    That is no problem. 10 years ago people were making 265 rwhp with 264/256 schricks.

    Correct European car made 264whp and 236wtq on an s50 with super sprint US spec headers, ss US spec mid pipes, SS or AA catback , off the shelf tune, and Evo sport under drive pulleys .

    It's doable.

    Volloso just tuned a Schrick car to that range on a low reading dyno in 100 weather. I watched it happen lol. It's definitely within the range of possibility.

    Also, I'm fairly certain that you can use the springs from an M50 non vanos head. From what I recall they are dual springs and are significantly stiffer than any other valve springs in the M5x/S5x family. I went supertech because my cams are even more aggressive, but I was seriously considering them for a while.

    Check out this thread. https://www.bimmerforums.com/forum/s...-vs-M52-vs-S52

    Also, fun tip: Google image search for 'M50 non vanos valve spring' will turn up some of the photos from that thread that are no longer visible thanks to photobucket.

    Well, need to order a rebuilt vanos from VAC, so I'll just get those OEM+ valve springs from them too.

    Yeah, me too! Only thing I'm bummed about is that this didn't happen at the end of my season so I'd have the time to rip it apart myself.

    You did not list a head gasket in the parts you have ordered. Did you check with your shop which brand head gasket they are going to use?

    Going with a cometic head gasket. Shop will choose the thickness to give adequate piston/valve clearance but allow a bump up in compression ratio

    I would skip the cometic but my experience is with thicker ones for forced induction. I don't think the very minimal, probably unnoticeable extra power from a thinner gasket is worth the reduced reliability of the gasket and of moving the valves closer to pistons with stock reliefs particularly when using a higher lift cam. For a built NA motor, I might consider pistons that add some CR if I ran on 93 octane.

    Hmm, good point. So which head gasket set should I get? OEM, Victor Reinz or Elring?

    My build has a Cometic headgasket and OEM headbolts, 11.5:1 compression forged pistons and is tuned/runs on 94 octane. I had no issues. But then my pistons have generous valve pockets.

    ^^^^^ This!!!!!! Elring most likely makes the OEM gasket for BMW. My M3 had 92k on it when I bought it, and at 102k the head gasket blew between 5 & 6. It was a Victor Reniz.

    Interestingly enough, the Victor Reinz gasket set is quite a bit more expensive than the Elring one.
