99% sure it's the same. But that's an assumption!
Me too but I'm curious about the different compressor housing if it makes it longer or shorter than the 4094 as this will require piping changes. My 464 is a 5" inlet/4" exhaust so it requires alot more work to make fit with the kit. Depending on Mark's opinion for a twin setup this may be an option to get me back in a VVT. I really would like having the exhaust brake again. I tow a fair bit.
