are you customizing your own turbo or getting a kit? the best one out there that i would recommend is the Revhard kit. upgrade wise, for fuel management, Hondata systems are very efficient. if you like full control of tuning your fuel setting and all other function, AEM makes a downloadable program on their unit. the problem with that is, there is really no way to find out if the car is properly tuned unlees it's on a dyno. on the ignition side of the house, hondata will also cover that. it sounds like i'm all about hondata systems, but there are other choices. i've heard great things about hondata systems and NO complains yet. while getting your car ready for a turbo set-up, i highly recommend that you get a cat-back system. the thermal R&D 3 inch system is probably the most common one. random tech makes a high flow cat also.
