I would stay away from air intake chips chips however, they do have the potential to severly damage your vehicle. They alter a signal and cause the computer to belive that the incoming air is denser than it really is. By converters do you mean catalytic converters? Most of the alleged "High Flow" catalytic converters I have seen are too small to be considered high flow on a vehicle of this size. What I did on mine was installed a Hermoff Heavy duty converter. I was able to use just one in the position of the origianl rear converter. It was larger than the original, and rated up to a 10,000 lbs vehicle. Not only did it get the heat away from the transmission modulator, but it outperformes the origianl design. I am useing a 2.25" pipe from the y-pipe back. I had the y pipe redesigned. That is where most of the restriction in the original design was found. Don't increase the size of the exhaust beyond 2.25 in, because if you do, the exhaust gases will move too slowly to scavenge, and you will loose power and efficiency. This is the biggest mistake many people make with performance.
In the US, running without a muffler is illegal. So is running without a cat, though it is not enforced in all areas. I have never seen a vehicle actually run better without a cat. We dyno tested a vehicle without a cat versus a stock vehicle, and yes its peak HP output was greater, but its overall performance was actually diminished. The removal of the cats was the only difference. The stock vehicle won in races versus the catless model every time. The only was to make the catless vehicle win was to make further modificatons. The factory vehicle just had more torque. The onl situations where this would not be true, is if the original converter was plugged, rattled loose, or the old bead type. In the first two cases, something was broken or not functioning correctly. In the third case, bead type converters are very restrictive in comparision to the modern honeycomb substrate.
i am trying to find a good high pereformance ((((TORQUE CONVERTER)))) and (SHIFT KIT)... and i would also like to install a performance chip and possibly a throttle body spacer
Are you trying to extract the most gas mileage out of the van, or are you trying to extract the most power out of the engine?
If you are thinking power, I would recommend against it. First of all, you might be violating Federal emission laws (I'm not preaching, seriously). Second, the tranny is only adequate for these vans, and these are pretty heavy vans. I don't think you'll ever make rockets out of them, but you are going to mess up the drive train in the process.
Just my 2 cents worth of advice. It's free so take it for whatever it's worth
try a google on Ranger engine performance parts..these engines are commonly hot rodded in Ranger forums
put in a 5 speed manual if you want any tranny longvity and reliablity...the Aero auto will not take any hot rodding...originally designed for 80 hp engine
you would pretty much need to do a full engine/tranny swap, with a Ranger most likely. Other than that you would need to customize almost anything you want.
If you go the swap route, i'm in need of a new engine and tranny since mine gave up.
As far as performance chips go, Ford EEC-IV computers are not that difficult to mod, you get the chips with the program you want and swap them out. However, unless you have and electronically controlled transmission, you cna rule out the shift kit, since the computer does not control the shifting itself. It controls the valves and solenoids, but the shifting is still governed by a vacuum actuator modulator.
No it isn't. Running a car that's above an acceptible noise level is illegal, sure, but how you get there isn't as specific. The Dodge Neon SRT4 didn't even have mufflers from the factory, but they were 50 state legal. Of course, as you said, a lot of jurisdictions are a bit lax in enforcing such things as well...
According to the legalities, there must be at least one sound suppresing device. They may not have had mufflers, maybe they were just resonators. They wouldn't deaden sound much, but they would prevent the deafening raw engine sound.
