cheaper and less headache to just junk the current car and look for another with a good powertrain

Because a quality 90-93 JDM will cost $1,000 + shipping, new chain guides , new knock sensors and harness and all new hoses, water pump front and rear mains , new motor mounts will add $1,500, then $2,000 in swap and internal rehab labor.A quality job designed to last 100k+ will cost you $4500.If you spend less upfront but more in the long run if you skip any of the above.

the 94-96 will require creative harness redesign, and 97-01 have starter on wrong side and a dozen other problems in fittting to transmission and motor mounts etc etc a real nightmare. new ecu harness .

My 90 engine has 317,000 miles with as buit everything except new guides done in 1997 at 100k................what did you do to trash yours.

Usual cause other than guide failure is not doing 16 years x 4 oil changes!
