3.0vs3.2
 

Any input on this

3.0 is revier, 3.2 is torquier. SmileWavy

Assuming you are looking at the difference in and SC and a Carrera.

The entire car, or just an engine? The major difference, besides the obvious displacement is the type of fuel injection. The Carrera's DME is a much more modern system that the CIS of the 3.0 engine. Neither is perfect, but the DME allows for software mapping to customize the setting to match any changes in the engine.

Are you comparing 2 stock engines or the whole car? If so what year?
Just to expand on what Glen said,
3.2L engine management is relatively modern with no adjusting required. Get in, start the car and go. CIS not so much.

If this is a comparison of the cars that they come in, more info is needed, because there were huge changes over the course of the 3.2L years ('84-89). I don't think there were many big changes in the '78-83 years.

To get good info, you're going to need to give us more to go on. You "question" is kind of like

Water or beer. Any input?

Ford or Chevy. Any input?

This sort of vague post triggers many of us to imagine...

My SC had an engine built by Jerry Woods in it. Had euro pistons (higher compression), 964 cams and was a nice rev'er for sure. I forget what it dyno'd at but it was a fair bit more than 'stock'.
I haven't had a chance to sample the 3.2L my brother has in his '74 Targa. He's working on getting the seats in it today so he can use it to go to the 356 meet in Paso Robles in a couple of weeks.

Why do you ask?

There is no replacement for displacement.


Actually, that is not true. The replacement for displacement is more revs

192hp vs. 270hp here. 3.2 wins.

270hp after $20,000

My SC was more tossable than my Carrera so it was more fun to drive.

Nope, only paid $4500 for that car.

My 2340#(with 17 gal fuel) 3.2 Carrera was pretty tossable. Of course, it didn't look like an 85 Carrera when I finished it.

I have always preferred 3.2's over 3.0s. Motronic is modern and reliable and Steve Wong/Sal Carseller chipable, which, other than weight loss, is the cheapest way to gain significant hp. You can also get to a 3.4/5 with a 3.2 case.

My most fun car is my 73 with a 3.2 with headers and "muffler" weighing in at 2174 lb.

Nothing beats the fun value of that car, you can slide it around on sticky little 205/225x15s all day long.

I have both (mostly stock)
The 3.2 is definitely a stronger, faster car.....but the 3.0 SC is more fun to drive.
I have a smile on my face all the while driving the SC.

I believe the pistons and bores are the same size, but the 3.2 has a longer stroke. So less revy.

However... a 3.2 short stroke is the business. Got the displacement and the shorter stroke.

If a 3.2 is better than a 3.0, then the 3.6 is better once again, in the same way.

I think the 3.0 makes a better platform for hot rodding than the 3.2.

CIS is too complex and unreliable. 3.2 is a solid platform, durable, great engine management, can be serviced without the use of voodoo or specialty Porsche software.
The 3.2 has been considered the best of the air cooled classics by many for the above reasons.

Just look at your steering wheel. 1984 is the year Porsche stopped caring.

CIS = Warm start problems for those who should not be effing with their cars.

Motronic - slightly different logic except only one bank pisses fuel in pulses vs all six cylinders all the time. The barn door air sensor is vastly superior to the CIS air sensor. Pfffft.

Both are dinosaurs. Good dinos each in their own way.

Fight me.
