Im not exactly sure what you have to do to it. I think all you have to modify is takeing your parts off yours and installing them on the Jeeps TB. It wouldn't be hard but could be a disaster if you loose or break a part getting it apart. IMHO 60 mm is too big for a N/A 2.0. It would have more effect on a turbo motor. Anything over 55 mm is overkill if you ask me. Save yourself the trouble and buy a 55 mm bored ATX neon tb. I got mine for 120$ at Howell Automotive. It was reg 199$ but had a chip in the plastic cable holder.So I got it cheaper. And it works all the same! LOL.
The only time it will make any diff anyhow is at WOT. + you do realize that it means you will use more gas! More air = more gas. I used a dremel tool to port match my 55 mm to my intake plenum. Also used it to polish the tb. You can get a little more out of it if your intake and exhaust gaskets are port matched too.
The Jeep 60mmTB can be retrofit to a neon, but it does need to be modified. I dont know exactly what is involved, but browse around neons.org and i'm sure you can find your answer.
60mm TB is overkill if you are still running the stock intake manifold. You'd have to port it within an inch of its life to even come close to equalling the cfm the TB is capable of flowing. That 90 bend below the TB is a killer. If you plan to run an INDY manifold, then its a different story.... but without bigger cams the INDY is overkill too. Just my 2 cents, Good luck.
lol i wonder if the indy intake mani thats meant for the 1st gen dohc would fit on an srt-4 i was told the turbo mani off the srt-4 would fit on the 1st gen dohc not sure if ne truth to that but if the exhaust fits why wouldnt the intake lmfao! i wanna get a 60~~>55 ( necked tb ) for my srt-4 but there over priced on modernperformance...atleast n my opionon!
