    PPG Sequential

    in Drivetrain and transmission

    What I can't get my head around with the PPG sequential is the fact that they went ahead and used a design that fits the standard case. This completely turned me off after getting my quote from them for $23.5k assembled in a standard housing which I would supply.

    Going to a custom housing like a Holinger, Albins or Samsonas allows them to move the main and counter shafts outwards away from each other, increasing gear diameter, therefore more material and increasing gear strength - if you are comparing between the same gear materials of course.

    The OS88 did this to increase strength, but are obviously made out of inferior materials in their gears compared to the sequentials mentioned, or else every OS88 you come across wouldn't have been recently rebuilt or in need if a rebuild.

    @Piggaz@r32-25t So Paul, Brett and anyone else with a PPG sequential, with the above mentioned do you honestly think the PPG is even close to the same league strength wise as the 3 sequential transmissions I mentioned ? What made you guys want to get one ? Don't get me wrong, I think Pfitzner is a fantastic company and have a fantastic product - but they still don't have a deep professional competition motorsport proven use like Albins or Holinger in racing.

    Genuinely and honestly, not because you own one, but what do you think objectively their long term reliability is in comparison ? Do you think it really is the best sequential for a GTR on the market ?

    Genuinely asking, I'm not having a go at anyone's choice of transmission.

    I don’t think their problem is gear strength, it seems from multiple workshops and gearbox reconditioners I’ve talked to that it’s oem bearing failure due to the stock case...they don’t shit a gear within reasonable hp limitation. 
    Apparently they’ve changed their bearings now or have some sort of work around. 
     

    I think I’m going to pull the trigger on the dog and do it. Sam at neat seemed fairly knowledgeable so cross fingers I guess. Plus I‘ll only be around the 500 mark somewhere.

    From what I’ve gathered the main issues were with the oem bearings that were used inside the factory casing. 
    They have made some adjustments now and supposedly isn’t an issue anymore, jem’s r34 had a bearing upgrade for example.

    Hey guys, was about to pull the trigger on one of these for my GTR but more and more horror stories are appearing. 
    The first few revisions had a lot of issues apparently but some reputable gearbox shops have assured me they are good gear (esp when purchased outside of ppg)

    Other than who I’ve spoken to just looking for any other direct reviews of them from owners.
