I'll say it just once. RS blocks do not like to be t/c'ed. They can run fine on a super low boost for awhile, but they just aren't meant for it. It's a lotta money and a lotta upkeep to make sure it runs decently.
Stock 2.5 has 165 hp, so don't forget how much of that you lose with the AWD driveline and differentials.
That is very helpful, thanks. So if turbo for this engine is not a good idea then what does it respond to best for modification?
