As excited as i was to do this mod , i've decided to sell my 1ZZ TB. I've tried everything under the sun to keep it from causing a CEL. I've only had it on my car for 2 weeks. It is a great mod for midrange and top end. Sounds incredible with an intake. I've just decided that i like the idea of not having a CEL. I'm just anal i guess. The rivets have already been drilled out so all you have to is drill the rivets out of your 1NZ-FE TB and swap your 1NZ chip over to the 1ZZ TB. I will still include the 1ZZ TB chip as well. This will throw CEL, there are some members on here that have this on their cars with no CEL. How they did this i have no idea. This TB will cause a high idle at cold start and a little oscillation. TB will be pulled off car on 03/31/2009 and be available for shipping 04/01/2009. Good luck and hopefully you have better luck than i did
Asking $50 shipped
