as people look to increase power my concern will be with reliability, at some point we'll have to build the internals
What's this we crap
Tonto!:grin: You all are going to have to buy one first and stop all the dreaming.!:grin:
The TCR is purpose built, with 350 whp more so at the crank ore likely around 425 crank horsepower. Pistons, cams, valves, port and polishing, balancing, race ECU etc. A standard or performance package N, will never be able to eclipse this kind of whp without a complete purposeful performance rebuild. And, you can nix the warranty all together.
350 whp for a built Subaru is tame, compared to many others of it's kind.
Blessings and Peace
