If you like to make your RC vehicle as realistic looking as possible, here is something that you can add to your trail truck which you may not have considered. The 1/10-scale RC4WD V8 Scale Engine along with engine accessories. Typically, people will only focus on the outside of the truck body when adding scale details. This V8 Scale Engine with accessories adds another level of detail, but this time under the body. It is additions like these that can turn a nice-looking scale trail truck into an outstanding-looking trail truck.

We recently pulled our customized RC4WD Chevy Blazer, Trail Finder 2 project truck off the shelf to do some more scale work on it. (That is the beauty of these scale rigs, there always seems to be more scale detail that you can add to them and that is a big part of what makes this hobby so much fun…the tinkering.) In this article we will show you the RC4WD 1/10 V8 Scale Engine that we started with and the accessories that we installed onto it to make the engine look even more real. Now we did not use all the engine accessories that are available from RC4WD, so click the following link if you want to see all the items they offer.
RC4WD 1/10 V8 Scale Engine—part number: Z-S1043
The RC4WD 1/10 V8 Scale Engine is a really cool product. It not only adds scale realism to a trail truck, it is also designed to hide the RC motor inside of it. The Engine is beautifully CNC machined from billet aluminum and held together with tiny hardware. The crankcase is anodized a burnt-orange color, the oil pan is anodized black and the rest is anodized silver. Mounted on top is a nicely detailed manifold with air-cleaner that are bordered by realistic looking valve covers. Depending on how handy you are, you could install the V8 Scale Engine in most trail trucks. We installed our engine in the RC4WD Trail Finder 2 chassis without any issues. Spacing tends to get a little tight when you add the optional pulleys and radiator, so you may have to be a bit creative to get everything installed. Included with the V8 Engine is a miniature scale hex bolt tool for assembly and disassembly.
Thermostat Housing for V8 Motor—part number: Z-S1739
The first of the RC4WD V8 Scale Engine accessories that we added is this Thermostat Housing. It is quite small and includes the mounting hardware and the tiny scale hex bolt tool to install it onto the manifold. RC4WD CNC machined the Thermostat Housing out of billet aluminum and then anodized silver. The idea with this part is that it works in conjunction with the radiator. A cooling hose from the radiator is attached to the Thermostat Housing. Attaching it to the engine is very quick and easy.
RC4WD Pulley Kit w/Belt for V8 Scale Engine—part number: Z-S1537
If your funds are limited and you can only start off by adding one accessory to the V8 Scale Engine, then get the RC4WD Pulley Kit w/Belt. It adds a lot of scale detail to the engine to make it look more real. This Pulley Kit includes a timing cover, water pump spacer, pulleys, bushings belts and mounting hardware. All the parts are very nicely machined from aluminum except for the two silicone rubber imitation belts (one is a spare).
For installation, you will need to remove the stock timing cover from the engine because the Pulley Kit comes with a new front cover that has a threaded boss on it so that you can attach the lower pulley. There are a lot of tiny screws that secure the cover onto the engine. For added insurance, we used some thread lock to keep the screws from vibrating loose.
If you plan to use the RC4WD Water Pump shown below, you will need to install it now before the rest of the Pulley Kit. The water pump spacer that comes with this kit will not be used if you use the RC4WD Water Pump. When you install the lower pulley, the flange goes on the outside of the pulley so that it properly lines up with the belt. And for each of the pulleys, RC4WD includes small metal bushings that allow the pulleys to spin…pretty neat.
RC4WD Water Pump for V8 Scale Engine—part number: Z-S1719
If you are planning to install the RC4WD Radiator and Hose, you will definitely want to pick up this RC4WD Water Pump as well. It comes with the neck so that you can fit the hose that goes down and attaches to the radiator. The Water Pump is nicely CNC machined from billet aluminum and anodized silver. RC4WD includes the mounting hardware to make install a breeze.
When you are installing the Water Pump and you plan to also add the RC4WD Pulley Kit w/Belt, you will need to mount the Water Pump at the same time you put on the Pulley Kit. The reason being is that the Pulley Kit comes with a different front cover than what the RC4WD 1/10 V8 Scale Engine comes with. So, first you install the new front cover that comes with the Pulley Kit and then you install the Water Pump.
Distributor and Rubber Tube for V8 Motor—part number: Z-S1738
One thing that helps to make a scale engine look more the part is adding wiring and that is where the Distributor and Rubber Tube for V8 Motor come in. The distributor is incredibly well machined from aluminum to look just like one off of a real V8 engine. It is black anodized and fitted with threaded holes to attach tiny set screws which are used to secure the included tubing. The tubing replicates spark plug wires.
The first step to mount the Distributor and Rubber Tube onto the V8 Engine is to install the tiny set screws into the distributor cap and into the engine block. Now you attach the tubing to the set screws in the distributor cap and then cut the tubing to length. If you are incorporating the RC4WD Plastic Exhaust Headers onto the Engine, don’t attach the other end of the tubing on the set screws/‘spark plugs’ in the engine block. It is much easier to thread the tubing through the Exhaust Headers first before the headers are installed and then you can plug the tubing onto the ‘spark plugs’. Once that is completed, you can install the Exhaust Headers onto the engine block.
Plastic Exhaust Headers for V8 Motor—part number: Z-S1775
These RC4WD Plastic Exhaust Headers are the only non-alloy item that we are adding to the V8 Scale Engine. What makes these Headers special is that they are not molded plastic, but rather 3D printed with a white colored filament. I know what you are thinking. “The quality will not be very good because it is 3D printed.” But on the contrary, these Exhaust Headers have a very good finish and don’t even look like they were 3D printed. Once you get them in your hands, you can see the quality of these parts and scale realism built into them. They are so realistic that they are even hollow like the real deal.
Installing the Plastic Exhaust Headers is straightforward, especially if you are not also adding the RC4WD Distributor and Rubber Tube (see the Distributor and Rubber Tube section above). Just bolt them onto the engine block with the included hardware using the hex bolt tool that also comes in the package. You have the option of painting the Headers. For this project, we decided to leave them white to mimic thermal header wrap. Once you have the Headers mounted and the Engine installed into the chassis, the headers will be visible if you peek through the wheel well. That is if you are not using fender wells.
RC4WD Radiator and Hose for V8 Motor—part number: Z-S1773
The last item we added to our RC4WD V8 Scale Engine was the RC4WD Radiator and Hose. We were blown away when we opened first opened the package. This Radiator is simply incredible looking. It is entirely made of CNC machined billet aluminum and is designed with such detail that you can actually see through the radiator. Plus it comes equipped with a radiator cap that unscrews, inlet and outlet posts so that you can connect the cooling hoses to the engine and a RC4WD logo machined onto the top. Along with the Radiator itself, RC4WD includes tubing to act as the cooling hoses and clamps to keep the tubing securely attached to the radiator and engine.
Installation of the RC4WD Radiator and Hose will depend on the vehicle you are adding it to. The bottom of the Radiator has threaded screw holes on the bottom so that you can mount it onto the chassis. You may need to add a mount so that you can securely attach the Radiator. On our truck, we had to move the steering servo forward in order for there to be enough room for the pulleys and the radiator.
