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. |

To your point, it's about budget. I have an LS3 and I didn't want to worry about things breaking so I went with a Boxster S 6-speed (G86-20) as they've been proven to about 500 hp.
They can be found on ebay in the $2k range. You can get a stock shifter and cables for a couple hundred, last I looked. Kennedy Engineering makes the adapter plate, flywheel and clutch. Or you can get the whole kit, including trans mounts from Renegade, but it's not cheap. Best of luck with your decision. |

Curious as the later 981 GT4 6MT signed off on by Motorsport was limited to 310 lb-ft, which arrives at 4700+ rpm in that car. The gearing is pretty bad in a 981, too, with 2nd stretching to 84 mph and 3rd to 112 mph—so not too fun on a back road. I've started to wonder about taking a 7MT from a 991 and flipping the ring gear as people do with 915 gearboxes, as the torque limit is higher. Next question is whether there's a way to delete 7th gear or lock it out like Porsche does on the GT4 Clubsport PDK, or just enjoy 9,000,000 miles per gallon. |
