On a slight segway- is there a recommended Indy Shop in NoVA region for mod work/ and otherwise. I've checked out a couple out where I live, but they dont inspire much confidence. And the Stealership here is at completely another level (I cant even trust them with an oil change)

It depends on your inspection.. OBD-readings can be manipulated so that the emissions look fine. Emission testing by a sniffer depends on the limits which you have to pass. For example in my country there is a emission limit which is the same for EVERY car, as long as I have a cat installed I will probably pass that emission test. Most authorities/countries probably check the emission-reading against the specific emission values of the car/engine or a certain class of emission, in this worst case you are probably f**ked up and your only option is to try out high quality 200-cell cats which should have the same filtering properties of a OEM 400-cell or changing the downpipe before every inspection.

Passing the emission test is one thing, the other problem is that the inspector will probably see that you have installed an aftermarket downpipe because it is to shiny or whatever.. if he is smart he will know that between two O2-sensors there need to be a catalytic-converter. It all depends on the inspector.. I don't know how strict they are at your place.
I do always pass the emission test by a sniffer, but I mostly fail at the inspectors because they know how a downpipe should look like and that's why I bought a used set of OEM downpipes and replaced the cat with a straight pipe, looks like OEM

I don't know why you are concerned about warranty when installing a LSD. A tune, downpipes etc will void you warranty to. You will probably remove all mods before doing a request for warranty. As long you don't have problems with your diff, no one will see that you have installed a LSD! No one will open your diff to check if you warranty is still valid when your doing an injector warranty request for example.
By the way.. did you ever did an oil change by yourself or probably an indie-shop? This can be a reason to reject your warranty request for different things.. happened to me..

The question about what to do on the handling first: If you have a M suspension it actually is fine for few trackdays per year. The missing camber is actually the main problem and camber can be added with the M3 wishbone at a low budget. M3 wishbones with a proper alignment will give a noticeable difference while cornering. A proper suspension will cost you the same as a LSD.

Therefore my opinion: LSD with M3 wishbone > suspension (if m-sport suspension)

By the way: when doing the LSD install, consider to change the rear sway bar to M3, because it can be done in few minutes when they are dropping the exhaust etc for the LSD install.

Thought I'd post an update and get some more feedback for people who contributed with their comments/suggestion. This is in a way me thanking all those who contributed, and a vague method of keeping a journal

In the last few months I actually got more done on my car than I initially planned on, but if I were to do it again, I'd probably do the same

First I got myself tune (JB4), and it was an absolute no-brainier! Cant think of a better bang for buck. And since I was getting those I also got myself a set of DCI's. Now these probably arent doing much, but I like the sound they make.

My third mod was getting an oil cooler for my non-oil cooled 335. I wasnt planning on getting one anytime soon, and I could certainly curb my need to step on the throttle when the temps started rising. But I found a deal just too good to pass up. One of the forum members was passing up on an OEM oil cooler, and I got it. As it turns out it worked pretty well. The temps now hold much better, and I know I can now keep playing just that bit longer

The fourth on the list ended up being an OEM Short Shift Kit. Now this is something I just had to get. I know the BMW shifter is an acquired taste, but the oddly long throws were sucking out the pleasure of rowing through gears when you were really up it. I just could not tolerate how each throw was just that tad longer. And I suspect BMW knew exactly how much over optimum those throws were, because the Short Shift Kit is just Perfect! Its still notchy in a BMW way, but now its precise and crisp. Besides the JB4 this is probably the best mod yet.

The fifth- well not really mods per say. Got myself some LED halo replacements. Which are nice, but I liked the OEM too. thought they looked distinctive, especially now that everyone has white LEDs. I probably wouldn't have bought these if the OEM didn't go out.

I suppose I am done with mods for a bit, but sure would be nice to get some more insight from people. I defenitely plan on ditching my RFTs, but you know what I dont completely hate them, probably because they do make getting the tail to come around quite easy, but I could do w/o that dab of understeer. I think I'll be going handling over power (a DP is never too far away). But to be honest I need to be a much better driver before I make the car any better. I dont think I am good enough yet to drive the stock car to 10/10ths, and though there are aspects I'd like to improve, I dont want to make the gap between my skills and the cars skills to big before I master it.

Thank you all for your suggestions, please keep them coming, you inputs are genuinely appreciated!

cobb v3 first!

[M.Power]

I just got a 335i too, and am debating the JB4. Going to push it off for now because of the reliability issues honestly.

[cky751]

Before modding your engine make sure all the maintenance is done. Spark plugs should be replaced before tuning. Make sure you go with NGK plugs.

Absolutely! The first thing I did on the car, was replace the Sparkplugs and Battery (still had the old dog). recently had all my fluids flushed as well. Didn't bother with Walnut-blast, as it had one done at 70K

Reliability? sorry to hear that. what up with yours? I've always maintained these cars, or any car for that matter are as reliable as their owners. As long as the previous owner took good care of the car you needn't worry

[Fundguy1]

Juicebox 4 v5, non run flat tires on 19" wheels, them FBO. That's 7" FMIC, charge pipe, catless downpipes, intake. Mot crazy price but will get you vast improvements in power and ride quality over stock.

Never heard anyone saying a Juicebox made anything unreliable. Zero. Same with Cobb. Find an example on here maybe. I can't. I've run mine for over 200,000 miles. I've had repairs but same mileage and parts as bone stock cars. Mainly High Pressure fuel pumps, which have since been redesigned, and waste gates, also redesigned.

Thanks for that comment, you're kind of convincing me to do it.

Your welcome. Dinan offers the same thing essentially and warranties it but theirs is a little less sophisticated, costs more, and isn't quite as effective. Add an oil cooler if you're going to do any track days too. 2007 didn't have them. 2008 on did from the factory.

[Nitrousbird]

It's not performance enhancing, but you should get an oil catch can as well. Charge pipe is a good idea...again, not going to help much performance wise, but if it breaks that will suck (I'm typing that and am still rocking the stocker...for now).

[B.M.W.]

Here's my list. Nothing to crazy, I just wanted a sleeper & family friendly car so e90 335i Sport. I'm only on 4 as of now, no real need to rush the build as where I'm at is great! 400+whp easily & 36mpg on the highway!
Zero: Maintenance Spark plugs, coils, oil, walnut blast (if carbon is built up bad) & trans fluid (just to be safe)

First: Basics Oil cooler & Catch can if you don't already have them, it'll help once later down the road. "Golf Tee" Mod, Angel eyes fix, window tint & USB retrofit.

Second: Tires. Michelin Super Sports are great, but keep the normal tires on so you can wear them out a bit before you swap

Third: Jb4 G5-Map 1 for awhile to get use to the interface, then map 5.
You'll need to do 3 Wide open throttle pulls in 3rd each time you set your JB4 to map 5. It adjusts for weather, altitude & fuel so you may need to redo the 3 WoTs to keep it synced with the weather.

Fourth: Coilovers & Downpipes. This gives you some handling & power as well.

Fifth: LSD & M3 Sway bar. Helps put the power down & helps the car become a killer.

Sixth: Upgraded brakes, turbo inlets & red stickers for 500+HP

Se7enth: Upgraded Twin turbos or Single Turbos.

I must be on eighth.

I didn't plan on modding it this much as it sits. I do however want those cool Recaros they use in the F-Type though

[335xMD]

I bought a Route66 extended warranty when I bought my 335xi @ 87k miles. Unfortunately this has limited what I've done/plan to do. I would like to do DPs & FMIC, but I feel those are just past the threshold of what I'm comfortable with doing given the warranty. Most of the stuff below is readily reversible or won't draw attention (new CP, stage 2 LPFP), and I don't think I'll get much flack for an OCC given that it's essentially a preventative/protective measure. That said, I've been made aware of an apparently mod-friendly shop near me, so if things go well I'll probably add DP/FMIC/meth to what's below

Initial Maintenance:
Spark plugs
Ignition coils
Walnut blast (immediately following 2 tanks with Techron Concentrate Plus)
Oil change
Transmission fluid change
New vacuum tubing

Upgrades/Mods:
BMS DCI
Upgraded RB PCV valve (holding off on OCC for now)
JB4 ISO
BMS modified clutch delay valve

Future: (in no particular order, not sure yet...)
Fuel-It! Stage 2 LPFP
Charge pipe (black w/OEM diverter valve setup to look stock)
Oil cooler retrofit
OCC
Flash

(exterior/interior aesthetic mods not included... things I've done/want to do are too numerous lol)

LOL..you are like on 11th. Ive read about your mods and what you've done with your car. I must say I am fan! I too intend to build this car along as I go. Hopefully mine will last me till 200K (its just at 90K at the moment). I probably will never upgrade the turbos, unless ofcourse they crap out on me.
I think the chassis of the E92 is lovely, especially at the limit; not that I am some pro drive (guess that what makes it better :P)

So where have you reached with your build? would love to know. it is quite inspirational.

I'm in the same boat. Have warranty on it so most of the stuff I've done is keeping that in mind (except the JB4 )

Do you have manual. Get the Short Shift Kit. I cannot tell you how much of a difference it makes.

Hey man, I just saw this comment. My car was honestly very well maintained and I'm surprised at how clean the last owner kept it. All I need as of now is a new wheel bearing which I already ordered. Just want to get maintenance out of the way before modding.

[ritzzzzzwik]

Alright folks, to keep this journal going..

I sort of went away from my power mods after a pot-hole did more damage than usual, earlier this year- bent two wheels, caused a the weld to come off slightly off the rear subframe. This made me want to address the suspension before I added any power

So I not have the following suspension mods-

-M3 Front control arms (upper and lower)
-Koni FSD all around
-New wheels and tires (dont really like my current ones, Goodyear & ASA, will get PSS & APEX next summer)
-replaced rear sub-frame
-Whiteline rear subframe bushing

Now that I'm done with the suspension I'll get back to the power

I do have a quick Q- How much power do you guys see on a FBO N54 on 93Octane, without using meth or E85?

I've check through the sticky, but thats a huge information overload! Everyone does something a little diff, just looking for a simple 2-3 word answer (hopefully w/ a number)

[BeastMode335i]

Before you start chasing higher HP numbers, my vote goes to starting with general maintenance first.. Check your Plugs, Coils, Injectors, Intake Valves, and for any leaks because once you add on HP you're going to find your engines weak points right away.. Just my .02

[ritzzzzzwik]

very valid point, but I believe I've taken care of those. Plugs done 12K ago, replaced VANOS solenoid 5k ago, walnut blasting done at 70k (at 102k now, will do another this year), retrofitted oil cooler, all fluids done around 10K.

I have DCI and JB4, seems to be pulling, don't know how else to test the car, other than loadingbit up and going WOT from time to time I want to go FBO, because if I am upgrading parts, might as well get some power, mind you NOT the turbos (no smoking or whining or rattling yet). So I wanted to get an idea what number people get to w/o getting e85 or meth these days. Looks like people get significantly more for the same mods than they did say 4 years ago.
