It's a 20+ year old compact, they didn't crash well brand new
Respectfully I'd like to see you live to swap it for something else
In fact, I dare you to take it in just to confuse the people on the service drive
They're used to swapping engine/transmission and subframes on mostly 2010+ vehicles
This cars probably older than the young porter kid that's pulling it around
A good few of the techs probably have never seen one
Show them a vehicle that
doesn't need an engine, they'll be baffled
As for the TB kit, I'd go with the Aisin TKK008 or the Continental PP302LK1, the latter includes cam & crank seals
