As it was a quick mild tune, it never went to a dyno, car is still running great tho.

@@tegli4321 Il check if i have it somewhere, if i do, sure.

@@TomoReso okay, thank you so much, i am waiting for your response 😊

@tegli4321 I am sorry I do not have it any more...

@ do you remember what have you done on the disa map if you have changed something on it?

@tegli4321 I have changed it, along with intake and exhaust vanos full throttle, ignition, and raised rpm 7200... i could rework your map maybe, if i have the definition file for it... do you have the tools to read and write to ecu?

@@ivanfilipovic3296 Yes i do, nobody is talking about n52 single stage disa intake manifold. I believe it would do great on m54 engine without any drawbacks. Making ports for injectors should not be a problem, but time and money is :D. Also I dont know if it would fit in terms of size and angles. Apart from n52, n54 manifold with spacers is really interesting and tempting to me. ITB could be good, but its the most expensive route.

@@TomoReso so happy to not hear m50 2.5 intake for once, overjoyed actually. Around x-mas i will port and polish my own head and have it as spare so race is on for the biggest outputting m54 NA in Croatia :)

@@ivanfilipovic3296 Its a deal. :)

I should have done that, I have searched and found out that dimples work too, but at the long radius. All of this is really addictive stuff to me, but there is less and less time as life goes on... :)

You are welcome! I wanted so many times to upgrade this engine to something newer, better, but it has been so reliable that i just dont want to change it. And I have been giving it quite a hard time many times...

Its way too long gearing, good for daily tbh, but not for acceleration.

​@@TomoReso well, 0-100 seems quite good, ~5 sec. then from 140km/h it couldn't catch up breath. for daily street driving I guess it's fun to drive. I've got M54B25 and was thinking about M62. for street purpose it would be enough I guess.

@@luptakt its just like you said. For b25 it would make a lot more sense, if you can make it for cheap, its a great little mod.

​@@TomoReso one more thing. M62 was used on US 3.8l cars. so it depends what you expect from supercharger, what is your power goal. the problem of this is, that with turbo, if the power gain is not enough, you just replace turbo, give it larger intercooler and you're fine. with eaton M90 or M112, you need to start from scratch. custom bracket, custom piping, another belt, etc. nothing fits. I'm not going to race with it, but I'm sceptic... so exactly as you said, if you can dyi it completely for cheap, then it's great little mod. unfortunately I have doubts that I can completely dyi it. :D

@@luptakt m62 is easy to fit as its quite small, the biggest hussle is to make a bracket or carrier for it and align it perfectly so the belt is nice, tight and straight. The rest is not a big deal. You forgot that tuning supercharged engine is far more simple then turbo, and does not require often a new ecu/standalone. IDK, if you were close id gladly assist you.

There was a forum with head flow comparison, m54, m50, s54 etc, and there it was clearly shown that m54 stock intake is the worst. I can make a video of what I did, basically I have cleaned up the intake port, there is a lot of cleaning to do. Not only the cast marks, but uneven transitions etc. Most of the time ive spent around the valves and valve guides, I did not enlarge the port openings even one bit. I did the same for exhaust side, but there was far less job to do as I remember. Do not port the shorter radius side. You want smooth consistent ports with nice transitions, larger is not always better. You want the size to be efficient and just enough to not choke the engine. What I did also was add an angle to the valve seat and the valves as well. Ive also modified the chamber side of the head as well, when valves open a bit they have a flow path all around them now, unlike before. If you are not in a hurry I strongly advise you to look up David Vizard on yt, he Is an elderly man extremely experienced and has a lot of videos explaining what works and what doesnt. Also put video speed at least to 1.25, youl get why :D. I really think I did a good job, there was gains and no losses, but sadly I can not prove it now as I do not have the logs no more and an engine is supercharged. I could tho remove the supercharger and make few more maf logs and compare it to other engines. I urge you to do logs before and after.

@@TomoReso Thanks a lot for the super detailed reply! I was planning on installing an M50B25 intake manifold (which ideally needs port matching - hence the original question, why not go a little further, especially with the cams!), Schrick 272/256 cams, Mahle forged 10.5:1 pistons... the goal is to make it a nice OEM+ street engine with proper pulling power up to 7k. The car has currently got an M54B22, and I definitely believe a few horses have left the stable. It already has a 3.38 diff from the factory and even with the cams and M50 manifold, the B30 will make a good bunch more torque than the 2.2 so I'm fine with that. As long as it pulls hard above 4k and sounds good, I'll be happy :D What tools did you use for porting? You did everything yourself, without any professional help, correct? I'll definitely look up David Vizard. I was planning on learning how to log and remap with this project too. A friend has experience with remapping on E85 so we'll work on this together. Especially given how much info there is out there! Thanks again

@@nvl2691 M50b25manifold produces awesome sound above 6500rpm as to where m54 dampens the sound a lot. Powerwise dont expect a lot from it (manifold alone). It seems like a cool project, will sound and feel nice. All of the work I did myself, using basic cheap tools. Electric drill with cord extension if its called like that, and various bits i got with it. Also spraying wd40 on aluminium or the bits every now and then keeps the bits from filling with aluminium, makes for the better work. Took me about 15+ hours to port the head and valves. Could be done faster ofc, but I always think like i have to do it only once, slowly and patiently, and ive made no errors in process. I actually quite liked the porting job, was fun. Always glad to help if I can so no worries.

Great results and advice, if you could take the time to make a video and discuss it, I'm sure it would benefit the M54 community. Thanks!

@@TomoReso what do you think about porting m54 exhaust ports to the same size as the exhaust manifold and the gasket?

of course. you have a map called full load enrichment, so ive set my supercharger to activate only on full load, then with additional air additional fuel comes. Perfect ecu for supercharger.

no, i thought of installing one.

go for either of those two, tho it will be more complicated due to supercharger size. Powerwise m62 makes little sense, m90 or m112 are way better.

@@ACuriousManontheIsland you should look for rotor slack and rotor coating, if it has a lot of scratches or if coating falls off it becomes less effective. Try to spin it with a drill and listen. Look up on youtube as well, there are videos about it.

@@TomoReso hvala cim sredim djece bolesti auta prebacujem se na tuning hvala ti jos jednom

It will, yes. There is quite a lot ignition advance on this little engine.

It does not look fast yes, but looking other videos on yt, it does seem on par or faster then many...

lol slow what u mean thats very good for 220hp and its weight why talk nosense.

You can't push that much torque on stock turbo, if you have dyno figure with that much torque then it's a fake dyno. Do a 100-200 kmh with dragy or gps and check it.

@@piovo1 yes you can push that much on b47. You need intake and downpipe

@@PKperformanceEU 240bhp doesn't mathematically make sense with only 500-530nm on a 4 cylinder diesel. 240bhp is a max 460-470nm.

You should be worried, the car was my brothers, then we sold it to a friend. It has known history and was serviced every 10k km. His timing chain broke in the morning on literally no no throttle, 50 meters from his house, at around 1000rpm. There was no chain noise, i have changed few chains already on other cars and i know what noise to listen to. So, my advice, if you like your car and would like to keep it, plan to change the chain. Dont go for cheapest chains, but swag brand is durable enough, best would be oem.

eaton m62, small supercharger.

Those engines are bulletproof if maintained properly. Same goes for e46 as a car. Engine as an engine is really reliable. IMO if it does not consume much oil, like 1L per 1000km, you will be fine. If it does not consume oil, the rest is simple, few gasket changes, sensors, rubber boots, not a big deal if needed. Its a great car and an engine to own if you can do the simple mechanics yourself. The community is great, many parts available, and its an never aging design. I will own one e46 ci myself one day. Its a blast on a track day with it, beautiful daily car with just enough of tech with it. If you do decide to look it up, please take it to a lift, check for cracks at the subframe mounting points on chassis as well as front suspension tower cracks (if its called like that). Check for corrosion too.

6000 is way to expensive. I bought my manual 330Ci M-Sport II for less than that and with 223'000 km (it's my profile picture, miss it terribly). I just bought a 320i 2.2 Touring manual with 289k km for... 300 euros. Running and driving

@@nvl2691 thats great value, however in my country, prices went horribly high for an e46 coupe.

@@TomoReso Coupé prices are similar here. But you have to be patient and quick when the right opportunity arises. Plan for the Touring is rebuilt M54B30 swap and retrofitting the rough-road suspension package, should be some sort of rallye car thing that I can drive through fields whenever I want to

@@nvl2691 sounds fun

yes, i noticed heat soak with stock intercooler, it looses hp on longer runs... those are some good numbers, 326hp! congratz

How's the 8hp45 holding up?

I have same engine 285hp but its slow…acceleration is like 240/250hp its so slow for 285hp merc e350 250hp gaps me…is there a problem or it is normal?

yes, something like that. 0.5 on really low rpm, 0.3 mid to top rpm

​@@TomoResoWhy don't you increase the pressure?

@@harunpolat7628 because this small supercharger is already on the limit, at 7000 engine rpm it spins about 15600rpm... max safe limit is suposed to be at 14000 rpm so.... also for an e30 300hp is enough, only recently when i put 225 tyres its balanced nicely, in future i might go 350 to 400hp but with turbo combined woth this supercharger.

@@TomoReso What is your ratio?

@@harunpolat7628 2.17, 210mm crankshaft pulley, 96.5 or 98mm stock supercharger pulley, i forgot :D

That was my car setup originally, its decent yes.

Exactly, maybe in near future i will go and remap it again, this time loaning a dyno, to see what is it capable of.

@@TomoReso You could do knock map whit rr it was around 30 some for me if i remember correctly, throwed 50€ b30 cam there but base tune is useless whit those and most gains come from ignition tune anyway since its so mild.

@@TomoReso You might want to eyeball b25 fuel maps and full load maps a bit once you go closer to knock limit whit ignition tune.

@@winha1435 that is more or less what i did here, i went slightly more agressive then b25 with ignition. Fuel is not needed to adjust. Weirdly enough b22 has more ignition advance at low to mid rpm, less up top. I dont remember what i did with vanos and disa. I did do small adjustments too.

@@TomoReso it has so much so at low that rr register it as knock, b22 factory bin is a fuking mess :D theres some randomnes on b25 maps too, it looks like b30 is only one that is ironed out.

3.45 is probably the best.

Somebody saying 1 and 2 very low with 3.46 . Whats your top speed with 3.64

@@aniluzun2321 yes, you need 3rd gear to reach 100kmh, very short gearing, but in my opinion by far the best ratios, really gets the most out of b28 engine. Top speed with 195/50R15 and 3.64 diff (e39 gearbox) was about 210kmh @7200 rpm, gps speed. For 3.45 diff @7200 rpm it would be +10kmh, so about 220kmh gps. 1. gear max 53KMH 2. gear max 88KMH 3. gear max 135KMH 4. gear max 185KMH 5. gear max 225KMH I currently use 2.65 and for daily its great, but it kills the acceleration a lot even with m54b30 (3.0l) engine.

@@TomoReso whata your offer for me bro, i have m52b28 engine Zf 2.8 5 speed gearbox 15 bbs with 205/55/15 / 215/55/15 3.64 or 3.45 i. I could not decide. I don't want it to be bulky either.

@@aniluzun2321 well, best improvement i ever made on e30 was 225/45r16 handling wise, and the feel is just right! I would go with 205/55R15 which is right dimension for E30, or 205/50R15 which is wrong, it will read wrong KMH, but looks better. 3.45 is very good ratio for E30 with around 200hp. 3.64 is maybe a little bit short, but good as well.

Sadly I dont. I do remember I was cutting it and welding it, you can see the placement ive made on this video. I dont remember about the cable either, I usualy work with what I have at hand. The cable had to make 180 deg turn to pull a throttle, which isnt optimal but it worked flawlessly.

@@TomoReso yeah i saw. I think I might gonna use a rhd cable to get some extra length. 🙂 Did you change anything in the tune for the bigger injectors?

@@FilipBorjesson yes, ive used m52b28 pink injectors for correct spray angle, and ive had to change fueling by some percentage, i cant remember how much, i think it was 10-15%. Maybe i can find the map, i think a friend of mine has it still on a laptop, as back then i used his laptop for the tune :D

@@FilipBorjesson here you go, to the left is stock m52tub28 fuel map and full load enrichment, to the right is m50 intake on it and pink m52b28 injectors. I see i have actually added more fuel, not less, meaning they were smaller then original injectors... i.postimg.cc/65DW7WHv/image-2023-08-13-193315368.png Also, there are gains in ignition timing and vanos settings (even with original intake manifold). But this is best to be done on a dyno. Also its worth to mention ive used wideband o2 sensor to dial the fueling, 14.7:1 idle, about 12.5:1 full load.

@@TomoReso I'm now complete with the conversion but the car runs very bad. I haven't used your table yet for tuning but the pink injectors should be bigger than the stock long tip ones. I might change to green m50 injectors and try if that will improve the engine.
