I just finished my build of a ported 2300, H/C, pulley change, Already had the lowside, meth and flex fuel, headers in place. Made 775/734 on 91/meth and 862/834 on E50/meth. That is on the 80mm upper pulley. When we had the 70mm upper, had 22# boost but some belt slipping issues. CPR did the work and it is solid. Here is the final dyno numbers.

So looks like a 100whp gain or so going to the 2300 if your bolt on setup was also running on ethanol to make it a fair comparison. Im guessing this is the previous gen 2300 not the newest rotor pack I keep hearing about. How are the manifold temps? If the car is consistent from summer to winter or close that is well worth the swap. Thats the biggest issue with 1.7 is it seems they can go fast in the better weather but slow by an easy 5 mph in the summer. Will see this year as been 9s a few times at different tracks local to me and hotter fl weather will soon be here to see how bad it hurts the setup. Im still waiting on a 2650 maggie or a lt5 swap I have low 9 to high 8 second goals well really 150 plus mph trap speeds is what I want from my set up.
Good looking setup really like to see some logs if you have any so can compare temps and a few things.
I am sorry if the dynos are miss labeled. I picked up almost 200 with the swap. The bottom graph was the maxed out factory unported blower, 675. When I did the swap with heads and cam, I got to 860. I do have a larger HX and tank. I was on E85 before but can only get to E50 with the new setup.

It's crazy how big of a hp bump you get with e85, too bad it's not an option in oregon.
