BoxsterLS376 introduction - LS3 conversion :)

The knuckle are a lot different due to the achitecture of the 996 rear suspensions.
I'm sure you can find ones for less than what the 1st company quoted you
Good luck !

Just thinking aloud here, but I wonder the effort involved in swapping to a 996 turbo rear hub. I ass-u-me that the bolt pattern to the trans is still 120mm, so all you really need to do is get that axle though the bearing... which typically requires machining out the hub for the larger outer diameter, or just swapping the whole knuckle.

I've never seen a 996 rear hub or knuckle, so I have no idea how far into left field this is is...

I thought about going down this route, but to be honest the though of acquiring the parts alone turned me off due to cost, it all adds up really quick.

I am talking with another company who has a great reputation, if they come up with a good price then i'll go with them, otherwise I'm going to piece a set together myself using Porsche 930 CV parts. Lots of stuff readily available out there as they use the 930 transmission in a lot of off road and dune buggy applications.

Yup it would require quite a bit of work and added expense which is what I'm trying to avoid! Hopefully this company I'm talking with can come up with a reasonable setup.

How much is reasonable you ask? Well that all depends of course! To build them right with what I would call "the good stuff", I think If I can get them done for $2500 or just under.
It all depends on the parts you use though, I know I can build them for less and probably save $500 or so, but how long will they last?

Nice thing is if I build them then I can rebuild them easily enough and then I could upgrade whatever fails later.

Either way I'm kinda broke right now so we will see, hopefully my ebay stuff starts selling! Anyone need a 3.6 Liter 911 engine?!?!?!

Crazy idea, maybe the front carriers from a 996 TT? Since the base boxster uses the same carriers front and back and S uses the same style but beefier in the back, maybe that could work?

Yeah thats kinda getting back to the more effort then it is worth category, plus parts etc. definitely would not end up cheaper~


So regarding the axles it looks like the best solution is going to be to make a custom set using 930 CV joint setup. They are commonly used in off road conversion and high HP applications. Many different parts available but it could be done for as little as about $1,600... That includes custom stub ends, "high performance" 930 CV joints,bolts pre-drilled for safety wire, flanges & boots and would use a chromoly axle shaft.

Me, I'm a do it once kinda guy so if I were to do it i'd prefer to use all the high end stuff. This of course bumps the price up quite a bit by about $1000~, biggest differences being upgraded CV joints and stronger axles.

Either way, for right now given my current budget for I think the best thing to do is just not drag race it with first gear launches Just gonna leave the inexpensive axles in for now~

Greetings everyone,

So I finally decided to strap the mufflers back onto the V8 car and made a final video here to compare the 2 systems. It takes less then an hour to swap them out once you know what you are doing, although i'd love to build a valved system for it one day, this will have to do for now!

The sound is a bit harsh from the bumper cam but you get the idea. The car is so much more civilized with the mufflers and i'm sure my neighbors appreciate it

It still has that great v8 sound but for the unknowing they will probably think the ol' Boxster has got a misfire going on or something.

Anyway I made a video with a little bit of straight pipe vs. mufflers comparison, hope you enjoy it! Still uploading till about 11PM EST so give it a few more minutes and the link should be working~
