The oil surge isn't generally what kills the engine. The oil surge slowly kills the oil pump, then the poor condition oil pump is what kills the engine.
Make sure to keep an eye on your cold and hot oil pressures (via oil temp). This will indicate when your oil pump is beyond help and needs to be replaced.
If you're currently 85-95 psi oil pressure at 80ºC oil temp, when your pump is dying it will go down to 75psi, 70psi, 65psi etc etc.
Of course you post this 2 weeks after I ordered my Racefab sump. Great info though. Keep us in the loop!

No doubt its a bandaid, but its the best option before going to a dry sump. A dry sump is the REAL answer for the track but most including myself like to walk the street car line and keep it simple. If I was going to track my car extensively a dry sump would be the move to save engines.

If that pan is good enough for Balrok with R comps and aero, its good enough for a street car with 100-200tw 255's IMO.

eflove , I'm in the same boat. I'll purposely run an 100-200tw tire at the road course to avoid oil issues at my skill level.

Mike, was it you I was talking with about the oil pressure bypass? Trying to remember who it was so I wont spill any beans if its what Im thinking about.

My solution should (fingers crossed) bridge the gap between the Racefab sump and a dry sump setup.
At the moment there is about a $4000-5000 split between those systems.
The Racefab sump (or Moroso) should be the minimum for any fast street car, it just doesn't cut it on any right hand corners (circuit use).

I wouldn't have any issues putting a dry sump on it at this point. Believe it or not the thing that holds me back is having to remove the AC to do so. I think a pan with a accusump will be just right for now.

The Norris Designs dry sump kit has an option to retain A/C.

Hooly moly, much respect to keeping the exterior subtle when so much talent and creativity went inside. I'm not surprised you have an Integra av. Some things just age well, like simple purposeful lines. Really happy to see this platform being treated right.

With my free time this week I addressed some issues I found at super lap. I took some photos of things I found so I figured I would share.

The combo air temp/pressure sensor on the hot side melted a bit. trimmed it back a bit but will probably plug this hole in the IC pipe.



You can see where they mount in this photo. Awesome to see how well this tube and fin IC is working.

These tabs seem to be lacking from every aftermarket IC but are needed to retain the stock undertray correctly.


The motor was moving around just a bit too much on track. Added a front tq mount and was nicely surprised how little NVH was added.

Lots of tabs again to keep the stock under tray mount.


Oil control was a issue on track. Moved the rear port to the side of the valve cover in hopes the increased baffling will reduce oil getting to the catch can.

Oil pressure was getting to 20 in the right handers. Accusump to help with this.


Bulkheads at both ends of the car to make service easy. I went with -8 line after seeing the side of the port on the filter housing. We'll see if it's big enough. Used push-loc for how thick and robust the hose is vs other options.


The PC on the muffler didn't hold up to the heat. I expected this but wanted to try it. Went with cerakoat this time.


Grabbed some waste gate blankets from PTP turbo.

Now that I don't have a class rule book to think about I installed my SSB RLCAs. Far less movement.

Beautiful execution.
Also, OEM heat shield is a great way to make the attractive engine compartment functionally cooler and cleaner.

So you installed SSB trailing arms: are you also going to use the uprights?
Hope so. Your driving skills, and already wonderful package, deserve optimized chassis package.

I loved your video at COTA, although not the fastest way going sideways, your skill and car's ability to be driven that "fun" way.

Hey @eflove
Check out my post on the oil system below:
https://www.evolutionm.net/forums/ev...r-why-how.html

Also that Accusump plumbing - you've gone into the non-filtered port on the oil filter housing. I'm not sure if that will cause future problems with the accusump seals.

Also - ultra fast response and high temperature air temp sensor here: https://hv-electronics.myshopify.com...esponse-sensor
I use two of these on my setup and i've seen 180ºC without problems.

Been a bit but I did take the car to the track one day this weekend. Low boost (500 or so) but still a blast to throw around.
