Some parts on FCP with the lifetime warranty keep the prices down if you go through consumables fast. If the 328i is strictly for tracking, next time I would suggest you get a set of 200tw tires like the rs4 which should hold up longer than the ps4s on track.

Your N54 should have an extended radiator and oil cooler at the track.
Also make sure your IC is blocking your radiator to a minimum. Your gearbox and engine will love you. Ow ja also code out any nanny, minus ediff. Because it will cause many issues on the track, like brake fade torque reduction crap based on calculated measures instead of sensors..

I can tell you that oil cooler for 335 in N52 resolves those issues as I track car at 5,000ft. |

My wife is taking my girls to see the inlaws for a month in August. Hopefully will do a track day with the e92 then and get a good feel for how this car can do on track. I can already see this car getting a half cage before she gets home and tells me no... |

Sorry, thread is a bit old BUT it is an interesting topic of conversation. Esp
It is true I see a lot of e90 and especially e92 M3's but not too many non-M's. Despite having a lot of potential as a fun track car. I think it has a lot to do with the type of people who bought them new. They are ten years old which is not new but not super old. Many may still be with original owners. People who spend $40k on a brand new non-M aren't necessarily thinking of tracking it right away. Or if they we're, the $40k would go a lot further on something late-90's with track mods. Whereas the M3 was designed to handle track duty right off the dealer lot (for the most part) and the type of buyer is more likely to be thinking about going to the track. Does that kind of make sense? That's my hypothesis at least lol Edit: Shoutout to edycol for ripping around the track on the daily grocery getter snow car kid hauler. One car to rule them all. I love and respect that. I have similar plans myself. There will be some DM's in the coming months lol.

N52 on its own doesn't create a lot of heat. No turbo, no direct injection. It is reliable power plant. IMO best E90 for track if fun is only priority, not being fastest, is 328. |

Today I was very pleased with the turnout of e9x cars. We all parked close too. Next to my Alpine White 328i was a 2011 BMW 335is Alpine White with Oyster interior and DCT. 60k mile car....amazing. Couple cars down was a 2008 (I think, maybe newer) carbon roof M3 with DCT and 80kish miles. Also Alpine White but w/ black interior. That dude was RIPPING it! M3 had no problems but hasn't done rod bearings he says..and the 335is guy kept getting CEL and weird vibrations after a couple laps. He cashed out after the 2nd session and a total of 5 laps to live and fight another day. My car was great - oil gets hot but not overheating, and the brakes started to get hot but all in all no complaints! In short, this thread needs kept alive because there IS a lot of protentional. The local track for me has an oval and part of the road course is the fast wide oval and my bone stock 328i carries roughly the same corner speed as a supercharged 500ish whp Camaro I rode in. Short walkaround video of my car and the 335is linked. The M3 is in the first few second in the background. In the middle is the 180k mile black e46 M3 |

I would at least install heat exchanger (fluid/fluid box). Though oil cooler radiator type would be best. |

If I was a bit less aggressive with my corner exits and just held third and lugged around 3,000 rpm out of the corner then the temps were barely over that 250 mark. Long term that is the plan, and also running water instead of coolant/water mixture. Some guys at the track recommended that for better cooling. |

Go oil radiator. I didi it and I can stay pretty much forever on track and track I go to is at 5,000ft. It is overkill and you want that. It is good for engine! Don't worry about winter and warming up. Thermostat opens at 110c. As for coolant, run 10/90 or 20/80 ratio coolant/distilled water. You want bit of coolant bcs. lubrication of pump. |

Next season I have my eyes set on a e90 330i 6 speed to gut and set up proper. THANK YOU for the coolant advice.. 20/80 sounds perfectly reasonable to me - and for the oil cooler I agree with radiator mount. I researched the 335i oil cooler and it seems like a piece of bubble gum on a water leak. Anywhere I can go to see your setup? |

Seems like the e9x generation might get skipped over entirely by the club racing groups.
Local BMW club is about 50% e46, 35% e36, 10% F, and 5% e9x. Ignoring the oddball old Mercedes and other unique pieces. It's odd that there are more F cars than e9x, although the F's are usually big money teams. e36 are aging out and getting harder to get engines and body parts for but the e46 has another 10 years to go and is a lot lighter than the newer ones. The n52 cars will be skipped entirely. Too heavy compared to e46. Direct injection valvetronic turbos take a lot of work and money to turn into race cars. By the time e46 age out the F's will be 15-20 years old and might be the next logical step. Not sure the e9x will ever get much club racing love.

There are others who did oil cooler. It is direct retrofit as oil filter housing is same, just has opening on the side for heat exchanger or oil cooler thermostat. You can find on google more photos. [IMG][/IMG] |

One more thing: run heat! Run heat at max temperature and ventilation at full strength. That will serve as basically additional cooling radiator. Close all vents except those on the side and turn them toward windows which I guess are open during track day.

Because everyone is skipping over the NA e9x cars they are CHEAP fun on the track. Many can be bought well under $10k. Most guys I talk to at the track paid $16k on the low end and $20-25k on the average. Bolt up M3 suspension and 335 brakes and you have a fun haver.. Personally, I'm all in on the chassis. |

Spec e90 would be cool. clapped out 328's are just being driven into yards to strip and crush for scrap metal.
Keep the block and most of the engine sealed, bigger radiator and oil cooler, keep the 328 suspension bits, limit tire width, allow bigger brakes and camber plates, bushings/shocks/springs/bars open. Not sure what to do with the ABS/DSC. It's easiest to just yank the whole system and install a brake bias valve, but peg-legging out of corners really sucks. Perhaps scrap the DSC entirely and allow rear lockers? I'd imagine some enterprising coders could even write a spec-series flash for computers.

I love that there seems to be more interest in this then expected. I have to keep myself from strait up stopping the e30 build and just turning my e92 into my track build.....Parts are so much easier for these cars and you don't have to custom make literally everything, lol...

The n52 is a bit slow not the best power to weight.
The n54 has oil starvation issues, as well as cooling issues, as well as many other issues. The S65 is the only 'real' choice for a track car. For all of the reasons said above by other people. Looking back I should have just bought an m3 and supercharged it.

Three-stage intake and AutoWerke flash can get you N52to some 260-270hp on the crank. Some more serious modifications, like modifying N54 intake, MILV's, headers can get you probably close to 300hp on the crank. Boca has approx. 260WHP on his vehicle. Yes, M3 is track option, but rod bearings? |
