From Riss Racing: What do we 128ers want to see on the market?

[1ntense_Rocket]

catback... + intake

[spam052]

i would like a 3stage intake kit.

[derekL]

bump! no replies for this means that no new parts from riss racing for our 128's guys!!

[1ntense_Rocket]

cmon guys i desperately need an exhaust!! full cat back and cold air intake to start!

I would like to see a high quality but lightweight and relatively inexpensive supercharger kit that could give say, an extra 40 - 50 horsepower. Many feel that we should just go to a 135i if we want to go fast, but there are good reasons to work with the 128: maybe I bought mine a month ago because it was what I could afford then, but got a job promotion and pay increase yesterday, but realize that trading up now wouldn't be practical. Or (as in my actual case) maybe I wanted to buy an in-stock vehicle and not wait for an order, but every 135 I could find was loaded with all kinds of weight-adding crap I don't want? Then there's the soon-to-be-growing used market to consider, those buyers will want to mod. What, should we just forget about hot-rodding and simply buy the top model? Does it mean you've only got one nut because you choose a 5.7 liter Challenger instead of the 6.1 Hemi? Anyway, it's too bad nearly all supercharger kits are striving for huge numbers and are as expensive as they are. Not sure if a kit could be produced to work within the capabilities of the stock injectors and other parts, but if I could spend $2500 and end up with 275-280 hp compared to the stock 230, along with a nice torque boost, it would be sweet and do-able and I wouldn't care if it were not as fast as a 135. While I'm at it, is there yet anyone reputable making an ECU or piggyback device that would give 20 or so plug-and-play ponies?

ECU 20-25 hp, inexpensive moderate-gain supercharger kit 40-50 hp/$2500

This is the best idea, iv been tryin to find the answer for months..
i already have a full exhaust with a decat and a K&N filter... still not enough for me.. ECU software is the next step for considerable gains.

i want to see body kits for the car. Anything decorative would be a good choice, especially the interior. I dont think anything to increase speed or sound is worth spending and upgrading. If it was then i would have gotten the 135i, which would probably cost the same amount for the hp and torque and i still get a warranty and the value of the car wont go down as much as aftermarket stuff placed in a car.

I reckon a solution/package/kit to get the same or better grunt as the 130i for the 125i would be a winner. I don't know what would be required, or the costs, but if you could improve the power to that level with a specifically designed kit, you'd sell quite a few.

[Fireflyer239]

How about 307 hp/246 tq with daily driveability and very reasonable cost? Here is their E46 stage 1 kit, cost is $4,400:

dude, i can't read that.. and the online translator doesn't work since it's not a text document.

Any chance someone can translate

I talked with those guys before I started my tuning plan.
They (indirectly, as they are smart guys to sell their know-how free of charge) opened my eyes in terms that 125i is virtually 130i with only software power downgrade for marketing reasons (thanks BMW !).
Also, that after 09/2008 BMW introduced new security program in ECU that makes such changes way more difficult (so several tuners like Dahler stopped marketing their chip tuning on newer cars).
Still, any 125i onwer can send their ECU box and after re-maping (at around 1800 cost) car delivers full 130i power and torque without any further mods.
I think it is worth, as I tried such modification (thus by other software guys who did it privately for me, as I expected to go to 'stage 2' tuning later).
It is interesting that tuned 125i/AT gear with shorter final drive ratio than 130i/AT in practice (although slightly heavier) showed some edge in acceleration.
With manual gearbox, IMO 130i is still a bit quicker than tuned 125i.
So, if you are happy with improvement like that DS Motors offer is effective way to reach it, although local software gurus should be able to modify 330i software in order to work equally in 125i (specially problems with security codes and here I can't help you more, as software manipulation is not my specialization).
The point of 'localization' lies in fact that dealer can 'upgrade' software in ECU and practically erase 'tuning'. Local guys can always load it again for you.
As I didn't wish to go with camshaft replacement and other 'real tuning' measures that bring power to 305-310 HP without turbo, I opted for upgrade on airflow (with Injen intake and decat downpipes + straight tube Bastuck exhaust system). This might go against your local ecology norms, so I can't recommend it to all, but in my case, loudness and emmissions are withinn soft standards of local regulations, so no problem.
This step opens new heights for engine, but requires further ECU tuning (many parameters are changed, so to get optimal results, stock 130i software is slightly limited). Intake+complete exhaust without cats+ECU optimization change character of engine (much lighter revs in 5000-7000 rpm range) and subjective feel is very sportive. I don't have final proofs of dyno, but car pushes forward much more intenselly that 130i, very near to stock 135i range (around 5,5 s 0-100 km/h with AT).
Noone, so far offers such 'stage2' tuning commercially and I think it should be target for tuners with expected budget 3500-4000 $.
For countries in which price difference between 125i and 135i is much more than in US, as well as, annual tax double or triple, such tuning has lot of sense. If not, buying 135i would be no-brainer.

Exactly!!! I talked with this company as well. I would be cooking at 289HP with an intake and exhaust. What I'm curious about is what I will be looking at as far as power when I add a supercharger to my 128. Will I still have that 59HP gain on the stock 128? Its frustrating because this car has been out for quite some time and there are !@#$ for parts. This engine has been out even longer. Of course I wanted a 135 but i don't. From what I've been reading it seems to me that the n52 is better than the n54.

[Greenkirby21]

hehe lets make this very simple : )!!

more power for less cost ratio. Whether it be a supercharger, ecu chip, etc!

Great minds think alike. May I add one thing? Less cost ratio does not mean cheap parts...i still have an expensive car

I know the SC on another bimmer for about $5k added 125HP so if you are adding 75 make it $2500 I'll take either or parts...whichever somes out first =P

[jaf89f]

Just like most people, I would just love to see more parts in general. Tuning for the 135i is a breeze partly because of their turbos. I would love to see some sort of kit to make the 128i become a 130i or even a smaller supercharger that increases power by about 40-50hp.

You are talking about this Riss Racing? Which is now defunct.

was just about to say.

[B_2_B_P]

Really was talking in general but ty for the word. Doesn't change what I want =P

[Sdracing]

I would like to see a full cat-back titanium exhaust... I'm not sure what the stock exhaust weighs but you could probably knock 25+ pounds off vehicle weight with Ti exhaust.
