What a journey it's been over the last few weeks to get car and my road car to 2026. I hatched a plan with Caleb when the entries opened this year's event, and we read the rules for the new NA class; we decided to have a red-hot crack at getting the two cars up to spec to try and get on the podium. With out of the country, our trump card was gone, and it was up to us to take on the Sydney-siders. The secret weapon I had been working on for well over 12 months now with our cylinder head guru Gerry was the new FA24 CNC ported cylinder heads, added to this were a couple of sets of custom FA24 billet camshafts that Tighe Cams made for me before they closed in Dec 2025. The first set of finished heads arrived with three weeks to go, so we got straight into removing my engine and fitting the new heads and cams; we lost four days waiting for valve shims to come from Melbourne over the AFL Grand Final weekend. Got the engine in and found we had a problem with one of the cams, so out it came again, pulled it apart, and refitted, lost another three days. Got the car back together and on the dyno on Wednesday the 30th. We had a test day at QR booked for the 7th, and we hadn't even started pulling Caleb's apart yet! While I tuned mine on Thursday, Trent pulled Caleb's engine out. I picked Caleb's heads up from Gerry on Friday and started putting the engine together on Saturday while Caleb made me a front splitter for my car. Sunday NRL Grand Final day, I spent getting Caleb's engine finished so Trent could fit it on the Monday public holiday while I finished prepping my car. Tuesday, I tuned Caleb's car, and we made it to the test day at QR on the Wednesday as planned. The test day showed that my car was running hot, so we had Thursday to move the engine oil cooler and add bonnet vents and pack up ready to leave at 5:30 am the next morning. We made it to Sydney, the cars ran faultlessly, Caleb won NA class, and I came third with Mitchell Brooks from Prospeed Racing in a Gen 2 BRZ in second place. The new head and cam package made almost 20% more power on both cars, and they only had limited tuning time, so there's much more left in them yet, but we all need a weekend off to recover as it's been a hectic few weeks.
Huge thanks to my team for putting the hours to get it done.

This is something that i am truly excited about, the dream of having a 200+ RWKW NA FA24 is getting closer.
Gerry from Advanced Engine Performance has performed his magic on hand porting and modifying a set of FA24 heads so that they can then be digitised and a CNC program done. Soon we will have the first set of CNC race heads to suit the FA24 and I have a the first set of custom cams here ready to go with them.
The cylinder heads feature 1mm oversize custom exhaust valves, extensive inlet and exhaust porting all done with flow bench testing. The combustion chambers are also modified to help reduce knock and increase power.
The end goal is to able to offer a head and cam package for both NA race and FI applications. The first set will go on my FA24 swapped 2017 car for extensive dyno testing and then run at Subinats in October.
Full specs, flow numbers and pricing for these cylinder heads will be available in the coming months.

It's been a busy couple of weeks and one job that have had in is this built engine for this lucky customer.
This our street / mild track package with upgraded head studs.
This package consists of
* Block honed to size
* ACL race series main and conrod bearings
* New OEM pistons and rings gapped for FI.
* Supertech H beam forged conrods.
* Pistons and rods are balanced in house.
* All bearing clearances check before assembly.
* ARP CA 625+ head studs ( optional ) normally ARP 2000 head studs.
* Cometic or HKS head gaskets ( depends on availability )
* Reconditioned cylinder heads with new valve stem seals and GSC Beehive valve springs.
* New timing chains and guides
* Camshaft variators are dismantled and cleaned
* Camshafts are checked for straightness and journals micro polished.
* Valve clearances are all set to our spec.
* OEM gaskets and o-rings used throughout.
* HKS Spark plugs
* This engine was also optioned with a Killer Bee oil pick up.
One place that we do differ to many is that we use 5W-30 Joe Gibbs Driven run in oil as all other run in oils are a higher weight than what we like to use on a new engine with tight clearances.
This combination is capable of running 16 - 18psi reliably for mild track use and even more for street use. These are also a great combo for people who want a daily driver that will do bulk klms without the worry of forge pistons wearing and rattling over time.

Now for a few thousand km of running in and then back on the dyno to max the current G25-550.
Pricing for these starts at $12,500 depending on options.

Getting ready for the first test day of the year, I have just had a new turbo manifold made, thanks to Scott.
We have been have issues with cracking the manifold ever since we swithced to the larger frame G30-770 so i bit the bullet and completely changed the mounting system and then had a new stainless steam pipe manifold made.
This is still the FA20 as we haven't finished with it yet and the FA24 isn't going to be ready until mid year for Austimeattack.

Upgrades for this year include changing shocks.
I am 100% a fan of the MCA reds that have served me well for many years and we fit them to all of our racecar builds but I had these come up at the right price and they give me 3 way adjustment over just single with the old ones.
More changes are coming soon so watch this space.
