I have a 2003 dodge neon r/t, i have just added a hahn turbo kit to it. It had 120 whp and now it has 215 whp. I am running about 9 to 10 lbs of boost with a boost controller and have had it professionally tuned. I was just wondering what other performance parts i could add to increase the horsepower without blowing the car up. The whole engine is stock and dont know how much deep i want to get into this (by taking the engine out and rebuilding the whole engine with stronger pieces). The exhaust is 2.5 inch diameter, and the high performance ones are only 3 inches, so it would make only a small difference. Any ideas on parts? Thanks.
