The only price I had ever seen for a twin plug setup was that $15000 setup on ebay. For $3000 a twin plug setup might seem doable in the future (after I add a 3.0SC with turbokit). Having twin plug alone on a 2.4 wont get much, and have to take the engine apart and buy new parts to upgrade the engine can be ÜBER costly. Its alot more bang for the buck to buy a 3.6. Besides, a chip and exhaust will put them at 290+ hp correct?
