what's the difference between S65 and P65 race engine.

The exact question is 'what makes the difference in performance between S65 and P65 race engine?' I wonder what the mechanical difference is.

See the last few pages of this thread for info on the P65.

BMW S65-based Racing Engines You've Probably Never Heard Of https://www.m3post.com/forums/showthread.php?t=1065981

Also greeneggs build your own flat plane goes into an extreme amount of detail. What more are you looking for? (Besides the money to buy the P65 Turner is selling?)

I already read the thread about S65 race engine. There are so many numbers like h/p, bore, stroke, cc and etc. Are these enough for you to understand the difference? what is the material of crankshaft, rods and pistons? injector size? drysump capacity? map or maf sensor type? camshaft spec? overhaul time or mileage? etc....The price of BMW genuine P65 engine is about 7000~9000euro. What makes such an expensive price?
I wonder a lot. And I'm seriously considering to upgrade engine performance on my track only m3 with reliability. because my engine is now the third.

If you can get a P65 for 9000 euro, go for it. Turner is asking for $25,000 here in the States. It does have a dry sump system, but that should not be an issue on a track car. Note that price is similar to a Dinan Stroker.

As for the the specifics, I have not seen information on those.

9000 is what you had posted!

I would suggest contacting Turner to get the specifics you are looking for. I'm sure there would be additional costs (tune, dry sump system, etc). You can also go the route of building your own as is detailed in greeneggs thread. Sounds like the more people who sign up the lower the cost.

I know. my mistake, 9000. If 9000, I'll send one to you. hahaha.
Thanks for your advice.

The p65b44 Turner has for sale isn't a flat plane crank engine like green eggs is building. It's a motor built by BMW Motorsport for racing.
It's a dry sump, forged pistons/internals etc
Special alloy lightweight motor that uses a different ECU then a s65. If you were considering it for your car engine management would be your biggest hurdle.



Just listen to it.. sounds so good

The look of the dudes face in the pits is great 😂.. he knows how badass that thing is..

Quote:
rods and pistons?
Your choices are whatever connecting rods and pistons you have custom made. We used Carrillo rods and CP or Mahle pistons.

Quote:
Injector size?
Stock injectors are good enough.

Quote:
drysump capacity?
Dry sump is made by Daly. Since a dry sump has an external tank which is custom fabricated to your car, capacity is whatever you make it.

Quote:
map or maf sensor type?
That depends on what ECU you use. You can use the MSS60 or one of many different standalone ECU's. If you use MSS60, it's whatever that uses. If you use a standalone ECU, it's whatever you want it to be.


Quote:
camshaft spec?
Those are posted in our "build your own p65" thread. 12.6mm lift, 292 degrees duration. Opening and closing are different than Schrick 292 cams. Bert has these specs.

Quote:
overhaul time or mileage? etc....
The P65 will vibrate more than S65. Expect longevity to be less. But expect fun to be much more.

The actual P65 block is Nikasil, not Alusil. The block alone is about $25000 Euro. Add a $10k dry sump pump and hoses. Add all the other internal parts @ $20000, Add the custom fabrication of the dry sump pump: $5000. Add a standalone ECU (Motec) @ $20000. Add labor to build @ $150/hour = $15000. Total here: $95000.

Compare that to our build-your-own project at about 1/4-1/3 the price.

We'll be happy to talk to you about building your own P65. If you're in CA, then you can come meet Bert and see his project in person.
