I've had my +12 for over 1.5 years now and running on 5 gallons of Mugen 30% or O donnel 30% running at race temps of 230f to 269f depending on performance for the day....
I just checked the rod and the top of the piston and everything is o.k.


I've been running the skyline pipe with a nova/medium conical header with decent performance...

I just bought the nova 2630 pipe so I'll let you guys know what the differences are....
