    Motor's burning oil...time for a rebuild!

    Last monday my motor started burning oil so I did the only logical thing I could do. I found a 93 Accord EX with no title from a police auction for $350 and yanked the motor and 5 speed tranny out of that. So now it's time to get it rebuilt and put in my car. I assume I need to strip the block and head about as bare as they can go before getting it rebuilt, but I have some questions first

    The first thing is, what are some "cheap" ways to get a little more power or reliability while the motor is being rebuilt? I was thinking of either getting the head decked or the block decked to raise compression, or just getting higher compression pistons to add power by raising the car to something like 10:1. But then a shop told me that my options with that would be limited because the motor is an interference motor, so I was wondering if anyone has an opinion on whether to raise the compression and lose some ability to play with the cam timing, or if the ability to play with the timing might be more valuable? And if I do raise the compression would it be best to use higher compression cast pistons, deck the head or block, or use oversized valves? I don't wanna spend the money on all forged pistons and rods though. But what would be a reasonable compression ratio to put it up to, and where could I get the parts for it/what brand should I use? I can get 92 octane at most of the places near me so I could get it up to maybe 11:1 if that's safe? I don't have experience with interference motors so that's why I'm asking

    For head work I was considering adding a Bisi stage 1 NA cam and getting a port/polish job done on it. Does this sound reasonable for head work to get decent power or would you recommend doing a little bit more for a bit more power?

    For the tranny I'm just gonna run an OEM style clutch I *think* but a lightweight flywheel. Not sure if anyone can recommend a clutch that'd be good for daily driving other than OEM style, I want something that'll just last a long time and be easy to use since I'm not too used to driving 5 speed.

    Thanks!

    Stage two cam, head work, leave the block alone so you can still run 87. get a tune, h23 intake manifold, a good exhaust manifold and exhaust system and you'll probably be putting down around or above H22 numbers
    wat?

      what kind of head work would you recommend? Port, polish, valve job, titanium springs and retainers? Already got a JDM h23 vtec intake manifold plenum with f22a6 runners and EGR, IACV, and FITV delete. What kinda exhaust setup would you recommend? I'd rather not spend the $1300 on the bisi header if something else would do more since I have the car apart anyway. I have a 2.5" exhaust with some kinda ebay headers only.

      Edit: 89 is readily available anywhere near me for the same price as 87 or a penny more. But I don't know if raising compression is worth it. I've heard the HP gains will be small but that it could give a decent boost to torque. If not, screw that and what would be reasonable for head work?

      Edit again: I ordered a stage 2 NA bisi cam. Should I add on the valve springs and retainers or just valve springs or might I be safe on stock springs?
