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...
 
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...
 
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...
 
i made this write-up in hopes it would be a sticky or put in the swap articles if anything i write is WRONG please let me know tell me what you think
 
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...
 
Honda OBD1 to OBD2 Alternator Wiring Guide If you don't have an obd1 alternator, a quick re-wiring of the obd2 plug pigtail can help save you some money. The wiring process is fairly straightforward. obd2 alternator plug__ obd1 wire harness black with yellow strip__ black with yellow strip white with blue strip __white with blue strip white with red strip__ all blue wire white with green strip __white with yellow strip
ZC Identification Guide The ZC engine is one of the hardest to identify because there are many different versions of this engine. Honda offered this engine in both single and dual overhead cam designs, as well as fuel injected and carbureted versions of these. This article distinguishes the different versions of the ZCs offered. Hopefully this will separate the facts from the myths. The First Generation ZC ZC's were first offered in Civics and Integras in 1985 and were still being...

Assuming you will be using the same vintage drivetrain as the car here are the Honda part numbers for the 3 main mounts you will require. All mounts from 99-00 Honda Civic SiR (US Si) Note: The transmission mounts are for the 99-00 SiR tranny. If someone could confirm that they would also fit the Integra transmissions it would make this thread more usefull! the T-Belt mount will fit any B Series engine however.) Timing Belt Mount Part # 11910-P30-000 (Mount bolts to the block underneath...
 
no need to re-invent the wheel on this one. The IACV info is below the pinout for the 2 version of obd2's OBD2a OBD2B
There has been a lot of talk about how to do this lately-- so time for a FAQ :) Chances are, if you are even running yet, you are throwing code 41 first, get some basics as taught by pills: Convert a Honda ECU from Automatic to Manual now, here's what your dealing with.... First off, this is considering a b-series swap done using the VX harness. a b-series will not run off the 5-wire, mostly for the computer reasons. so, first thing to do is to pick up a 4-wire o2, found in just...
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...
Non-recommended Swaps Not all motors work well, or at all, in every chassis. In addition, some DO fit and work, but are still not recommended. Most of this comes down to OBD again. If you haven't read our article on OBD yet, do so before reading the rest of this article. 4th gen * D16Y7/8 * B16A2 (USDM) * B16A3 * 96+ B18C * 96+ B18B * B18C5 * any H-series * any C-series motor We don't recommend these motors for several reasons. The H-series will require...
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...
With the new K-seires motors around us, there is a need for new information about the motors themselves. This article won't deal with swapping it in any car- but rather comparing the two variants. the k20a3 is found in the 02+ civic si and the base model rsx and have a 5 speed tranny. the k20a2 is found in the rsx type S and comes with the 6 speed tranny. The k20a2 and the k20a3 share the same 2.0-liters of displacement, bore/stroke, block, head, valves, and intake manifold. However...
I started the swap today after school had been canceled. Thus far, I have the new pedals installed and the Shift Lever (A/T) out. This is for a 90 Acura Integra. First things first get the POS auto out of there and sell it on EBAY! Sell everything you dont need, cuase you wont be able to use it. When mounting new MANUAL transmission you need to get 3 12x1.25x60mm bolts and get a bit more than 1 1/4" of shims for each bolt just so you have extra shims if you end up needing them. (Go with 4...

In this article, we will help you to pick out the clues as to which motor is which, and which one you should get for your B16 swap. Although I just noted that there are 4 classes of B16A's, we can break that list down into two groups. Our new grouping...

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...
