how much would you guestimate it would cost to take an H23A1 apart, clean it, put in all new bearings, re-ring the pistons, new honda factory valve train components minus the camshafts, reassembly, new oil and water pump, new clutch, etc. at a reputable shop? basically put the motor back to factory specs and take the mileage off more or less. this is assuming there is no excessive wear on the actual rotating assymbly components or the actual block or head itself.
Depends. Having a shop do it I'm not so sure. A local NTPOG'er just paid I think $1500 for an engine swap (labor). Not very cost effective in my book, considering he paid $3k for the motor. Even if you sourced your own motor, you could probably spend the same amount on labor and parts for a rebuild.
Even if it's a wash I would think you'd rather have the H22A, but that's just me. What I would be more concerned about is it being done properly, finding someone who knows how to hone a Honda motor and clearance the bearings. Your standard autozone plastigauge isn't really good enough for it, and if you're using that your stock bearings are probably just as well.
Well it is cheap to do the swap. It only cost me 1200$ engine, 215$ ecu and maby a MAX of 100$ on other stuff.
To rebuild an engine im sure that would cost you at least a few grand. But there is an upside to it. If its done right you KNOW your engine will run for a while unlike a JDM where you may drive on it for 6 months or so and then have it die. You never know if some punk Japanese kid owned it and never did an oil change. I would still go with the JDM just because VTEC rox.

a swap is cheap. tearing down an entire motor to replacing the rings and bearings and seals, honing the cylinders, putting it all back together again properly? that's going to cost several thousands of dollars. you are talking about days and days of labor, and a thousand bucks in parts by the time you're done (oil pump water pump rings head gasket other gaskets main seals head bolts rod bolts cap bolts timing belt balancer belt clutch springs yada yada yada yada)

What he said. Definately just get a new engine, either H23 (dont ask me where to find) or drop in the H22.
Depending on the age and if your engine needs a re-buidl you'd probably notice an increase in power all the way through with the H22. plus all that extra juice above 5k.
damn...maybe this guy just wants a really reliable oem h23 which may be able to add sentimental value to his aging g4 which he so loves. not everyone with a prelude is about speed. ask the 70 year old geezer around my way with the 2k ebp prelude with factory kit on his way to the seniors club @ speed limit.

uh yeah, i dont want a stinkin' H22! i mean, if i would have bought a prelude vtec, then sure fine...but i want an h23a that i know damn good and well wont screw up on me cuz i plan to run some nitrous, not a big shot or anything...but nevertheless, im quite the cautious person and i dont want to use nitrous on my motor as it is now with 121,509 miles. vtec is cool and awesome and all that ****, but i'd be wanting to hit vtec all the time..and i hate that "waiting for vtec to kick in" crap. i like how the h23 is powerful from the get go all the way up about the same. flat, broad power curve...wonderful thing. yes i understand the mechanics of vtec and i agree its by far more superior in power production, tuning capabilities, etc etc but i have an h23 and im not unhappy with it so why should i change it? plus, its cool when i beat cars that dont think they should get beat by a honda...then they say, well...you have vtec...and i say...no i dont. plain ol' run of the mill non vtec 4 banger just whooped your @$$. i dont know...this is all nebulous anyway as i have decided to make my car look better first before i do anymore performance-wise. ::
welp ... your lookin at some cash but do it right since its a part then. H23 is hella fun .. I love mine ..
But I think im going to straighten the curve out on an H22 when she goes.
Keep us updated on what you do. Call around your area or shop for other H23's with low k's .. i haven't see any but you must be able to get a JDM one somewhere .. .
