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 am one of the guys who said that the Zeniths are not optimal for the 2.2E. But the engine can still be made to run well on them with correct tuning and linkages. I agree with the guys who say to get it running on the Zeniths. You own them already.

One of the reasons I spent the money for a 993 3.6 is that it would have cost me more money to build up a good 3.0 liter case and then end up with less power, worse fuel economy, and much more time involved. Intakes and spark methods for these engines are quite expensive. Stick with what you got for now.
