Cams:

Upgrade the performance of your K20 K24 with a set of Bourne HPP Performance Honda drop in cams. These cams are perfect for championships that use power to weight classes such as 750MC Hot Hatch and Club Enduro. This set of drop in's are ideal for up to 260 horsepower on a stock engine.

 

Our Honda K20 K24 Drop In cams were put to the test at Tegiwa HQ to see how they perform compared to other brands on the market.

"Although we can’t replicate the test on the car we’ve tested the others on. We have however, tested them on a K20A2 powered EP3. The EP3 had basic bolt-on modifications including a Tegiwa carbon airboxTegiwa exhaust manifold and RRC intake manifold."

"Considering this car only has a RRC manifold, not a Skunk2 Ultra Street Intake Manifold like the EK that we did the tests on We saw peak figures of 249.9bhp and 164.7 lbf. ft, the same horsepower as the Skunk2 drop-ins and 4.6 lbf. ft more than the JDM K20A cams! We can speculate that the car could potentially make an extra 5 horsepower too when we look at our intake manifold test and compare the difference between the Skunk2 Ultra Street and the RRC."
