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.
