Recently blew up the bottom end on my S52. I lost 1 piston, 3 rods, the crank and the block. Machine shop has confirmed the head is good (no cracks or bends). Not sure if I’m going S54 or partout, but I can’t afford a rebuild or a swap so I’ll be selling what I’ve got as a start. Prices listed do not include shipping or paypal fees, I’m fairly firm on them but willing to take reasonable offers. I’m located in Orange County, CA but am willing to ship parts. For obvious reasons, I’d like to keep certain things together, but again, make an offer worst I can say is no. The cams have 7k miles, all other head parts have 18k, they’ve been through 3 autocrosses and 1 track day earlier this year (my first). The rest are street miles. Pics will be posted later/can be provided upon request.
Built S52 head– Ported & polished exhaust ports and all 24 bowls/combustion chambers (intake ports left alone for safety), Supertech dual valve springs, seats, & steel retainers, new lifters, VAC 286/272 cams. It will need 4 new exhaust valves and 2 new intake valves. Currently at the machine shop, no work has been performed, just the check. All in this head cost me about $3500 to build. I’d like to get $2500 for it as it sits. I can get it prepped to drop on immediately but that will be at whatever my cost is.
Rebuilt, anti-rattle & limited VANOS (7k miles) – after some trial & error I eventually got to a 4.8mm shim which is what worked with my motor. I also have 2, 3, & 4mm shims I can include for you to test and run what works best for yourself – VAC wants $370 for a rebuilt, limited VANOS, I’ll take $200 (I can de-limit it for you for an additional $50)
VANOS Solenoid & Control Piston – I replaced these 7k miles ago with BMW parts. Happy to include/leave installed with the VANOS, but given the newness and the expense it will be additional - $250
22RPD tune – Ideally and for obvious reasons I’d like to keep this together with the VANOS and the head/cams. This is a dyno tune, not a canned tune and they did a good job of getting the most out of the car with this. 900 rpm idle, 7300 rpm redline (extra rpm used only for autox), no SAP, no rear o2’s, no EWS, and no fuel wasting burble. The car made appx. 290whp with a 130k mile, stock bottom end after a couple hours of tuning. Idles beautifully (with a good bit of lope), and even runs A/C like a champ. This tune picked up 15whp and solid torque across the board over my previous Epic tune. $250
If you want to take all of the above as a package deal, I’ll do it for $3000 which will save you $200. You can drop this on a stock bottom end and run with the big dogs. Or build up a nice bottom end and slaughter the big dogs.

- DNA Motoring headers & exhaust. Can provide clips, honestly sounded incredible, I got a lot of compliments but the rest was also far from stock. That said, my car was a test mule for this and they welded one of the headers to the y-pipe to make it fit. No idea why. It really should be separated before install, and I can get that done at an extra cost. $500 (includes headers, y-pipe, resonator section & catback)

PM sent for M50 manifold and exhaust
Cams, will you sell separate? What are they lift/duration and manufacture?
My apologies to all interested parties for the long delay. I had some medical and personal issues that made this part out take a back seat. I'll be much more responsive going forward. All PM's have been replied and the initial post has been updated with what has sold.
S52 ARP head studs added to the for sale list.
Replied!
Replied!
Don't really want to part just the cams yet and if I do there is one person that asked before you. In any case, they're VAC IP Dominator cams - 286/272. All the relevant info can be found on their site.

M50 manifold sold locally a couple weeks back. I'm on vacation until Friday so getting pics and whatnot has to wait beyond what I've already got. All you race/track guys, I know the season is ending if not over depending on where you are. Grab this now and make a kick ass setup for next year! Can provide links to videos (street, track, & autox to anyone curious about what it can do.I know we spoke in PM after this but for the sake of sharing info. Ported & polished all combustion chambers/bowls and exhaust ports. All intake ports left alone for safety due to the thin walls with coolant passages behind them on that side. Supertech valve springs with steel retainers for longevity vs. the titanium ones. Yes, you and a few others. Sounds cool man, hope that works out nice for you!
