Has anyone seen the castrol topshop contest?
Long story short...
Some shop building a sr20det redtop said they can build sr's to 11,000 redline he was insisting on cp pistons,high duration cams,solid lifters,ect.But for the bottom end besides cp pistons it was xbeam rods,sleeved,bored to 90 i believe.
IDK if that helps at all.
