There's been a bigger delay....... I fitted oil restrictor while there and on the way to dyno it developed a big tick, found A1 and A2 cam caps have melted FML!!! due to no oil to them, I suspect that when the restrictor went in it created a burr that blocked the gallery to them 2.

Good news is i have the S50b30 cam carriers still, so im thinking its going to be another long night!! Bad news is i grew fond of the B32 rocker cover as the B30 one just doesnt quite have the same look about it.

Ok so I frickin should have seen this coming... upon further inspection I found the insert side for the restrictor on the intake side of the b30 carrier... now the b32 carrier has it on the exhaust side. 

This means on the b32 the oil galleries won't line up unless you put it in backwards and you can't do that because of the way the piece is made with the thread on one side only, which leads me to believe the b32 never had an issue with flooding the head of oil.

They must had revised the head design, and looking at the two trays side by side you can clearly see there is a lot more drain holes and in turn does not need this restrictor. FML

So learn from my mistake I feel like an ass, don't believe everything you read online and definitely do not put a restrictor in a s50b32 

 

So¬†next question is who has a good b32 cam carrier they can sell me??? ūüėĀ

You can't mix and match cam caps, pull the carrier and get it re tunneled

So you reckon we can rebuild it?!

yep cant see a issue to do it, just use what caps you have and they can re tunnel to correct aliment clearances and youll be like new.

keep all caps in the order they came off if you can if not the engine shop will sort but pretty sure each one will be numbered

The only place I can think of would be Taylor Automotive up in Auckland.

A little update, still on the hunt for a carrier.....

In the meantime received the remainder of my throttle body adapters :D thanks to Jethro @ RML engineering..

Got some stainless rivnuts to secure things around my car instead of the alloy ones which tend to not work to well, and its a nice weekend by the looks of things so might get some more things done!

Little update, Super stoked we just had a baby boy (Keaton) so been spending most of my time with him, puts everything into prospective... So ive ordered a brand new s50b32 control housing (11121403686) from BMW to get things done :D will update when it arrives

Yeah we doing alright, no one ever tells you how hard it is and if they do you never believe them, it doesn’t help my boy has cystic fibrosis and the more severe one.. really hit home, looks like there’s a long journey ahead....

On another note I got a aeromotive fuel regulator and gauge from Paul at NZ Performance and installed it the other day it makes it real easy when the factory fuel reg is seperate from the rail.

Found out when installing s50 cams with vanos delete you cannot use timing tools as it will be way out and it was, I installed the new carrier and set up the timing, I left the intake cam at .4 and set the exhaust at half the factory lift at tdc to .75 using a dti gauge and the b32 specs from cat cams, after that it ran a lot nicer..

I couldn’t help myself so I set up the link g4 and done some runs with the data logger and edited a few fuel cells, I would almost say it goes just as hard as my old engine even with a poor tune.

Sorry to hear of your personal issues i really hope all turns out well and im sure it will mate.

On other note regarding your cams the best thing to do is find the full cam specs and mainly the center lines and dial them in using that method, and fast and more accurate, find TDC with a dead stop then rest is straight forward.

Did the same when dumping the stupid VANOS off the V10, but i used a Cam Doctor on the cams to give me exact numbers thank fully i have 60 Deg in and 30 Deg ex of crank rotation so plenty to play with on the dyno, safe setting for you would be 108in and 115ex as a starting point being turbo.

Thanks mate, I like to think everything happens for a reason.. we love him to bits and wouldn’t change a thing...

I figured that the most important thing is when the exhaust closes on a Turbo and when the intake opens and everything else will just fall into place. If I didn’t have the specs of the overlap I would have done what you suggested..

http://www.catcams.com/products/camshafts/datasheet.aspx?ENGINE_id=103&CAMSETUP_id=222

see where it says valve lift at tdc... I suspect that is the overlap

So being Turbo I wanted the exhaust to close a little sooner in case there is back pressure issues in the exhaust manifold.. from what I read the intake cam is where the power is moved in the rpm range

this is all new to me and very interesting let me know if I’m wrong..

Hey me and a friend are building a cheap hack car for shits using bits and pieces lying around, does anyone know if the s50b30 camshaft fit into a m50b25tu single vanos?

 

Nevermind found my answer here https://www.bimmerforums.com/forum/showthread.php?1626914-S50B32-cams-into-an-M50

 

going to try make this car look somewhat like a German police car

Alright so got the car back from the tuners, told them to tune for low boost first of 12psi, and pretty much what i thought it made the same power 460whp but was a little later in the rev range than what i would have liked, he gave me a big list of things i need to do before upping the psi to above 20psi which from memory is larger radiator, re plumbing the turbo and waste gate cooler lines, moving the charge pipe work away from the exhaust manifold and waste gates to reduce intake temps. All minor stuff and im sure there was some other stuff on the list

Also just arrived is the other 3 dunlop 265/310/17 racing slicks to complete the set which will be fitted up the the vehicle soon

The big fancy clutch set up i got slipped on me a little bit with a full boost 3th gear clutch kick while driving so that will need to come out and be replaced, so the set up cost me around $1,400, this set up would be perfect for an N/A car and should still be in very good condition if someone would like to purchase it :)...  I will have to be getting something a bit bigger to handle the power.

 

On another note our twin super charged m43 engine'd German police car has now got excessive blowby on the rings so swapped out the engine for an M50B25tu engine and fitted a manual gearbox, decided to use this for a drift missile car...
