Advantages:
-Turbo friendly pistons (compression ratio, design).
-Oil squirters. They squirt the bottom of the piston to prevent detonation, and on a factory CAST piston, detonation will take your shit out quickly. There are also squirters in the rods to coat your cylinder walls.
-Since I have never ripped apart and checked a N/T block, I wouldn't know, I know that the blocks are very common, but I do not have one here infront of me to point out differences.

Its not about tuning. Street cars, or not perfectly tuned vehicles need all the help they can get in keeping shit cool, especially when using a somewhat fragile cast piston. Yes the 4g63 can handle a ton of power with factory components, you hear about it everday. You hear about that one guy that did "xxx" power on "xxx" setup. Do you want to know what I SEE everyday?
Blown motors from people thinking that they can make that same power out of it. (Yes the motors can handle a lot of power, but only in the right hands. You never hear about the failures.) Blown ranges from headgaskets to cracked pistons (ringlands usually), to jumped timing belts, etc.

Yes you have lower oil pressure when they are squirting, but their are ways around that.

The only person who has done it and documented it is doing fine with 330whp, which is more than I plan on making until I do nitrous.
And yes, you are in a community that does things ghetto. And I'm sure EVERY single one of you is guilty of it at some point in the time you have driven cars.

Yes, this community is filled with
new members asking stupid questions and doing ghetto stuff. Its called a learning curve. Everyone has done something in one point or another that someone else can consider ghetto, it just depends upon where you are in the "newb" chain. Its not always about following hearsay, but doing stuff that makes sense. If you want to waste your time (which it would be to me, my time is very precious) go right ahead. Go do a write up on it and submit it to Allan. I would be curious as to your results. I can tell you that I have EXTENSIVE research and development, let alone hands on experience, with the 4g63, and I am saying you are wasting your time. There are much better solutions out there.

In theory with smaller rings, smaller/thinner lands/rings sitting higher in block it *IS* a recipe for disaster, but whats a cracked ring land going to do? Oh no, it burns oil, time to go throw in the now done Turbo Shortblock. A whole nother 150 dollars, damn.

Hmm..cracked ring land? Dead motor. No compression (or low), oil burning, etc.
What happens when it takes out your head as well?
Or shit gets into your oiling system and takes out your new turbo?
Why do things twice?

Go for it, let us know. Best of luck.
