and for the last fucking time, do the work and the fucking k20 swap is not 6k. yes, a k20a2 will run you that, but not a k20a3, which is still an improvement over the d series. and i know people running 500hp+ on d series, but you know what, they have TURBO manifolds and turbo exhausts. they didnt get there by slapping a turbo on, upping the boost, and ghetto fabbing some bullshit exhaust and manifold system. not to mention your d17 will hold maybe 17psi before some mods are needed to keep from blowing down the road. could you run more? yea, is it smart? prolly not.
