Here's the deal....first off ditch the Greddy. The guys I run with have all gotten better results with their Turbonetics T3/T04E set up. Every EX that they have done has put at least 200HP to the wheels running 8 PSI of boost. All this was done on stock internals no additional fuel system mods. except an FMU. As far as completing the turbo you defintely want to get a boost controller, turbo timer, and an oil cooler. Don't get the hondata unit for tuning. Go with TEC3, Apex'i Power FC, or AEM. All those units have better tuning capabilites. If you then decide to get serious about raising boost you're going to have to do some serious internal mods, esp. the rods, and beef up the fuel sys. with a fuel rail, regulator, pump, and injectors. And I wouldn't bother wasting the money on an OBDII to OBDI conversion. OBDII can handle the turbo if it's tuned right.

And for the Header comment....that almost as funny as the Mustang GTR Spec. Ed. that had a rotary engine w/pistons. God love the guys at Teckademics.
