pics of the manifold, by yours truly...
Not. j/k, it was made by a local racing fabricator.. |
Did your RB flange warp at all?

I have been fallowing this post for a while. I must say that you have nice taste. When I do my 20b I'm going to have custom flange made for me in stainless steel.
|
This thing sounds fucking great and looks the part too. I'd post the video but it displays your plate # and I noticed you blocked it out in one of the photos so I'll refrain from doing so.
I can't wait for you to get the setup dialed in and tuned. |
If anyone reading this thread has interest in a 13B Turbo Porsche conversion, mine is for sale!

any updates Fred? Have you broken in the motor and dynoed it yet?
How about a bunch of pictures up of the car.... like a full walkaround inside and out! It looks pretty damn well built and plenty of us would love to check it out. |
liking what i see :)

Car is going back to the body shop for some misc work, going to re-do the exhaust yet again after that. Then I'll need to install Electronic boost controller, water injection stuff before dyno... So I'll be busy for a while. |
Got the car weighed... It's a bit of a porker at 2735 lbs (~15 gallons of fuel). Need to putting it on a diet soon. The car weight the same with the Porsche motor, BUT with fiber glass doors. I've replaced the fiber glass doors with much heavier steel doors since, and added radiator in front, extra lines and an oil coolers.
So engine wise, it's 150lbs to 200lbs lighter than the Porsche 3.8 motor with twin turbos, even though the S475 turbo is literally 50lbs... Going to replace the full size battery, remove some carpeting, and all the Dynamat insulation stuff... |
I would keep the Dynamat..... those 20B's are loud! :)
LMK when Steve is in the area. I'd like to check it out on the dyno! |
Very cool swap... can't wait to hear about final numbers.
|
Any updates?
|
Been too busy lately to do any work on the car...
However, I had the car tuned by Steve Kan, it felt great on the street. However, when we put the car on the dyno, it wouldn't dyno properly, I couldn't boost over 10 lbs (when I can hit 15 psi on the street np), and the dyno stops at 320 lbs of torque or so... Still have to install a couple of things... Will try to dyno again in a month or two. |
more picture please!!!!!!
|
And video too!
|
sorry dudes, been working night and day trying to launch a new venture... Will resume project in a couple of months. Still need to redo exhaust, fix boost control (found a big leak in where the double throttle rod used to be, as the plug got blown out, thus the boost problem during dyno), get tach working, install water injection, etc..
|
Looking good! I don't really like seeing 6's or 8's in a rotary, but seeing a 20B in a Porshe is a nice combination. Looking forward to updates on running and performance.
Well done in being different! Cheers! |
Any updates on this project??

Car has been shipped to Defined Autoworks, Logan will perform some much needed cooling and other fab work including a dry sump system. Can't wait to see how it turns out!

awesome project btw.... gotta love unique stuff like this! |
Okay, so some progress has been made after careful thought and planning on the cooling systems and oil systems. Basically the front radiator had massive blockage directly behind it from the flat front end of the 911. First step was to remove the sheet metal, and build in/ weld ducting behind the radiator. Although crude looking now, it will be a very nice front end once complete :)
http://i254.photobucket.com/albums/h...a/DSC01871.jpg http://i254.photobucket.com/albums/h...a/DSC01870.jpg The twin side radiators are being replaced with one, better flowing and cooling aluminum radiator. The other side will have a setrab oil cooler up front, and all of these will be very neatly ducted into respective channels from the bumper. Here is a crude diagram of what the setup will be like. http://i254.photobucket.com/albums/h...checooling.jpg Now on to the back section- Once everything was removed we found one a coil that shorted out, which explained why it ran on two rotors during our test drive! We will be going through massive amounts of wiring on the engine and chassis to get it to Freds specs. The electric waterpump has been removed, and we dropped the engine mounts. This allowed us to set the engine height as it will be with drysump. Once at this level there is just enough room to fit a series 4 waterpump in it. We will be making custom inlets and outlets and running the lines up front to the coolers with 1.5" tubing. http://i254.photobucket.com/albums/h...a/DSC01872.jpg http://i254.photobucket.com/albums/h...a/DSC01910.jpg http://i254.photobucket.com/albums/h...a/DSC01909.jpg http://i254.photobucket.com/albums/h...a/DSC01911.jpg We have built the pan plate, and mocked it up on the engine. Next will be making the new motor mount system and running the lines to the coolers. More pics soon! |
