    1996 GTS Gen2 MGW -v- OE Shifter Decision

    I guess the bottom line is that for the necessary "crowbar" that I want, it translates into the length of stroke of the shift knob. I don't know where the OE shifter fulcrum is, but assuming you could move it both up and down, that would allow this stroke to be achieved at different shifter...

    1996 GTS w/P0175 getting about 150 miles per tank of gas (was 300)

    Yeah, it was the VEC1 allright! When I suspected bad piercing connectors (installed around 1998), I decided to solder all the connectors at the ECU. The MAP signal wire which is cut and the VEC1 is "inserted," one of the crimp connectors FELL OFF THE WIRE! Over half the strands of the wire...

    1996 GTS Gen2 MGW -v- OE Shifter Decision

    Did it. Made a 2" threaded sleeve and a 1.5" threaded rod. The MGW is now 2" taller. Just drove it and LOVE it! Looks like I can't upload any more pics. Not clear what the rules are. Too bad, external hosting usually results in eventual loss. Bad for informative threads.

    Will all >GenII Vipers'' Tires/Wheels fit a Gen II?

    I was a notorious and very successfully sleeper (supercharged Studebaker Super Lark) back in the 70's. Since nothing will ever top that (getting beat by a Studebaker???? the Horror... the Horror...) I would never ever, ever consider street racing someone with my Viper (can't win even if you...

    Will all >GenII Vipers'' Tires/Wheels fit a Gen II?

    I was just checking some 19 sizes. First tire dealers have no Viper listings for 2013 and above. But found some 2014 specs: 295/30r18 and 355/30r19 I'm running 2000 sizes: 275/35r18 and 335/30r18 REARS: There are 345/30r19 and 355/30r19 which are 1.24 and 1.48" greater in diameter...

    Will all >GenII Vipers'' Tires/Wheels fit a Gen II?

    Will all >GenII Vipers' Tires/Wheels fit a Gen II? Looking for alternatives. And would love to be able to buy Kuhmo's too.

    CWhiteRun, A 99-02 shifter? Do you specifically mean use neither a 96-98 GTS nor a GEN 1?

    Tire Pressure & Handling

    I've wrestled with tire pressure and alignment for decades with regard to wear - nothing worse that burning the centers or insides and then not knowing how far off you are and how far you need to go to achieve the correct setting. You can do alignments, but there is no analytical method to...

    Fan Speed Relay: Always HI w/Trick Yellow "Jumper" Relay (trips P1489)

    Yeah, that's what the yellow "relay" does - it only has 2 male spades that do that. I have no idea what part number it is or who makes it.

    LTFT Long Term Fuel Trim -25/-28% w/VEC1 +4 LO +4 HI and NO DTC's = ???

    96 GTS heads, cam, headers, full exhaust. STFT's jump around -5% both banks (-2 to -9% spikes caught visually) Had to bump the VEC1 Hi to get good <12:1 A/F and bump the Lo to get rid of idle hang. I suspect the ECU was not tuned due to these codes. QUESTION: Anyone see any issues here that...

    DRBIII Fuel Injector Kill Test: Pass / Fail is... ???

    Did the test and from what I can gather, you have to visually average the fluctuating rpms as you select the injector to kill/test. I had some cylinders spike below 900 with an average in "low 900's" while other injectors spiked above 1000 with an average in the "mid to high" 900's. Obviously...

    1996 GTS High Idle (2500-3500) at high altitude (8000-9000 ft)

    UPDATE: DRBIII IAC WIGGLE TEST: Did this and the engine would jump from 1300 to 1900 every time the IAC was ramped open. Closing was fairly smooth. (No way to plot this information on DRB which really defeats the whole purpose of the test: inspection of the curve.) I suspect this could be...

    1996 GTS High Idle (2500-3500) at high altitude (8000-9000 ft)

    UPDATE: 9/10: Took to Mt. Rose 8900' 30*F and got a minor 1400 rpm idle hangafter shutting off at summit, then starting after about a 10 min "heatsoak." The hang occurred right after the cold start enrichment was over. One VEC1 click rich caused the hang to drop. (One click back cause the...

    What towels/rags to use?

    Can't recommend anything but I can say that I bot the most expensive, soft white bath towells they had at some high end department store and they were a complete disasterthey covered the car with white lint! (something I have NEVER seen happen with a cotton towel over the 45 years I've been...

    Fan Speed Relay: Always HI w/Trick Yellow "Jumper" Relay (trips P1489)

    I think this was a common trick much talked about around 2000 but couldn't find any search hits to confirm. (Think I learned about it at a Viper Days.) The purpose is that when the fan comes on, you ALWAYS get HI fan. Could someone confirm this? ___________________________________ This also...

    Gen II (GTS) OBDII Port Location?

    This is pathetic, I even found a pic of one and said, "That is easy" but I looked and looked and probed all over the place with my hands. I didn't realize the port is basically even with the bottom of the trim panel - I thought it was a few inches forward of where it actually is. So I got a...

    Gen II (GTS) OBDII Port Location?

    I'm thinking I have to remove the interior panel below the steering wheel to get at it but not sure.

    1996 GTS High Idle (2500-3500) at high altitude (8000-9000 ft)

    UPDATE: 9/6: With soldered VEC1, engine has been very stable and more HP - can now churn the tires in 1st. No incidents until just now - I took car to 6200 ' AND a little chilly 55*F (maybe even a few more degrees cooler), and the idle hanged around 1300-1500 rpm. Knowing that the VEC1 Low...

    Nitrous Bottle Size and Location to Allow Access to Spare Tire

    Actually, its not really about the spare - it's about where to put the flat tire w/wheel! I was thinking it may be possible to put an angled ("negative" camber from aft view) bottle bottom at the quarter panel and top at the hatch opening. I'm really only thinking about this because the car...

    Nitrous Bottle Size and Location to Allow Access to Spare Tire

    My 96 GTS (heads, cam, exhaust) had a bottle bolted to the spare tire cover (!) - I took that out as soon as I saw that. Seems everyone has one or two bottles inclined over the spare tire. So the only real option would be some kind of short, fat bottle to tuck by the fenders - perhaps two of...

    Hellcat versus Viper transmission

    The original concept of the Viper was to be the reincarnation of the Beast AC Cobra. Beast. Let me say that again... Beast. The Viper should always be 50% more HP than the Corvette maintaining the margin the 427 Cobra had over the Corvette back in the 60's. If the Corvette is 600hp, the...

    1996 GTS High Idle (2500-3500) at high altitude (8000-9000 ft)

    UPDATE: 9/3/2015: VEC1 MAP intercept wiring was FUBAR! Installation consists of cutting the MAP wire at the ECU harness, crimp blade terminals onto the ends, and then connect with terminals from the VEC1. The crimp terminal coming off the ridiculously short cut they decided to make at...

    1996 GTS Gen2 MGW -v- OE Shifter Decision

    Yeah, I once had this MGW 96 and a stock 2000 and I loved the stock one. Your MGW, was it just the arm? a simple change to the stock one?

    1996 GTS Gen2 MGW -v- OE Shifter Decision

    Previous owner installed the MGW parts: short arm shifter, console cover w/cup holder, and gas cap cover. and the valve stem caps. While a short shifter arm is cool, on a T56 I need more "crow bar" to bull past the totallyl inadequte single cone synchros. What are my options? I was...

    1996 GTS w/P0175 getting about 150 miles per tank of gas (was 300)

    I'm about to start diagnosing this today and my #1 suspect is a leaking injector O-ring.The first thing I'm going to do is inspect the spark plugs and see if there is evidence of a rich injector. I shut the engine down while presenting the 3000 rpm idle. Once I do that, I'm going to listen to...
