D15B - SOHC 1.5L
The 1.5L DX engine is by no means a performance engine. This engine was made for good gas mileage and reliability which it excels at. There is aftermarket parts available for this engine but do not expect significant gains. Changing the fuel injection to a Si injection will increase horsepower and this would probably be the best mod for this engine since the Dual point injection does not respond well to mods.

D16A - SOHC 1.6L
The 1.6L SOHC Si engine came stock in the 88-91 Civic Si's. This engine offers a nice peppy feeling and good gas economy. Most Civics with the 1.6L SOHC run the 1/4 mile in the 16's. Not blistering fast but still offers more power then the DX or base. This engine does have a wide array of aftermarket support so finding bolt on mods should not be a problem.
D16Z6 - SOHC 1.6L VTEC
The 1.6L SOHC VTEC is a nice little engine that almost matches performance of the ZC. From what I have seen most Civic 4th Gens will run 15's in 1/4 Mile with this engine. This engine also is a direct bolt on. Only issue you will have with this engine is the wiring of the VTEC. Many people prefer this engine over the ZC for 2 reasons. More performance parts are available for the SOHC VTEC and also emmisions tests the SOHC VTEC will pass with flying colors while the ZC might be a little tricky
D16Y8 - SOHC 1.6L VTEC
The D16Y8 is very similar to the D16Z6 except for it was produced in the 96-00 Civic EX. It has slightly different specs as well. When installing into a 4th Gen Civic a p28 ECU (92-95 Si/EX) is used. Please refer to D16Z6 instructions for installation."
ZC - DOHC 1.6L
The ZC engine came stock in the Si's in Japan. With 135hp on tap a 4th gen will scoot the 1/4 mile in the 15's with basic mods. This engine is a direct bolt on. You will want to change the ECU to a Integra ECU and the best bet is to have a SI trans. I personally have a ZC in my Civic HB and I'm very happy with it. The ZC has a bad rap as being an engine that breaks down but I don't think that is the case at all, with all used engines you take risks. I think the ZC has plenty of power, you may not be able to beat a B16a 4th Gen but you can give most imports a run for the money with this engine.

The Euro version of the "ZC"
B16a - DOHC 1.6L VTEC
The B16a is a great engine for the 88-91 Civics. In Japan the SIR's came stock with this engine. Imagine 160hp from the factory!? Well the B16a sounds nice but it is NOT a direct bolt on to the 88-91 Civics. You will need engine mounts, wiring harness and other little parts that will give you a major headache. I recommend this swap to anyone that has extensive knowledge about Honda engines, or better yet have a professional swap it in. It wont be cheap but you will be happy with the results. from what I hear most people who swap these in with basic mods run the 1/4 mile in mid 14's, not to shabby eh?
LS-R/LS-VTEC/"FRANKENSTEIN" - DOHC 1.8L VTEC
One word.......Monster. That's the only way to describe this engine. As you may already have noticed this isn't a stock Honda motor. It's actually a hybrid between an Integra LS block and either an Integra GSR head or a Civic B16a head. This combination creates incredible power on both the top and bottom ends. By no means is this an "easy" swap. You will have to wire in the VTEC, mate the head and block together and fabricate some special parts. But any lengths you go to in order to get this engine will be paid off 3 fold in the end. The LS block is extremely torquey, in fact, produces the most torque out of all the B-series engines. Combine that with the peppy, high horsepower VTEC head and you have a strong motor that pulls hard from 2000 to redline. If you want to go fast, this is definitely one way to go. New products show up specifically for this motor every day, and many tuning companies have them in their own cars, like 5zigen for example. You can expect 1/4 mile times in the low 14, high 13 range stock. With mods who knows, but this engine earns the name FRANKENSTEIN!
