The DRAG 3's had a filter, I believe it was an Airnix, or a K&N wannabe....am I mistaken, or is the intake a cold-air on this kit? That was a major problem with the DRAG 3's, the intake was about 6 inches from the cast iron manifold...the turbo already super-heats the air. Intercoolers can only do so much. A good run on a DRAG 3 kit was before it was warmed up, or in freezing temps. This kit looks like one of the cleanest aftermarket kits I have seen, did they do injectors? What are you doing about timing and fuel?
