Weasly2k, Enthalpy, I agree with pretty much everything you have said. The 5sfte setup puts you in the same boat as guys who put a t3/t4 on their 3sgte and unplug the map sensor to get that extra boost. You are totally relying on the boost controller and waste gate to do their job. If something fails then you have a problem. Is it ghetto? Hell yeah.
Blackbob makes a good point though that more and more people are trying to turbo their 5sfes. Most I have seen lately are teenagers who have friends who have done it on their cars or have seen others do it on the internet. Most of them can barely afford to buy the turbo kit much less an SMT6 or EMS and pay someone to tune it. They will find a source for information whether it is accurate or not and do it anyway.
