What is Bpu?
1.
BPU is a term commonly used in the "tuner culture." This term stands for Basic Performance Upgrades.
Another use of the term BPU sometimes occurs when describing a vehicle - such as saying, "He's got a BPU Supra." When used in this fashion, the BPU is being an adjective and describes the car as having its (the car's) performance upgraded with basic parts.
BPU's mainly include exhaust systems, headers, downpipes, smaller-sized turbos, etc. (Upgrades that are not considered basic include twin-turbo systems that are not stock, boring out the engine, engine-swaps, nitrous, etc.)
Vehicles that are commonly referred to as being "BPU" are Civics (well..most Hondas), Supras, Evos, STIs, etc. This is one term in the "tuning culture" that is not limited to Japanese automobiles.
