The shortblock swap is pretty straightfoward, you keep your wrx ecu. You can use thicker headgaskets to keep compression where you want. Id suggest going with cometic ones. Id shop for a bigger turbo, injectors, and engine management as the 2.5l will own your stock turbo.

Puedo hablar un poquito. Hay mucha gente aqui se pueden hablar espanol mucho mejor de yo si no puedo explicar parte de tus preguntas.

Para tener lo mismo compresion, se puede usar el 2.5 block con pistons differentes o un gasket de cabeza (?) mas ancho de OEM.
Habla con Bigvalley auto en Puerto Rico: www.bigvalleyauto.com. Ellos usan blocks de Crawford Performance.
