Comparing the 2 motors in stock form + bolt-ons the TD04'd EJ20G @ just 10-12psi was WAY stronger than the ej22t @ similar boost levels.
The ej22t did have a little more torque below 2800-3000 rpm than the EJ20G, but once you hit that rpm # on the EJ20G it would just take off with MUCH better mid-high RPM power/torque
Car was equipped with the same
FMIC
Ported Airbox / K&N Filter / homemade MRT style resonator delete
3" TBE
Diamond coil pack
Walbro Fuel pump
Aeromotive FPR
Tranny Cooler
ECU/Sensors
on both motors (I have the EJ20G running off the ej22t ecu)
With the 16G on the 2.0 the mid to topend is improved even more & the pull is pretty strong.
I plan on tracking this car fairly regularly next season with a target time of 14.99 for bracket racing which should be easy to run with about 10psi on the TD05.
I also want to see what time it could post with a modified Torque converter & v-body + 18psi (which are my next mods for this car) - I'd estimate a very low 13.
I like the EJ20G sooo much that my plans for a dohc hybird ej22t are now scrapped & a V2 STi RA EJ20G (forged pistons + ported heads + better cams / valvetrain all stock) is in the garage waiting for installation in the SS when the GF8 EJ20G blows - the SS will stay 2.0 from now on!
Here are some comparison pics of the td04 vs the TDO5 & FMIC pics on the ej22t & EJ20G.
