First startup 3.6 911 -71 RSR/RWB turning in to a build thread?
 

Hi all fellow pelicans :)

Just want to share a short clip of the first day running the engine. Unfortunately, when uploading to youtube, the quality went from 10 to 1 :confused:

The upside is that you don't have to see all the cr_p stored in the garage...& the rest of the car still remains a mystery ;)

The car is a 911T 1971 now with a 3.6 from 1991. The transplant & install is all done in house.
A huge thanks to forums like this for the information & expertise & to the local Porsche enthusiasts at home for all their guidance.

Congrats and it sounds awesome. Bet your pleased. Must feel pretty good!

That does sound awesome! What a transplant. Congrats!

Congrats! That's gotta be a great feeling.

More

Thanks :)

Yes it feels pretty awesome to have reached such a milestone. The day of startup I was a bit nervous. We had no idea if the DME would work or if the harness was fully ok.

Having only wiring diagrams from the 964 engine & the 1971 body we made the Engine Chassis Conversion Harness ourselves. There were still some issues before the engine finally fired up...but well, here we are. Finally :D


More? Yeah, there is more but there is no build thread here on the forum. Didn't know if it would be of any interest.

The car came with a lot of mysterious goodie bags & crispy fresh clusters :rolleyes:

The car had been involved in an insurance fraud case. The company suspected fraud due to a fire in the electrical system under the dash, hence the burned cables & clusters....& steering wheel....& indicator stalks & brake lever...ignition switch and so on...
The owner at that time tried to sell the car not long before the incident, but with no luck.
The car was finally sold & after a few years of changing owner it ended up in a friends garage. They wanted to restore it but didn't have the time.

So, my partner/fiancee bought it, after me inspiring (or maybe brain washing) her for a few weeks....playing clips on youtube of loud RSR/wide body Porsches, leaving my computer on with pictures of wide ass Porsches :D
May I add that she was NOT a fan of Porsches. They look like frogs & she said she would never own one....

Cool that you got it running! Congratulations!

There you are :D Thank you & a special thanks to Magnus for all the help & info he has helped us with SmileWavy

It has taken a while longer than planned & i have not visited the Porsche guys as frequently as I would like to. Honestly speaking I hardly spent any time in my own garage the past year. Having two small children is reason enough, i think.

Håkan was kind enough to lend us a set of ignition cables since only 4 or 5 of our gave any spark.

Now the engine will be lowered & cables will be tucked away, rear engine mount/crash cage :rolleyes: will be sand blasted & the oil lines put back in place after some extra welding. Besides that....we have the rest of the car to finish :D

Always glad to help if i can. Would be nice to see you if you are home around christmas?
I had a hell of a time starting my 3.6, all 6 injectors was stuck close. But I was always planing on getting newer bigger injectors anyway.

Please share the specifics related to the flywheel and clutch, this is a critical aspect of the conversion. Congrats on the Metzger upgrade

For a 915?
You get a conversion flywheel from patricmotorsport (maybe orher sources) and use 915 clutch parts.

Good point on the trans. I can't imagine a 3,6 behind a 901.

I too would like to see all the details of the swap. Sounds like a lot or work. Good luck, and I can't wait to see it finished.

Didn't you already change injectors? I think you have mentioned something about that, but don't quite remember.
We installed SAAB injectors. 2 of our failed when i tried them out before install.
The 964 injectors are at 90% duty cycle @ 250hp according to several calculations. BOSCH states 201cc/min @3bar & the 964 is set to 3,8bar.
The injectors should, in theory, hit max @ 275hk / 3,8bar.
I know several people run higher power with 964 injectors but that's nothing i would like to experiment with however.

The SAAB injectors hit 81% duty cycle @ 275hk / 3,8bar
BOSCH states 248cc/min @ 3bar

I'll be home for 3 weeks from Thursday next week.



Thanks.
Magnus already mentioned the PMS flywheel & 915 clutch parts. That's basically it, really.
Some pictures below.



I feel this start-up teaser turning in to a build- & how to- thread. Would people really be interested?

A lot of work converting to a 3.6 yes, but now afterwords no. Have in mind I have NEVER worked on a Porsche up until this one.

The paper bags we had, with all the goodies, were full of parts & some didn't even belong to a Porsche.
So we headed of to Magnus & the other guys for a coffee & little game of...what's hiding in your mysterious bag :D

When we told the gang about our lack of experience they were all glad to help out. When i pointed at a picture on the wall saying, that is what we are going to build, they got mysteriously quiet.

The picture represented a 1974 RSR. I wished back then i could read minds :D

We had a 2.2 original 1971 engine on an engine stand & no clue weather it was a runner or not. Rebuild is a must but can we give it some steroids & make it match a wide body Porsche....no.
SO we sold the 2.2 engine & started looking for a better one. After a lot of research we went for a 3.6 but prices in Europe were insane. So we imported an engine from....Vancouver.
Yes, Vancouver, Canada.

The engine was not near of what the seller/company had promised. A rebuild was inevitable. At the same time we "improved" it on some points.



Below the 2.2 engine, 3.6 flywheel/clutch...& some wiring.
