That is me.
Thats what happens when you put rb26 cams into an rb20 with stock cam gears/timing. It works, but not well, I lost all idle quality, and most of my low end, with the only gain being 6500rpm+ It can be made to work with adjustable gears. Overlap is not good, it is good in NA motors when both valves are open because the intake charge pressure coming into the cylinder helps scavange exhaust gasses out at a faster rate. In a turbo car, there is too much intake charge pressure anyway, and the intake charge blows out the exhaust valve under excessive overlap.
I could talk about cams all day long, wish I had the time to explain.
Honestly I think you'd benefit greatly just from gears, and if its the ****ty idle you want, gears are a ****load cheaper than cams.
