    So I am currently building a K24/K20 engine and ran into a slight snag. I am between a Stock RBC JDM intake or an Skunk2 Ultra Street Intake Manifold. The issue I am having is with the throttle body, I had picked out a Skunk2 74mm one but I noticed it is drive by cable. Is there a way to...

    Hello Guys, I'm new to the K-series but I've been reading a lot regarding cams. However I couldn't find anyone who has used CatCams on a k20/k24. I'm looking at their let's say drop in cam which doesn't require valvetrain upgrade. They are quite a bit long longer in duration compared to the...

    So I have a k24a2 I'm building. My plan is to push right around 500whp. I'm debating on what to do about the sleeves; should I just get a sleeve guard, should I get CSS, should I just sleeve it, or I've seen people use epoxy resin but not sure how much hp that can handle. Keep in mind I'm trying...
