    • PPM Australia taking the BMW S85 V10 to 6.3 liters with $68,000 stroker motor

      PPM (Pure Performance Motorsport) Australia makes a lot of bold claims. Their stroker claims in particular are interesting as they say they have stroker motors for almost anything from Ferrari, to BMW, to Porsche, to you name it.


      Unfortunately, BimmerBoost has yet to see successful results with their stroker motors or even built motors at factory displacement.

      DME Tuning's built S63TU V8 from PPM lasted 15 minutes. That should make one apprehensive before ordering their 5.0 liter S63TU V8 stroker motor, right?

      A 6.3 liter S85 V10 is huge. The increase in displacement is 1.3 liters over stock. They do not name the bore and stroke combination that is getting them there which is a bit of a red flag. They simply state the bore is 94mm.

      Well, that would mean the stroke would need to be 91mm which most engine builders deem impossible with the S65 V8 or S85 V10.

      How is PPM doing this? Who knows if they even are. It sure would be something special to see a 6.3 liter S85 V10.

      PPM Racing Australia has designed an Ultimate 6.3L Stroker version of BMW S85 V10 engine.

        Do they even warrant their engines? I mean for 60,000$+ I'd rather have more than a warranty lol.

        Didn't see anything about a warranty but there isn't even any proof this engine exists.

        PPM are hopless. they cant even make parts to the correct size and within acceptible tolerances yet they try and upsell all this fancy super fine finishing and coatings stuff when they fundamentals are wrong. same the materials they use are good but they probably screw up all the heat treats and dont know how to machine them properly etc

        We had a few engines built here in oz using their parts and there is absolutely no tolerance/fitment or quality issues.

        I run the PPM rods and pistons in my engine, they where checked by my engine builder and he said they where the best his seen and measured within some ridiculous tolerance.

        I've had absolutely no issues and make crazy power on stock head and cams.

        We are just about to put together another full Monty engine including one of their billet crankshafts for the n54 with a single piece crank hub.

        The engine builder checked all the parts and he says they are absolutely perfect and has started the build.

        I don't know what happened with the s63tu but I don't know any engine builder that never had failure on a build, they all have in one way or another but its how they handle the failure is what's sets them apart.

        They have stroker kits for Ferrari's, GT3's, BMW M's, etc., and yet you never see successfull running example of these engines...

        Their stuff is junk. Even junkier is their support.

        We have no problems with any of their stuff on any of our n54 builds.
