Hey guys, my buddy has a 91 civic dx hatch & his motor is weak & smokin! What straight forward swaps or close to straight forward are there for his model, i'm used to dealing with the 92-95 obd1 stuff & just figured i'd ask because i'm not sure his motor is going to make it through the summer!

Thanks for any info..

i'm mainly curious about a b18a1 for it coz we have an extra one sittin here. lemme kno! thanks
