So what is the adapter plate going to run? Found a decent deal on a 99 Boxter tranny. It is complete from the shifter back. While I do plan on doing a suby conversion. It would be of more use in my v8 conversion that is almost road worthy. I do want to know for my suby though
Just wish there was an option for the boxter tranny with my v8. I need to look into it more I guess
. Probably is an option out there somewhere
I wouldn't put a V8 in front of the 5 speed Boxster tranny, only the 6 speed. If you are going to use a V8, the only real choice is an LSx motor. For that application, KEP will make you an adapter kit for around $2000 last time I checked and from what they told me, it's something like 4" thick
There have been other people who were supposedly working on another LSx/Boxster based conversion kit, but to my knowledge, it hasn't actually happened yet. I know there was a shop in TX I think that was advertising a conversion kit for the LSx too but I've never seen a finished product. Ultima is offering an inverted 996 gearbox (same as Boxster 6 speed) so that means they have done it, but it would require running an inverted rear engine box.
If you want to use the 5 speed, the Subie motor would be ideal as it doesn't make the kind of gearbox killing torque that the V8's make. Although people use 901's in their V8 cars so I guess it's possible.
I'm not going to be talking "prices" on here because I'm not a paid vendor and it wouldn't be fair.
