A lot of older threads on the topic of marrying transaxles to V8s. I just finished rebuilding an LS1 and am looking to weigh current and cost effective options on the trans. G50s are out of my league but Boxter and Subaru variants sound efficient and reliable. Currently running a SBC 350 and 901 side shift.

For those of you who have had the experience of building them, or are building them now, what are your opinions, preferences, or realizations?

Planning for a street/track set up. Thank you for the help in advance.

Axles will depend on what you do at the hub. If you stay with 914 stub axles, you can get axles with Boxster inner CVs/914 outer. Renegade sells them, as do others, I assume.

With the LS, I wanted as strong a set up as possible so I went with late Carrera hubs and 911 e-brake set up. I run standard late Carrera axles, as pictured. To work with the Boxster S trans, you need a 1/2" spacer between the inner CV and output shaft (make one or you can pruchase from Renegade), and accordingly longer inner CV bolts. There is also a spacer that goes over the splined end of the axle (available from Patrick Motorsports).

NOTE: since the "stub axle" no longer lives with the trailing arm (when the axle isn't in the car), you aren't supposed to put weight on the trailing arm bearings without the axles installed. (not necessarily torqued, but they should be in there to roll the car around, etc.)
This makes it a bit of a pain to work on things when the trans is out, since you have to leave the axles installed and supported.
