Yeah, I saw that too. And have stated my disagreement with it. But its his car. I believe he stated it was just some leftover scrap metal he used to quickly make a cover. But if you look at the pic of the Renegade Car, he still has his center console in tact, his stock carpet in tact. Might have a lil extra buldge but you wont need to lose soo much cabin space.

The first photo I posted, is Martsinks photo also.

And actually, I'd love to see John's firewall, or even Renegades... I have yet to see any photos of these done. Just read up that most of the stock stuff can fit back with some mods. Like the top cover, cut out the hole for the TB/Pipe and the cover fits.

This is the ugliest damn thing I have ever seen! Who the "!!!!!"
would cut up a car this way, let alone a Porsche?

You obviously don't know what your even talking about. There is nothing ugly about it. Maybe Martsink's design of a firewall, but that was his choice. And what does Porsche have to do with it?

Stock 5.3's have put down to the ground, 250whp, where as a stock Boxster S will see 200. Stock 5.3's with just a turbocharger and tune can and have put down quad digit HP numbers and even more Torque, no internal modifications. And to input a LSx into a Boxster, only mild cutting and rewelding to "in the way" unibody is required. Its been done a few times already, and as BoxsterLS376 has shown, has been done to easilly gain 450whp (Wheel Horsepower, not Flywheel) to look stock, and almost sound stock.

In Fact, John does a lovely job to make it look as stock as possible.

Anything New on the Audi Swap in the spirit of SEMA opener
 

Hey Nerv anything new to report on the progress of the Audi swap?

The silence is deafening~

I wouldn't hold your breath.

Well it would seem I have to come on here to see if there have been comments, as I'm not being notified.

Progress? Well, we keeping putting hours into this as time permits. I wanted to have this finished by now so guys could get the kits to work on the cars during the winter. Oh well, as soon as it is running, you will all be notified.

Don't worry, this is on project that isn't getting dropped, we have too many hours into it now! Hahaha!

At least she'll be pretty. So what if almost no one can see the engine? The owner will know what she looks like, maybe carry around a binder with photos so they can show others if they ask :)

Be in touch!

Dave@Nerv

One would think like all of us who have put forth an interest in your concept/kit, you would have already created motor mounts and installed the engine and mounted transmission into a boxster frame before spending all the CAD time you say you have done on fabbing parts (ie:dry sump and intake) . Do you have photos of the ABZ in your donor vehicle sans intake and pan? Please pm me when you have something of substance as I'm done with this thread until then. Good Luck.

Good day everyone!

As requested by BC993, some photos of the engine in the car. The scanning is a time consuming process that isn't finished... but I can still give you some shots of the actual car to give confidence in progress.

The dry sump isn't necessary but intake changes and new components that allow for front engine mounting are.

The RHS timing belt cover should be remade anyway, half of the front mounting may be off this cover, because of the extra bosses it has already built in. The alternator and air conditioning mounts may both be redesigned and rebuilt to swap their locations for easier A/C plumbing. This is no small task due to the complexity of the alternator mount because it has the oil cooler and filter assemblies integrated into the mount. Many people get rid of this design but for this specific application the cooler/filter design fits well. If they are redesigned likely the mounting needed for the front will be built into these.

Independent throttle bodies are in the works for the intake, to get the OEM unit to fit without cutting anything it would put the engine/transmission a little low and still there is almost no space for the OEM throttle body. We have both the 4V ABZ and 5V V8's here and although there are some design changes to the 5V that make it a little easier to install, I think with ITB the 4V will still be a better choice. With the length of velocity stacks that will be used and losing the 2 length intake system the torque will drop but max HP will increase thus reducing the strain on the OEM 5 speed transmission. A new flywheel is being designed as well that will accept the 10 bolt crank pattern and actually place the timing ring in the proper orientation for the manual transmission pickup location.

That is it for now, I'll post again soon once we have machined some of these parts.

Dave@Nerv

substance
 

Nerv,

That looks like "substance" to me. My S sits patiently waiting for a heart transplant so I will not turn the channel. I will continue to follow your progress.

Thanks for the update.

would the dry sump let you get the engine a bit lower and perhaps make intake and accessory fab a bit easier? itbs are tough to do well on this car as it is pretty hard to get cool air in there.

Radium King:

You are right, the dry sump is the way we need to go. Changing the intake design other than redesigning the throttle body to manifold adapter would result in such a major change to the engine that keeping the OEM ECU happy with all the emissions components that need to be retained would be a huge task in of itself. With all the parts that already need to be built, no use making it harder yet.

With the dry sump I can lower the engine as far as possible and moving it further forward which will improve handling as well.

I'll keep you posted.

Gm v-6?
 

I have been reading this thread with a lot of interest. After getting out of my 2013 Chevy Impala LTZ it occurred to me that a really great conversion would be a GM V-6. The one in my Chevy Impala puts out 310 HP and will easily rev up to it's redline of 6800 rpm. 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.

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 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

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

Did you consider the FWD 6-speed transmission from the B6 chassis A4?

Pros:
- Crank position sensor is in the correct location
- You can use an off the shelf flywheel and clutch
- Correct starter location for the V8
- 01A based like the Boxster transmission

Cons:
- Have to design shift mechanism since these are rod actuated and the mechanism is on the LH side. The kit car guys might have something in existence that works already though.
- Mounts - but you're designing those anyway.

Unknowns:
- Axles, but you might be able to find an VW/Audi axle that works.


I have actually purchased a 2.7tt to swap. I was looking for a base 2.7t 2000+ car since that Motronic version integrates better with the ME7 based 2.7t and V8 Audi stuff than does the older non-E-gas Boxsters. I ended up finding a nice 2003 Boxster S which I plan to keep H6 for the time being. So swap plans are on hold.

Until this point I've done a lot of thought about how I'd do the swap, but no actual measurement since I didn't have the Boxster to take measurements from. I also don't have a $80,000 laser scanner available, nor a machine shop, despite having used those scanners at work and having mechanical design and CNC programming experience. I wish I had your resources! Let me know if I can help out at all!

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).

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

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

Any updates on this? Really interested and could use it, yesterday.

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.

Ask this again
 

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.

Regards,

Dave @ Nerv

^ 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
