Who is running a car with the coolant line disconnected?
Tuned this RB26 in an S13. Twin TO4E 50 trims. The most annoying part was dialing in the camshafts on the dyno.
Bottom end was built. We thought it could do more but the wastegate(s) gave out around 26psi.
I also fabricated (via tungsten inert gas welder) the intake pipes.
