How to turbo BMW m50/m52 engine, part 3 - Turbo oil and coolant lines 

+Gyikhuszar Thanks!

Well yeah why should I delete these :D Though these have some things I was wrong etc. but still lot of useful information.

@@pazi88Thank you so much for these videos, i will watch all of them. Next year I want to put a turbo on my M50 e36, and I'm sure your videos will help a lot. 😌

@@milanswat4 Great to hear that 😁

pazi88 very helpful thank you! Building my engine today

This is based in physics and is a really great trick for when you aren't able to use a device to measure. Torque (Nm and ftlb) is based on linear displacement. It can be written as "t(orque)=F(orce)r(adius)" 1Nm is equal to 1 newton of force at a distance of 1 meter 1ftlb is equal to 1 pound of force at a distance of 1 foot t=Fr=1*1=1 For example, if I want 200ftlbs on a bolt, I could put: 200lbs of force 1ft away. t=Fr=200*1=200 100lbs of force 2ft away t=Fr=100*2=200 50lbs of force 4ft away t=Fr=50*4=200 etc. etc.

Yep that can be calculated by simple physics formulas. As I did :D

Mukava että kelpaa. Uutta tulee, kun kerkee muilta hommilta tekemään.

Thanks!

No problem you guys are very helpful and quite cheerful love the attitude and all:) I hope one day I can work with people like you guys!

Of course it could. However, due to the engine angle, just bolting it straight to the oil pan wall isn’t a good solution - the oil line will loop up slightly, meaning that oil will get trapped in the line unless you use a scavenging pump (which makes the system more complex and expensive). Removing the sump for modifying is also more difficult with this chassis and engine combination since you either need to lift the engine or drop the front subframe. In addition to all that, draining to the front cover means you’ll have a shorter line, so it drains better. Also, in a low car, breaking a sump isn’t uncommon, but that then means fabricating a new sump. Probably more reasons to it, these are just off the top of my head.

Thanks. I have tried to add Ebay links to the parts we have used in the videos to the video descriptions. For example the exact eBay turbo. I would be pleased if you buy the parts using my links, I will get small cut of the profit. it doesn't cost you any more than buying without link from eBay ;)

+Andrew Savill Thanks! If the e36 is you daily, I wouldn't recommend but if it's not, go for it! (These DIY turbo engines tend to bit unreliable, so that's why I don't recommend to do it to daily driver).

Look up mcm how to turbo a car if you want reliability you can't go wrong listening to turbo yoda

+Crysis Contained Tuuuurrrrrbbboooooo Yoooooda (He's a Turbo Yoda) I watch Mcm :) Turbo is off the table as car is costing too much lol

+Andrew Savill I have a 92 e36 325is that I'm going to be pulling the engine and rebuilding soon (it definitely needs it) when I have the room, time and parts to do it (slowly gathering the parts) and I'm going to turbo it while the engine is out and thinking about experimenting with twin charging because why not. Only thing I haven't figured out yet is where I can find a shop near me to tune it (no performance shops where I live)

Twin charging is good setup if you have big turbo. With "small"turbo (less than 500 hp) it's not very feasible, because you can make it spool very low. And i wouldn't recommend the twin charging setup as first boosted setups, because it's much more complicated to build and tune. There is enough to figure out with turbo only. Then go to the twin charger setup, when you have more experience.

+BuiltT5 This kind of adapter: www.sw-tuning.de/en/y-adapter-M12-X-1-5-for-oil-pressure-gauge::25708.html

Nope. It will work fine.

+E30ny The part 4 may take few months, because there is lot of going in my life currently. But the car should be ready for next summer, so all of the episodes should be out during spring.

+EuroGarage If I remember correctly, those are these ones: www.ebay.co.uk/itm/Universal-flares-fender-flare-wheel-arch-extension-arches-trims-jdm-wide-set-e-/252150761680

Yes alu block. And yes the iron block is tougher, but it's really needed in really high hp builds (+600hp)

I'm running the turbo oil feed from the same banjo as the vanos oil feed with double banjo bolt. No problems in that. This m50 doesn't have vanos so the the vanos oil feed can be used for turbo oil feed as it is.

+Tommy It's vw golf mkIII booster. You can find same kind of boosters also from mkI and mkII golfs. The part number should be something like xxx 612 105x (x can be anything) and it should fit with minor modification. The modification that it will need depends which car you can get the booster.

For bigger coolant lines I like to use the bmw oem clamps and for smaller ones I like to use the one-time use clamps that are also used from factory. Because of the sweet sweet oem look :D

+Czachan Not sure what you are asking. But the turbo can be mounted to 2.0 m52 in the same way,

Anttu Silander Joo pitäsi riittää.

+Zuze91 No those are just some universal adapters from local auto parts store. Not the best way to do that, but very easy and cheap.

Check from 4:20 onwards. You can put double banjo bolt to the vanos oil feed line and have the oil feed for the turbo from there. No need to tap anywhere.

Awesome thank you so much

Part 4 and 5 are already filmed. I'm currently editting part 4 but there has been delay, because I upgraded My editting PC.

+myrakas86 Some of the turbos need the oil return to be over the oil level in the sump. For example Holset turbos will smoke and consume oil if the oil return line goes to the sump. I don't know if this particular turbo requires the the return line to be over the oil level but I made it to the front cover just in case. And we may use bigger Holset turbo in future, so in that case we don'n need to change the return.

+pazi88 Ok, thanks for the reply. Didnt consider that for a reason, but will keep it in mind.

bdusanek There will be extra oil coming out of breather

Mikki Hintikka Kaasuläpällä on nestekierto, että se pysyy pakkasellakin lämpimänä, eikä jäädy umpeen. Tällä ei ajeta talvella ja jos ajettais, niin turbo varmasti pitäs kaasuläpän muutenkin lämpimänä, niin koko nestekiertoa ei tarvi. Ja turbo kyllä toimii ihan normaalisti tässä. Olet ehkä käsittänyt jotain väärin.

pazi88 kiitos! en osannutkaan ajatella että se olisi lämmitystä varten. ja katson vielä kerran uudestaan että näinkö teidän setupin väärin!

Joo kyllä.

Just some cheap helicoils from eBay. Not genuine stuff.

I mean what are diameters? I don't know whitout bolts in hand.

M8 helicoils. You can check the bolt sizes from realoem for example: www.realoem.com/bmw/enUS/showparts?id=CD11-EUR-05-1995-E36-BMW-328i&diagId=11_1288

+MyKnifeBeLike Stock compression. This will be run on ethanol, so that's ok. No rings at the moment. We will upgrade the head gasket when it fails.

+pazi88 i want to work with the stock ecu on 0.8 bar without ethanol, do u think i should go less on compression?

+MyKnifeBeLike It's doable but make sure to use premium (98 octane in EU) fuel and be very careful with the engine tune. The stock pistons will crack very easily if the engine knocks. If you are using stock ecu from m52 (siemens ms41)it has very good knock sensing, so it should do very well with good tune and correct maf+injectors.

This was always leaking little bit, so we wanted return that doesn't leak.

@@pazi88 And the AN bulkhead fitting that you use now won't leak?

Yes these are street legal in Finland when there is less than 203hp in use at street.

thats good to know, thanks!

Öljynsuodattimen päässä m14 ja turbossa m10 tai m12. En muista tarkkaan. Kumpaakin kokoa tainnu olla.

Cherry Hall anturit siinä on ollu sen jälkeen kun siirryttiin kdfi:stä pois. Ei mitään ongelmia sillä rintamalla.

The PIANA Meth Pills Diet No it can't. Or maybe for short time. But with forged pistons and connecting rods and it can take +1000hp

What about m52b28 iron cast bottom, m54b30 crank camshaft + m50 intake. Stock rods/pistons. Is it reasonable to think 375/425 hp ? Mls cometic 0.140 HG + arp head studs

+ville hytönen Ei enään samaa ollu myynnissä, mut näitähän on ebay täynnä. Tuossa esim. aika samanlainen: www.ebay.de/itm/Burstflow-Turbolader-BT-WGT30-70A-R-bis-368-Kw-500-PS-V-Band-mit-WG-universal-/261841764365?hash=item3cf6fc400d:m:mRpQm-bDeTrvolFHAa_5lGw

Yes. Perfectly fine with e85. I even went almost up to 12:1 on my latest build.

+fellowship of the goat Most of the turbos require the oil return line to be above the oil level. Otherwise those turbos will start to burn oil and smoke. You can't get the return line above the oil level by installing it to sump.

Oh ok, fair enough. Noted for when I do my M42 turbo build. In regards to the feed, I imagine that the oil pressure is enough to push the oil uphill into the turbo?

+fellowship of the goat Yes there is no that kind of problems in oil feed. Only the oil drain is critical, but how critical it depends of your turbo. But in general make that as big as you can, no uphill sections and it should end above the oil level in engine. Otherwise you might end up with smoky turbo.

OK, thanks heaps man. Great videos, I've been in your thread on r3v since the start, big fan of the cars. Last thing: how much of a difference does the E34 rear end make?

It's named w30gt at eBay. There are dozens of Sellers for these chinese turbos.

Ihan itse kokeilemalla ja netistä tietoa imemällä :D

knives4apro Saunders It's e30 m3 cover.

pazi88 then i have no chance in finding one of those. lolol. i might just hide the wiring under the firewall or guards. thanks pazi. love your vids man

just buy new. It's something like 20 bucks.

Paint skilz!

Mikäpä siinä. Oon minä niitä säätäny vakio moottorinohjauksella turbolle jo jokusen.

Miten tuo kone kestää turbottamista?

Hyvin se kestää. Noilla on nyt minun säätämänä ajettu 0,5 - 1 bar paineilla avaamattomilla koneilla. Bensalla sekä viinalla. Kansipahvihan noissa on vakiona jo MLS mallia, niin se kestää perus massatiivistettä huomattavasti enemmän painetta.

Missäpäin vaikutat jos saa kysyä?

Oulussa.

+qweqweawea asdascxycyx This e30 has been built with minimum budget right from the start. It's not like we don't have money, but if there is not much money spent to build the car, we can beat the shit out of it without worrying too much. And these m50/m52 engines are dirt cheap so if the engine breaks, we will just buy new one with couple of hundred bucks.

Yes that was removed :D

+warro007 No jes :D

Thanks! It's before filter.

You dont want it after?

It hardly makes any difference. There shouldn't be any metal particles in the oil and if there is, it always means engine rebuilt and the turbo has to be inspected also in the process.
