Help Me before I F*** up please S50us Q

The M50 cam trays need the M50 hydraulic lifters. As was already mentioned, the M50 has 35mm lifters and the S50/M52/S52 have 33mm lifters. You can use the M50 trays and M50 lifters with S50 cams if you want. No, the S50 cam trays are NOT the same as the M50 cam trays. They are, according to RealOEM.com, a different part number.

You can use the S50 trays with the M50 cams if you wanted to as well, but you would have to use the S50 lifters too.

Do a Google search on S50 springs/retainers failing and then thank your lucky stars you haven't had a retainer failure yet.

Oh, and by the way, I have a full set of S52 springs/seats/retainers (fully matched set) for cheap if you want 'em. They've been sitting around collecting dust for 4-5 years now and I'll never use them.

The heads are virtually identical so you are good there. The main differences between an M50 and S50 are the cams, springs, and the displacement. Keep in mind that there are two different diameter lifters in the 24V motors.

With that said, you can mix and match at will basically. Just keep in mind that the dual S50 springs are meant for more revs than the single M50 springs.

I have a full set of S50 cams, springs, trays, and lifters that I will most likely get rid of this winter if you can wait that long.

i think you should buy a complete running engine. From past experiences i can almost guarantee it will cost you loads more to do it this way.

Well, it makes sense at first but most S motors are high mileage and sooner or later need a overhaul right? Whats the usual miles out of it if not over revd 250k? beaten on?

Sometimes the deep end is deeper than you think...

Yeah...already broke wanted a fully refreshed engine.

Again, M50 cams aren't the solution. Post a WTB thread in the WTB section and somebody should have some S50 cams. You can also use S52 cams if you use the S52 and M52 trays.

Did my research thanks

No offense, but it seems you need to do a lot more research and learning before taking on this project. M50 cams are beyond pointless in a S50 swap. Also you'd have to pay for a custom tune for your new bastard engine.

I really think you should have just bought a S50 because theres a lot you don't seem to know. I know we all have to start some where but it seems you might have bitten off a little more than you can chew. Also yes you can use M50 tray with S50 cams. In fact I believe the S50 and M50 trays are the same part number).

It was a good deal. I just wanted m50 cams to get it running then later get aftermarket cams, I havent driven the car in a while.
Guess ill stick to PN for advice. Thanks.

M50 cams on a S50? I mean yes it's possible, but I don't know why you would. At that point I'd just sell of the S50 stuff and do a regular M50

Well they are more hard to find. If I did S50 cams could I use M50 trays to Save some $?

Thanks

You'll be fine using M50 springs. The S50 is just a stroker M50 anyways so all the parts are capable. I also highly doubt there will be any real performance difference between the springs.

okay thanks! Could I use M50 cams though?
