Once again, amazing work guys

[@vainohiltunen590]

tiiän ton tunteen kun kone käynnistyy ekaa kertaa rakentelun jälkeen. sen hieno hetki. onnee

[@tylerpurcell2149]

[@TidalSnow1]

Can't wait to see this thing hit the streets!

[@iliketorockrock]

Congratulations on the succesful start! cant wait for more vids!

[@xikods1]

Awesome... Just found this channel! Subbed, and just watched all this build videos, cant wait for more!! Keep it up guys

[@pazi88]

Thanks a lot!

[@maxpower700]

heck yeah! cant wait to see it roll! and the idle; my friend had a e34 535 (m20) with some mean cams and a big straight throu to the rear, thing sounded like a hungry bear thats been woken up in the middle of winter. the thing shook the ground when idling :D

[@pazi88]

yeah I'm interested to hear how this will sound at normal idle level (around 800 RPM). The cams aren't anything crazy but should still sound quite different than stock.

[@OhTittiez]

Love the channel so much I've decided to turbo my e36, but should I swap my m50tu for a m52 iron block or m50 non vanos or just boost the m50tu?

[@pazi88]

Boost the m50tu. Nothing wrong in that if you already have working one.

[@OhTittiez]

wow thanks for the quick reply lol, currently forum crawling to see what all I'll need but if I stay with my current engine it will just be turbo stuff and not entire drivetrains. only thing im worried about is my cyl 5 spark plug is time-serted and I dont know about boosting a head like that but I think I remember you had a vid where you installed time serts on a head but i dont think it was spark plug

[@ZinniCx]

Very impressive! :) Nice build aswell

[@azaza808]

Nice work once again! Can you do a video about megasquirt to show us more about the ecu in general? like upgrading firmwares and the inputs and outputs that you can use? that would be awesome! keep going with the videos cuz we are always waiting for them!

[@pazi88]

azaza808 I will do ms3 build from scratch for my m52 turbo so those will probaply come in that. And the base board is same in ms1,2 and 3 so those things will apply to all versions. I'm just waiting for my kit to arrive so I can start.

[@azaza808]

pazi88 awesome! We are waiting!

[@michaelmilberger9013]

your TIG welding makes me lay down and cry

[@pazi88]

Michael Milberger As I said we are not welders ;) The guys that lay down perfect beads have done that every day maybe tens of years. So much that it's like an art. Our welds are just welds made for use. Not a single weld that we have done has ever cracked so it's fine for us.

Hello sir, I want to ask, which the turbo inlet oil feed come from? the one with a blue around it or the another port? Thanks Your whole series very useful ^^

[@larbi3568]

Hi,I’m building an e46 328 turbo ,gt3582 turbo,3” intercooler pipework,turbosmart wastegate with arp head studs,cosmetic 0.140” gasket,850cc injectors,Walbro 450lph fuel pump,Audi rs4 maf sensor and stock eco tuning with romraider an tunerpro. What bop figures do you think it can make realistically? This is my first build and have been inspired by your videos,keep up the great work 👍

[@pazi88]

Maybe 500hp. Depends mostly how much you dare to push it.

[@thuni4056]

Modify the compressor housing ? why ? Nice work and hello from the Czech Republic

[@mohamedmostafa-zc5ju]

very helpful thank you....where can i get fpr like that?

[@serbiannationalist1466]

Hello guys, great work. I have a question regarding my M50 engine. When i push the throttle. there is sound coming out of the Throttle body (HISSSS) it sounds like a huge vacuum leak, but when i put my hand against the Throttle body flap, its pushing air out of intake manifold (only happens when i stomp on it) The engine sounds like this *kick the throttle* - HISSS-(0.5sec) Then the RPM's are roughly rising (sometimes the HISSS is followed by small explosions) The car accelerate very jerky and slow ( followed by "explosions") the vibration of the engine is slightly increased since this happened I suspect that one coil is bad since its not original for M50 maybe CPS or bad fuel pump?? is it normal for air to go out of intake manifold (idk but i think that should not happen, maybe the cams are adjusted wrong)?? Thanks in advance.

[@pazi88]

Don't know. i'm not very good at diagnosing engine problems by the behavior. I just plug in a PC and see from live-data what is happening and what is wrong.

[@gespinal0301]

congrats!! can't wait to see what times is pulls. Also where did you get the washer fluid reservoir?

[@pazi88]

Gabriel Espinal Thanks! Ot's just universal one we found from local autoparts store. You could search eBay if there would be same ones for sale.

[@runesmDK]

Why did you change the coils? The stock ones can keep up just fine with a lot of boost

[@pazi88]

Yes I know but the stock ones were old and crusty. And one already broke. So new coils were needed and these used ones were cheaper than new OEM coils, so we decided to get these instead of new OEM coils.

[@mostafaabubaker669]

Such a nice journey till now! keep the good work coming mate :D! It would have been quite nice if you mentioned the price of every party you buy.. Or just tell me what's the total cost of the whole build :D

[@pazi88]

Thanks a lot. Listing the price off all the parts is quite useless. Because the prices change from time to time it highly depends where you are buying the parts. For example we bought the pistons from UK in time when the brexit took down the UK pound and because of that we got the pistons for less than 1000€ including shipping. At the moment the cheapest price for the pistons looks to be close to 1200€ without shipping...

[@mostafaabubaker669]

Anytime mate.. And thanks for the info.. :D All i want to know is average cost of a well-done turbo build that's all :)

[@Michael45P]

Do the coils make that big of a difference ? Good luck with the project !!

[@Mortalomena]

big bad spark is good

[@pazi88]

No. The coils are pretty much on/off thing. They either are enough and the engine runs fine. Or they aren't and the engine starts misfiring at boost or something like that. You won't gain any HP by changing coils.

[@madmike5144]

Onnea onnistuneesta ekasta startista :)

[@ItsMatich]

What is the recommended MLS head gasket thickness for turboed m50 nv? Do thicker head gaskets cause reliability issues in the long run?

[@Levi_levite]

I have an M50b25 with its harness but it's running with an M52 crank pulley and I have noted that the pulleys are different. What firing order should I use for the car to run I came t find any chart on the net. It's swapped in an e28 chassis

[@allisterkold3987]

thank you

[@boostv8chevy457]

Hi friend. I forwarded this vid a little bit. so I am not sure if you have show it already in the prev. videos. are you using the OEM ecu of bmw? if yes. can you tell me what I need to tune the oem ecu? can the oem ecu be tunable for max power? or how much power you can geth max of it? with type of turbo setup of response best with the M50? I like to have big power with low rpm stock internal and very little turbo lag. I don't want turbo lag or to much.

[@pazi88]

We have KDFI v1.4 in this which is just PnP megasquirt 2. If you have M50 then you at least need eeprom programmer and tuner pro with working XDF files to be able to tune that. But I don't know more about that. Also you could just buy set like this for the stock ECU: www.trmtuning.com/product/e36-obd1-turbo-tuning-package/ With m52 you can tune the stock ms41 ecu really easy with less than 50 bucks investment. Check this video for more info: kzbin.info/www/bejne/hYOpg62PgbJ9aZY

[@boostv8chevy457]

HI pazi88. thank you for soon reply. I have a E46 2001 two door. It came with 4 cylinder. so I like to put a 6 cylinder in it.So I not have the engine yeth. I can have M50 Or M30. I have so few knowladge about BMW. I will have a look in the link you sent me.

[@pazi88]

If you have e46 I would get m52b28tu or m54b30 duoble vanos engine which those have come from factory. And definitely stay away from ancient m30 engines :D Much more modern engine, it will go in bolt-on and all the car electronics will talk with the ECU. The stock ms42/43 ECUs can be tuned with cheap tools by everyone (videos about that coming soon).

[@mattpur8486]

Hi pazi, i have a question for you. We're now building m50b20 turbo, and we are planning to use kdfi ecu, should i use stock MAF sensor i heard it is better to use MAP sensor instead, or somesay you dont need any of these, u mentioned it in your video, that you will not use speed density as a calculator of fuel. So what would you recommend? MAP sensor would be the best choice ha?

[@pazi88]

Yes map sensor in speed density mode is the way to go. The MAF could be used, but in KDFI it isn't wired in at all. And also stock MAF is not suitable for turbo setup. Ypu would need much bigger MAF than that and know transfer curve for that. And I would recommend not to use KDFI and build m50 pnp speeduino.

[@mattpur8486]

@@pazi88 why would you do pnp instead of kdfi?

[@pazi88]

@@mattpur8486 Because kdfi is unreliable and speeduino much cheaper.

Riippuu mallista. Tuo on ainakin sileä sisäpinnasta, että pitäisi pelata kuten normaali putkikin. Lisäksi jotku menee kurttuun imun voimasta ja pahimmillaan tappaa kaikki tehot. Tuon päällä näköjään kesti jopa seisoa, että jospa tämä ei menisi kurttuun. Tuota ainakin myytiin nimen omaan tähän käyttöön tehdyksi. Joka tapauksessa laitetaan GoPro konehuoneeseen seuraamaan ko. putken käytöstä, että näkee meneekö se ruttuun tai muuta outoa.

[@Mek00071]

what kind of ecu you use in this m50?

[@pazi88]

Mek00071 It's KDFI v1.4 which is PnP megasquirt 2.

[@Mek00071]

pazi88 Is it some kind of stand alone?

[@pazi88]

Mek00071 Yes. It doesn't require stock ecu.

[@Mek00071]

pazi88 You write very quickly :) What do you think about the ecu type of piggy back? Like det3? I try to build myself just like you my m50 at 300hp

[@pazi88]

Mek00071 I just hapen to sit at computer currently :D I would stay away from the piggypacks. Those are really needed if you need to for example have all the emission stuff and OBD compliance stuff working and the stock ecu is not tuneable. m50 is so old that there isn't need for such things and you can get standalone for same price.

[@allisterkold3987]

pazi do you have email, to ask some questions, I would like to confirm wich wastegate do I have to buy, the people recomend me tial or smartwastegate, 44mm

[@pazi88]

tial / turbosmart 44/45 mm wastegates are very good for most tuners. You only need bigger one for crazy big turbo.

[@TidalSnow1]

what gauge setup is that

[@pazi88]

it's just some cheap gauges from local autoparts store mounted to steel plate.

m50 vanos or non-vanos? vanos and m52 use same crank pulley. if it's m50 non-vanos, drill new alignment hole for it to match non-vanos one.
