 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.

 Dale Davies

 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.

 Dale Davies

 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.

 Dale Davies

 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!
