Default Forget the supercharger, the torque converter etc...total engine rebuild?

In my constant dreaming im wondering if it would be easier to pull my engine and do a total rebuild with new seals/gaskets, pistons, cams, valves, etc etc etc. I read somewhere on here that a rebuild/buildup would take about 20 hours and I would love to do all this with the engine out. I'm looking to add a little more power but with 120k on the original engine i'd like to do it just for reliability and piece of mind.

EJ22 right now. Would it be cheaper/easier to do a ej25 swap? I dont want to fork over money for a new ECU etc. Could I get a used EJ22 smallblock cheap?

Should i just totally forget this idea? I would want to do it this spring after im done pissing money away on heating oil. Maybe take a week off and work at least 8hrs/day on it.

If you have some mechanical experience a full engine removal and rebuild should take less that a month and be well worth it. Take you heads to a good machine shop with a full factory gasket rebuild kit and make sure to tell them that you want all the unused parts. have them clean up the heads, replace all seals/ & press in new valve guides, maybe a port & polish, 3-5 angle valve job(depending on the shop reputation and your budget) rebuild/replace the short block(more money, less labor/ less chance of screwing something up, less labor intensive to just to replace the block) It's kinda fun to rebuild the engine and you can have some sense of pride while driving around. I rebuild my engine at 65K and couldn't be happier. I have 101K currently and just got 30.18 MPG on my last tank. Great throttle response and it's a blast to drive.
