Yes my parts have arrived for project 300 HP

Center bearing, flex disk and new drive shaft. Yes.... next my cams, hd hydraulic lifters, headers. Then the ported intake, and a few other things that I have in mind. But project 300 HP is still going as planned.

What else are you planning for this goal? 300 whp? Or bhp? And by ported intake do you mean porting the head? Or a larger throttle body? You'll need more than cams and headers for 300whp. I'm praying for 215-230 crank hp...

Details

Chip
Exhaust headers
Bigger throttle body
Mass air flow meter
Fuel pressure regulator
Ported intake
Performance cams
4.1 differential
Lighter flywheel.
740 front 540 rear brakes.

I'm still doing research on what cams to use
But the actual HP should in theroy be 284.5 without a super charger.
Take note that I'm working from the bottom of the list first and I'm too the cams. And I welcome helpful advice on what works and sources for parts.

Feel free to read my sticky on the cams. S52 cams require the cam trays but are more common, same performance as S50 cams.
Turner Motorsports makes a kit that includes S50 cams in a kit ~$800 (Cha-friggen-Ching) or if you're paying that much, you could go for schricks. The chip will be interesting because of all the mods, you may need a custom one written or let the DME do it's best to adapt.
I noticed Beisan VANOS rebuild kit not on your list. Please revise it to include this. It's $85 (shipped) and if you're going into the head then this is an absolute must, simply a requirement for a well-running motor, especially as old as ours. Look forward to this build.

You are correct sir. 91 525 M50 = non-vanas. I'm envious of your project. However, I'm skeptical that you will get the HP numbers you seek, but am hopeful you will.

Thanks man, I'm hoping that I will too. Looking in to 95s cam posting now. Not really sure as to where the info is on if the s50 kit is what I need.

Didn't realize you were a 91, I retract my VANOS bit. Let me get the link to the kit. I'll be back with an edit

Ok so I'm having slot of trouble finding the kit but they can give you s50 cams for $1,500 or schricks equivalents for $1,200. Pick your poison.
Best bet is to search eBay or forums. Somebody parting out their m3 would be a solid bet.

740 and 540 brakes are the same. Figure I'd share to help cut a step for you. They both use 302 x 28 rotors and calipers along with rotors are the same part numbers.

1995 is the only S50. That you'd just need cams.
1996-(whenever the E36 stopped) is the S52. You'd need both cams and cam trays.

I have a bunch of feelers out there with my connections, its never a one-stop-shop, so you may need to get an exhaust cam and then an intake cam, and then the trays if you get the S52s. People parting their cars usually sell the motor as a whole, and if the part the motor then the cams are one of the first bits to go. You must stay vigilant all the time. I found my cams on E90 post, less than 1 day after he listed them, i was also willing to pay whatever he was asking and enough buffer to not be outbid. I'm looking at my prize now

How about the s54 engine? i.e the e46 m3. Can those cams be swopped into an m50 motor? If so, any idea about lifts and durations? Thank you padre.

S54 won't work. Double VANOS.

Also now that I think about it, s50 or s52 cams may not work on his non-VANOS motor...

Where do I cross reference the cams and lift that I would need. I was told that the m5 cams might work. I need some sort of chart. To cross ref the whole thing so I can get my feelers on that.

Well what about if he attached a double vanos unit to his head? Would the s54 cams work then? What do you feel?

I think the person who told you that only thinks that because it's a 5 series, In reality, we have much more in common with the 3 series. I'm goingto assume you mean the S38 motor. I haven't heard anything on whether theyll fit or not which I believe is partially contributed to how rare they are.

I don't think so. The S54 cams don't work in my friends M54 (2005 525i). I don't remember the reason why but I think it had to do with differences between heads because the M3 has ITBs.
Your best bet for 300hp is going to be a sh!tload of mulah. Do a VANOS conversion. You need a specialty opinion on this, I only know of one member who is doing this, he can PM you. Do an M50 motor swap, you can get them cheap, also you can build it outside of the car, and it makes your clutch and fly installation a breeze when the whole motor is out.
Rebuild the VANOS, do S52 cams and tray, get pink-top injectors, ask dblias to make your car a set of ITBs, get forged rods an pistons in a stroker kit for 2.8-3.0L.



You'll hit 300whp.

All M50's have a timing chain regardless of vanos.

dont necessarily need to be forged bit, but if your going to do internals, why not?
The cam trays are only necessary if you get E36 M3 cams after 1996. The 1995 dont need the trays.
You'll also need a chip and a vanos unit. You know how much this is going to cost right? why not go buy a used E46 M3?

ad, could you document your work?

Even a crappy cell phone pic on what you are doing could save an idiot like me days of surfing the net, lol.
If its not too much trouble, snap a pic or two with descriptions of what and why.

Thanks, and good luck!

I'm with you Steve, skeptical about the hp numbers. He's got to increase his liters and that means bigger bore and longer stroke.
He will certainly increase his numbers though.
