1973 E Targa engine upgrade options

Should I put the mfi on replacing the carbs. what would be the best options to increase the performance of the car ?
I want to find out what I need to do to top end the car, can you make it into a 2.7 and what components would get max horse power out of the car.

Some people may say different, but seems to me engine swaps give you the most bang for the buck.

Sell your 2.4 or 2.4 core and buy a 2.7, 3.0, or 3.2 and bolt it in.
Just my 0.02.

When my 3.0 liter went south many years ago I got the $8000 rebuild estimate(stock rebuild, no power gain) and then went out and spent $5500 on a good 3.2. A few years later I sold the 3.0 for $1500. More power, more torque, and better gas mileage.

One day I need to get a 3.6 for my 79 so I can retire the 3.2 to a leisurely life in the 72. Kinda like trickle down economics, only with Porsches.

Is that ex David Dale's Car?

My opinion is that a 73 911 is to old to make into a gruntier car without destroying the inherent charm on the car. As the last of the pre-impact cars far to 'valuable' to destroy

I recently drove my 73 911 and my 914/6 round Taupo and the 911 was like a truck compared to the 914, The 914 would be a great car with 200+ hp but I'm faced with the same issue, would you do that to a genuine 914/6?

One common conversion is swapping out the stock p&c for 2.2S p&c. This is a slip in. The other one that I liked was building it up to a 2.8 single plug. Grady Clay posted the specifics on this forum. 2.4E motor, swapped out the p&c and left everything else stock, approx. 230 h.p. If it's going to be a daily driver and you just want to get in it and go, the 3.2 is good for that. I had both in my '73 E targa. For viseral fun I like the 2.8 concept. I find my 2.4E w/carbs starts easier and has no surging vs. my stock '73S with mfi.
