Thoughts? Cayenne V8 in a Boxster?

I have done something like 12 V8 conversions in 914's. I'm thinking about taking on a Boxster conversion using a Cayenne V8.

What do you think?

You cant hurt my feelings. It would still be Porsche powered (unlike the 914's I have built with SBC's in them)

Thoughts?

I doubt anyone here would tell you they think it's a bad idea... more power in our cars? Of course you should try it!

The question for me is, "Will that big thing fit in the small space provided in a boxster?"

Price wise and time wise doesnt it make more sense to supercharge the car? I'm sure that will take up about half the funds and time to do and it would be just as fast ,if not faster then the Chayenne V8.Just my two cents.

I guess calling it the Coxster would be insensitive and innappropriate?

Cayenne V8's are for pussies.

This is a conversion motor, baby.

Twin turbo V20, 3500hp and 13,000 ft/lbs of torque.



Better get some GOOD brakes and sticky tires.

Interesting concept, though.

My interest is totally peaked. Please keep this going. I certainly want to know if a kit can be made to swap-out the F-6 for a Porsche/Audi twin turbo 6 or a Porsche/Audi V8.

Why stop there ? Any one thinking twin turbo W12... Just kidding I think the V8's enough.

Question didn't the VW/Audi group make a W8? And, wasn't the point of that motor to fit into a Passat? Maybe that's the right sized motor for a Boxster? Thoughts?

Well the answer for the height issue is dump the roof and cut the top of the engine compartment as necessary. I doubt you're making a daily driver. Since the car will basically be a carrerra GT, you might as well go with that sort of speedster humps with mess to show off the big beast. It'd be a better show car, sound better/louder, and save some top end weight in the process.

I'll say it then. Bad idea. You lose the balance of a flat engine. I would rather have a 3.8F or 3.6F TT than a V8

Ha ha.. people for years told me the same thing about the V8 914 conversions.

Then they drove one. That additional weight (50lbs or so higher than the crank centerline) didnt make much difference to them after they hit the loud pedal one time.

Suspension and setup is NO issue for me.

Here is something to chew on:

An aluminum headed/alum. intake/ fully dressed SBC weighs LESS than a fully dressed 930 turbo engine!! The SBC will set you back $4500 for 450hp.

I have a couple of Boxster engines fully dressed that I can weigh. I need access to the Cayenne V8. I'll have to call LA P-car dismantlers and see of they have a engine from a Cayenne. I havent talked to Todd in awhile!

As an enthusiast I'd rather see a built up 3.8 Flat six putting out 380 - 440 HP Naturally Aspirated with an high red-line than a hefty V-8 in a boxster.

Since we are posting pictures of big engines:

http://www.bath.ac.uk/~ccsshb/12cyl/

102 rpm. All torque, baby.

On the idea of a V8, if it fits and doesn't throw off the weight and balance too much, I say go for it.

V8 Boxster, should be interesting, go for it!!! It'll be pretty fast with all that torque available on tap. Post pics if you do it, and when your done post the video!!! Also, someone said that the 2.7 twin turbo bolts right up, that should also be pretty interesting, both engines would be great on the box!!! Good luck on what ever choice you make

The V8 is too tall to fit in there! Two things are certain...if it is possible it will cost mucho dinero and you will not have an operational top...or no top at all!
