I won't debate Subaru's poor H4 reliability history with blown motors. I've owned a number of Subarus over 20+ years including currently a 3.6R Outback (closing in on 9 years of generally trouble free ownership), but let's do keep in mind that this particular owner is taking the car on fairly aggressive road courses and is running aggressive Falken RT660s and a quality suspension. As such, this car does generate higher peak and sustained Gs than a stock BRZ/86.
A M235/M240 that sold for $48-55K new isn't really fit for track duty outfitted like this either and needs oiling upgrades, especially the M235 N55 which ideally needs a $2,500 installed S55/M2 N55 oiling sump setup. My stock 2011 Cayman Base with a 2.9L H6 is up to the task of heavy track usage, BUT it has a robust dry sump system with 4 scavenger pumps and holds nearly 8 quarts of oil. This car sold for $65K back in 2011; that's $90K in today's money. I see mention of the amazing S2000 as well but also keep in mind that car sold for the equalivent mid $50's in todays money. In comparison, the BRZ/86 is a lower $30K car in today's money and the FA24 has a small pan and quite a standard oiling system. It's a shame Subaru didn't at least increase the pan capacity and add pan baffling. I'm sure KillerB will figure out a fairly easy solution with an upgraded pan. Cliff notes: It shouldn't be overly surprising that a lower $30K car doesn't have a oiling capacity to handle track work on more aggressive tires and suspension. So few owners use their cars this way anyways. Those that do should be prepared in prepping the car appropriately for track usage including brakes, cooling, and oiling mods.

the ones that sold for 38-39k are actually 68k today ... it was an expensive car for the time... i remember this was when the accord was $16k at the dealer... a civic was 13k

I've heard this false equivalency for years. Back in 2003, when WRX STI's were crapping out their blocks in the middle of the track while the cheaper better built Lancer Evolutions were setting lap record after lap record. And E46's were tooling around track at full throttle all the time and not crapping drivetrain parts out their exhaust pipes. I don't understand Subaru's apologists. I had to install the Forester Turbo's oil cooler on my BRZ to keep the oil at temp ON THE STREET. I mean BMW has had its hiccups, but Subaru does this over and over and everyone forgives and forgives. Shawn |

As far as I'm concerned, all bets are off with most any sub $60k car if you plan to take it to a true track with sticky rubber. I figured it was an obvious thing that for most cars you need to do cooling, braking, and oiling upgrades if you want to race hard/competitively. |

I understand if you’re trying to win a pro race series. But four 20 minute sessions a day driven hard? Maybe after a few years. So under the “race hard” circumstances you’re right Shawn . |

I had a 135i I just sold with 230,000 Km. Had wider RE-71R tires, ST coilovers and it was very low and it was stiffer, with an H&R front thick (thicker than an M3’s) sway bar. MHD Stage 2+ on original turbo pushing all the boost it could… It was on track whenever I could. Never had an issue with the powertrain. |

I remember the good ole days where manufacturers would just throw more oil at the problem. My 1987 924s had a 7 quart sump.

I've been on this forum since 2015 and have read a number of accounts of tracked M235's (and 2014+ 335s) spinning rod bearings on long, high G-sustaining sweepers. There's good reason why the OG M2's N55 uses the same oiling system as the S55. With that setup, which is plug and play, you're golden for track work. Of course, with all the cost needed to get the suspension right in the M235, it makes more sense just to buy an M2 as it has all the right parts from the start.

Most of the 2011 up 911's are between 7.5 and 9.7 liters (a little more than a quart per liter) Shawn |

Well yeah, but those cars are circulating oil through turbochargers and part of that is to remove and manage heat, so more oil capacity isn't necessarily being used just to deal with g-forces and engine lubrication in those examples.

But the 911 GT3 isn't, I think. Still has an eight quart sump. Shawn |

Can't be 2011, you had the 997.2 in 09 and 991 in 12 so not sure which you're referring to.

Oil Pan - Porsche (9A1-107-032-75) is the oil pan and is listed as fitting 2009-2012 911’s in the parts diagrams. I cannot find any reference to a larger pan from 2011, doesn't mean it doesn't exist, I just cannot find it.
