Against The Grain
What up HT!? Is there any way to fit an S2000 intake manifold on a K20a motor swap? The reason being, I'd like to just run an intake from the passenger side front bumper straight up to the throttle body since it would be facing the passenger side. Is this possible?

Kenny, anything is possible my friend. You could weld the plenum on the K runners, but better yet, use an RBC K20 intake manifold and re-weld the throttle body on the other side of the plenum. The RBC mani's have the best flow for your setup and will yield the best power. In my personal opinion, just use the RBC and run the intake on the driver's side of the car like stock. This swap has been done countless times now, and nobody seems to have any major issues with the throttle body being on that side.

Love the magazine and I love Hondas. I have a '93 Integra with the candy red paint that you'll find on your website's Rides section. I have a Skunk2 68mm Throttle Body and Pro Series Intake Manifold that I'm trying to install but noticed that there are a lot of extra parts and vacuum hoses that the Skunk2 throttle Body doesn't use. I'm guessing that the one for the water lines gets bypassed, but what about the lines that go to the EVAP canister and back up? Do I cap those off or remove them completely? Also, I heard that the fuel rail needs to be replaced with a '94-'01 version, but can't I install mine backwards or modify it? What's a better fuel rail for around $100? Thanks for your time.

You're right about bypassing the water lines. Skunk2 Pro Series throttle bodies eliminate the Fast Idle Valve, which you'd normally find underneath the OEM throttle body. The Fast Idle Valve heats up the intake charge, so getting rid of it is a good thing. However, you'll need to either splice the two hoses together, or replace both with a longer one. Pro Series throttle bodies also won't include vacuum provisions for the EVAP canister. Remove the vacuum lines from your canister and cap off the ports because you won't be using it any longer. Of course, this configuration is not street-legal since the Pro Series throttle body is designed for race-use only, but never mind all of that. Fortunately, you can connect your purge solenoid's vacuum line to the rear side of the Pro Series intake manifold. As far as the fuel rail goes, you're right; yours won't work, so why not cough up another hundred bucks, and just complete the package with a Skunk2 Composite fuel rail? Skunk2 rails are lighter and stronger than your stock one, fit like you'd expect, and will keep your fuel cooler for more power. Do it!
