Should I get new carbs on my /6 2.2l 911e motor? Options

[tornik550]

I recently purchased a 911e 2.2l engine. Befor I install it in my 914, should I change carbs? A previous owner at some point changed from MFI to zenith 40 tin carbs. From my understanding, this is probably not the best setup for a 911e 2.2? I have looked at the different options, which do you think is most appropriate taking cost, hp/torque gains, drivability...

1. Leave the zenith carbs
Pros- I already have them
Cons- probably better forming options

2. Change back to MFI
I probably can't do this one. I have no where to obtain the setup and I really am more comfortable with carbs

3. Change to weber 40 Ida's
Pros- ? Power?
Cons- expensive. Most likely between $2000-$2500 after rebuild

4. PMO carbs
Pros- improved overall performance compared with the zeniths. Easy setup. Is it worth the cost?
Cons- very expensive-$3600.

Here are some other things that I am doing to the engine other than basic maintenance. Pertronix for the distributor, new plug wires (clewett), msd 6al (I already had this), msds headers.

I do not plan on racing this car anymore, just spirited street driving.

I see you have an ad wanting webers, I'd really stick with the zeniths for now. I've worked on the zeniths and they are good carbs. The ones I've worked all were set up all crap often linkage issues or vacuum leaks. Guess what...Webers will run like crap with linkage issues and/or vacuum leaks.

I'd get what you have sorted, drive it, then you can think about upgrades. At least that way you'll know if the changes you did made any difference.
You have a lot of work (and money) ahead of you, don't get bogged down obsessing over an known running engine.
