Hey everyone I been thinking of going with the k2h on my eg f20b swap instead of the s2 manifold.I have research a lot on this already s2 vs euro I kind of like the midrange the roskos euro offers but since I have pro 2 cams I think it will fall short on the topend past 8000s rpms.Now I seen the difference in powerbands and peak numbers on some of the k20 manifolds the rbc look nice with good topend but the k20a fd2 manifold made much higher whp and wqt numbers.Why the k20 manifold?the way I see it the k20 is very similar to the f20b both 85mm bore both 2.0s both are made from the factory to rev very high thats why I think a k2h setup will be better for the f20b.Any one have a dyno chart of a k2h or any feedback on it???Let me throw this in here to Im debating on getting the vibrant header that has the 2.5 collector not sure yet my goal is in the 220whp maybe more I already have walbro pump,s300 on a street tune,440cc s,2.5 no cat with cheap obx back fires sometime I'm thinking vibrant muffler,68 s2 TB,password jdm carbon intake,supertech dual springs and I'm saving to go f2b with prolly a b16 trans I sure I have more modds to.
