2.0 or 2.3 for highway runs?
freeway running is all about the turbo... not the displacement. as long as you have a turbo that don't run outta breath in the high rpms it doesnt matter if you are stroked or not.
if you have a stroker and use the stock turbo you'll never do freeway running.

Same built 2.0 that you can buy.

Look at the graph from TopSpeed of the 2.0 vs 2.3. The stroker was making over 170ft/lbs more torque at 5000rpm!! Thats significant enough for me.
If he asked about dragging the car, Id say 2.0 because after you launch, your sitting at those high RPMs until you go through the traps. Not so the case for roll-on racing!

However, I suggested the 2.3L since he said highway for a certain reason and thats the powerband, especially initially. If youre going to be taking off at 5000rpm, the stroker will annihilate a similar setup 2.0 car (same boost, turbo, etc).

should be... which turbo should i use for freeway running on a 2.0 or same on a 2.3.

He is correct.
If you were to ask how to get from 60-125mph, the answer would be different. It's the earlier shift into 5th that limits the high speed performance of the 2.3 with the factory gearing.

stroker?
With the factory gearing, 121 mph equals 7500 rpm, which I feel is a safe maximum rpm limit for a short rod, long stroke 2.3L 4G63.
If the final drive is changed from the stock EVO 8 4.53:1 to 4.11:1, that 7500 rpm figure equates to 133 mph. With a large turbo and enough power, a 4.11:1 final drive makes a 2.3L 4G63 a more attractive option.

How much is enough power?
I spin to 8500 no problem on the stock engine. So if you are only planning 8k on a built motor your crazy. At least 9k on a built motor. BTW the 35R keeps building more power for me all the way to 8500.
