Boost the power of your Subaru with an IAG Performance short block engine from Modern Automotive Performance.

One of the great things about Subaru’s sports models such as the BRZ coupe and the Impreza WRX is the engine — it starts out with pretty great specs and power. At Modern Automotive Performance, however, we are always looking for ways to improve and increase output through modifications. A short block modification goes a long way toward upgrading your Subaru for higher stages of competitive racing.

Our mechanics have decades of collective experience making engine modifications and have learned more than a thing or two about quality manufacturers. IAG Performance knows Subarus like the back of their hands as they’ve grown into an impressive manufacturing plant forging some of the highest-quality short blocks in the business.

Precision crafted short blocks have been designed to address and eliminate issues found in Subaru engines. Its closed deck process results in amazingly strong casting for durable cylinders. Superior materials ensure top performance and long life, and innovative design helps address virtually every weakness, preparing you for top performance.
