I'm running TD powertrail, ulmer primary spring, stm weights, stock secondary spring with a 35/39 dalton. I'm not sold on the reverse angle and feel there may be something better out there. In my SRX days we always ran 3 or 4 degrees higher than stock start to 3 or 4 degrees lower on finish. I...

So after rebuilding my sled after 3 years of it breaking (see my long list of threads on here if you want a good story) I found out that I may need new pistons. In a previous post I mentioned I did a compression test which came back 30, 30, 120, 30. Then used a bore scope to check if the valves...

Hey, I recently purchased an early model 240HP nytro turbo kit from a local dealer that had it left on its shelf. I am assuming its an earlier model because it comes with the external surge tank, brown injectors, 16T turbo (someone can correct me if I am wrong on this stuff). The only...

I got a great deal on a new MPI 190 kit on eBay for my 2014 viper xtx and I'm making sure I order everything I need for the install. I've read just about every turbo thread I can find on here but I just want to get a little advice. I'm new to turbos but I've worked on my sleds for years and...

So I have a 15 viper mtx with the mpi gen 2 turbo. I took it out the test it in my field and when I got back there was a lot of snow inside near the exhaust. Has anyone used the frogskin vents to stop this from happening?

Ive got a rx1 with a turbo kit on it. I also have a nytro without a turbo. Im just wondering if its possible to swap the turbo to the nytro? Rx1 isnt running anymore and would love to boost the nytro. Im a welder so any welding mods would be easy. Just wondering about fuel injected nytro carbed...

Hey all ! Im just wondering if its posible to put the turbo kit from my rx1 onto my nytro? I dropped a valve in the rx1 so im thinking why not swap if i can. Has this been done? Can i get away with modifying the intercooler or is there room under the tight hood. Any and all info will be very...
