It's been a while but this seems to be the place to ask "dumb ass questions" per FB K series groups.

I have a K swapped Insight with the goal of power AND economy, I've had a K20a3 with 11.5: compression and 5psi of boost, 3.4 final drive and while its a blast to drive I average 30mpg with 40mpg being my tank record. Meh

I now have a K24a4 on the stand and will be swapping it in next year. No turbo, well muffled. Stock compression is 9.7:1 and made for 87 octane.

I'm interested in running higher compression on 87. TSX engine is 10.5:1 which seems possible. what about higher?

My thought are that the car is almost half the weight of the original Element/Accords the engine came from so the load will be less.

My other idea is to add EGR to the system and control it with Kpro or maybe another means.

Also FWIW I fully expect less power than my current setup and I'm cool with that, I have other cars for that.
