The Drag kit is alright as a starting point.
To get it to run nicely, you'll want to ditch the rising-rate fuel pressure regulator. Get yourself a set of 440 cc/min fuel injectors and a Hondata ECU, have everything tuned and enjoy a much higher level of reliability.
The wastegate that comes in the kit is crap. A good manual boost controller will give you quicker spool times and a more stable maximum boost level.
The downpipe on the kit comes without a flange on it, you have to take it to a muffler shop to have one welded on to match whatever catalytic converter you decide to use. I would reccomend getting a Carsound 3" piece. You also want to have a 3" exhaust, Thermal R&D makes a nice one.
So.
