Boxster V8

[Gelbster]

I have had many salvage title cars.Have 2 now.Never had a problem with insurance. Title is a piece of paper with one different word on it. I buy cars,not paper. There are lots of badly repaired clear title cars out there and ones with 'washed' titles.
Usually Salvage title cars are 1/2 KBB. That is a lot of spare change for the modification budget.
Never had a problem selling them.Keep in touch with the buyers.Obviously you have to know what you are doing.

If your V8 is Calif Smog-legal, easy to fit and less than a rebuild -it is an irresistible option when the M96 dies.
As long as it makes a bit more power and torque ,I would be happy. Be serious ,where on the street can you sensibly/legaly use much more power than a 3.2l M96 ? I would rather improve my driving skills than chase 400hp objectives.
Renegade -look at one -closely & talk to an owner.I did. It is a hack job.
Nerv, thanks for discussing this,it could save many otherwise excellent cars from the M96 disaster heap.

Yes, perhaps that works for you, but I don't think you are in the middle of the bell curve on this one. I'm guessing that folks that are contemplating the idea of a V8 in their boxster are DEFINITELY looking for an HP gain. I have ridden in a 500 hp boxster, and it IS AMAZING! Yes, would be worth every penny of $20k. No, i don't need 500, but as stated elsewhere, 400 seems like a reasonable minimum. Honestly, if there is no HP gain, it's a lot cheaper to surf craigs list and just buy a different used boxster.

I also doubt there is any realistic way to get this to work in CA, so it is mostly academic anyway :-(

Go here and read about the Boxster V8 conversion kit. Even they say forget the base model.

Yeah, nice guys over there, but I'd take what they print with an entire salt lick. They, when pushed, couldn't point to one successful CA smog legal car. If there is one, it's news to me...

That said - does ANYONE know of a CA smog legal Boxster that has had a non-stock engine swap? Now THAT would be an interesting conversation...

I'm thinking: man, it's a shame that people have to make Frankensteins out of their Porsches because Porsche has no viable alternative.

I'm hoping my motor last a long time as I'm dropping some coin on it right now to get some more power out of it, but when the time comes a V8 would be awesome. An LS-3 engine is very reliable, has lots of power, cheaper maintenance, hopefully cheaper to buy when my motor does kick the bucket, and the sound of a V8 coming out of this car would be sweet.

Will yous also offer parts separate? I maybe interested in the wiring harness and flywheel/ clutch kit.

[Gelbster]

500hp ? Insurance? Smog test in CA? Impractical.
I am not a rich man. I'll stick with salvage title ,less than300hp,reasonable insurance cost, fewer tickets. The cost of 400+ hp is a fantasy.And for that kind of money I have more interesting fantasies & imagination?

[BOOTLEG]

I too am interested. My 01 Box S is waiting patiently for a heart transplant. I am evaluating the LS, Audi, Subaru or just an EBAY PMotor. Each has pros and cons. Will the Audi bolt right up to my 6 speed? Is there a source for mounts or do I have to make my own? What about ECM? A kit would be nice!

[itsnotanova]

The audi 4.2 or 2.7 will bolt up to a boxster 5 speed with no problems but the 6 speed doesn't have a provision for the audi starter. The 5 speed is on the right, 6 on the left

Hi,

has anybody checked if Mercedes engines will fit? I ask, because Porsche used NAG1 AT transmissions for the 928, 996 and 997. So in general it also should fit for the Boxster engines.

The M112 and M113 defintely do have another engine charasteristic than the Porsche engines. But they are cheap and reliable compared to the Audi engines. And they use a similar Bosch Motronic version.

Exactly! That's why a V8 conversion would likely not be your cup o tea...

[Smallblock454]

The 722.653 is the 996 transmission. It can handle up to 800 Nm of torque.
The 772.657 is the 997 trasmission. It can handle up to 920 Nm torque.

Both AT transmissions are built by Mercedes-Benz and run a MB AMG software.

I think the shoud fit to Mercedes M112 and M113 engines if you use the front torque converter housing and maybe the torque converter of the MB transmission. But i can not validate that. It's just an idea.

@ KRAM36: On your pitures is the torque converter missing.

I just pulled those pics from an eBay listing.

http://www.ebay.com/itm/Porsche-911-996-Twin-Turbo-Transmission-Tiptronic-Automatic-2001-2005-A96-50-/171242163787?pt=Motors_Car_Truck_Parts_Accessories&hash=item27ded40e4b&vxp=mtr

Actually this is what mine should look like. The other was from a 911 and this one is from a Boxster. Looks to be more common to the 5 speed on the right.




Also looked at another Boxster Tiptronic and it had this on it.

1. Dismissing California Smog rules is short sighted. Other States seem to blindly adopt them. So I suggest the availability of a CA smog compliant engine is vital.There are Audi V8 Ca smog compliant engines.
2.The insurance issue is another hurdle. If an insurer 'sees' a massive increase in engine displacement and power it will be prohibitively expensive to insure . The alternative is to 'forget' to tell them .That is the same as no insurance +fraud+ unlimited personal liability.Not good if you own a home.
There is a milquetoast solution:
The Audi A6 3.0/ 3.2l 32 valve FSI V6 from the A6.255hp. On paper it would pass Smog,be insurable, fit easily(shorter but 1/2" taller than the 3.2 flat 6),same bolt pattern?
It may not be exciting but it is practical and highly tuneable.

I don't think my insurance company would care less about what engine is in it. They pretty much base insurance off your age, driving record and the value of the car.

[Gelbster]

Try calling your insurance company and telling them what you are planning to do.Then report back with the name of the insurance company if they "don't much care". As the owner of an over-powered hot rod car ,I would love to know. You can get away with it on much older cars as 'agreed value/collector car/less than 3000milesper year type policies-as I do with full disclosure.But not on a regular insurance policy.
That means in effect you are uninsured if you do not declare complete details of the modification in writing to the Insurance Co.
Just google Insurance+disclosure material+fact,insurance fraud.

There are a few very specialized Insurance Brokers who do this work ,but they are very expensive.
It is misleading to suggest otherwise.

There is nothing in your link that suggest putting a V8 in a Boxster will cause you to not have insurance. Insurance is cheap on these cars, you can do just as much damage with the current engine that's in. A V8 isn't going to matter.
