I actually just got a 2018 mt civic hatchback lx with 4K miles. Just wondering, what kind of mods have you done to it besides the k tune?

Nice, are you happy with those mods? Was it worth it for you?

honestly im satisfied with what i have. Its not too much and its not too little its my daily so i like to show it off little for car meets and stuff but im not throwing thousands of dollars in it for a car show as a daily its just a waste for me at that point.

Ktuner basemaps are probably as high as you should go if you want to keep it as reliable as can be. The non Si engine cannot take the punishment the Si one can.
theres a stage 1 tune for the non si which will run 18psi and the next one up is 21+ psi. would you recommend anyone the stage 1 on 18psi to run as a daily or would you stay with a stage 0 tune which bumps up from stock 14.5 psi to 15.5 psi?

What are the actual differences between the Si and Non Si 1.5T motors? Valves? Pistons? Rods?

Parts that are different on Si 1.5T engine:
Intake Camshaft
Turbo Assembly
Fuel Injector Set
Pistons (Si has a lower compression ratio at 10.3 from 10.6 to handle more boost)
Connecting Rods
Powertrain Control Module

For the transmission:
The Differential, Mainshaft and Flywheel are different from the standard 1.5T 6M.
