waterpumps are worse on the N54 (plastic housing). They probably do break faster when the engine is pushed hard though. In fact the whole cooling system seems to last longer on the N52 (expansion tank, hoses, radiator, various plastic bits).
The N52 still doesn't have problems with injectors, wastegates, walnut blasting, and a bunch of other stuff. Stock for stock, it still has less issues. Sounds like your Z4 has been pretty good though? |

Compared to my first year with the E85, it's about on par. Typical BMW. Nowhere near the reliability of my "boring" Lexus GS350. I have not done much with the engine tune, no time and it's a really a hard engine to self tune, space and speed limits make logging tough. The car is really really quick. Weather has finally turned in florida and the top is going down more frequently again. The sound of the PE exhaust and DCT is just intoxicating. I finally bit the bullet and made an offer on a house that's 4.5 miles from work instead of my current 43 miles. That should reduce my vehicle expenses somewhat. |

An additional note:
To answer the question asked about how much power is enough for a DD, 330+ HP with over-boost is clearly more than what any reasonable person needs in a 3,500 Lb car. This is somewhat depends on the torque curve and the N54 produces full torque at 1,500 RPMs. Dammed thing pulls like a tractor. Just wish I had the throttle response of the N52. |

You can install larger turbos but the lag will be longer. Good for a glory a dyno pull but crappy to drive. I'm not interested in driving the small OEM turbos at crazy speeds. 200,000 rpm seems to be a practice limit for reliability. My tuning research has been focused on throttle responses rather than peak power output. We have the power, I just want it to come on quickly like the N52 did. Probably impossible but you need a goal to work towards. |

N55 platform is cooking right now. With the right mods/tune you can hold boost pretty much towards 6500-6800 rpm. No problems there. N52 note: We're about done finishing up my buddies ESS 330i n52. Lots of custom work done Will be posting videos this weekend on how it does against my car since he has a proper tune , full e85 etc.

I am curious though, do they share the same spray pattern as the n52 injectors??? I know I'm gonna do this and I had it in my mind that the s65 injectors were the go to in terms of matching spray pattern and all that jazz. Maybe I got mixed up with something else... : Also, who did the tuning?

Almost time for a dyno and new time slip from the track for me. I’d love to see some timeslips from one of the SC N52 guys. Seems like the most exciting things on this n52 forum lately are only on the SC front. Congrats on the house! That new commute is going to save you a lot of time as well, that’s like another 3 hours a week gifted back to your personal life |

Every reliability issue of the n54 has had nothing to do with the car being tuned or running meth. The block is sound, every other component is/was junk and most are not made by bmw. $1400 for 6 injectors 12 revisions, 1 revision per year, $500 water pump, eats coils and plugs every 30k, turbos were junk @ 80k but mainly fail well before that, etc. etc. Still the best bang for your buck if you can afford the maintenance. Name me another car you can buy for 6k with a MT AWD and make 400whp/450tq on pump 93 and 1k in boltons. Engine handles 600-700whp. The subaru guys would kill for an engine that does eat ring lands for breakfast and lunch.

Thanks for asking man.. luckily it was just a minor collision so my neck is just fine. The bimmer will need a new bumper, though.

Long time guys! How are your blowers running? Still really enjoying mine and just changed oil (2500 miles) and just slight noise at idle, especially when cold. But in comparison to my old 2004 SVT Cobra, this thing is super quite and soooo fuel efficient in comparison!
P.s since I forgot to install drain house, I pull from top now every 7500miles.
