Out with the old. Anyone need a 2.7? The Audi V8 arrives Friday (I think), 8 weeks or so until tools down and baby arrives.

Well I've also had some enormous scope creep. I decided that lifting the car 2 feet off the ground to pull the engine from below is absurd and I don't have enough faith that I can service the Audi V8 with the factory engine cover in place so I did some cutting... I removed he entire engine surround and fire wall, rear trunk and moved all the electronics to the cabin I'll make an aluminum firewall that goes all the way to the roof and will either install a plexi window or install a hidefinition rear camera that uses the a rear view mirror as a screen (oddly the cheaper option). With the rear trunk removed I can now just wheel a new motor in instead of lifting the car up and pulling it from underneath (especially valuable with the tall V8 compared to the flat 6)






you can see in the above photo I'll need to add some rear chassis reinforcement, I'm going wait for the engine to go in and then tie something into the cage to strengthen it


I also added a third radiator thatíll sit under the hood scoop (feed from the front of the car and cut out the original rear quarter panels (that now sit under the widebody) to make room for...intercoolers

Parts for the turbo build have started flowing and Iíve started the mock up. Hereís one of the two side intercooler radiators (the water cooling rad).



Air will enter here


And exit here (the gap between the outer fender and tail light


Iím a little bummed about the weight, theyíre probably 25lbs a piece. Iíll have close to 100lbs in my intercooler system including the water. All in all Iím probably adding 200-250lbs to the car in engine, turbos and cooling, so far Iíve found about 40lbs in steel that I was able to remove. Hopefully I can find some more. I still need to remove the HVAC system under the dash, anyone know what that weighs?

That's going to be vicious. Do you think it will handle more like a 911? Really enjoying your journey.

Hopefully not fortunately the engine is in the middle so adding weight to the middle of the car shouldnít change things much, weíll see. Iím sure the additional power will change just about everything though, in the past throttle control rarely came into play, I was either off throttle or on full throttle. The car never had enough power to need a light foot. Hopefully the 315 series Hoosier will help, the open diff on the other hand...

I need to upgrade to a 6 speed first but thatís a great option. Not that $1,500 is cheap but Iím surprised itís not more expensive.

This is really sweet. Badass looking car, I'm taking notes.

Some random quations: What's the offset on your rear wheels? Any clearance issues? And I dig your frunk mount radiator. That was the origional plan on mine, but we ended up going a different route. I'm also very much considering s̶t̶e̶a̶l̶i̶n̶g̶ borrowing your widebody design.


One of these days, we need to meet up at VIR.

Here’s a link to the rad, you’ll need to cut a huge hole on the front of the trunk and bumper and make a hood vent (I made one out of aluminum but you could buy something off amazon I’m sure). Plumbing this thing up is no proving to be very difficult. The Boxster has two coolant hoses going forward and two back so you need to make some complex manifolds to make it work. Still a work in progress.

Thanks! The rear wheels are 12Ēs wide with the hub right in the middle of the wheel. I donít have fitment issues but the fenders are of course not factory. The front is 8Ēs wider which I accomplished by extending the front suspension (I didnít change the offset of the wheels). The rear fenders were actually really easy to make I used .125Ē think aluminum (super super thin). It canít even support itself unless itís bolted down, but onceís secured its rock solid.

Do you really need the fans for the middle radiator? I take it you still got the fans for the outer rads, then the speed will likely give enough flow for the middle one. Itīs obviously not a road car that will be sitting in slow traffic, so Iīd suggest you get rid of that extra weight!

Awesome! Thanks a bunch! I'm using a toyota corolla radiator with an electric water pump right now but the radiator isn't up to the demand I'm producing with my rally boxster. I have to say I think your boxster build is the most intriguing build ever. My hat is off to you. Keep it up, it's very entertaining.

Good point..Iíve removed the fans from the outer rads for this reason. I probably donít need any fans and could just place a fan in front of the rad in the paddock once I come in if I want the car to run and cool down.
