Came across a couple sets of new JM Stage 3 heads for the 03-06 Viper.
These heads are CNC ported with stainless valves, Phos/Bronze valve guides, Viton valve seals, ductle iron valve seats and performance valve springs and retainers. Combustion chambers are reshaped and matched for 10.0 to 1...
The best place for the 02 sensor is at the turn out, where all 5 cylinders come together. The sensor was relocated from the turn out, to one tube in the Belanger headers in 2000. People were getting check engine lights for "O2 sensor heater" when the O2 sensor was placed in the turn out. The...
Yes it is common with the 03-06 models. There is a strap welded on the back of the exhaust manifold that keeps the tubes aligned, the manifold cracks where the strap meets a tube. I have found if you weld them up it does not happen again. If you replace with new you might be back in the same...
If the car had more power, better brakes and a paddle shift transmission at a price that would allow current owners to move up. It would be golden. I have had numerous owners that have stepped into the new Viper every generation, but gawked when they would have to come up with 70-90 grand to...
Its often tempting to get the lower stance a 1 inch drop will provide, but on a Viper with 17 inch wheels its just too low for the street. The car wont make it out of driveways without scraping and speed bumps are torture. You end up driving the car slower as you are worried about bottoming out...
We torque those bearings to 250 on the street cars and 300 on the race cars. More than the factory spec. Most likely the noise is play in the snub-axle splines at the wheel. We swap right to left wheel bearings, which switches the pitch of the splines in the hub and gets rid of the noise.
I have driven and worked on numerous Gen 5's, they are great cars. The issues I have seen are minor and often get resolved properly.
Even with some bad press, which is often one sided or reflected by poorly performing abused press cars. This is one amazing car.
For those looking for...
Its a good package, but as a bolt on the same or better gains can be had with modified Gen 3 parts. If you want that package to make real power (I agree with MJ), port the G4 heads and intake, raise the compression 2 tenths of a point, run a little bigger cam, headers and have it custom tuned...
This is a great thread about a custom build, it is what this site is about, our shared passion for these cars. People get excited about this stuff. Heck we only live once, its nice to have a place to talk about it. Seems comments like this kill the whole purpose of participating on the site.
My...
This is really a great project, how often do you get a chance to work directly with factory vendors to build a one of a kind car. For those who don't know Bill he has been helping new Viper owners for numerous years. Even though he is in Nebraska, his network expands around the state. Don't be...
Odds are you have a voltage drop issue or that new battery is defective. Have the alternator tested with a load tester to see actual output. Do you have a smaller crank pulley? Many race spec cars change this and it will not charge enough at low speeds. If it is a computer issue, it would not...
I would be happy to help you with this. Glen Thomas is a local dealer to me. I am sure they would help if I had an issue fixing this. It takes a bit of time to properly align these windows, I worked on this quite a bit on the Gen 4's and am sure that it bleeds over.
Not all dealers are the same and SRT has worked hard to get well trained, responsable service people on board. Do some homework and make a connection with someone at the dealer, you might be suprised. The SRT dealers I have dealt with in California have been great.
This looks like a battery problem. Charge the battery and have it checked. Just had a 2013 that had a bad battery from sitting too long. Even new batteries can go bad if they sit partially discharged for too long. When a battery discharges the acid moves out of the plates, if it is not absorbed...
Hey Dave,
The 08-10 side exhaust systems sell for $400-$600 typically. They offer less heat; better sound and a 5-peak hp gain on the 03-06 models.
There are numerous options for a cat back system. The Gen 4 (08-10) model differs from the Gen 3 and many Viper owners do not understand the...
I worked with AEM on the first stand alone systems for the Viper, I provided them with the first development car a 96 GTS. We did have a bunch of issues at first, a hardware change was needed to add an additional ground for the wideband sensors and there were some software updates, but after all...
You need to do an idle relearn, hold the pedal until the idle catches then let it idle for five minutes, then turn on the AC and let it idle for 5 minutes. That allows the computer to relearn the idle.
The 96 GTS dipsticks had a red ring around the top that went over the dipstick tube. These did not seal well and often popped out with crankcase pressure. As VPA stated they superseded number was the fix. Dealers are often confused with 96 Vipers as they had two generations that year.
One thing that many folks miss when lowering the car is the proper loading of the suspension bushings. When a car is lowered, the upper and lower control arm bushing mounts must be untightened to let the car settle to the proper ride height, if you lower the car and do not do this then the...
