M5,
You have this exactly right. Most times guy's are trying to use junkyard or backyard DIY turbo setups that are sized wrong and end up with: too much boost, excessive back pressure, short lived turbos and the list goes on. Forgot the emptier wallet.
Just trying to make sure it goes right the first time. Most guys only want 5-10 PSI for street use. This will really wake up a engine. Tom
If you select a turbo that is too small specifically the A/R is too small it can spin up so fast that it basically over revs and goes way off the compressor map. You end up with poor performance, lots and lots of heat and short turbo life. Thats my guess as to what he meant but I could be misunderstanding as well.
