BMW V12 in Boxster S with Tiptronic Help!

[JTP]

This is a cool idea, but you're going to take a great handling chassis that Porsche spent millions on R&D to develop and it is going to be ruined by cutting it in two and stretching it. Weight distribution and handling characteristics will all be severely affected, negatively. It would be a cool show piece when it's done. I wish you luck though.

Not clear on the purpose here. Anything can be done with enough time, inspiration and $$$. I assume this is going to be a stripped out race car that barely resembles a Boxster. Why use a Boxster chassis at all? I would think a purpose built tube frame designed around your powerplant would be simpler and a lot better in the long run.

** Porsche DME will be very unfriendly to the BMW motor.
** Boxster tub will be heavy and useless in a purpose built 700hp race car.
** A stretched frame Boxster will have few of the handling qualities of the original car.
** Tip transaxle will not survive your powerplant.

It might be cheaper to just buy a 997 cup car and go racing.

Thanks for all the info

I would still like to know if someone can tell what the max HP the tiptronic can handle, maybe that can clear a whole lot for me... Still

Arguably the silliest idea that I have yet seen here at the forum.

Tell me: How do you propose to do a "frame stretch" on the Box, since it is unibody?

[alipendier]

Silly is what silly does... The frame is already stretched! no proposals necessary here, its better to stick with what you know

That was just aweful to watch.

I wouldn't buy a car that had been stretched like that for a buck.

What a waste. Somewhere in Germany, an engineer weeps.

I bet it will handle really well now too.

Take a really well balanced sports car, stretch it, make it heavier by throwing in a big V12, and mate it to an automatic transmission. Sounds like a nice recipe for turning it into a cruiser. Oh well...as long as the guy enjoys it. Me? I would much prefer to just drop in a Porsche 3.6 or 3.8, and turn it into a super Boxster instead of a Boxster Limo.

very interesting. but does that really help in your situation? you would need the engine compartment stretched or at least cut into in order to fit that motor in and or different transaxle. which begs the question why this V12? is it because you have it on you and do not want to buy an engine?

I used to "experiment" on a frame of an old Jeep CJ-5 that I bought for $400. Bobbed, boxed, lowered spring perches, etc.
If this is a learning exercise, more power to you. Just be sure to have a pro check it out before you go driving it on public roads.
I hope you got a cheap boxster shell to experiment on, because you will probably need a second go at this. No offense intended, but based on the questions you're asking, it doesn't sound like you really know what you're getting into. Treat the first one as a learning exercise, then do it "right" on the second frame....or get the assistance of a pro who has done this type of thing before.

The stretch in that video was:
1. Stretching the floor, not the engine compartment - a simpler task
2. Ghetto

If you want a powerful engine conversion, do an LSX swap, as mentioned before. More power than the dated BMW V12 and no frame stretching needed.

Simply horrifying!

[alipendier]

I actually got the answer from some online searching, the video was just to show that it is possible to stretch the car, mine is actually stretched in the engine compartment. The build is on...

That was painful, like being forced to watch an autopsy performed on a beloved family member.

I appreciate your enthusiasm even when I don't understand it. Good luck with your project. Please post photos to the thread as your project moves along!
