BMW V12 in Boxster S with Tiptronic Help! - 986 Forum - The Community for Porsche Boxster & Cayman Owners

alipendier · 08-01-2010, 08:53 AM

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 · 08-06-2010, 03:51 AM

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.

Boxtaboy · 08-06-2010, 04:54 AM

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.

I say if it is your car and you want to stretch it then go for it. It takes crazy ideas sometimes to develop new things so good for you for the effort.

What I don't understand is why stretch the passenger compartment if the point is to put a longer engine in it?

The Boxzilla approach would be much easier if the V12 was really the point.

If it was me I would keep the front of the engine where it is and simply extend the rear of the car to accomodate the new position of the rear wheels. Basically stretching the area in front of the rear wheel arches not the passenger compartment.

It will be interesting to see what it looks like when it is finished.

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?

Stroked & Blown · 08-06-2010, 06:24 AM

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.

Lobo1186 · 08-06-2010, 08:08 AM

also adding to what S & B said. you can also retain street legal status with the bowtie crate motor. unlike the V12 which will never EVER be street drivable. (legally)

Thanks Boxtaboy!

S & B Are you aware of anyone that has succesfully completed an LSX swap?

Lobo1186 · 08-07-2010, 09:28 AM

successful LSX swaps into porsches have been going on for awhile. the 911, and 928 and that whole line have many MANY examples even the 914.

now the boxster is something a little bit special in the fact no one has done this before. but currently a guy named Brad Roberts is in the process of developing it. according to him he has everything all set he just needs to get it started and rolling.

Now, his process has been a little bit slow because he is trying to develop the kit and not just make this a one-off. according to him he will have a running kit v8 boxster hopefully by the end of the summer.

there are a few threads floating around about this topic but due to some issues he has had with other people on the forums he doesnt like to come on much, and he has shut down his own boxster site.

here is the closed site that has information in contacting him

here is the 986forum thread on the v8 topic.

hope this helps you cause of frankenporsche

Simply horrifying!

alipendier · 08-06-2010, 03:19 PM

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...

Man, props to you for taking all the jokes in stride. Good luck with the conversion, and show us how it turns out.

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!

Lobo1186 · 08-10-2010, 10:06 AM

I wouldn't pay much attention to him. He has troll written all over him.

but, ill give you props for this project. it has long odds but will be gratifying if accomplished.

landrovered · 08-10-2010, 10:10 AM

BT has 22 posts as of this writing and only two or three are about boxsters, the rest are political. Take it with a grain of salts.

edevlin · 09-27-2010, 04:33 AM

I like it, remember this is supposed to be a fun pastime. They also used to say that the earth was flat.....

Well, let's see the finished product!
