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 manufactured in vehicles up until 2001. The first Generation ZC's were offered from 1985 through 1987. These engines can be found in 85-87 JDM Civics and JDM CRX Si's and were very similar to the 1986-1987 US Integra engine. It's worth noting that this...

CONS *h22a is 60lbs heaver than a b18c with a/c power stearing ext.. *parts are more money, and harder to come by for cheep like its b16/18 conter parts *if you want to put forged pistons in you have to resleave the motor, i will explane why if you want me to but for now we will just leave it at that. *beacuse you must resleave for the pistons it make running anyhting over 9psi fairly expensive and a lot of work. *it is a little bit of a tricky swap to get in the bay of a civic. *to turbo you have to get slim radiator fans *when you shift a h22a with a stock transmition at redline you fall about 200 rpms out of vtec, so a vtec controler is a great idea, or go a little deeper in to the redline (indicated redline is 7,400...

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...

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.

EF Swap Guide Original: Ben Ogle (Updated and fixed bad links by HondaSwap.com Staff] So you have an EF/ED. Chances are that it is slow, especially if you ended up with a DX, LX, STD or some other long-geared, gas-saving, dual point model. So this guide is here to help you decide how you want to make faster without the aid of forced induction (well, you can go that route too but its not covered). If you are a newbie read EVERYTHING here. That way you will spend less time asking questions on message boards. Also, I didn't feel like reiterating everything in every specific motor section so read at least the first few before you scroll down to the motor you want to get. B-series These are by far the most popular swaps. They are fairly...

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...

OBD1 B-series Wiring Guide Wiring an OBD1 VTEC B-series into a 92-95 Civic The most common cars for swaps are the EG-chassis line of Civics. Since there were way more base models produced than EX/Si models, chances are that your car is not already wired for a VTEC swap. Here's a quick chart of what to check when wiring in your 94-95 Integra B18C1 or 94-95 del Sol VTEC B16A3 into your EG. Most jdm motors will also follow this guide, but some changes will be made to your stock harness for it to work properly. Ensure that the following are all hooked up before you get any deeper into trying to figure out what's wrong. The B16A/P30 as well as the B18C5 if using an obd1 electronics setup will need 6 wires while the B18C1/P72 and...

Anything can fit in any car with a hacksaw and all kinds of money... but to keep it simple, try your best to stick to the above. It will save you wiring problems and will most likely be cheaper than trying to, for example, stick a b16a SiR1 into an EG chassis vs. just buying the SiR2 in the first place. I'm sure i missed a...

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 much chassis denting, and while that may be cool to do on a race car, it makes your bay look like crap and can lead to a weaker engine bay. In addition, you wont have room for A/C or power steering if those options are required by you.The other motors...

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, pretty much the entire internals and external bolt ons couldn't be more different. The k20a2 has higher compression pistons, more agressive cams, dual valve springs, and a tri-Y header with larger primaries than the k20a3. If that wasn't enough, the...

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...

The mad tyte JDM h22a swap for 92-95 EG Civics (should work for 92-00. Edited to include EK 96-00 wiring): Seeing lots of h22 swap questions and misc B.S h22a threads, I decided I'd make a thread here for Honda Swap. An almost complete h22 swap guide if you will. I've done the swap and regret not taking pics of pulling and installing the h22 in my 92 hatch. What you'll need: H22 Motor and trans p13 ecu(or chipped ecu like a p28) Shifter box and cables Swap mounts Injector resistor box(or do Bizzar's DSM injector resistor mod from d-series.org) Accord(94ish) Driver's side mid shaft 90-93 Integra axles + the inner CV snout of a 94+ Prelude or Accord(Explained later) Spare CV grease and boot clamp After market radiator(suggested) slim...

How to Wire VTEC This is something that I see come up, and sometimes people get confused by the written instructions, so here's one with pics. This can also be used for wiring just about anything you need, like a knock sensor, IABs, o2 sensor, whatever. I HIGHLY suggest have a manual with a wiring diagram and the pinouts, for your ECU, you don't want to screw up now that your motors in right? Ok, assuming you have a vtec motor in a non vtec car and you need to wire in vtec y0! here it is... Our demonstrator model is a 95 CX with a OBD I B16A. So you have your motor in the car, and you are using XXXX engine harness, as long as you have the plugs (usually come with motors harness, even JDM, just remove the whole thing from...

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...

Basics of Honda Engine Swaps: What Engines Fit (easily) in What Chassis Overview In order to properly cover every aspect, this article will be broken down into section based vastly on generation of vehicle. 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 B16 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...
