Ed,

   If you want to have fun with the Porch guys, stuff a GM LS3
   into   a   Beemer3. Use the T56 trans from the Firebird/Camaro and
   the diff    from a Beemer V12 car. With a bit of port work, a cam
   change and   tune it is 525HP at the rear wheels. Scare the hell out
   of the Porch    and blower Mustang guys.

   How about a 690 HP p-port 4 rotor?

   Paul Lamar

   Yup, that would do it all right. The Government Motors engine
   might be a  bit  more torquey though for street operation. How would
   the four rotor engine  length be compared to the LS3? No problem
   installing in the Beemer as you  remove the I6. They tell me the
   LS   takes 50 pounds off the front end as it  is  all aluminum and
   shorter than the I6 engine that has a cast Fe block, so it  actually
   handles better.

   Dale Davies

   It is about the same as LS1.

   Max torque is 442 ft pounds at 6200 RPM. Do you want to tow or
   do you    want to go? :)

   Paul Lamar

   Well Dale, I have a llittle bigger aspirations, than that government
   engine. And as far as the T56 goes, that's old school now. I just
   sold the viper version i had. I wanna PDK 7DT doppelkupplung,
   based   on the original twin clutch used in the 962C. Should be able
   to get   one soon from a crashed panamera. It'z amazing how some
   monied folks   love to crash their porsche. Just another fact of the
   civilized world.

   4 rotors are too much, gotta make em think they can actually beat
   ya; so a built 3 rotor turbo should be sufficient when coupled
   with   a 7DT in the back seat of a 2200lb 914 porsche. And BMW?
   BringMoneyWith, cause you're gonna need it when you lose.;)

   I now consider myself a reformed engine enthusiast. Thanks to
   Paul,   and the rest of y'all. So long to the ford/chevy
   controversy. Never   owned a government car in my life. As long as
   we throw the bumdeal   president out of office next Nov., we
should   all be able to expand   developing these rotary things out
to their   true potential.

   Governmental tyranny will soon be extinct.
   Light the candles again!
   Happy Hanukkah!

   I am beginning to really like Ed :)

   How is the length of the 20B compared to the original boxer 4?
   Might be a  bit  tight. A little grease on a shoe horn has been used
   before :-)). Even a 13B  turbo p-port would be a rocket. 914 6 would
   take the 20B no problem due to  a  longer back for the Porsche
lawn   mower.   Used Beemer 3's are reasonable in price. One fellow
in Calgary   has a  fordor  that beats blower Mustangs regularly.
They go to the   Porch track days and  lap  faster.

   You should visit the porcha club endurance events at night at Willow
   springs in May, just so you can see the fire come out of the exhaust
   on the old turbo 911s that use the original K-Jetronic injection.
   Talk about money to burn. Guarantee ya, there would be no era
   correct stock bodied 3 series bimers puttn a pass on a built up
   944/968 turbo going around turn 8.

   Its all in fun though ya know. Tons of money, club racing at it's
best.

   Ed Carver

   Like watching the 917 30K's at Edmonton. Good flame thrower
backing off   for a   corner. Donohue in the Penske car leading.
Jody Sheckter removed a 5.0l   engine   on Saturday night and put
the new 5.4l engine in for the race. Spent   the Sunday AM practice
learning where he could put the power down.   The German mechanics
were talking in German and swearing in English.   I corner
marshelled there in the '70s.

   O gawd that must have been fun. I was 12 when I got my first sight
   of one. They had gigantic turbos on those things. Something more
   than 20 years ago, a friend told me to go test drive a 944 turbo.
I   could'nt stop driving it for about a year. Never could have imagined
   how well one of those cars worked beforehand. Made me a Porsche
   enthusiast overnight. Went out and bought all of the related race
   car history books shortly thereafter.

   Now I wanna fly fast and high. The cozyIV should do it for me.

   I just started cutting the 4130 plate for the damper. Should have
it   all cut tomorrow. Then I'll create some sort of jig for the welding
   part. I plan on using the original flywheel and rolling the edge
of   the 4130 like the original where it meets up with the ring gear.

   More pics coming soon.

   I believe a 20b is a little shorter than the air cooled 911
engines that   are used in the 914. We'll see though.

   Ed Carver

   The 914 was sold as a volkswagen in europe. Just an fyi.

   Here in the US, it was available with the 2 litre base 911T
engine, and   called the 914-6. The aircooled 911 engines are on the
long side,    but fit well within the same engine bay as the
original 912 engine   does. In 1972 the type4 2 litre H4 engine was
added to the options   list. The type4 is the Vdub van engine.

   The lengths of the various engines:
   SVX=20"
   aircooled 911=22.5"
   13B=17
   20B=~22.5"~(I don't have one to measure so I added about 5.5" for
   the extra two housings). It would easily fit in the 914 engine bay
   as there is no cooling fan sticking up on top of the engine like
on   the 911 engine.

   I owned a stripped down 72 914 for a couple years with the stock
   type4 engine. Very fun to drive, even for an ex moto-crosser. A
   friend took me for a ride around the Willow Springs big track in his
   914-6 with a 3.6 race engine in it. [?]No steering wheel to hang
on   to for the passenger.

   Got the damper parts largely cut today. Don't think I can roll the
   edge of the 4130 plate. It's too tough at .095 thickness. Gonna
try   cutting a notch in the ring gear for it. The 1.25" holes were easy
   to cut with a hole saw.

   Ed Carver

   I get the idea the 3.6 engine was a blast!!

If you like brutally spectacular exhaust flames and noise, really
LOUD bangs on the overrun ...... Audi Sport Quattro rally car at the
end of the Group B era in the mid 1980s!  The factory rally cars were
reputed to be getting around 700 or 800 HP on full boost from that 5
cylinder engine!  Here is a
sample:   https://www.youtube.com/watch?v=hEK7POxpVeE
The cars got so fast that Group B was outlawed in 1986.  Too
dangerous, too many deaths!

A sport Quattro reputedly could go from 0-100 MPH in 5 seconds on dirt!

What I can not believe is the rally spectators. Drivers are flogging the crap
out of high power cars on gravel and getting air, Drifting out of the corners
and spraying gravel. Spectators stand a few feet away on the outside of the
corner.
