put a turbo or super charger on a 4 cyl?

My buddy did a Turbo on his 4 cylinder , now wants to do twin turbo , forged pistons and rods . He also picked up a 6 speed to swap in ... He has lots of spare time and $$$$
I personally enjoy my truck for what it is ... fuel efficient and reliable in stock form .

 

Tell him, a compound turbo setup would be best for his 4 banger!

 

If you paid credence to @MrCrowntown 's earlier post about the block being identical to the 3rz, and you were knowledgable of that engine, you'd quickly have realized its potential, and wouldn't have posted anything other than praise. As it and the 3rz are both superior to the 1GR. Cheaper to build, proven for the past 2 decades, and more power potential. 2TR is just a VVT 3rz.
