ive long been researching this question because i am planning on swapping either a gsr engine or type r one. i am planning to put a stage 3 revhard turbo kit. i heard that the type r engine wasnt a very good motor for a turbo application because of its high compression and that the gsr would be a better choice and that it would be even better if i just upgraded the internals either with type r ones or any other manufacturer, leaving the compression alone. Is this true?
