Just a side note, the Apex'i kit is no longer available for resale because it's discontinued by Apex'i. If you can find a new one, it will probably bet going for close to retail (which is > $200).

The Greddy 92-95 kit can be used without problems, but the primary O2 sensor wiring needs to be extended. It comes with a 15G Mitsu turbo and maxes out in efficiency around 15psi.

The new kit for the 99-00 EX models has been released. WestCoast and myself are the only people I know of that can get these kits as of now. It comes with a 19T Mitsu turbo that's just larger than the 15G and should put out a lot more power and have a higher efficiency range, but I haven't been able to get a clear answer from Greddy on this. Someone dyno'd it and gained about 50whp at either 8 or 10psi.

The blue box that comes with the 92-95 kits can now be sent to Greddy and traded for a base-map E-Manage. The new kits come with the E-Manage and additional injectors.

These turbos have actuator style wastegates and boost can be adjusted by turning a nut on the actuator arm, but I highly suggest using an electronic boost controller so that you don't run into boost spike. An EBC will also ensure that your boost level stays the same throughout the RPM range.

Let us know if you have any other questions! SOHC POWER!!!
