Just bhp/torque numbers, S$2500 can get you Procede V2.02. S$1400 thereabout can get you the Juice Box..........

See the figures for yourself......

JUICE BOX 335i PERFORMANCE TUNER

[benz61]

I am currently in Nagoya and I happened to be brought to the BMW showroom to see and test drive the all new 120i cabrio ,135i and the M3 sedan. Like what I told Andrea before I came up a M3 is always a M3 the rigidity of the car and the handling of the M3 is just different from our 335i. I now love my 335i even more ever since Andre did some tuning for me. But I am afraid that my 335 will be very fast for sales as I think I will proceed to purchase the new M3 sedan. I always believe that the sedan handles better than the coupe is really true even for the M3.
For those who wants to buy a nice cabrio for yourself or wife the 120i is the car to get it is so beautiful in the flesh quality of the car is damn good and the of course the 135i I think in term of fun this car is really fun , buy it you will not regret it. This afternoon test drive prove to be very expensive as I am quite sure the M3 sedan and the 120i cabrio will be in my garage soon

LOL, if you want to sell your 335i, please give me a shout hor. Although I am sure you will not be short of interested buyers in light of the waiting period for a new 335i.

Kenn, not really so easy and cheap lar. From the US BMW forums, the `simple' piggyback system places extra stress on the engine and turbos beyond engineering design parameters, which requires you to add similarly uprated devices like an intercooler to cool down the charge and probably uprated diverter valves. Seems to be necessary mods for piggybacked cars, from accounts from Arizona and Singapore, and on the track, even more so.

Failure to do so has resulted in ECU retard, diverter valve failures requiring turbo replacement, etc. And who knows what it's doing to the engine.

Modding a 335 seems not to be as easy as modding an Evo.

the engine is pretty tough, so both for NA and FI engines are (mid-term) fine if you don't go crazy. It's the turbos which give trouble. Take a survey of the 335 owners in the bimmer boards in USA and see their turbo-related issues, including worn out components, plastic diverter valve failures, turbo failures.

You should know from Omar by now we dun discussed most 335 mods online anymore. Yes, not as straight forward. The heating issue was inherent in the 335, even stock is running 120 after a spirited drive. Hence the OC, not the IC, is a primary mod.

As for the rest, FMIC and DV, it is all in the pipeline. Many of us have already installed the DVs. Cheap mod. As with most of the mods we have come across so far. High yielding as well. Compare that to what those guys in the US tried to do.... 3-litre engine block swap, SCed and so on...... I still think it is a relatively easier-to-mod car.

Most of us have tried both the Procede V2 and the JBX piggyback systems - BOTH !!! And only we know whether it works or otherwise as per your depiction.

Right. Because nobody discusses the issues of 335 modding online anymore, it's fair that you mention now that, 335 modding is not as straightforward as just putting the ECU modifier online.

No I didn't talk to Omar about 335 mod online discussion.

The margin of moddability of the 335i is tremendously great. Increase boost by almost twice in terms of PSI. And the feeling is night and day difference. Of course running higher boost will definitely imply a higher rate of wear and tear. No doubt about that. That is why it is imperative that mods like FMIC, DV and DP are REQUIRED. They allow you to run consistent high boost. I have no doubts that the N54 engine is a strong motor. But i feel that the other parts like the FMIC, DV and DP are weak links in keeping the sustainability of the 335i.

In terms of power, i got a chance to drive a stock 335 again to show my friend who has just bought one. I realise with the stock power, the 335 handles like a charm. Not to say a modded one handles worse but its much more of a challenge to drive due to the rear end kicking out much quicker and faster. For that reason, the 335 is seriously lacking in one thing. An LSD. For our kind of power, it is pathetic that the car dont come with the M3 differential. Stock power lets you get away fine. Modded 335, you most definitely need an LSD unless you are a 1/4 mile kinda guy.

I think i have been running my car for 7 months now. I nail the car really hard to expose whatever weaknesses i could. I just went into service yesterday and they did a full check up. Rear disc pads had to be changed. The SA was puzzled how come it finished so fast. Simple. The rears cannot keep up with the braking power from the front. It is being overly stressed to the point I can feel much bias. No matter. Alcons got the rear kits out. Am definitely gonna get it. So i can say that the N54, being a BMW's first turbo engine since 2002, is relatively good. In e90post, certain cars are affected by fluttering noise and got their cams and wastegates replaced undfer warranty. Those are just a few cars. I have not since anything major, like someone blowing up the engine, or having a busted tranny. The car is a well engineered car but certain parts HAVE to be changed to run the kind of mods some of us are doing. It simply will put more stress on the motor and drive train if you run everything stock except the engine. As far as modding the 335 goes, its far simpler than modding an evo. Which car allows you to boost 100hp over stock and still run the same fuel injectors, same fuel rail system, same spark plugs, etc? Not many cars in todays generation where manufacturers go all out to reduce their costs on cheaper parts to run the car at stock levels. Think abt it.

As far as i know, evos that mod HAVE to change all of these to get the power they require. For that reason, I think the 335 is much easier to mod though ineveitably, the evo and rexes will undoubtly give you more power than the 335 as they have more options available to them. For most of us that have the 335 as the first turbo car, most of the stuff have already been spoonfed for us. I cant ask for anything else. The goal of modded 335s should be sustainaility and keeping the engine cool. With this 2 elements, I believe that the car will serve you well. Well to make us more consoled on the reliability of our turbos, rumours have it that we are running the EXACT same turboes as the bugatti veyron. Of course its just 2 of them. But for the same 2 to go into the veyron is a testament of the parts that is going into our car. Its sad BMW sacrificed things like DV and FMIC without having more room for running the boost levels we are seeing.

My 2 cents....

You watch me. If I a get a 335i, I will keep to the "stock is best" motto (cosmetic mods excluded). Otherwise, I buy you a big ice lemon tea from MacDonalds.

Ken is a vendor now. You'd have an even harder time to resist the poison compared to before....
