Im sure there will be a tuner near you. Just ask simple questions. 1. Do they have dyno? 2.Ask them if they log timing retards and fuel trims. 3. Can they do adjustments based on that.

Happy to help :)

Glad it was helpful!

Thank you lots Alexandre!

They get to the identical power level.

@@EuroSurgeonNz Thank you for the reply. Seems like the 320i might be a good way to go.

Does the downpipe you noted change the volume or pitch of the exhaust? Thanks.

Makes it marginally deeper, but not a lot.

Hey. This one got our own version. Modified stock pipe. Car needed to pass visual inspection, so everything looks bone stock.

the n20 in F2x chasiss is all the same story. B48 on the other hand is a bit beefier set up which could be pushed a bit harder.

Personally just wouldn't recommend pushing the n20 past 300hp. Catless, Cooler, Intake - Should be fun enough. Anything past that - Start with somehting that is made for 400+HP

@@EuroSurgeonNz 3.0l BMW should be nice, but its the future. Now will do my best with F31X changing it look to like F81X. Thx

Generally speaking all pops and bangs are harmful. You are throwing unburned fuel at hot exhaust. Then detonate it right next to turbo/Wastegate/o2 sensors. Generally avoid like plague unless customer signed a waiver.

Following as well! I'm getting my F30 330e this week! I'm also curious whether the tuning can be done the same way as the 320i does.

oh nice, your in NZ? i been looking at 335i active hybrid at the same time as well, looks promising

Nah I'm from Malaysia, our specs from 2017 and above doesn't have 330i anymore, the top spec has been replaced by the 330e so I'm getting that one.

Hey Tovey. 330E with B48 is a slightly beefier version of b48. The end result is solid mid 300hp at the engine with close to zero turbo lag. The closer comparison betweent he two would be older N55 335i and AH3. But yes, with similar mods as in this video 330E gets around 80hp extra and 120-140nm of torque bump. Would love to do the video on one.

Also, swing by for a coffee when you get a chance. Here all week monday - friday.

I second this

Since when did the F30 320i ever come with a B48? The engine cover is a clear indicator, but some parts will quite literally have engravings saying “N20” on them.

Yup, few comments above you the part number differences :)

Absolutely

To separate it from 328i, they literally brought down the power request. From throttle closure, to lower boost, fueling, torque limitation etc. Merc were the first ones to do it on C63 W204. Got a separate video on that.

@@EuroSurgeonNz cheers mate 👍

So n20 285hp on tune only? Good luck. Also, proof or GTFO.

@@EuroSurgeonNz Bootmod3 promises 100hp but i think like 280 is achievable but only with a DP and Intake right?

I have CTS intake vsrf down pipe and I use 93 gas dose it make difference

And I’m getting AWE muffler soon

Morning. Without datalogging is like asking a crystal ball. But lets try. Subject to to your ignition system being alive (aka coils/plugs), HP reading is top RPM, meaning you are not flowing enough up top. So Blocked cat/ Throttle closure/ turbo not very alive. Again, all guesswork without having car on rollers with logger.

@@EuroSurgeonNz i când send a log, all you mention are New! Posibile because of intercooler? I mounted a oem intercooler from 335d, this can be the cause? How much boost i can run în stage 1? Thank you very much.

Поршня разные и от этого степень зжатия 328ю можно больше надуть

you will have a different engine, b48 instead of n20, and start with the tune before you do the downpipe:) in saying that, b48 tends to melt cats a lot so tune + downpipe is ideal.

@@EuroSurgeonNz thank you so much! How much hp do you think I’ll be able to make out of my B48?

talk to whoever will be tuning it for you. There is no pre-set number.

Yes they do. They share 99% of components.

stage 1s and stage 2s are very safe. if u go over stage 2 and you start raising the pressure you gotta make sure your engine is built and serviced properly.

Hey. It will all depend on a tune/Condition of the car. On this particular car its 233 WHP, meaning this is closed to 280-290 BHP at the engine.

It’s stock besides the downpipe he said it in the video 😂

If i remember correctly it depends if you have GPF or not, but the non GPF cars are reasonably happy at 300 ish. Sorry pass on BSR, looks like another "bluechip" hand held flasher gimmick thing. Would suggest taking it to someone with set of rollers, as this is literally the only way to datalog the car properly and to see what the output is.

Unless you want to do multiple 4th gear pulls with traction off from 1500rmp to redline :)

There is no rule of thumb on what power/car has issues. Everything can be pushed to the limit safely, if you have matching hardware. Just find a reputable tuner in your area that has dyno and can provide full logging of the car

@@EuroSurgeonNz GPF would make more exhaust counterpressure as so does the catalyzer, I have one 120i b48 and I imagine it has those parts so I would expect 260-270 hp from a safe calibration😛

Yeah BSR claim 278hp on the B48B20A, wonder why most other tuners come even remotely close to those numbers, they claim 310hp or something on the B48B20B which may be more likely but probably not haha. 11:1 vs 10.2 compression ration unless I am totally off, to me that is a big deal and no personally not all B48 are the same. I went for the 330i just cause of that, but 100% new to BMW so take anything that comes out of my mouth with a full lorry of salt. Check with the experts instead.

And remember the 320i is a bit lightweight

8,890 mi away from NJ. Auckland, New Zealand.

@@EuroSurgeonNz ahah

Find a local to you tuner, see what they come up with. A bit pointless doing it over youtube:)

320i n20 with a tune has more BHP than 328i stock does.

Hey. On which Dyno? Inertia dynojet? What boost/fuel.

@@EuroSurgeonNz i dont know. it says Advanced Dyno Station: Dynostar does that help? 276.1hp @5250rpm / 465nm @3792rpm

@@Bonbloc yup, I know these. Quite “optimistic” reading dyno. However, numbers don’t matter, unless you have what’s called baseline”. What did your car run stock? Was the stock number same as I have, or was it like 180-200hp? Because the dyno number by itself is pretty much a waste of time :)

It is a stage 1.5 Hahah, i think they changed the downpipe if I’m not mistaking

Hey team. Yup this is a tiny bit more than stage 1. From this point really need an intercooler, intake and Charge pipe that doesn't want to Chernobyl itself :)

@@EuroSurgeonNz so to do this you only need to change the downpipe?

Yup, look up n20. Pretty cool set up, later replaced with b48

yes it will haul arse.

@@EuroSurgeonNz really ? I drived a e92 335i with the n55 and was blown away by the acceleration of it, if it can replicate the same with stage 2 on 428i will definitely do it

Hey. Crank is actually the same. Here are the identical part numbers. Cylinder head - PN 11127624778 Connecting rods - PN 11247624616 Crankshaft - PN 11212212762 Intake manifold - PN 11617588126 Air box - PN 13717597589 Air filter - PN 13718507320 Intercooler - PN 17517618809 Radiator - PN 17117600520 Throttle body - PN 13547588625 HPFP - PN 13517584461 MAF - PN 13627602038 DME/ECU - PN 12148604210 Exhaust manifold/turbo - PN 11657642469 Where it gets interesting is Pistons. Engines are different compression ratios. (10:1 for 28i & 11:1 for 20i). Basically 328i is just made for bigger boost.

@@EuroSurgeonNz hi what do i need to do to make 290hp in a 2014 320 the car has 328M complete exhaust downpipe charge pipe boost pipe injen evolution air intake but nothing done in the ecu if you can do something for me please let me know thanks

@@angelrivera439 did you manage? :D

@@EuroSurgeonNz Thank you for being so generous in your sharing of information. You have the most solid findings about the differences between the N20 in 20i and 28i guise. That piston + compression ratio explains everything

@@doug.report Would replacing the pistons be all that is needed to get the same compression ratio?

The only test to that is time. So far done 500+ of n20 tunes. Know of a car that we did back in 2015 with 30000km on the clock, done stage 1. Seen the owner about a month ago, car has 260000km on the clock. Had to replace few suspension components, nothing engine related. Good enough I guess? In general, N20 proving to be quite hard to kill if dialed in correctly.

Hey. Intercooler + Catless downpipe should be around 1200USD, than whatever intake you can get. Than set aside 1-1.5 for ECU + Transmission tuning on dyno. Find a reputable tuner in your area that knows N20 engines and you good to go.

Sebastian hey bud. Google european car tuners in your area, find someone who specialises in euro cars/Bmw and has rolling road. Tell them that you would like stage 1 for Ecu and transmission. Ask them if they do full data logging on dyno. If all checks out- good to go ;)

Eurocharged, and Midnight Speed Tuning are some good options in the Greater Toronto area. 11tenths and AMT Tuning are also a couple other options we have here.

What? That makes no sense where do you have that information from? The efficient dynamics version had 170hp The 320i started having 184hp in 2012 with the n20 and then got a facelift in the end of 2015 with the b48 continuing to have 184 hp

if you find me pre-2015 320i with B48 engine from the factory, I will buy it from you. 2015 was the start of LCi production where they replaced n20 with b48. and none of the n20s make 170 bhp, the 320i EDE made 170 with n13 engine.

Hey bud. Depends if on dyno or not. Google EuroSurgeon Performance, shoot me a message will put a pack together

just another 100WHP away from it ;)

On daily usage, there’ll be a small difference; but if you floor it, you’ll see that it’ll rise drastically since turbochargers are used for burning more fuel

Does a bloody good job at that.

Not sure i follow. So you tuned you 320D and that didn't make any difference? 2 reasons, either whoever done it doesn't know what they doing, or your car has a problem. Was it done on Dyno? or a guy in a van that came around and flashed it?

@@EuroSurgeonNz I mean there are "BMW - 320d - 2.0 - 161-BHP (01/2012 - 06/2015)" and "BMW - 320d - 2.0 - 184-BHP (01/2012 - 06/2015)", essentially the same car, but other one is 161ps and second 184ps, but after remap both of them will be identical 220ps. Where I am from, there was few of 161ps versions for little bit cheaper, and if I knew this, I'd have taken this 161ps version. I believe it is called the "Efficient Dynamics" version.

Hey Johnny. Our own modded pipe on this. Most budget version really. Next step - intercooler, intake, Charge pipes, and maybe even turbo.

I am in Canada is this a standard product also are you doing a tune as well?
