My younger brother recently received an '89 Civic hatchback as his first car (he's 16). My main question is this. What's the best option for an engine swap? I see that the B17c5 puts out 195 HP and has an LSD(4th-Gen-Civic.com- Engine Swaps). I like the idea of this engine, but I can't seem to find one online for sale. Also, what are other common/easy upgrades that can be done to this model? Is there a disk brake swap for the rear drums? Can upholstery/interior kits be purchased? Thanks in advance!
