GRP Engine, Buggy .21

GRP performance at a non-tuned price!

At a Glance

The GRP .21 Buggy Engine is designed in Italy by GRP, under the direct technical supervision of Mario Rossi. This 1/8-scale non-tuned racing engine is produced with high-quality materials and undergoes a thorough manufacturing process. The engine's Temperature Control System (TCS) keeps the heat from the block from transferring to the carburetor causing intake changes and running out of tune.
All of the components used in the non-tuned engines are interchangeable with GRP’s tuned engine parts. This allows the non-tuned engines to be customized for increased performance, while eliminating the need to purchase a new engine. Each engine comes in a GRP plastic box, complete with decals.
