- New engine build just completed. Head reworked, and CNC'd by NG Motorsports in Germany, along with extensive seat work. Wossner pistons and rods fitted. 12.3:1CR, and 86.75mm bore. Schrick 284 cams fitted. I've built this one from the ground up, so am feeling confident in it's longevity. Fingers crossed...
Thanks for the kind comments Gents. I'm now building a VAC Motorsports 3.4 stroker. I'm hoping to finish it next month, so will make a similar video of that one. :)
Mikey Mike 👍🏼 what power are you making with this race engine? Rev limiter?
Mikey Mike great work mate would absolutely love for you to build my S54 NA stroker! I live in Australia though, if I were to organise freight is this something that could possibly be arranged in the near future! I just want a high comp, high revving, NA 3.4-3.5L, with the balls to match! Would love to have around the 500-550bhp mark but don't know how possible that would be NA. Engine is out of my 2005 E46 M3 CS btw.
Thanks for your time mate!
Can u show in detail with explanation so so we can do it bye my self
It's a work of Art. Beautiful engine build !!
oh my god! Is very, VERY beautiful!!
Thank you very much for the compliment 🙏🏼🙂
Wonderful Video, no Music, just Engine Porn :)
The clearence on the mains look healthy, did you still know which clearence you get on the rod bearings and which bearing manufacturer you used? Thank you!
53Fatman thank you for the compliment. I used standard BMW bearings, as they seem to last very well, and I think they are kind to the crank. Rod bearing clearances were 0.038, or thereabouts.
Has this video been posted on a forum or Facebook group? It seems to be suddenly getting a lot of views, these past few weeks, so I’m curious as to why. 😊
@@mikeymike6017 its the youtube algorithm :D
Whey, what did the dyno said?
Awesome build! I see that you're using a lower thicker radiator (probably for a carbon intake). Which radiator are you using, and how is it keeping the engine cool? Thanks!
I would love to invest in a motor so precisely done
Race engine with vanos? No need for vanos when you wanna race. Absolut bullshit to keep the vanos. Nothing to see her. Just a guy with money and no dyno run. Many people ask for it but all they get is "i have more S50B32 and i have... i have.... i have" .... but what you don't have is a dyno run to prove your work.
get yourself a life
just thinking about 284cams as I have to dissamble the engine again (something knocking inside, but not the bearings or rods, sound comes from the vanos or the the vanos-cams connections). Do you recommend something more with the 284cams? I checked schricks catalogue and it showed that 284 can be used without any problems with the use of the stock head parts (springs etc...). I'm thinking of a carbon airbox with a tune, but I'm not sure where to find a good tuner in this poor country (Hungary :) ) and without a tune the 284 cams looses a lot of torque around 3k rpm as I've seen it on dyno papers.
thank you for not swapping to s54. The s50b32 is a work of art
KXF MX hahaha... thank you! Many people think I’m crazy, but I actually believe the S50B32 has some good points! Whilst an S54 will in theory make more power in standard mechanical form, I believe the valve train to be more intricate and susceptible to wear compared to S50. I also feel that the S50 rod bearings being 2mm wider, will wear less, and also that the S50 doesn’t suffer head gasket failure. Just my ‘thoughts’ though.
Im currently building an s50 b32 with accesssories to fit into my bmw e30. I cant wait to finish it!
Beautiful job! I have got the same race car but with high miled stock engine...planning rebuild. Do you have an adress, link for this cooling radiator ? thanks!
Gegette laburette ,
Thank you. The radiator and airbox were supplied by Martin Hollands of MS Motorsports in 🇬🇧. If you have trouble finding his website, please reply again and I’ll find it for you and post the link
@@mikeymike6017 www.raceparts.biz Thanks! One more question, did u had any cooling issue during hot trackdays (+30C)?
@@gegettelaburette2145 I've not done a track day in anything more than about 26c, as the car doesn't have aircon, so it's like a torture chamber in there! But, I think the cooling system is only-just good enough at that temperature anyway.
As awesome as the golf balls are I don’t think they’re very helpful since gum and varnish can build up in them
Shame on you! Couldn't clean up the bay a little? Haha jk looks great. Update?
Very nice
Been off the spanners a little while but that golf balling as part of the porting process is a new one to me, any ideas how it's done?
I went incognito to watch this
I see what you did there ;)
Why would you bother with a S54 when you got a S50B32
What's the performance difference doing a golf ball or straight polishing?
I'm saving up right now to buy my motor. What u have done here is absolutely amazing. Absolute perfection,something no other manufacturer could ever do. I mean 300+hp(I'm being conservative cuz I missed ur exact number)outta a 6cyl N/A motor(hell I'm impressed with the 220 my car has lol)
Im building one right now!
I'd love to build one of these engines very soon. How easy was it to work on this engine?
Great job!) I have rebuilt my S50B32 too but, i used berner black rtv so there is oil leakage. What you advice to use between cylinder head and intermediet housing? RTV or anaerobic sealant? Also which brand you advice?) Thank you🙏🏻
Hello freind, in my experience all face to face fit which requires sealant with no gasket should have the anaerobic sealant. Used on honda k series engines and works very well!
I believe the Golfballing inside the head would be more efficient if the golfballing was done after the intake and exhaust were first polished and then textured
Hi Patrick,
The ports were first CNC machined, and then golf ball textured. I believe that ports are generally not highly polished, but usually have a brushed appearance, to improve fuel atomization.
god damn so good do more videos in between photos pls
I'm thinking to put the 284 cams in Italy and go to Germany to mapping.
it's possible to run with stock software for a bit about 50km?
why you choose the 284 instead the 296° i mean, it's a pity that u rebuild the engine with everything, but not the head ? they could give you more power too
You should put it on a trailer just to be sure
Nice parts. But shitty work.
I'd like u to build a 1000hp 335i engine for me
How much would you charge for a this kind of rebuild more or less? I do own a S50B30 swapped E30 and I am planning a full engine rebuild sometime soon, but I do not trust many of the garages in the nearbies. Thank you.
Antton, I love building engines just for fun, but only if the spec is exciting. But, realistically I could only do maybe three a year, as the time detracts from things that I should be doing. I’m in the process of moving to Japan at the moment, and am taking a few S50B32’s with me, so I can have some ‘rainy day’ fun over there once I’ve settled in and built another engine room. It’s really hard to cost out an engine build of this kind though, given all the small details, like refurbishing aluminium parts. If you are looking for someone you can trust, I would give either Ben at Hack Engineering, or Terry at Butler Motorsport a shout. Both are extremely good!!
@@mikeymike6017 wow, that sounds cool, I am going to visit Japan quite often from now on due to a new job, we may meet in any japanese track haha. Okay, thanks for the workshop inputs, really appreciated and keep it up with the good work (Y)
Uuuuuaaall , excelente carro , muito bem montado , sonho de consumo , parabéns pela máquina
what is the weight of stock rods?
A thing of beauty
Es mejor que el s50 b 30
Bmw e36 king car love
Nice work!!!!!! Great car!!!!!
Dyno ???
Fuel?
Where did you get the gold ball porting and how much?
Martini is a wino NG Motorsports in Germany. They’ve just done another one for me. Can’t remember offhand how much, but the golf ball I believe can only be applied to their CNC porting profile, so you would need both done. I think it comes to around 1200 euros in all.
Nice nitrided crank.
Good lord. How much would you say it all cost?
ThatFly WelshGuy I’ve not actually costed it all out, which probably isn’t a bad thing. But, probably £8~9k of parts/services, plus my time, etc...
Nice! What's the lift on the Shrick cams? Any reason why you didn't upgrade to shim under bucket?
Hi Connor, the 284’s are 11.9mm lift. I have two other engines that have shim under bucket, one being the VAC Stroker, which I’m now resurrecting in a new build, and a P50B32. In this instance though, I figured I would just increase the spring pressures slightly, and go with normal shims, just for ease of servicing.
How are they to service? I've just finished my S50B30 build, running catcam's 1303410 set. 285° 12.50mm intake and
277° 12.00mm exhaust. Went shim under for safety but I haven't run shim under before so I'm not sure how often service intervals should be.
Gl with the engine, hope to see more videos in the future!
@@connorquayle5722 ... For Single Vanos, probably a little easier, as timing it up afterwards I would imagine to be a little simpler.
I think the 3.0 engines have 7mm valve stems, as opposed to 6mm, so would benefit more from the weight savings of shim-under-bucket. There are two things I would be mindful of when doing clearances though, firstly, if you are measuring clearances, and then using a micrometer to measure the existing shims and calculate a new shim thickness, I would make sure that you yourself also measure any ones you've had ground to go in, as you and the machine shop will apply different pressures to the micrometer, and hence get different readings.
The other thing to make sure you do, is go gingerly fitting the cam carrier caps, so that you don't damage any alignment dowels. Doing clearances isn't that bad a job, but definitely a pain when compared to a normal setup.
Next time make a video with some kind a music or something
No sound
well done great work as always.
Super Duper Cool
Well done Mike - perfectly documented. I enjoyed watching that!
👍
Beautiful!
This produce more horsepower than S52, right?
Hi Joshua, should be in the region of 360~370BHP I think.
@@mikeymike6017 says who? You need a lot to do to get 370 from a S50B32....
So you put 8-9k in that engine but you did not make a dyno run to SEE your results???????
@@buyankaratren9822 I understand your point of view, but the biggest power gains with one of these, is with a big airbox. I said '360-370', with the 360 figure being quite easy to hit. The rest is all incremental gains. The power expectations I have, are quite reasonable.
And as yet, the car remains 'un-dynoed', as two years ago I moved to Japan, and my two e36 Evo's are still in storage in the UK until shipping costs become effective for me to ship them out here.
@@mikeymike6017 nah it's not easy to hit 360. With this statment you're showing that you unterstand nothing about the S50B32. This engine is very difficult to build up. 80 % of the engines doesn't even hit their 321 BHP from factory. All of them are about 300 to 310 BHP.
If you wanna hit 350 or 360 you need cams, exhaust, airbox, Alpha/N mapping. And the engine must be 100%. Then in the end it's about a good mapping job. All done perfectly then you have at max 360. 370 is a dream. Please don't go in the internet pretending you are the man with the S50B32 engines.
@@mikeymike6017 and no excuse for not having a dyno run. This is the FIRST thing you do after a job like this. Telling the internet you moved to Japan.... who wanna know?????. The people wanna see the result after the job. Have time for trolling the people with a video but no time for dyno run. Must be a joke?!
AND NEXT TIME. DELETE THE VANOS in a Race Engine.
Is m3 v8?
no , its straight 6
That golf ball finish is so stupid behind the valves it will disrupt air flow
its actually better, it helps mix the fuel so its more consistent
Your right
@@Joefred77 helps with air fuel mixture on the vacuum, low air pressure side. Better mixture = better combustion = more horse power.
No, it's all proven on the flow bench of NG Motorsport. They build the highest quality parts and make heads for very much very fast cars on the drag strip etc. They know what they are talking about, trust me.
@@BastianKH who are to trust to? Come in to internet and say "trust me"....? Really? Just saw the web page of NG Motorsport. They "prove" it with some mickey mouse graphics....wooooow. So i will trust them. This is some high class bullshit.
Hi what grade oil do you use ! Cheers
Steve Smith Hi, I use Fuchs Pro Race S 10w-60.
Hi thanks for the reply , would this oil be ok for a standard evo engine cheers Steve
Steve Smith arguably not really. 15-40 or maybe 15-50 is better suited for a car that won’t be hitting track temps
Are you sure you have the correct engine sound track? It sounds like a 4 cylinder.
984francis lol nooo that’s because of the throttle bodies and no airbox.
