Hey everone,

I just purchased a 2002 BMW 330Ci 5-speed. I definetly need to get some more HP out of it. First thing that came to mind was CAI. Would anyone know of a BMW CAI out there that makes the best performance impact? I was looking at Dinan... but get real for $500+tax+shipping! There has to be a CAI out there that does just as good a job for cheaper. SUGGESTIONS WELCOME!

I also looked at the Dinan CPU chip which adds 250 onto your rev limiter. Anyone out there know of any CPU chips that actually do a better job at regulating fuel and increasing HP?

Let me know your experiences if you have any with CAI, Chips, or exhaust.

Much Appreciated!
-JK

Thanks EuroBeem. The clip can be found on our site {HERE}.

Keep in mind it is aggressive. I LOVE it, but it's not quiet. Many BMW owners may not wish for such. IF you want something a little more subdued, you might go with Remus.

BTW, Dinan products are first rate, but they aren't cheap. Gotta pay to play boys...

Also remember that if you car is still under warranty my understanding is that anything non-Dinan may void it. Of course it depends on what non-Dinan mod you use and how it affected or not affected the issue to be covered under warranty.

BTW - the Borla exhaust does sound sweet!

I've heard great things about the turner motorsports mods, specifically the CAI and shark injector (chip reprogrammer). According to guys I've talked to: 1) software reprogramming undetectable by your dealer (and you can easily flash it back to stock settings) and 2) modifications only void your warranty if the manufacturer can prove it was specifically attributable to the modification.

Good luck!

In response to the last post. I have a '99 328i that I just bought and found out it is a Certified Preowned. Clock say 72,000 miles and its good until 100,000. Therefore I was pleasantly surprised since the lot I bought it from sold the car to me as "as is---no warranty." Therefore, I do NOT want to blow this warranty. I would like to shark this car with the Conforti reprogrammer. So what you are saying is that this could be added and NOT blow the warranty? That would be great.

ECIS in my opnion makes the most affordable intake for BMWs.

but the "BEST" would be GruppeM.

GruppeM + Shark or Technik software would be your best combo.

I got this error message "Sorry, an error occurred. If you are unsure on how to use a feature" when I clicked your link. If you say it is loud then I believe you, Remus may be more up my alley, i don't want a muscle car sound, I just gave that up! Something a bit more refined yet aggressive.

For you, niether. I would only recommend a supersprint exhaust for an e36 328is. They're the only company that produces a 328 specific exhaust. When it comes to the E36, all other companies produced an M3 exhaust, which also happened to fit all other e36 models. However, the piping is too large for standard 3 series, so you'll experience a loss of torque.

you can see pics of it on my old car here:
http://www.cardomain.com/id/iniquityx

damn do I miss that car....

as for e46's..

if you like dinan style, then get a benfer.

www.benferperformance.com

if you're afraid of sucking up water, then get either the gruppem or get the conforti if you're not willing to shell out $500+ on an intake, depending on where you get it..

www.eurosporthighperformance.com (conforti)
www.rennsport.com (gruppem)

with that in mind.. conforti software was designed with conforti intakes, and technik software was designed with the gruppem.. so ideally you'd want to match one with the other.. however, mixing software and intake isn't bad..

Active Autoworkes makes very good software.. but it is pricey and your car will be undrivable for a few days b/c u need to send them your ecu. conforti offers convenience, and right now technik software is not being sent out because people don't return the cables.. only way is to go to rennsport directly.. However, i believe Rennsport is licensing the shark injector casing from eurosport to use for their own technik software.. they haven't confirmed, but they've hinted.. plus, with the recent installation of their new dyno, you can expect some announcements in the near future..

with respect to exhausts.. it's all relative, they'll all produce similar peak powers. they mostly differ in tq and power curves. I felt getting a full catback was pointless, as the stock e46 system is already nearly straight through.. it would only yield like 1-2 horsies max.. not worth the extra $300-$500 in my opinion.. if you must.. full catbacks provided by Borla, UUC, and Supersprint.. i would recommend Supersprint then Borla...then.. uhh.. that's it.. :nana ..

rogue produces a "halfback" exhaust which replaces one res with straight piping.. i would have gotten this, but i think the tips are ugly.. the dms exhaust is typically known as a middle of the road loudness.. it's definitely got presence..

supersprint, remus, and active autoworkes, and eisemann (certain versions) are known as the quiet end... the eisenmann race w/soundpipes is loud however..

B&B triflo is extremely loud, but also very aggressive. It's as close to a V8 as your car can sound..

http://www.bbtriflo.com for sound clips
http://www.bavauto.com (they sell it cheaper)

I finalized between an AA, SS, and Eis. Race. However, I had an SS on my old car, so I wanted something a bit louder.. (I really wanted the Rogue, but those tips.. i still couldn't get past the fact that they looks just like the new accord coupe's..) ... sooo.. SS exhaust out... i wanted the Eis. Race w/soundpipes.. however..1-2 month wait while they build it and ship it.. horrible weld jobs, and too many stories of poor fitmen... i ended up with the AA and I like it a lot.

it maintains a euro sound/hum...down low it's deep and somewhat burbly, especially when u let off the gas.. at higher revs cruising it sounds ferarri-ish.. a higher pitched humm... and WOT the thing screeeeeeeems... with windows down, sometimes it hurts my ears...... BUT. regular cruising is unnoticeable.. barely louder than stock.. windows up or down..

http://www.activeautowerke.com/main.cfm
http://www.turnermotorsports.com (they carry many exhausts, though they aren't the cheapest.. only Borla supplier)
http://www.rennsport.com (they also carry numerous exhausts, softwares, etc.. etcand are more often than not, the cheapest place to get any bmw part.. mostly e46 tuning)
http://www.rogueengineering.com
http://www.m3motorwerks.com/index.php

personally, i've only purchased from the bottom three listed above..

also.. seems like you're seeking power.. i would highly consider a power pulley kit.. I recommend the Rogue pulleys..

How about getting Remus for $330?
from http://www.autoaccessorystore.com
It is not custom tailored for 330 but any muffler shop will install it
for you for about $40.
I just got mine for 2001 530i
