ROCK THE D

Note: I'm not trying to start a debate over people who can afford or love their B-Series Engines, just trying to show people why they might want to stick with their single cam slammaa

Now this is going to be a General Idea nothing of course is going to be exact because its just not possible.

Also these are general prices of swaps and info, this is not including the price of aftermarket parts, labor, shipping and anything else you might need!!!

Basics of Engine Swaps: what fits in what

Overview

In order to properly cover every aspect this section will be broken down into many sections. First, its important to decide what you’re goals are. If you’re interested in running 15 second quarter miles without hassle or complication then finding a D16 is probably your best bet. Some of us are interested in running 11 and 12 second quarter miles. For this type of performance it’s important to plan every detail so that the engine is capable and reliable when asked to perform. Another part of planning that should be done before the swap begins is whether or the engine will be naturally aspirated or have forced induction. These are all questions that need to be answered before the swap so that you’re satisfied when everything is complete.
Now we all no that in able to run a D16 motor NA you should pretty much show to get that much power and Speed you are not going to Be able to just drop it in a 90 Crx Si and run it daily on 91 pump gas. So lets just get that out of the way for all "Fast and The Furious" Believers.

Finding the Proper Engine:

There are many engine choices for each vehicle so we’ll cover all of them. First it’s important to understand that On Board Diagnostics play a large role in which engines are easiest and recommended. All Honda’s 1991 and earlier are considered OBD 0. This means that the engines don’t utilize any oxygen sensors and have little in the way of emissions control. Next there are OBD 1 engines that are found in all cars from 1992-1995. These vehicles have traditionally been the best platform for the most “factory-like” hybrids. Finally, anything from 1996-1998 is OBD 2. 1999-2000 is OBD 2b. It’s also important to remember that its only legal to swap in engines of the same or newer OBD series. That is to say that an OBD2 engine can be placed into a 1988 CRX legally and without many wiring problems. Consequently its illegal in most states to use OBD 0 engines in cars that should have OBD1 or OBD2 power plants. Of course there are people who disregard these laws and regulations but its not recommended or necessarily that easy.

4th Generation:

1. ZC,JDM D15B, D16Z6/Y8 : Completely Bolt-In Swap. On the Z6 and Y8 you will have to switch out engine mount from factory EF engine over to New z6/y8 Engine. Now you can Easily get one of these engines if you know your basic resources.
Transmission: Use ZC/ Now for Tranny of course just use 88-91 Si Tranny for best Gearing. You can use Dx 5spd but you do have different final Drive so thats why alot of people try to get there hands on SI tranny.
Shift Linkage: Use stock Civic/CRX shift linkage
Axles: Stock Civic/CRX

OBD1-OBD2 Engine Swaps into 89-91 Civic/CRX

To install an OBD1-OBD2 engine into your 4th Generation Civic/CRX the following adjustments will need to be made. First, if your car has dual point injection a conversion will need to be made to port injection. All Integra's 1994 and up and Civic's 1992 and up all use hydraulic transmissions. Therefore its not compatible with 4th Gen Civic's because these vehicles have cable transmissions. To complete the swap a B-series cable transmission will need to be used or a cable-hydro transmission conversion will need to be made. The left side bracket needs to be changed to a 1990-1993 Integra bracket.
For the ECU, it is best to use the ECU which belongs with the engine. Several wiring adjustments will need to be made to make the engine run correctly.
For LS-VTEC's, CRVTEC's and other Frankenstein's it is easiest to use the ECU that corresponds to the distributor and head. There are also reprogrammed ECU's which can be considered.
