1973.5 cis injection replacement

[Princess]

cis injection on a 2.4, Wanting to replace with weber carbs.
Ive got the carbs, Manifolds and linkage.
Not sure about the fuel pump, Fuel Regulator, Ect.
Do I need to change the injection fuel pump or can I
buy the PMO fuel regulator from pelican and have it
tone down the P.S.I from my current fuel pump?
Any Advice, Suggestions, Experience Greatly Appreciated!
Car is a 1973.5 911T 2.4 with cis injection.

Gotta ask why you would do this?

Piston dome shape and cam profile does not lend itself well to carbs.

Car was parked for twenty five years, Got
The engine to fire up and run by pouring small
Amounts of gas down pop off valve.
Injection is Brittle, Frozen and in need of
Expensive replacement NLA parts.
Just want to get engine running and
911 drive able.

This came up on Pelican, and I was told the CIS cams work well with Webers.
I got rid of the Webers on mine and went back to CIS. Much better for every day driving. I've seen quite a few 73 cis systems come up over the years. I currently have 2 setups, the second one cost about $200. It was dirty and needed a lot of clean up. but the components were all good. Many parts for the '74 are interchangeable, aside from the intake runners and injectors. I was able to get the piston rings from PartsKlassik. NLA everywhere else. They told me they had Goetze do a run just for them.
Pelican classifieds seem better the parts, not many cis on this forum.

Thank you E Sully for your input, I'm going
To attempt to buy the CIS parts that I need
And keep it original. Obviously I'm a complete
Noob!

Princess,
You're this far along, try the carbs. You may like them. There is nothing really wrong with the Webers. Webers are fun and it adds a more sporty sound to the car. Minor drawbacks, cold starts are a little difficult without a choke, gas mileage will be lower, it will take a bit to get the jetting right.
I don't know if you are doing the work yourself, or paying a mechanic. I do 90% myself with helpful hints I pick up searching the forums, and talking to the guys at the local Porsche shops. I found the cost of Webers to be more than fixing the CIS. Most have been used quite a bit, and having them rebuilt by the qualified shops can cost quite a bit if shafts are worn, passages and jets are clogged, etc.
Scan the Classifieds for deals and pick up the bits and pieces for the CIS when you find good deals. Like anything else, diffferent people sell at different prices. Like I said earlier, every once in awhile I find parts from people like you that switched to carbs, or swapped out to a 3.0 or 3.2 and sell the CIS or complete engine cheap. Others want big dollars since it is a unique 6 month only setup. If your engine is original to the car, saving it will keep it's value higher down the road. Like I said, I ran Webers, I also rebuilt and ran a 1986 3.2 in the car for a few years. The thing I like to do is save all the original parts, and any modifications must be easily reversible. I'm older now, and while it was fun modifying things in the past, right now I'm restoring it all back to original.
