Lack of oxygen... Sensor
Q I have an EG Si with a LS/VTEC turbo swap and the car didn't come with an 02 sensor. Which one do I use? An EX/Si or a B-series 02 sensor? And are all B-series 02 sensors the same?

A Pretty much all Honda 02 sensors are interchangeable from OBD1 on sharing the same thread size, pitch and pigtail connections. The main difference from model-to-model would be the length of wire, as long as the length is adequate to reach the other end of the connector on your harness, you should be good to go. Assuming you're still on an OBD1 system you only need one 02, but anything past 1996 will have a Primary 02 (before the cat) and Secondary 02 (after the cat) to comply with OBD2 standards.

Du Hasst Mich Intakestein
Q I am currently assigned to Ramstein AB Germany, which is a blessing in two ways. First the beer is legendary, but secondly and most importantly, I have the opportunity to own my dream car - a R32 Nissan Skyline GT-R. Now this car is already a pleasure to drive, it's Mine's tuned, need I say more? I am planning on doing some work to it, starting by replacing the stock 02 sensor and getting rid of those pesky and restrictive MAFs and replacing them with a MAP sensor. Now to my question, I really want to replace my stock intake. I have found a few including the A'PEXi Super Suction kit, which I think would be best. I just wanted to see if you had any suggestions?

A Holy Shit, Ramstein Is One Of Our Favorite Bands!
That's awesome that you live with them, what's that like? Probably super epic, we can only imagine the drunken shenanigans you must get into! Anyway on to your suction dilemma. Any properly manufactured aftermarket intake will probably do wonders for the car and contrary to the name, the A'PEXi unit doesn't suck, it rocks. That would be a safe bet in our book.

Hey What's Up, I'm Pretty Into Cars
Q The name's Jake; they call me Jack, from New Castle, PA and I'm 17 and just starting to get pretty into cars and absolutely love Hondas. I'm about to get a Civic coupe with any luck. But on that note, I was wondering what exactly is a 'after-cat' exhaust system? I would love to fix this car up and make it a nice tuner but I have a lot to learn yet.

A Jake err Jack... or JTZ - whatever the hell your name is, the 'after-cat' is really a mythical tuning piece, much like a MoTeC-system exhaust. Everyone has heard about it from one time to another but nobody has ever seen one in its native environment. Actually we're just pulling your chain, Jake Jack. After-cat is a phrase describing an exhaust system that runs from the catalytic converter out to the back of the exhaust system, hence the name. Other examples would be axle-back (rear section only) or turbo-back (down-pipe, cat delete and exhaust) or header-back (cat delete and exhaust).

Picture Me Slide'n'!
Q First off I'd like to say that you guys put out a killer mag every month! I really love the Datsun 240Z style. But I also love drifting and I was wondering if the 240Z platform would be any good? I understand that with enough skill anything is driftable, but being a noob like me I was wondering if it would be a good starting platform and one that could accommodate my improvements, as I get better at drifting? Keep up the good work.
