At RR2 MOTORSPORT, we have created this engine kit as the best option in terms of quality and value for money. This is based on our extensive experience in the field, carefully evaluating the most suitable products for the conditions and requirements of the engine they are intended for.

Why Choose RR2 MOTORSPORT?

-Decades of experience in competition engine preparation

-Careful selection of premium components

-Focus on maximum power and reliability

Only the highest quality brands – no compromises

There are cheaper kits on the market, but they lack the durability and performance standards we require at RR2 MOTORSPORT.

Remember, extreme power requires extreme attention to detail..

IMPORTANT NOTE:
The preparation of a competition engine must be carried out by a qualified professional in this field. Any mechanic can assemble an engine, but it is a completely different matter to perform the necessary calculations regarding tolerances, correct camshaft overlap, balancing, head chamber volume, selecting the ideal head gasket thickness, calculating compression ratio, modifying cylinder head flow, etc. All of this requires specific tools and expertise to guarantee maximum power and reliability of the engine. The higher the power output, the greater the need for extreme attention to every detail in the preparation. Remember: an engine subjected to extreme workloads requires the highest quality components. While there are other manufacturers offering cheaper alternatives, at RR2 MOTORSPORT we have disregarded them as they do not meet the level of quality we consider essential.

HIGH QUALITY AND VERY COMPETITIVE PRICE

For Stage 2 and Stage 3, we recommend the use of exclusive competition oils, specifically formulated for this type of engine:
DRIVEN XP9, XP6 or HR3, developed to withstand the maximum demands of the engine.

Additional recommendations to achieve the estimated power output:
Stage 1 (≈170 HP): 4-1 exhaust manifold, performance air filter, complete exhaust system.
Stage 2 (≈200 HP): 4-1 exhaust manifold, ECU remapping/programming.
Stage 3 (≈250 HP): 4-1 exhaust manifold, programmable ECU, independent throttle bodies.

​These are some of the essential recommendations to reach the approximate power figures for each stage. However, final results may vary depending on the expertise and specific work carried out by the engine builder.
