Ok Honda D series info: The Honda D engine is used in a variety of compact Honda models, most commonly the Honda Civic, but also used in the Integra, Logo, CRX, Stream and others. Displacement ranges between 1.2 L and 1.7 L, and the engine is available in SOHC and DOHC versions. Some SOHC models are equipped with VTEC. Power range started from 62 hp (currently the smallest engine uses a 1.4 L 90 hp engine, code D14A4) to 135 hp. The D-series was introduced in 1984 and ended production in 2005 with the introduction of the 8th generation Honda Civic. Hot Rodding the D series 101 Although the availability of used D-series engines at low prices makes it somewhat popular among those who modify it for high performance (as well as a popular item for swapping into earlier or less powerful Civics for an instant and trouble free power upgrade), the unmodified engine won't survive quite as much power enhancement by use of such external modifications as turbochargers, superchargers, or nitrous oxide as the more powerful, somewhat more robust, and much more expensive B-series; the Achilles heel of the D-series seems to be the connecting rods, which will withstand a substantial and noticeable increase in power up to a certain point, but will break if that limit is exceeded. Generally, a D-series motor can handle up to about 200 bhp. Of course, the connecting rods and other internal parts can be replaced with more durable aftermarket parts which will survive almost any amount of power desired, but some people choose to swap to a B-series motor instead in order to avoid the potential risks of engine building. In all practicality though, the B series is much more expensive to swap in than most D-series engine builds and forced induction or nitrous combined. The D-series also has the ability to swap some parts between different motors and among some B-series parts as well. High compression OEM pistons are a quick way to gain horsepower in a naturally aspirated motor. All D-series motors run the same bore (75 mm) however, most factory motor variations (i.e. d16a1, d15b7, d16y7) have used a different piston compression height as well as a different dome or dish. In general, the older D motors have a higher compression height and a larger combustion chamber which create around a 9.1:1 - 9.4:1 compression ratio from the factory. The newer varients have slightly lower compression height combined with a much smaller combustion chamber to create a compression ratio of 9.4:1 - 9.9:1. Now if you combine a older d16 motor's piston with that of a newer d16 head you can end up with a compression ratio like 10.78:1 with no other work(i.e. D16A1 piston, D16A6 head). There are a few websites that have compression ratio calculators for Honda motors. ·D15, D16, and D17 cranks all have different main bearing diameters. ·D16 and D17 rods all have the same major dimensions. The D15 rod is shorter (in general) and has a smaller bearing size, although the wrist pin bore is the same. ·D15Z1 and D15B motors have a rod that is the same length as a D16. Other then the rod length the rest of the bottom end is D15 spec (i.e. rod and crank bearings). ·The B18A/B Rod has the same bearing bore as a D16. It is 0.044" wider, so the rod has to be shaved down for use in a D16/17. The wrist pin bore is larger so a conventional D15/16/17 piston can only be used with a bushing in the rod. ·There is a D16 motor that runs on compressed natural gas (96-98 Civic GX). The pistons from that motor are 12.5:1 compression. The wrist pin bore is the same as the B18B rod for years 96-98 only. Mini Me: One of the most popular and effective methods of achieving greater power from a D-series motor is replacing the cylinder head with one from a more powerful D-series motor. This is usually done between D16A6 and D16Z6 or D16Y7 and D16Y8 engines. The Z6 and Y8 heads are VTEC (Variable Valve Timing and Lift Electronic Control) equipped, and increase horsepower significantly over stock levels. This operation is known as a "Mini Me" or partial swap. Mini Me's are popular because they offer a substantial performance upgrade, as well as introducing VTEC, to the motor at a relatively low cost.

Good freakin write-up:thumbup::thumbup: Someone should send a link of this to 2000civichatch,...nevermind. I'll just do it
arrite i jus got a d16z6 Vtec for my 95 coupe... i wanna turbo that shit but dnt knw how many psi i can run..plz help me out
Honda Civic I always love Honda cars. That is why when I decided to get a commuter car for my trips to and from work, I went to a dealership. I told them I needed a vehicle that would not cost me too much cash and would be affordable to keep up. They pointed out that the Civic is good and has gas mileage. It is a very reliable car. I was able to get the Honda Civic at a fantastic deal and am very happy about this.
