Any progress on V8 engine swap options?

[B6T]

When guys swap the VR6 into the B5 chassis they need to modify the hood latch due to interference with the engine. In the Boxster, this point would be the engine cover, much in the same area where the forward part of the V8 intake manifold is interfering.

I have just got my Audi V8 swap up and running in a 2003 boxster S.

Using a 2001 A8 engine. DBW, Can Bus all working on Audi ECU. Currently has a Cayman 5 speed mated to it.

Transmission in standard location, had to cut the engine bay and fab a new cover.

This is a race car, so not concerned about packaging as much as practicality. Air intake has been moved to the trunk for ease of install.

Running electric power steering and no AC. Just the alternator driven from the engine.

Did you modify the front firewall at all? My cam covers were pressed against the firewall until I hammered and cut a little more space.
It that a custom shifter cable? It's a tight fit over the top with stock.

The huge pulley on the PS comes very close to the parking brake cable. I haven't decided how I want to go yet. I am still considering keeping the AC, but will probably end up with an Ice-chest type cooler.

What do you have for a engine mount/subframe? I paid way too much to have a local fabricator make mine and after bringing it back 3 times gave up on him. I can make it work, but I'm not happy with it.



What axles, any modification? I'm not familiar enough with the Cayman 5-speed to know if it takes the Boxster S axle.
I've got an '01 5-speed going into an S and the 5-speed axles will work, but just barely fit for the nut:

No problem with the cam covers. Have maybe half an inch of clearance.

Cayman S shift cables re-routed to the rhs of the engine. A six speed will need the two cables split and run either side of the engine I think.

On mobile, so can't post photos. Will get some and post later.

I built a custom cradle using the stock front mounting location and a custom cross piece much like yours. But mine doesn't sit as low. I used the Audi engine mount aluminum pieces with Jeep rubber blocks to provide a little isolation.

Have another car on the lift right now, but I'll post photos once it goes back on.

I used 2006 Cayman S axles, uprights etc. Basically all the running gear is from a Cayman S. The different abs sensors were plug and play with my abs unit.

Good stuff, thanks.

Looking forward to seeing more of it and seeing more of these swaps get completed.
