2nd Gen Integra - B-series Swap Info Swapping a B-series motor into the 2nd Generation Integra is much easier when compared to the first generation swap. Fortunately for Integra owners, Honda made the B18A standard in every Integra. Combine this with standard rear discs and a more refined shell makes this car an excellent candidate for a swap. Several motors are available and make for good swap candidates, including the first generation B16A, which was offered in the JDM Integra XSi and CRX SiR, B17A1, B18C1 and B18C5. Fortunately, mounts from Hasport will not be needed for these swaps, however, a cable transmission will make this swap easier. Finally, the OBD of the vehicle is another aspect of this swap that has to be addressed...

If you did an OBD1 B18C or B16A swap into your 5th gen Civic VX, chances are you are throwing code 41 if you haven't converted the Oxygen sensor over to operate in the 4-wire way your ecu (like a p28, p30, or p72) is expecting. If you have an automatic ECU, read this first: Convert a Honda ECU from Automatic to Manual Situation: OBD B-series Swap into EG Civic VX Civic EG VX harness used on B-series engine A b-series will not run off the 5-wire, mostly for the computer reasons. First, pick up a 4-wire o2, found in just about every other civic besides the 1 or 2-wire equipped ones. These can be found at the local auto parts store pretty cheap. Now you have a 4-wire ecu and O2, but a 5 wire harness. The easiest way to do this...

How to Test a VTEC Solenoid Disconnect the 1P connector from the VTEC solenoid valve. Measure resistance between the terminal and body ground. Resistance: approx ~30 ohms If the resistance is within specifications, remove the VTEC solenoid valve from the cylinder head, and check the VTEC solenoid valve filter for clogging. If there is clogging, replace the engine oil filter and the engine oil. If the filter is not clogged, push the VTEC solenoid valve with your finger and check its movement. If VTEC solenoid valve is normal, check the engine oil pressure.

1st Gen Basic B-Series Swap Tech Covering the basics Integra’s between 1986 and 1989 came with d16’s that are essentially ZC’s. Now, using basic logic it becomes clear that swapping in a B-series motor is not a bolt in affair. However, Hasport has currently announced that they do have a mount kit for this motor and other companies will certainly follow. The most common engine to use is the first generation B16, but any B-series motor will fit. What makes this swap very intriguing is the Integra’s lightweight shell that weighs around 2200lbs. Compared to newer heavier Integra’s the power to weight ratio can become very advantageous. Here is what you’ll need: * ECU: PR3 * Custom Air Intake * Throttle Cable from...

If you bought a CX or DX civic with a 1-wire o2 sensor, you're going to have to convert to a 4-wire to run a b-seires ecu, and most of the "top of the line" d-series ecu's like the p28. First things first, you need to physically buy a 4-wire o2 sensor. you can't send a heater signal to a device which has no heater circuitry and expect it to work :D Wires on 4 wire O2: WHITE: Signal Wire GREEN: Signal Ground 2 BLACK: Both black wires are the heater circuit wires. Using a P28 ECU (and should work for most obd1 ecu's with 4-wire controls) Run O2 Sensor signal (white) To D14 Run O2 Sensor signal Ground (green) to D22 (or any good Ground) Run O2 Sensor Heater Circuit Control (black) to A6 Run the other black heater circuit power wire...

First Gen B16A into 5th Gen Civic Overview In this article I will explain how it's possible to put a First Gen B16A into your 92-95 Civic. First, it's important to remember that this setup will be OBD1. The only difference with this swap is using the first Generation B16A long-block, which can be purchased from online distributors for around 400-600 dollars. Next, you'll need to find B-series equipment for the following: a hydraulic transmission, OBD1 ECU, OBD1 Distributor, OBD1 Saturated injectors, and use your original OBD1 wiring harness in your obd1 civic. Wiring As far as the wiring goes, if you have a VX or Si you'll need to lengthen the wires for VTEC and add a wire and plug for the knock sensor if you're running an ECU...

California Smog Guide California has some of the toughest rules for vehicles in the United States. The CARB (California Air Research Board) is the governing body that oversees environmental factors for the state including vehicle emissions. Swaps are not always allowed and can get you in trouble with authorities, or even have your car impounded or crushed. Before you change out your engine, be sure you understand what you can and cannot do from a legal perspective. Some of these links will help inform you of the process.

JDM H23A Bluetop Swap Guide I've seen checklists for swaps like this but I thought I would give my .02 from having done this personally. For the H23a into a 93-97 accord it's not just about a motor and a car, in a lot of ways there's kind of a theory-crafting that goes into it. For this swap, the plan was always to run it OBD1 off of a P28 ECU. So consider, H23a Bluetop motor specs per wikipedia (take it for what you will) Found in the Japanese 1998-2002 Accord Wagon SiR (CH9). It produces 200 PS (147 kW; 197 hp) @ 6,800 rpm & 163 lb·ft (221 N·m) @ 5,300 rpm and comes with a "blue top". Found in the Japanese 1998-2002 Accord Wagon AWD (CL2). It produces 190 PS (140 kW; 187 hp) @ 6,800 rpm & 163 lb·ft (221 N·m) @ 5,300 rpm and...

OBD 2 B18C1 into a 5th gen EX Question: I have an OBD 1 Civic. Does it make a swap much harder to do by choosing an engine that is obd2? For example, putting a 1999 B18C1 into my 95 Civic EX coupe? I know of the wire harnesses that can be gotten for this kind of swap but i read on a site that it is not recommended?? What are your thoughts on this? Answer: If you get the wiring harness with the '99 GS-R swap all you need to do is drop it in, plug the engine harness in, and add wires for the VTEC solenoid, knock sensor, and VTEC pressure switch. Get an OBD1 GS-R ECU. It plugs right in. For the IAB you will need to move A20 to A17. Since you will be using the OBD2 engine harness and an OBD1 GS-R ECU you will need to cut the black...

SiR 2 into an EK So, you didn't listen when everyone on the board said, "dude, get a motor with the same obd as your chassis" huh? Well, there is some hope for you. Using the mounts and basic swap info as listed in our Basic 6th Gen Swap Guide, you are going to need a bunch of other things as well. This does not hold 100% true for the B18C into the EK though. This article focuses on a B16A3 or B16A SiR2. Here's a basic parts list from other cars, in addition to your donor car and your recipient car. You will need the following parts from a del Sol VTEC: * Intermediate shaft * A pipe * A/C belt (if you use A/C as mentioned in the linked article above) * Alternator belt * Axle seals * Upper and Lower radiator...

Everything you want to know about the b20 motors http://www.honda-tech.com/zerothread?id=460954

I have an H23 in my 94 lx 4door and i kept my a/c. Here's how i did it. First you will need to leave the a/c compressor hooked up - do not disconnect it. You can work around it. When you get the engine out, pull the a/c bracket off your old block (F22) then put it on the Prelude motor. It will bolt right up. Then you will use the alternator bracket from the h23 and the power steering bracket from an h22 and all your stuff from the accord will bolt up including a/c alternator power steering pump You will need the belt for an H23 motor to run the alt and a/c compressor Then you will need to check the fitment for the power steering belt. Take the car to a local auto parts store so you can keep trying different sizes- it is a...

No matter HOW a car is powered - NA, Super, Turbo, NOS, ZEX, Propane, or anything else that involves a transmission with gear reduction, a car will ALWAYS accelerate the fastest with the CLOSEST transmission. Saying an LS tranny (long geared) is good for boost is simply wrong. "staying in boost longer" is also a false statement. If you have traction problems, solving them with a longer tranny is the WRONG way to do it. Tires, suspension setup, and other forms of traction enablers are what you should be looking at- not slowing yourself down. Taking the differential out of the equation for this - assume all can be replaced with a limited slip. This is focused on gearing only. So, here's my recommendation, and your needs and...

B20 Tech - Swapping a B20B/B20Z in a 5th Gen Civic Overview In 1997, Honda began offering the CRV as part of its new model line. While most of us weren't interested in this vehicle, those interested in building the ultimate hybrid were delighted when they found a B-series motor under the hood. While there are some adjustments and changes that need to be made, this motor comes rated with around 140 torque and 140 horsepower making it a very viable candidate for swap. Here is what you'll need 1.ECU: P75(B18B) Note: Some P74's will work (obd1 variants) as well, but P75's are a sure thing for the most part 2. B-series throttle cable specific to motor, B17A or B16A throttle cables will both work Note: B18C throttle cables are different...

Editors note: Originally published by Adam P. on his sub-site, Change Honda ECU from Automatic to Manual. Preserved here in the forums going forward. This guide will help you identify and change or convert your automatic ecu to a manual version. Honda Manual or Automatic ECU Identification First, let's find out if we have an automatic, or a 5 speed ECU. If you don't want to plug it in and throw code 19 (automatic trans lockup solenoid) to find out it is an automatic ECU, then look at the code on the side. If the second to last number is a 5, then you have an automatic ECU (for OBD-1 USDM ECUs). If the 2nd to last # is anything but a five you have an ECU for a 5 speed. If you have a jdm obd-1 ecu, look at the last 3 digits: 900 or...
