Wrx Sti
how much would labor cost for installing upgraded internals on wrx sti?
wondering how much it would cost for new internals on wrx sti and how much it would cost to have them installed so that I can put a bigger turbo in the future.
How big a turbo are you looking to go with? A stock STI engine can handle up to about 400WHP with a good tune for quite a while. And that's more power than 99% of the people out there can take full advantage of. Something like 350 with a 20G or something similar is easy on the engine if the tune is good. If you still want to upgrade, it depends on how much of the internals you want to change. Really, the pistons are about the only thing you need to change for a good upgrade. So something like $600 for some CP or Mahle forged pistons, $200 for some new bearings, $200 for new gaskets and other things that might need to be replaces, and then probably another $2000 for the removal, machining, build and replacing of the engine. Or you could buy a built short block for about $2500 from some place like Raw1 Performance or Crawford and then maybe $1000 for the removal and replacement of the short block. But it will vary from shop to shop so I would contact a reputable tuner near you, talk to him about what you are trying to accomplish and go from there.
