I have a '91 integra ls, and I am thinking about an engine swap. I want to keep the car, but the stock engine (B18A1) has 190,000 miles on it, and starting to really slow down. I was wondering how hard it would be to swap it out for a gs-r engine or a prelude engine. Any help/advice is appreciated. thanks

 

I have the same car as u do my frend Ive had a B17 blew it.B18a1 i spun a bering or shoudl i say rod berings now i have a B16 and i'm back i VTEC again.I woudl no do the H22 or the prelude motor as u say.
