Hybrid Racing RBC RWD Coolant Port Adapter - K20Z3 / K24A / K24Z
type: Product
description: Anyone who's put a K-series into a rear-wheel-drive chassis knows the problem: the firewall is right there. The standard coolant housing exits out the side of the head, and in a tight RWD bay that's exactly the wrong direction. This adapter fixes it by routing the coolant outlet straight off the back of the cylinder head instead, which is a much smarter path when you're fighting for every millimeter behind the motor. It's compact, it's machined from a single piece of 6061, and it turns a packaging headache into a clean, sensible cooling layout. Read This First: Manifold Compatibility This is the most important thing on the page, so don't skip it. Because the coolant outlet exits from the rear of the cylinder head, this adapter is not compatible with standard transverse K-series intake manifolds, and that includes the factory PRB, RBC, and RRC manifolds. There simply isn't clearance behind the head with those manifolds in place. This is built for use with rear-wheel-drive-specific intake manifolds that leave room behind the cylinder head. So confirm what manifold you're running, or planning to run, before you order. If you're still on a factory transverse manifold, this isn't your adapter yet, and if your RWD build is running the standard side-exit setup, our FWD RBC coolant housing adapter is the one you want. Built For Tight RWD Engine Bays The rear-exit design is the whole reason this part exists. In an S2000, a BRZ, a BMW, or any other RWD chassis taking a K-series, the space between the back of the head and the firewall is at a premium, and a side-exit housing eats into it while forcing your hoses on an awkward detour. Pulling the outlet straight off the back gives you a shorter, more direct path to the radiator and frees up room you genuinely need for everything else back there. It's a smaller footprint doing a better job, which is exactly what a tight swap calls for. Keep Your Heater Or Do A Clean Heater Delete You get both options in the box, so you decide wi…
