Cost wise, just get another long block. You should be able to get a S14 engine for $1k if you know the right people.

If you want it done right, rebuild the whole bottom end with fresh goodies as long as the crank isnt fucked. Again you wont know till you start disassembling the engine. Repolish/balance the crank, get some Eagle Rods, Arias 87mm pistons, fresh bearings and hone out block. Hopefully the heads not completely junked, if the heads not completely warped, might get away with decking it. Hopefully the head components are not fucked like valves, guides, cams, lifters, etc. Itll cost a pretty penyy but atleast you know itll be done right. If you can do all the work yourself and have hook up with machining, you just gotta buy the parts and hopefully have some guidance as far as rebuilding it.
