It might work. The 4G64 on the 3G Eclipse's is not the same as the one in the 97-99 4G64 Spyder though. Everything is flipped around. The tranny is on the drivers side, the timingbelt is on the passenger side, the power steering pump is on the passenger side, the battery is on the drivers side, etc. Kinda like comparing the setup of the 4G63 in the EVO 8s to the one in the DSMs. The turbo would still be on the front of the motor, but the rest is like looking in a mirror. The cast manifold used on the Dougs Dynopower 4-cylinder 3G turbo kit sure does look like a 2G manifold in the tiny pic I found though. A T25 would be a bad turbo for a motor that size though. At the very least get a 14B.
