No offense meant, but spending alot on an N/A is pointless! You can get 7M-GTE's (JDM motors) for fairly cheap, and with virtually no mods, other than turning the boost up a little, blow the freakin' doors off an N/A! You still have the sound, and torquey feel of the 7M, just with larger balls! The sky is the limit on HP with the GTE, whereas, the N/A is very expensive to take past 250whp. I've spent less than $5000, and I'm up around 350whp! Why stay N/A?! Once you experience boost above 12psi, you'll ask yourself why you ever spent one penny on normal aspiration!...Trust me, I was there!
