For me even tho I figured this out I still want to push the limited of the delta before I ever decide to switch to the sigma, rn im working on a turbo build on stock internals going to push the limits of stock internals then fully build a 2.7l and see how far i can push it, will do forged sleeves and allwhat trans/ drive train are you using?
Me too! I've been sifting through the boards for a while now, trying to figure out a way to condense some of the info we have. And trying to find some local shops to get some "performance parts" made. Mostly jus porting and polishing intake manifolds, and a few custom pieces. imagine if someone could get the stage iv made for purchase on the regular?
