Boxster V8

[rusty69911]

I think integration with the electronics of the Audi to the Porsche ecu is much more important than a dry sump, that make this a simple swap, why does the intake not fit? it seems to fit fine for the other conversions that have been done?

It is extremely torquey with the six speed automatic and believe it or not puts a lot of cars to shame stop light to stop light. The Caddy turbocharged V-6 (same basic engine architecture) puts out an easy 450 hp and they are starting to show up in the scrap yards. Think about it a second. A modern GM engine, turbocharged that any Chevy of Caddy dealer could work on. I love V-8's (used to have a 1974 454 4 speed Corvette) but they will be disappearing in the next few years. Even Porsche is downsizing their engines. Have you seen the new 718 Boxster? It comes with a turbocharged flat four!
Now everyone can laugh at me but I speak from a base of experience. I worked at the GM Tech Center many years ago and I can tell you that engine design and development is not standing still. A turbocharged V-6 would be perfect in a Boxster.

It is a neat concept, however if you did this and pulled the Boxster into a GM dealership I doubt they would touch it. I think any of the radical modifications we see and talk about presumes that you will be your own master wrench

One of my track buds is putting the Caddy turbo V6 in his Cayman. It's a track car so he has less hurdles than a street car but this should be a monster

I'm doing a turbo V6 in mine. No point looking any further than the Audi 2.7 bi turbo engine from the Audi S4 which is what I'm using.

s4 and a6 motor has the power. I personally love the sound of a v8 in a sports car

Not to mention Ive found a local motor with less than 60,000 miles for $500

Any updates to the project? I've been poking around the web looking at some other trails of this swap and most of them end before completion. Also I'm curious if (after development) you plan on selling the separate components or just the complete kit?
I've seen some good deals on the 5V engines (BFM). I might pick one up and start working it into my rear clip (no 3d scanner or CAD here, but a Sawzall and lots of curiosity).

[GTA_G20]

From what I recall. You choose your own 5v and he sells the install kit

I'm waiting on an update to buy my motor also

Hi there,

No updates other than we are working on it. We have many projects on the go and paying clients projects always have to take priority. Thanks for your interest. Please feel free to PM me with more information about your particular situation.

Regards,

Dave

Not to hijack this thread but I'm looking for a engine swap in my 987.1 Box S. So DME 7.8 can't really be integrated with another ECU even in piggyback fashion. So the donor motor's ECU and harness need to be used. The rationale is to stay with VAG as they may use common sensors and gauges so if you can find an ECU/DME that is open and can be programmed to the Porsche? There's also dimensional constraints of the motor to consider but that's fairly easy to figure out.

Is the 4v ABZ the best choice to integrate into the Boxster S? It seems some people here feel there's other options that might integrate better.

Will the Cayenne engine just not fit or too low output or what ?

They seem cheep compared to 986 and up engines.....even 30 to 50% less than Boxster engines when price comparing ???

There was some discussion of it in this thread with pics of an engine in post #193:
Boxster V8 conversion !!! - 914club.com
...but then it got side-tracked into an LS swap instead.
Maybe Brad Roberts can elaborate a bit if you can track him down. I know he posts here from time to time.

I should scan the Cayenne engine just to compare. I have a twin turbo V8 here that is in an '06, that in the Boxster would be absolutely wild.

ABZ is not the best choice. Found that out after test fitting a couple other VAG V8 engines.

^ Hurry up and make the swap parts! I need more V8 sounds coming out of my Boxster.

I'm a mechanical engineer... if you don't have the time to complete the design but have everything 3D scanned, maybe we can come to an arrangement...

Over on Piston Heads there is a very long and interesting thread on transplanting an Audi V6TT, yes 6 ,not 8.Found by Marcus.
Yes, they show the practical process - not just dreamers !

And yes, it fits and there are photos
