Default building motor now what turbo

so im just gonna build the 205 since im poor. gonna go through the bottom and do forged pistons rods.....you get the idea.

gonna go with a top mount sti intercooler i imagine but my question is if i only want 300 horse what turbo should i run and what injector.

i know everyone says ask your tuner....i dont have one sooooo another question is should i go with a higher compression piston on the 205? and then i could run lower boost. what are the advantages and draw backs of this. i know this will change quench but there has to be some give and take. i like the revier feel of a higher compression turbo motor.

also is it better to have a bigger turbo than necessary or is it really critical to hit it right in the sweet spot of its efficiency?

interested what you guys will have to say.
