other hose later.

Beautiful job overall, but that coolant rail is the best I’ve seen!  

I couldn't figure what you talking about, then I saw it, stealthy, no hot spots in your head. The throttle linkage is excellent I think, minimal hardware, clean. That goes for all the work you've done, that's going to be a killer engine bay.

I assume you are talking to me. The push lock have stainless barbs that dig into the tubing unless you press the release. They seem to grip the aluminum fine. You can see on the pic of the nipple I made where they have made a line in the other end. If I were to use stainless tubing I would have had to make a small groove for the barbs to catch on since the tubing is so hard. I thought I might have to do that with the aluminum but they grip fine. The other nice thing about them is they swivel so you can remove them if needed with intake & exhaust in place.

I am talking about the “rail” itself.  Is it hardline, or just grey coloured tubing? The line between the T fittings.

Aluminum tube. Just pushes into the tee fittings. Could be stainless, plastic, aluminum. No flare. Just cut and chamfer the end so as not to hurt the o-ring when installing. 

Sorry for making you state it twice. I think I have my head wrapped around it. It would have been easier if I had ever seen a push to connect fitting before.... but then I searched the pricing on stainless fittings.... photos may be as close as I ever get 😲

Things start getting really tight whenever you ad to the systems . Just went thru this on mine with similar projects . Like the push to locks.

Im waiting for leaks to happen during first fire up -lol

What cam sensor is that? Jeep?

Made some more progress on the exhaust today. Some of my welds started to look better. Some did not. Should be finished this weekend for sure.  What kind of welding table do people use when the exhaust sticks out 4’ One direction and 2.5’ perpendicular to that? I suppose they can weld pretty at any angle standing on their head. I can’t.

I did do all my welds today without dipping my tungsten in the weld and that was nice.
