Once the B18 was in and running, there was still some work to do to pass the BAR inspection. For the air intake tube, I borrowed an air box that covers up the top of the intake filter just in case the inspector makes a big deal about it being exposed. At the inspection, they did both a visual test and emissions test. The only thing they looked for in the visual test was that there was a catalytic converter and two oxygen sensors. They didn't touch anything or move anything around. In fact, my power steering pump was removed and the lines were looped into the reservoir, but they didn't point that out.
For the emissions test, I used the cat that was supplied with my swap. When the results came in, I was high in emissions across the board. I contemplated taking it to a shop to have them check it out, but decided to get a new cat and oxygen sensors instead since they looked incredibly rusty. I got the O2 sensors from Kragen, one universal and one OEM by Bosch. I got a CARB legal Carsound cat through a local muffler shop and had them weld it on to my stock Civic exhaust. Overall, parts and labor for all the emissions equipment was $600. When I went back to the BAR inspection, I had passed below average in all three categories except for HCO. I believe this was caused by using 87 octane instead of 91, which burns more completely in this engine. So I would recommend using 91 before a smog inspection despite what people say in the forums.
And finally, for daily driving I needed air conditioning and power steering. You will need an A/C belt for a GSR (P72). Power steering is a little trickier. You'll need a P/S pump from a 99-00 Civic SI because the hose on my Civic would not fit an Integra steering pump. This applies to 6th Gen Civics, but I'm not sure about other generations. With the SI pump, it fit like a charm with no cutting at all. The mounting brackets, however, can be from a GSR(P72). I'm not sure if the SI brackets will fit, but I'm sure it does.
Conclusion
Overall it was a successful swap. I was a bit disappointed with the emissions deal, but it's all fixed now. Power wise, there is a huge difference especially in freeway driving. Merging into oncoming traffic is much easier and VTEC sounds very aggressive when it engages. To help pinpoint where exactly it engages, I recommend getting a tachometer and even a VTEC light. I've installed both and they work great.
However, the reality is still apparent when compared to other cars on the road today. A B18C1 powered Civic will still have some trouble trying to outrun V6 cars with 250+ horsepower, especially going uphill. This swap will not turn a grocery getter into a Corvette. I see it as turning a super slow car into something more decent but not overly powerful. While a B18C1 swap increases horsepower by a lot, only weight reduction and tuning (along with internal modifications) will make it competitive on the road.
But still, I cannot prove this point until I actually see it's potential on the 1/4 mile track. If it makes mid 15s, then I'll be competing with the RSX, Scion tC, etc. I'd also have to replace my stock exhaust with a more free flowing one, and take into account all the sound dampening in the car. Overall, it still makes an excellent daily driver in it's "stock" form!
