SPS engine configurator for naturally aspirated engines

With the SPS motor configurator you can put together your motor the way you want it! In addition, for the first time it is possible to order fully built cylinder blocks and cylinder heads from us, ready to install for your engine at home! Of course, as usual, we also offer our complete engines as parts packages for people who would like to build their engine themselves at home using our components.

Here in the area for building naturally aspirated engines you can put together your dream engine for use in combination with the OEM intake or ITB system. Here you can choose between 3 different basic concepts, which are the ones our customers request most frequently:

Budget: The inexpensive way to build your engine. When creating the engines, the focus was on your wallet. Nevertheless, the packages are made of extremely high-quality components in order to meet our high quality standards. Can easily be used with OEM intake system

Performance: Optimal for the successful middle ground between track tool on the weekend and occasional trips during the week. Perfectly suited for those who don't want to build a pure track tool, but still want a high increase in performance. An ITB system is recommended here

Race: The ultimate engine for ITB racing vehicles. Accordingly, the packages are designed for maximum performance and durability. Not recommended for daily or road vehicles, but intended exclusively for pure racing use

About the dropdowns:

Engine:

Here you can choose between all different basic engines. Here you simply select the engine that is installed or is to be installed in your car.

Cylinder head:

Here you can choose between the basic concepts as stated above. In the budget version, the cylinder head is revised, resealed and fitted with new intake valves and our Stage 1 camshafts. The inlet valves are always recommended, as they tend to hammer into the head and then no longer seal properly. In addition, a reroute kit is used to counteract the thermal stress. This way you´ll always keep a “cool head”.
In the performance version, our Stage 2 camshafts are used with harder valve springs in order to be able to generate more power. You also get adjustable camshaft gears so that you can properly adjust the new camshafts.
The Race variant then increases the performance again via our Stage 3 camshafts including hardened valve springs and mechanical cam followers and cylinder head machining. This means you are perfectly prepared for pure use on the racetrack. This conversion is not recommended for use in everyday road use, as it can result in rough idling.
You also have the option of cutting off the cylinder head completely of your list if you simply need a new cylinder block and want to continue using your original cylinder head.

Cylinder block:

Here you can also choose between our three basic concepts. In the budget version, the engine is completely resealed. In addition, the engine is equipped with new ACL Race Series bearings. Of course, the right water pump for your engine as well as all the necessary seals are included in the scope of delivery.
The performance cylinder block prepares you perfectly for the use of an individual throttle system. By using Wössner forged pistons and the use of Boundary oil pump (only NA to NBFL), your engine can withstand higher rpm´s in a much more stable manner.
In the race configuration, H-shaft connecting rods and a boundary oil pump are used to ensure stability at very high power and rpm´s. This means you are prepared for absolutely anything and beyond.
Here you can also deselect the cylinder block completely to only get a cylinder head or the components to assemble the head.

Assembly:

Last but not least, you can choose between the parts package or the configuration that we assemble in house for you. If you choose "without assembly" you will receive the respective parts to assemble yourself, if you choose "with assembly" you will have your fully assembled cylinder head, cylinder block or even the entire engine delivered to your home. In the variant with assembly, the basic components (cylinder block, cylinder head or the complete engine) must be seen in exchange for the original components from you. Accordingly, you must then send us the respective components.
