If you think that is good, check out Howell Automotive. They make alot of high performance parts for Neons and PTs. They sell a 55mm T.B. for $299. After you install you new T.B., send back your old one and they will refund you back the core charge of $100.00 for boreing it out. I hade this done on my Neon, that's how I know.
