Hey Guys,

Im fairly new to these forums and I picked up my 335i a couple of months ago. I am slowly being sucked into the modding scene and I've trying to read threads and trying to understand what certains mods do, their results,what is available and the different companies that make them.

I am looking for a FAQ, or just a general guide to follow for newbies like me, in different intakes, exhausts, chips, and other modifications available to us.

In terms of chips, im all confused between a JB2, JB3, Procede V1, V3 Procede Maps, whatever it is....

A simple list, descriping what it is, what it does, pros/cons of all mods listed for the 335i would be sickness.

Thanks for understanding, im just starting to get some knowledge about mods for our cars.

I think the best way to start would be a Tune (either the JB3 or Procede) and a Dual Cone Intake.

These are probably the best mods to begin with as they will transform the car. If you so choose you can continue modding with exhaust, intercooler, down pipes, etc, but all those yield marginal results as compared to a Tune..

I won't get into which Tune is best for you, but do some research, and I would focus on the JB3 and the Procede V3-RevII as those are arguably the best most popular tunes right now.

Good luck

Mike

There's a sticky that lists all (or a lot) of the goodies you can put on your 335i. http://www.e90post.com/forums/showthread.php?t=90706

It's not 100% or up-to-date, but it's pretty comprehensive. Have fun and be safe!

Definitely check out this sticky since there is lot out there.

Then you have to decide what tune you want to try.

If you are completely hands off you can get a flash from Dinan ~50whp gain
SSTT is a simple plug in no tools necessary ~35whp gain but very noticeable because of the torque.
If you can use a screwdriver you can get ~ 100whp gain with a piggy back tune like Procede V3 PNP, and from what I have observed on this forum this seems to be the hands down winner in terms of driving experience and throttle response, I don't have this tune yet, but maybe some day....

If you want to be safe do :

BMS or Vishnu dual cone intake (makes it easier for turbos to suck air, so they spin slower for same results)
[there are tons of fancier options for intake too]

Forge or Riss Racing Diverter Valves (helps keep you from getting a boost leak, and from damaging your turbos)

FMIC (keeps intake air cooler, making you need less boost for the same power, saving wear and tear on your turbos)


For longevity do :

catch can (keeps you from sucking burnt oil into your intake)

oil cooler (keeps your engine temperatures down, and the turbos are water+oil cooled, so they will thank you too.)


For performance, start with :

JB3 or Procede piggy back ECU (runs your turbos and fuel system harder do you get more power)




Then do :

Downpipes (quicker turbo spool, less back pressure)

Full exhaust (quicker turbo spool, less back pressure)

Do the dual cone intakes generate extra noise?

Not much, you can hear the turbos spool a little better, but it's nothing overbearing or annoying. I don't see it getting old.

[Sniz]

look into the ESS flash too.

[zeeman335]

Awesome replies, keep it coming!

A little off topic, but my only concern is the warranty,all this is tempting but what's the point IF it voids ur warranty with BMW. Isn't there some sort of law/act stating that if they can determine that it was the modification that caused the problem they cannot void the warranty?? What IF BMW saw a dual cone air intake and told me that they are NOT going to touch my car because of that?

[poloace]

what kind of gains do you see with the dual cone intake?

Whats the difference between the Dinan and SSTT,or the ESS??? Are they competitors to the JB3 and v3? just different companies that make the same thing with different HP/TQ gains?

Depending if you're stock or tuned, and if tuned which tune/which map

5-20hp/tq

So 5 if stock and if tuned (i.e. V3, JB3,etc...) then we are looking at 20hp gain?

Basically

Stock 5-10
Tuned 10-20

Its hard to get an accurate number, as dynoing does not necessarily reflect the true gains from an intake, which is why I recommend getting a simple cost effective dual cone intake.

I actually talked with my service advisor about this last week. Mods such as intake, exhaust, etc. USUALLY only void the part that was modified. In this case, stock airbox and stock exhaust system. It is kind of a gray area because it can also void the warranty of other parts if they can prove that the mod caused another problem. He gave me an example of someone who came in a few weeks ago with a CEL and he had just put on an aftermarket intake. Turns out that the intake was what caused the CEL. (not sure what brand). The SA said he ended up getting updated to 32.1 and it caused the CEL to go out, so he didn't get charged for the service. If the update had not fixed the problem, he would have been charged.

My priorities:

1) tires. Get extreme performance non-rfts. Sell or save the OEMs.
2) wheels. Get lightweight forged rims. Sell or save the OEMs. Use to mount snows.
3) steering wheel, shift knob -- I really like the M-sport stuff. Great value, something you notice every drive
4) tunes -- Procede, ESS flash, ... Big issue here with warranty though.
5) shocks & springs -- BMW Performance good deal, coilovers nice.
6) intake
7) exhaust
8) LSD -- expensive mod, Quaife mandatory mod in rainy places like England.
9) Further suspension mods -- M3 control arms, sway bars, ...
10) weight reduction (battery etc.)

You can easily spend $10 - 15k. and little or none of it will increase resale. Very expensive hobby.

The 335 is a fantastic car out of the box. Fully modded it is a beast with near-exotic performance.

[zeeman335]

Quick question:

So the JB3 and V2 are comparably in terms of hp/tq gains? From what I did my research on,the JB3 is like $585 and V2 Procede is more than $1000

Why would someone want to get the SSTT? That seems like a quick easy mod,not too expensive, and adds good amount of hp/tq.

The best thing for you to do is arrange to meet up with some people and see for yourself which better suits you. The deatils of a tune written on paper only tell half the story. The other half is in the drive.

Since I'm also a 335i noob (but have already got the PROcede & SSK), I have a question about the intake mod.

Doesn't the dual cone intake have a design flaw since it is sucking in hot air from the engine compartment instead of CAI-style from the front of the car like the OEM intake?

No, that is what the intercooler is for. There have been several discussions about this. Search the forums for a more detailed explanation. There have been a few tests done about this that proves it.

A simple list, descriping what it is, what it does, pros/cons of all mods listed for the 335i would be sickness.

Thanks for understanding, im just starting to get some knowledge about mods for our cars.

The sickness:

Forget PROcede v1,v2 or jb1 or jb2. Older gen tunes. We've all moved on since then considerably.

PROcede v3 PnP
Pros: Best drivability, best engine response, off-boost gas mileage/torque improvements, great power, user adjustability, remote control mapswitch, speed-delimiter, active timing control, data-logging, free software update-ability, new features added/unlocked regularly.
Cons: $945 which is ~$360 more than competition

JB3 PnP
Pros: Inexpensive ($585), great power, map switching between 7 maps with gas pedal.
Cons: New maps involve replacing a physical chip which costs a little $ and involves shipping, questionable timing control, limited upgrade path without entire system replacement.

The extra features (datalogging, free updates, speed delimiter, etc,.) of the PROcede may or may not be important to you. So that means the only critical difference is how both tunes drive. And for that, you will need to test drive them both and see if the benefits of the PROcede are worth the extra $360. It's also a possibility that you may even prefer the more on/off nature (relatively speaking) of the JB3.

Disclaimer: I am the developer of the PROcede. So one could easily argue that I'm a bit biased. On the other hand, one could argue that I've done more in-depth testing than anyone else on this forum
