Do I really need a LSD?
I'm looking at getting a 335is with a JB4 on probably the auto map, downpipes and a DCI intake.
I searched and find al these older posts ~2013-2014 about car not having LSD and some people asking. Some say it's fantastic first mod you should do some say the ediff is enough. Now that we are in 2018... is it still fun without a LSD or with those mods it's required? I won't track the car but I will have fun with it. |

The car is definitely still fun without it, but it will make the car more predictable and better to drive in certain situations, especially tracking.

Definitely will not make positive difference unless you are very good driver to utilize the LSD. Most of us simply aren't and LSD will make the car more difficult to drive. I tracked mine for 4y on open diff, over 40, maybe 50 track days. Now I have LSD and re learning how to drive the car.

I'd add a better FMIC & 1.75" silicone inlets before I added an LSD Also, double check to make sure that JB4 will clear the CEL codes that the car will make with downpipes. |

I will use the car in winter but I don't DD all the way to work I usually drive to the bus park. But on the subject, I thought a set of good tires would be good enough, even without LSD. So I'm not sure if people are overreacting here trying to drive up a hill full of ice in summer tires or not. |

LSD would be absolutely not necessary for that spirited driving. Spend your money on other upgrades. Or just save your money.

Just gotta find that one 335is... they are damn rare. While we are on the subject of the car. Is the 6 speed or DCT better to handle more HP than stock? |

If you get the DCT, it might limit you with transmission type flashes such as the Alpina flash. I don't think the 335is is all that rare. In certain colors and with certain equipment yes. Look into the 2011, if you want to save some $$ or if money is not an issue get a 2013. You should be able to get a 2013 with under 40,000 miles on it pretty easily. Personally, a car like that, I'd only buy it from a dealer. Dealers only keep and sell trade ins that are in good/ great condition to begin with. All other cars get sold to auction. If you don't want to pay the dealer price, at least pay a reputable dealer the $200-50 to have the car checked out before you buy it. |

In Canada they're not very common we can say... not a lot will pop up for sale by BMW dealers either. I already planned on doing a PPI from somewhere good if I went to buy from a private dealer for sure. In my budget the mileage seem to be differing a lot. There are some with 60 000KM and some all the way up with 135 000km in similar price range. |

I'd be using apps on my phone like Auto trader daily. DCT trans uses Pentosin as a trans fluid. Not cheap....just an FYI...... I always liked the Lemans Blue with that car. That's a rare color, for that car in the states. |

That's good to know, I'll prioritise manual then I didn't have a driving preference between the 2 but the one with easier maintenance, cheaper and easier to take hp would be the one I would go for. Might install LSD and do a crazy build in the future who knows but for now base jb4 is what I'm looking for in terms of HP in a car. Lemans blue wow not a bad color. Altough I would prefer it more vibrant! White is my fav color for the 335 |

Wavetrac - there is a good diy on YouTube for this one. It's basically the same process - $1300.00 by itself. Has fairly good track record or reliability almost equal to Quaife. Quaife - claims to have the best longevity with fewest repairs etc of the 3. $1500 by itself. Extremely reliable. With a stick shift, you won't be able to do the DIY by itself. You will have to send it in to have the weld broke from the gear. You need to read up on this. It's either that or you just order a pumpkin with the LSD already done. This will add about $1200.00 to your cost making an M-factory pumpkin with new diff bearings around $2300.00. With a DCT, I don't "think" they have a welded diff. Pros & Cons |

You are right on the change interval. You don't technically have to change the OEM Pentosin until 100,000 Miles and then maybe every 50,000 after that going forward. It's just like $15-20.00 a quart vs $8-11.00 a quart. No issues... I learned something more today... |

1) OFHG 2) VC 3) Front Crank Seal 4) Rear Main Seal 5) Oil Pan Gasket 6) Megatronic Sleeve. I have changed all of these on my car. Items "around the car" would be items like the water pump & thermostat, or turbos (wastegate), injectors, etc. When looking at a 335 (n54), between 75,000 miles & 125,000 miles you are going to be doing a lot of work on it, in order to keep it in tip, top condition. I have replaced the injectors, the water pump & thermostat. My turbos are OEM w/ 153,000 miles on them and run strong, after I fixed the wastegate rattle on both turbos. I don't know how long they will actually go, until I have to actually replace them. My best guess is maybe another 30,000 miles or so. Brakes last a long time on BMW's and shocks & struts have normal longevity (around 75,000 miles). My best advice to you would to by the 335is you want. Drive it a year and then start to do upgrades. You are going to want to get familiar with the car and begin to start to change out items the typically wear out or just need to be replaced at certain intervals. Having a work history accompany the car from day 1 would be gold. You probably won't find that unless you are buying the car from the original owner. There is a laundry list of items you want to be fairly new or brand new, on the car, before you do a tune or you will run into problems. |

But I do plan to DIY most things I can do. *cough* e9x M3 *cough* Haha but yeah, if the motor are solid, and the N54 seems to be, with that modern 2jz nickname is good to hear. I'm really happy to hear about your turbos. In my head the turbos would be a bitch and read some stories where they died at like 100 000 miles. Is your car stock psi? |

It would be a job that I would definitely take my time. I have my entire intake system upgraded. FMIC, Bigger CAI, 1.75" Silicone Inlets & 2" Outlets Plus I have upgraded my entire exhaust. I don't have a tune. When I get new turbos, perhaps. I will get new coils & plugs from FCP as well as new turbo actuators at that time. (Lifetime Warranty) My injectors have a lifetime warranty. Tunes cut the service life of coils, injectors, turbos, & plugs in half. That would be the only way I'd get a tune if all the "laundry list items" were under lifetime warranty. One thing you absolutely, positively need to do from day one, once you get a 335is is get a catch can an Rob Beck PCV & Metal cap. I'd suggest the Mishimoto catch can. I'd also replace the crank case valve near the PCV valve as well. |
