We recently built one of our Stage One RB26 engines for an R33 GT-R so we thought we would document it so everyone could see what goes into one of our built engines.

Chemical cleaned engine block, on the stand she goes.

Machine hone and finish hone.

Crankshaft polished, balanced and grub screwed.

Factory con rods with ARP bolts, Nitto pistons and ACL race series bearings.

Bottom end assembled with the parts above, new core plugs and fresh lick of paint.

Full cylinder head service.

ARP head studs fitted, Nitto head gasket and cylinder head fitted.

That’s the basic idea of what goes on behind one of our stage one engines.
They also include billet oil pump gears, Tomei sump baffles and our own internal oil control mods.
From here all the bolt ons are fitted along with new gaskets, seals, timing belt kit and water pump.
Then the engine is fitted to the car, run in on the dyno, fully tuned and delivered to the customer ready to drive.
This kind of engine will support up to 600hp at the wheels.

We finally got cracking on getting the exterior mods on our R32 GT-R done.

It begins with an N1 front bumper with a carbon fibre Abflug splitter.
Next were a pair of N1 side skirts and we made up some custom carbon fibre skirt extensions.

The carbon extensions even out the height of the sides with the front perfectly.

Finally a set of D-Speed clear indicators replace the standard amber ones giving the car a much fresher look.

We also gave the old girl some updated badges with an R35 GT-R boot badge and R34 GT-R front guard badges.

Stay tuned as the engine mods are about to begin, we will be chasing a 10 second time slip while retaining the stock bottom end with this car.

Here are some photos of an S13 Silvia with an RB25 conversion we recently finished working on.
We did the conversion wiring as well as a full wire tuck and the stainless steel intercooler piping.

We recently picked up this neat R32 GTR which we will be building to test some of our new parts we are developing.
So far mods have been a set of coil overs and 18×10.5″ BBS LM wheels.
Stay tuned for many more mods in the near future.

Here are some quick pics of Troy’s FUUARK S14 we just finished.

The car got a full wire tuck and detailed engine bay.
Aeroflow plumbing, Aeroflow power steering and coolant reservoirs
Custom catch can, Mazworx plenum and fuel rail kit with 1000cc injectors.
Haltech Platinum Pro plug in ECU, Haltech boost control solenoid, 3 BAR map sensor and AEM wideband sensor and controller.
The car runs an S15 engine, loom and ECU so we had to graft the S15 engine loom with the original S14 body loom.

The car managed 274kw on 18psi running on E85 fuel.

Here are some progress photos of one of the RB26 engines we have in the build at the shop.
This particular engine is retaining the 2.6 litre capacity using Nitto Pistons and H beam rods, and a new factory crankshaft.

Piston crowns are coated in a heat proof gold coating to minimise heat soak into the pistons which keeps more heat in the combustion process increasing engine efficiency.
Piston skirts are coated in a Teflon coating that minimises friction between the bore and the piston, which again makes the engine more efficient.

Combustion chambers and valves have been coated in a grey heat proof coating to minimise heat soak into the cylinder head and valves which also keeps the heat in the combustion process instead of in the engine components.
The cylinder head was fitted with 1mm bigger valves and has received a very nice port job.

ARP head studs fitted to the block and then the head goes on.

We’ll be posting more pics in the coming weeks as the rest of the parts start to arrive from Japan.
