There are three things you can do. First, consider converting the car to OBD-1. You'll need a jumper harness and an OBD-1 ECU to do this. The OBD-1 ECU will recognize only one oxygen sensor, and can be chipped and tuned to maximize your engine's output. This is the best method, especially if you plan on modifying the engine in the future. Your second option is to install an oxygen sensor simulator. Such simulators use a series of resistors that fool the ECU into thinking that the temperatures are hotter that what they are, but are often unpredictable and not considered a foolproof solution. Lastly, you can put your catalytic converter back on. The amount of power you've added by removing it may likely not even be worth the trouble.
Accords And K Swaps
I'm looking for information regarding engine swaps for my 10th Anniversary Edition, '93 Accord. I'd like to do either a K24 or K20 swap but can't seem to find reliable technical information anywhere. I wrote to you guys a while back and found you very helpful. If you could please let me know what parts I'll need for such a swap as well as any fabrication or modifications that I'll need to make, that would be great. I've got a year to get everything together and then I'm starting. I don't want this to look like some chop shop welded an engine into my car-I want this to be done professionally. Any information would be greatly appreciated.

There is no need for hacking when you use Hasport's kit. The swap kit is designed for the 2.4-liter K-series engines as well as the K20A Euro R engines, which all feature a different rear-mount design when compared to other K-series powerplants. Hasport designed the kit this way so that guys like you could take advantage of the higher-displacement, yet more reasonably priced K engines. You'll also need to source a Type R or Type S intermediate shaft to match up with Hasport's custom axles and a CRV right-side bracket. The rest of the swap is as you'd expect: customize some fuel lines, get creative with the radiator hoses and radiator, figure out how to get the exhaust system to line up, and call Rywire for one of its PNP conversion harnesses.
K-Series Lsds
What's up, Honda Tuning? I have an '05 EP3 Civic with a K24A4 engine swap. It's cool, but I was curious about the transmission. Of course, I'm running the stock A3's five-speed right now. Is there a way to get an LSD with this combo, or is there another tranny that I can use that has one already? I love the magazine; keep up the good work.

Your best bet is to use an aftermarket LSD and upgrade to a transmission from the '05-'06 RSX. The Japanese market's Type R transmission is also an option; it's a six-speed, has a 4.7:1 final drive gear, and an OEM LSD. But the biggest issue here is that you have an '05 EP3, so the speed signal won't work with your gauge cluster. Don't worry though, there are companies out there that can convert the two signals to work together. Both the '05-'06 RSX transmission and the '02-'04 Type R have the same final drive and gear ratios, so neither is any better in that respect.
