maui44,
What are your DIY inclination?
Where are you located?
Since you have a nice-running properly rebuilt 2.7 and a fresh 915, keep it in your 911.
Consider buying a matching and guaranteed good running 3.2 with G50 with all the necessary ‘accessories’ from a salvage.
Find a local Porsche friend with a Carrera with the engine & trans out.
Install the salvage in
his chassis and test for compliance with the warranty.
This is easy and only expends oil, some filters and a few pieces.
This will also tell you about the transmission.
Let the chassis owner enjoy a few miles on his disabled 911.
With a few knowledgeable Pelican friends, this is a one-day weekend procedure – pizza during, beer after.
Do a thorough ‘PPI’ on the parts.
With several oil changes and some ‘break-in’ miles, preserve the fuel system.
Once satisfied, take your engine & trans home.
You now have a “known-good” 3.2 engine and G50 transmission properly preserved, sitting in the corner of your garage.
Take your time. Plan all the little details of the conversion into your 2.7 chassis (BTW, what year, model?)
Now, if the urge overcomes you …
take your time and rebuild the 3.2 engine back to new-original or …
buy new 98 mm P&Cs and the necessary twin-plug pieces and chip it appropriately.
If all this seems like overkill – it is.
However, it is fun and will keep you out of trouble.
The investment in ‘home workshop’ is doable for most and is an ‘investment’ for worthy grandchildren.
Fear not. The Forum can help you through almost anything.
Most of the ‘professionals’ use sub-contract vendors for much machine work – so can you.
Remember, a 911 engine was assembled by mortals using the same pieces you can buy from Pelican Parts and the simple skills in a workshop manual.
You have an advantage over the Factory:
time. When you have a question, you can stop and ask.
You have another advantage over the Factory:
hindsight. You can install all the little ‘updates’, just as with the 2.7.
When you make this conversion, I’ll encourage you to carefully preserve your original 2.7 and 915 for posterity.
Having the
ability to return to ‘numbers matching’ original is worthwhile.
With it clean and drip (smell) free in a glass box, it can make a great coffee table.
I hope this helps.
Best,
Grady
