PPG Sequential

[mrpav]

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.

What are the horror stories out of interest?

 

Thanks

Got one in my car, I didn’t get to drive it much before I pulled the engine out but when I did I loved it and the mrs even preferred it over the getrag

[Piggaz]

No issues so far.

Piggaz, What sort of power are you pushing at the wheels?

517 awkw.

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 totally agree and this was my beef with them when they first released the sequential. I spent many hours on the phone with PPG when I was originally going to go down the 5 speed dog box path and they said themselves the issue is with the 5 speed box IS the housing.... then they make a sequential out of the 5 speed box. WTF?

Got the OS88 in the car and removed it after 300 kms. Didn’t like it. At the time (mid 2017) I don’t think the samsonas box was a thing yet so it was the PPG, OS88, Holinger, Albins that you needed to take a grinder to the car or back to a 5 speed which is just NOT an option.

IF I was doing it today, I think the Samsonas box would be the pick. Suck up the scaffolding gear lever (surely they can do better here) and cop the noise on the chin. With cranky diffs, pumps and whatever else is going on, what’s a bit of extra “character”?

It looks like PPG have released a billet housing now. Unsure if it’s any bigger or it’s just shinier.

I have had NO problems with the PPG box, it’s been great. Put all the trim around the shifter and it’s pretty damn quiet, shifts well, no oil spewing out the gear case or any other dumb problems.

An issue is with these types of boxes (sequentials in general) that guys want to run 1500 whp through them and then wonder why they break. If you run a reasonable amount of power through them <600 Wkw (I use the term reasonable loosely here because 600 wkw is a crazy amount of power) there shouldn’t be any issues.

[r32-25t]

My reason for going to ppg was the fact I’m not going to make 1000 plus horsepower with my car I don’t need one that’s rated for 1,500 and it comes as a complete package ready to bolt in with the position display, gear position sensor, strain gauge (load cell) 

also primarily being a street car I didn’t want straight cut gears and as Paul said once you put all the rubber boots back in it’s pretty quiet and every report i had heard say how easy it is to drive and they aren’t wrong 

and being an Aussie product if I do break it i shouldn’t have to wait 6 months to have it repaired or even wait almost a year to get the box only to find out half the parts aren’t there like the poor guy in the build thread 

is it the best gtr sequential on the market? I highly doubt it, it was the one that best suited my needs in a sequential 

[BK]

Great responses there guys 👍. I'm sure this is exactly the sort of information and feedback that anyone in the market for a sequential is looking for and is much appreciated.

[GTSBoy]

And also to moderate/mediate the various threads started with "I wanna get a seq box and woz thinkin ppg but the horror storiez bro".

[GTSBoy]

No offence intended to the OP, by the way.

[Piggaz]

Guys have to so be a bit realistic about what they expect their equipment to hold. The GTR scene has gone farken loopy with all this “1200 whp GTR street driven, does high 8’s” rubbish. 

Between YouTube, Instagram or any other “look at me” social media dribble, everyone wants to be a super star and out donkey swing the next guy.

A 600 kw GTR is ridiculously fast (mid 9 seconds or whatever) and if built right can stop, turn AND go. Anything faster that than really becomes a 1 trick pony. To have a manually shifted 900 kw GTR with sticky tyres, on a prepped track launching at god knows what RPM in a heavy car, is it any wonder why the drive lines fail? There is no give and all that grunt/shock load has to go somewhere.

Come back down to earth!

*off topic rant 🤪

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.

Probably overheats if you street drive it to the CBD and back too

Thermo fans dis dat, no shroud.

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.

The outright failures are more like what Paul was saying, when people shove 1200rwhp + through them and wonder why it broke.

I say go on get one

You and Paul are a "HORSEPOWERISTS". When I get 1200rwhp I'll wonder why it broke and I don't want to hear shit from either of you @freehorsepower

Next task will be trying to tune the flat shift without having to harsh a gear cut. 
 

Thanks guys.

That's easy with DBW and torque management.
