Well, being a technical person who built tons of nitro RC cars, I'm very curious how those engines works, and the extra knowledge may help me with future tunings, or even tuning my car myself
1) PSI? obviously more turbo pressure is supposedly able to increase power output, straightforward. But, this may not be 100% the case of there are other limiting factors, like exhaust.
2) Bigger Turbo. Another straightforward upgrade. But what's the downside? more turbo lag? faster heat soaking? My understanding is that too big a turbo can be slow to kick in, resulting uneven power delivery throughout the power band. Don't know how much tuning can solve this.
3) FP, DP. Part of the exhaust system, definitely on top of the list. Turbo is all about intake and outflow.
4) CAI, and HVI. I know lots people just get intakes for the sounds, but I think with good tuning, a proper intake can contribute a lot to power increase.
5) Intercooler? sure it help with maintaining optimal power output on longer drives, but I don't think this is a direct one. I feel It has to couple with a few other bolt ons to show it's benefits
6) Weight Reduction. Technically not increasing horsepower, But, you definitely would feel more powerful. Let's say for the civics, -8 kg = 1 extra horsepower felt. If somehow you manage to take out 200kg from the R, That's about 25 extra horsepower equivalent of performance, with better cornering and everything. you will feel it definitely.
I didn't mention fuel because most of us won't bother with those hard to obtain race fuels.
Add in what else you think belong to the list, and feel free to correct, if you are very sure.
