I will sell my entire TB for $400 shipped, that way, you still have your original TB to do what you please with, and for some reason if you do not like the upgrade, you can always switch back to your 50. I just had this TB done by HPI in Febuary of 2011 and ran it on my 120R, and there is less than 1000 miles on it. I recently put a Trask Turbo on the 120R, so looking to upgrade to a HPI58.
IAF, fuel rail and line, and map sensor are NOT included. Not wait time and no core exchange. Like getting a stock TB for $50 and saving all the shipping. $400 shipped!!
