Tensioner Conversion TENSIONER CONVERSIONThis seems to be a hot topic for the H22 owners out there. Here is a step by step "how to" conversion to the more reliable H23 (manual) style of tensioner. The H22a block used, is obviously a "mock-up", so don't be critical of the missing pieces. This conversion can be done in the car, but in this case it was done out of the car for illustration purposes only.Parts list:13404-PT0-004 - ADJUSTER COMP., BALANCER BELT13415-PT0-000 - BRACKET, BALANCER BELT ADJUSTER14510-PT0-004 - ADJUSTER COMP., TIMING BELT14516-PT2-000 - SPRING COMP., TIMING BELT ADJUSTER14521-P14-A00 - PLATE, ADJUSTER90014-P14-A00 - BOLT, TIMING BELT ADJUSTER BASE90015-PT0-000 - BOLT, TIMING BELT ADJUSTER SPRING90016-PT0-000 - BOLT, TIMING BELT ADJUSTER90140-P14-A00 - WASHER, PLAIN (11MM)LINK to write up

Axle FIX Write up by: slick jr LINKI recently did an h22 swap in a 96-00 model civic coupe and i have found a way that allows u to drop ur car without having any axel issue. Now this is my solution and do try if u so please but i bear no responsibility if not done right.Now the problem we have when dropping our car too low is the axle grinds. Now previously I thought that it’s because the axles did not have any room to play. Further investigation reveled something else, I jacked up my car remove the shocks and jacked up the hub to simulate what happens when the car is lowered and started the car in gear.What this reveled is that the source of the grinding is in the inner CV joint and that the car was doing a hoping motion when it rotate which explains the grind feeling. Now this is the tricky part, here is what happensThis is how the civic inner cv joints look or similar. (figure 2)Now with the h22 wasp where axles are positioned at a sharper angle while the cup remains straight (axles angled up and back). Now u noticed the cup has three groves to accommodate the three bearing. The problem is the raised area between the groves. See the circled area: (figure 3)Now what happens is because of the angle of the axle the outer portion of these raised areas (circled area) would hit the shaft of the axle causing the grind. If your car is extremely low this happens constantly, a little low this happens when ever you hit a wave or hump. So before your only option was to raise the car which giving the shaft a better angle away from the circled area.How do we fix this? Now I didn't take a picture of mine cause I was tired of the grinding and i was just trying this at the time after trying everything else.The solution is to separate the inner CV joint by just removing the boot and slide the shaft and bearing out, yea that simple. Now here is what u do take the cup to a machine shop and have the grind the outer portion of the raised area down to meet the circumference of the cup. See shaded portion in picture. (figure 4)Now the outer circle (circumfrance) represents the outer rim of the cup. The shaded area represents the area that going to be grinded down to meet the rim of the cup. Now originally the outer portion of the raised area is already slightly tapered (has a slight slope). DO NOT GRIND ANY FURTHE BACK THAN WHERE THE ORIGINAL TAPERED END OF THE RASED AREA STARTS. You are not rrinding it flat your grinding it in an angle to the rim of the cupI have dose this a few months now and it works perfectly, no grind no bind and no it will not slide out or slip. My car has been on the track quite a few times with no issueI tried my best to explain let me know if anything is not clear

Ecu Code Diagnostic WARNING: Use this information at your own risk. JDMH22 or any of its affiliatesis not liable for any damages or injuries.Extracting the Codes1. Turn the ignition off.2. On the passenger side of your car, under the dash beneath the glove box, you will finda green cover above the kick panel that houses a blue connector that has two wires.3. Using the piece of wire or paperclip, jump the blue connector so that you connect thetwo wires together. Basically stick one end of the paperclip or piece of wire into one prongon the connector and stick the other end of the paperclip or wire into the other prong.4. turn the key to the IGN position and watch your CEL light. It will illuminate in a series offlashes.Reading the CodesYou will notice that there will be LONG flashes and SHORT flashes. All of the ECUtrouble codes are two-digits. LONG flashes determine the TENS digit by the number oftimes it flashes, and SHORT flashes determine the ONES digit by the number of times itflashes.ie. LONG-LONG-LONG-SHORT-SHORT-SHORT-SHORT-PAUSEis the trouble code: 34ie. LONG-LONG-SHORT-PAUSE-LONG-LONG-LONG-LONG-SHORT-SHORT-SHORTPAUSEis the trouble code: 21 and 43Once you have determined the codes, you can simply remove the paperclip or wire fromthe connector and replace it back in the green housing.You can clear all the codes from the ECU memory after your fix the problem bydisconnecting the negative battery terminal for 15 sec.Tell your friends to visit www.speedinnovations.comCODE VEHICLE DEFINITION186-98 Civic97-98 CRV85-98 Prelude94+ IntegraOxygen Sensor "A" (Primary) defective circuit or unplugged /defective sensorcode can be disabled on a Speed Innovations tuned ECU2 86-87 Civic Oxygen Sensor "B" defective circuit or unplugged / defectivesensor86-98 Civic97-98 CRV MAP Sensor (Manifold Absolute Pressure) defective circuit or3 85-98 Prelude94+ Integraunplugged / defective sensor488-98 Civic97-98 CRV85-98 Prelude94+ IntegraCKP Sensor (Crankshaft Position Sensor) defective circuit orunplugged / defective sensor586-98 Civic*97-98 CRV85-98 Prelude94+ IntegraMAP Sensor (Manifold Absolute Pressure) mechanicalproblem / disconnected piping* not 94-95686-98 Civic97-98 CRV85-98 Prelude94+ IntegraECT Sensor (Engine Coolant Temperature) defective circuit orunplugged / defective sensor786-98 Civic97-98 CRV85-98 Prelude94+ IntegraTP Sensor (Throttle Position) defective circuit or unplugged /defective sensor886-98 Civic97-98 CRV85-98 Prelude94+ IntegraTDC Sensor (Top Dead Center) defective circuit orunplugged / defective sensor986-98 Civic97-98 CRV85-98 Prelude94+ IntegraCYP Sensor (Cylinder) defective circuit or unplugged /defective sensor* invalid code for throttle body injection Hondas** invalid code for V6 engines1086-98 Civic97-98 CRV85-98 Prelude94+ IntegraIAT Sensor (Intake Air Temperature) defective circuit orunplugged / defective sensor1286-98 Civic85-98 Prelude94+ IntegraEGR Lift Sensor (Exhaust Gas Re circulation) defective circuitor unplugged / defective sensor* invalid code for non-equipped EGR valve vehicles1386-98 Civic97-98 CRV85-98 Prelude94+ IntegraBARO Sensor (Atmospheric Pressure) defective circuit orunplugged / defective sensor1488-98 Civic97-98 CRV88-98 Prelude94+ IntegraIAC Valve (Idle Air Control) defective circuit or unplugged /defective sensor1588-95 Civic88-95 Prelude94+ IntegraIgnition Output Signal missing or defective ignition outputsignal88-95 Civic16 88-85 Prelude94+ IntegraFuel Injector System defective circuit or unplugged / defectivefuel injector1788-98 Civic97-98 CRV88-98 Prelude94+ IntegraVSS (Vehicle Speed Sensor) defective circuit or unplugged /defective sensor19 88-95 Civic94+ IntegraAutomatic Transmission Lock Up Control Solenoid Valvedefective circuit or unplugged / defective solenoid valvecode can be disabled on a Speed Innovations tuned ECU2088-98 Civic97-98 CRV92-98 Prelude94+ IntegraElectrical Load Detector defective circuit or unplugged /defective sensorcode can be disabled on a Speed Innovations tuned ECU2192-95 Civic93-95 Prelude94+ IntegraVTEC Solenoid Valve defective circuit or unplugged / defectivesolenoid valve* invalid code for non-VTEC engine** invalid for V6 engine2292-98 Civic93-98 Prelude94+ IntegraVTEC Oil Pressure Switch defective circuit or unplugged /defective oil pressure switch* invalid code for non-VTEC enginecode can be disabled on a Speed Innovations tuned ECU2396-98 Civic92-98 Prelude94+ IntegraKS (Knock Sensor) defective circuit or unplugged / defectivesensor* invalid code for V6 enginecode can be disabled on a Speed Innovations tuned ECU30 92-98 Prelude94+ IntegraAutomatic Transmission Signal: "A" / SEAF / SEFA / TMA orTMB defective circuit or unplugged / defective sensor* invalid code for 199631 92-95 Prelude Automatic Transmission Signal "B" defective circuit orunplugged / defective sensor4192-98 Civic97-98 CRV90-98 Prelude94+ IntegraPrimary Oxygen Sensor -
