I feel you'll be in the realm of 'diminishing gains' if you try to turbo a 22re without significantly changing things, with regards to a 22rte in comparison.
In particular the fuel management. Rumor has it that the 22re can deal with approximately 3-5 psi boost without mods, however that also will require adjusting the timing (retarding it) to prevent significant detonation (since the 22re ECU is not programmed to deal with boost/timing requirements), which will put you almost on par with a 22rte with regards to 'off-idle' performance, and consequently will not provide the same peak power a 22rte would.

keep in mind the 22rte ECU is programmed with the turbo in mind, and the 22re ECU is not. So given the higher compression ratio in the 22re and having to retard the timing to prevent detonation, you end up in a "net-zero-gain" situation, where either one performs approximately as well as the other in most situations.

just a thought....
