R's have What ?
Hi, VolvoGoteborg , Hey that Triple K , as it suppose to be referred to is just a Larger KO4 Hybrid , sort of speak . Isn't Polestar running a Non Ford Exhaust Header for the Turbo , they were a little vague on those Details ?
Also , I pretty Sure the RS Pistons are Designed with Larger Valve Pocket & Full Floating Pins , as the Cams were designed to match this turbo setup .
Compression is 8:5-1
