what engine swaps can i do to a 90 honda accord with out having to do any modification

 

h22. those cars arnt tanks like the 94 ive got so an h22 in that car could be a good time.

 

there is a lil grinding on a mount and axle nuts if you use prelude axles but if you you use the accord axles then you only have to grind a lil on the driverside mount

 

Without any modifications at all? Nothing.

How about a relatively easy swap? You can start by scrolling down in the Guide to Basic Accords and reading about the swap there, or you can try searching... This gets covered everyday.
