915 Rebuild

DORIGTT · #1 April 26th 2006, 17:04

Once you're done, you WILL let us know if that dreaded shift/grunch is gone and that once and for all that the 915 gearbox is not the bane of conversion existance right?!?!

I really don't want to spend the extra dosh for the G50 as long as I can get some smooth shifting (I'm not drag racing, just autocross/time trials and open track events) reliability and power-handling capabilities.

Keep up the good work!

The 915 just doesn't like to be shifted quickly.. I had mine fully rebuilt too. All down to Porsche's design of synchro.

Nice job Wally, I helped with the rebuild on mine and I still don't think I would tackle it on my own!

For that purpose, it would be excellent. Russel does dragrace with a 915 in his 450 hp IRS bug, so even that would be no problem.

Personally I think with all the right bushings in your shift-rod couplings and the factory short shift kit, these boxes can be made to shift very quickly. At least quickly enough for my taste/purpose I'am sure.
Ever asked about any G50 parts prices?

I choose this 915 tranny very carefully (weight, CV-size, gearing, cost) and after much thought about the subject

I will put a lot of new parts in it, but not everything ($$). Also because I'am not sure if it would make a noticeble difference if all wear parts would be new.

Thanks for the moral support; i will probably be needing it when I put everything back 'in umgekehrter Reihefolge'

This is what it looks like when you go parts hunting in 'the right place'

"What the heck is that? Hey, its got Posche wheels, but it doesn't look like a P....."

Thats one nice shop (the cars are not bad either

). I think that non- porsche is a VW 412. Those came with type IV motors!
