Would be easier and cheaper to swap the Beams lump out with a 3S-GTE.
The Beam's engine in all fairness has a compression ratio that is really too high to go bolting a turbo to on. It will work, but for how long is anyones guess.
If you really want to turbo this engine, I'd first replace the pistons with some of a lower compression ratio and replace the head gasket for one made of metal.
