When Paul Bestbier from @ndtracing approached us late last year, the objective was clear: provide a 2L NA K20 that could handle the rigors of endurance racing after they’d been let down by other engine builders.
We supplied our flagship K20R—our top-spec 2L K-Series capable of over 300BHP NA (UK DIN-Correction).
The engine was destined for @racing_spiritsa Ligier JS53 Evo 2. While endurance racing is the ultimate goal, the team targeted the 2026 Simola Hillclimb “King of the Hill” for its first competitive shakedown.
Due to the tight build schedule once the engine arrived in South Africa, the K20R was still running a standard RRC inlet and a standard Ligier exhaust system.
This event was always meant to be a shakedown, with any result considered a bonus. To walk away with a Class Victory and an incredible lap time is a testament to the driving of @connorkilbride_@racing_spiritsa and the raw potential of the K20R straight out of the crate.
The next phase for this K20R engine includes fitting @atpowerthrottles throttle bodies and a full custom Bourne HPP exhaust system that we provided.
We’re incredibly excited to see what this car can do once it’s fully unleashed. Congratulations to the whole NDT Racing team, Connor, Paul, and all those involved!

Our expert engine builders make it look so simple 👏
Watch as Chris assembles this Bourne HPP Honda K20 Cylinder Head, featuring full Be-Cu (Beryllium Copper) upgrades for ultimate valvetrain stability.
The K-Series has been a staple for two decades, but we’re now seeing the limits of these castings. After 20 years of abuse, we’re finding many of these heads have sunk. The factory seat geometry is fatigued and the integrity is gone, you can’t just throw new valves in and expect it to live at 9,000 RPM.
By installing Be-Cu seats, we’re solving the problem at the source. The thermal conductivity is far superior to steel, pulling heat away from the valves faster and providing the impact resistance needed to stop seat recession in its tracks.
The Bourne HPP Standard:
Every part is lined up and verified before assembly. If the prep isn’t right, the build isn’t right.
We don’t just replace parts, we restore the geometry to ensure the head is better than the day it left the factory.
Engineering the valvetrain to survive another 20 years of hard use.

The ultimate valvetrain upgrade? 🧐
Through our engine expertise at Bourne HPP, we have found that after 20+ years of heat cycles, original valve seats often begin to sink. This is especially common when you add aggressive cams and upgraded valves into the mix.
Head over to our blog to read the full technical breakdown on how we bulletproof our cylinder heads for ultimate track reliability.
✅ Now available at bournehpp.com for K20, K24 and F20C, other cylinder heads available upon request.

You asked for a foundation you can trust to build on at home. We delivered 👇
We know the feeling. It’s 2 AM in the garage and the most stressful part of the build isn’t the assembly, it’s the math.
Did the machine shop get the tolerances right? Is the crank balanced for the RPM you’re chasing? Have you ordered the correct bearings?
Our K20 Complete High Compression Built Bottom End is a professional-grade short block that brings world-class engineering to your home garage.
This is the exact meticulous blueprinting and attention to detail that we put into our flagship highest-spec K20R engines.
Let’s break it down:
✅ Prepared by our engine builders with 20+ years of expertise. We handle the machining, balancing, and de-burring so you don’t have to.
✅ Every Genuine Honda bearing is individually measured and matched for exact oil film clearances.
✅ Precise piston-to-wall clearances optimised for high-performance reliability.
✅ We’ve paired Genuine Honda reliability with Wössner High-Compression Forged Pistons & Rods (featuring ARP 2000 bolts).
Think of this as the heavy lifting handled by the pros, ready for your choice of cylinder head and leaving you to finish the build with total confidence.
We are also offering this on a customer supplied crank / block option. Built to order, 3-5 day lead time.
