Well, I don't know how much a Eldebrock TB is, but I would think its not worth paying over $300-$400 for a 65mm TB, If you want a 65mm TB just send it to Maxbore.com, the guy does them for $100, he has mine off my JDM B16a right now!! Everytime I read about people installing bigger TB, they say they get better throttle response, so I'm looking forward to that. And the $100 is way worth it, because even if you just have a i/h/e now, you might boost later or go NA and it will be already done. Thats the way I look at it!!!
