I’m done trouncing this dudes thread - take it to the oil pressure thread if you feel you must continue but I would advise against it 🤦‍♂️

Tuning 101… I got to clean the coffee off my monitor after that one haha.

It’s pretty basic stuff.

If you’re going to tell people that a deep sump doesn’t help, have the data to back it up.

These cars are really good on the track, hit up the YouTube in my sig for some examples from in the car.

For a casual track car I would:

Maint - make sure the regular maint items are squared away - tires are of new vintage, belt, plugs, air filter, coolant full and rubber lines look to be in good shape, fresh brake fluid (use something good, SRF or Endless) pads, rotors, power steering fluid, radiators are clean and free of debris, fresh motor oil, good look over on the suspension for any worn bushings.

If you are looking to do some upgrades, I would consider the below:

UAOS and drain back - this will eliminate oil being ingested into the intake and allow you to run a higher oil full than is often recommended, the lower oil fill level is specific to combat the oil ingestion issue. With the UAOS with drain back, it is no longer a concern.

Tires - something with a 240TW will work well on track and street. I like Michelin road tires and loved my PS4S on both the street and track.

Brake Pads and rotors - I have experience with Hawk HP+ and Sebro slotted rotors and would recommend both

Suspension - this can vary pretty widely or be left out entirely depending on budget, if it’s on your list to get into - let me know and I will go more in depth here.

Engine - The lubrications system is a known weak point - I can’t in good faith recommend anything that I know works to resolve oil pressure instability because I don’t think it exists (opinion). Now I have data to show that the widely suggested deep sump and baffle kit from LN Engineering does NOT work for me (fact). The bright side of this is lots of people, myself included have tracked these cars WITH G induced pressure drops and been OK. Some people have not been so lucky - I would suggest you spend some time really getting to know this issue - you’re not new to modifying cars so I think you will like this thread, it’s a lot to take in but will bring you current with regards to this specific issue and just has a ton of good info from really smart people on how these engines work when used hard :

Got to go back to work - let me know if you have any questions and feel free to reach out anytime - any guy that ran idlers is my kind of guy ! Welcome Bro !

Really happy that you know about Idlers, I guess the guys from Speedhunters are making this thing known outside Japan now...
Since you are advertising your Youtube Channel, if you are looking for a bit of JDM track action, don't hesitate to visit mine : https://www.youtube.com/channel/UC42...gqLGw/channels

That being said I ordered my first Porsche parts today : an OEM airbox (used), with a brand new Air filter, let's start with the basics and ditch the K&N

The 996 was introduced in the 99 model year for the NA market, even though they were produced as early as 1/98 for the US market.

They weren't available in early 99. Your car should have yellow front corners on the headlamps aka fried eggs and standard halogen headlamps.

Move the headlamp dial one click to the right and pull it out to activate parking lamps and fog lamps. Two clicks to the right and pulling it out activates headlamps/parking lamps/fog lamps
