was wondering if a d15b vtec can be put into a 1991 civic hb si with little to no mods? and if there has to be work done as far as changing out parts, what might they be? found one for sale with 87,000 for four hundred. considering that the engine is good, is this a good swap. mine is a stock 1.5L with 196,000 with some issues.

any comments would be appreciated
