Few questions from an altima owner looking towards a 240

[lifeofshadoze]

S14 to be precise. Like the altima, and my faith in the ka engine, ill be going all motor, so heres a few of my questions:

I have the hotshot CAI on my current altima, the gain i have in low end torque doesnt warrant the loss i take up top.is this true in the 240 sense as well?

Second, how difficult would u consider the installation of a header on the vertically positioned engine? Looks difficult imo.

Thanks, appreciate any comments.

the intake is worth it, as it doesn't lose power on the top end until nearly 7500. As for the headers... 8 bolts and a gasket will have you doing good.

i thought redline was 6500? Is the 7500 being considered with a complete rebuild that could utilize a higher revving to obtain power?
