New oil pan + Adding an EGT probe to a turbo manifold // Random fab work

[480sx]

I bought a new oil pan for my build, and installed a bung. Figured id share a bit. Also added a EGT probe bung to my AMS manifold.

So i used the JGS bung, and a brand new OEM oil pan($110).

First, as i did with the last pan i made, i wanted to create a downward angle for the oil to flow through. This was done with our mill. Its actually a pretty cool shot cuz the mill was spinning when i took it.



This is the end result with the JGS hose barb fitting, and the pan that the work was done on in the background.



This is the bit you really want to use for sheet metal, it gives you a perfect cut every time. Drill a tiny pilot hole or use a spring tool to punch a center mark, and your set. Hole drilled. I picked a location thats probably to far forward for a non modified AC bracket, but i dont ever plan on running ac on this car so i dont care much. This spot also allows me to use all the bolts in the oil pan. The other one blocked a bolt hole, but allowed me to keep AC and was perfect. The old one never leaked either but w/e.



My bung is excited! Well in all actuality it was takd into its final place. Two beads were placed on the outside of the pan-bung for strength. The sealing bead was done from the inside.



This is the inside of the pan. Looks pretty horrible lmao, but you have to know what to look for. The 'ugly' parts is from the penetration from the outer welds that were done strictly for extra strength. The inside lip weld was the 'real' weld that seals it. I cleaned up the bubbled coating and its good to go.



Moving on. So iv been wanting to have an EGT probe on my car forever. For this build, i went ahead and modded my AMS manifold so i could run one. This was as simple as drilling through a 900 dollar manifold and welding a bung to it...

Cylinder number 3 runs hottest on a Ka im 99 percent certain, so that was my choice for the bungs location. It took us a bit to figure out exactly how to mount it, but we came up with a location and, well, had to start somewhere.

Heres my new 900 dollar manifold.. This was done with a spring tool center punch, then just normal drill bits.



The next part was a bit tricky. We had to make the little bung fit pretty snugly with the pipe. When tig welding, you dont want a gap thats bigger than your filler rod, and thats what we ended up with. Here is the bung in its final position tacked on. Somehow i didnt get a finished pic, ill get one up eventually. The weld turned out perfect, even though it was a really difficult place to get the torch in.



The root of the weld. It might be a bit difficult to see. You can see a lot of AMS's roots, which are generally perfect. The key when tig welding stainless steel is back purging. If you dont backpurge with argon, the molten metal reacts with the O2 in the air and ignites it causing a, bad weld. The root will appear black and burnt, with pieces dangling out on the inside if you dont do it right.

Wow.Sweet welding.I also want to redo my oilpan so I can angle it down, but too lazy :P.

The part where you drilled the manifold had me scared haha.

So..how much power are you trying to make now?

[480sx]

Im only gona run about 18 psi max on 93. Anything past that and im gona run meth, or possibly E85(both of those are the main reason i wanted an EGT gauge). Ill eventually max out my s258 which should put me real close to 600. Thats all ill ever try to make with a Ka.

That's all?

Most of the time when you see threads that say something about 500+ horses in KA-T it's a crazy noob. But you sir are going to have an animal of a car.

And +1 to you for having the balls to operate on a $900 mani!

Hey what is the benefit of having the EGT on the manifold as apposed to the down pipe? Maybe im just answering my own question here but is it beacause you get a reading right out of the engine instead of after the turbo?

[WDRacing]

The real difference in placement is the delay in temp changes reaching the sensor. When tuning for high hp you want to know right away if things get to hot. If you wait for the hot temps to reach the DP you could be F'd already.

Beyond that there isn't much difference so long as you adjust the temp readings some for distance and cooling.

What did you do about a downpipe 480? Pics!

[480sx]

I know Brian, i cant f***ing wait to add some Meth and tune this thing out. E85 isnt really as realistic of an option as i want it to be for a DD/road trip monster, so im thinking along the lines of 93 + Meth.

Eventually im going to sell my Enthalpy tune and get a Nistune board, cuz im DIY till i die. I know Cory had some success at my desired power level with simply a Enthalpy tune, meth, and SAFC, but im looking for a little more.

WD's pretty much dead on as far as the EGT sensor question goes. The closer to the head, the more accurate the readings of true EGT's are. If your at the DP, you have to assume or guess that your actual EGTs are higher by idk.. Some magical number equaling the temp drop through your manifold and turbine. In addition the lag time might be enough to melt a valve or w/e. My WBO2 system has a built in engine kill switch for different complex variables.. Say... 18+ psi of boost and 900C, or leaner than 12.6. Just giving an example. Really need to learn lambda....

GTR - I havnt made a downpipe yet. My last build i didnt even use the AMS manifold, i used the modded boost designs manifold thats now actually sold to a customer, along with the DP. This build im gona use it, so i will have to fab up a new 'down pipe'. Although, with the AMS's manifold turbo position, its not really going to be much. Im going to use a 5 bolt flange, with a 2.5 inch to 3 inch expansion pipe, to a V-band fitting, then attached to my midpipe/cat assembly. Ill get pics up when its done.

Good placement of the egt sensor.....cyl #3 is the hottest running of the four. Giving up is not in your vocabulary is it?

She'll be a beast when done

[WDRacing]

Lambda is easy bro, when injecting the meth try and keep the levels at .8

[480sx]

Giving up is not in your vocabulary is it?

Lol not when it comes to one of my main goals in life. Sht iv wanted a turbo 240 since they were still in production..

Saved that chart. When i get it up and running im only gona use lambda and learn it. Charts definitely helpful.

End result





Little bit of undercutting, but not really much of an issue.
