How strong is the k20a valve train compared to the k20a2?


Can the k20a withstand K pro and stage 2 cams fully tuned or will it require new springs and valves? By require I mean will it be safe without the addition of new spings and valves.


I am planning on buying a k20a swap and selling my k20a2. So that's why I am asking all these questions. I will have the cams put in before the motor is installed in the car also. I plan on getting the toda cams.

 

If you get the N2 cams then I would reccomend getting the toda valvesprings. they are different from the K20As. Todas are dual valve spring instead of single. Plus they are designed for those camshafts
