SPECIAL NOTE: Because there are somany different makes, models, and coun-tries that we sell kits to, we are unable tosupply a new intake gasket or throttle bodygasket with your kit. Most of the time thegaskets can be reused, but, for safety rea-sons, we recommend buying new onesfrom your local Honda dealer before start-ing the installation. If you do not have ashop manual, buy one now! It is good tohave one for any repairs now and in thefuture.

TOOLS NEEDED: 8, 10, 12, 14, 17, and30-mm socket and wrenches, a 22-mm(7/8”) wrench, a 30-mm (1-3/16”) and an11-mm (7/16”) socket or wrench, 8-mmallen wrench, phillips and straight bladescrewdrivers, vice grip pliers, and a timinglight. You will also need an electric or airimpact gun to remove the alternator pulley(using the 30-mm socket). Most of thesetools are available at your local hardwareor auto parts store. A soldering gun is notrequired for the few wiring details, as wesupply crimp connectors, but solderinghas a better long-term serviceability.

Jackson Racing Supercharger Systemsare designed to be installed by individualswith good mechanical sense and with theproper tools. Use your best discretion!The supercharger DOES NOT require abreak-in or warm up period. However, toprolong engine life, it is recommended thatthe engine be properly warmed up beforeoperating under maximum boost.

WARNING: Once the installation is com-plete, CHECK AND RECHECK ALL fuelsystem connections for possible leaksbefore operating the vehicle. 92-octanegasoline (or higher) is required when run-ning a supercharger!

READ THESE INSTRUCTIONS THOR-OUGHLY! Follow the instructions STEP-BY-STEP, and your installation will betrouble free. If in doubt, CALL 1-888-888-4079. We suggest that as you proceedthrough the installation, you should reada few steps ahead in the instructions soyou are certain to catch all notes andwarnings.

During this installation process, you willreuse some parts or hardware and notreinstall others. It is recommended thatyou make space for those that you willreuse, and a separate space for thosethat you will not reinstall. In addition, youshould save the parts that will not getreused in case you ever have reason toconvert the engine back to stock.

Enclosed are a set of labels that we sug-gest you use to label the electrical con-nectors that you will be unplugging.

If the vehicle has over 15,000 miles onthe fuel filter, a new fuel filter will berequired. A new fuel filter is available atyour local Honda dealer. Always use gen-uine Honda parts.

This is also a good time to change youroil and filter as the oil filter must beremoved for installation of the super-charger on models with an oil coolermounted under the oil filter (some non-U.S. vehicles). It is a good idea to startdraining the oil, oil filter, and coolant first.This will allow for all fluids to drain com-pletely before you start working under the car.

INSTALLATION INSTRUCTIONS

1. VERY IMPORTANT! Disconnect thenegative battery cable. If you have acoded alarm on your radio, retrieve thecode before removing the negative cable.On our test vehicle, both the alarm andradio codes were on a card received atvehicle purchase.

2. Put your car on jack stands.

NEVER WORK UNDER A CAR NOTSUPPORTED BY JACKSTANDS ORRAMPS.

3. Drain the cooling system as you will bereplacing some hoses and the intakemanifold. Note: When draining thecoolant, carefully blow compressed airthrough the coolant bleed valve locatednear where the top radiator hose con-nects to the engine block. This valve issometimes omitted depending on produc-tion runs. Using a 12-mm wrench, openthe valve and carefully blow air into thevalve to purge the block and coolanthoses. This will keep you from gettingdripped on while working under the car.

4. Remove the large diameter rubberhose between the air box and throttlebody. Loosen the clamp at the throttlebody with a phillips head screwdriver andslide it off. Disconnect the double metalpipe assembly by removing the pinch clamp.

5. Remove the other end of the doublemetal pipe assembly by disconnecting itfrom the top of the valve cover. This hosewill get replaced by a 4" piece of venthose. The two other lines connected tothe assembly are water hoses. Leavethese attached until a later step.

50. Locate the IAC valve wiring harnesswith wire colors yellow with a black stripeand black with a blue stripe. Get theextension wire with same wire colors fromthe kit. Cut the wire to the IAC valve andsolder or crimp connect in the extensionprovided in the kit.

51. Remove the one inch O.D. heaterhose that has the metal pipe section inthe middle. NOTE: Where this hose con-nects at the firewall, the fitting is thin-walled copper and will deform ifsqueezed. To remove the hose, slice itlongitudinally along the hose to the end ofthe fitting and slip the hose off the fitting.This assembly will not be reinstalled.

52. Install the new 5/8 x 18" heater hosefrom the fitting on the engine to the fittingon the firewall. Clamp the hose ends

with two new #10 clamps provided.Illustration 3

53. The oil cooler fitting in the main waterpipe needs to be indexed (or pointed) ina horizontal direction back towards thefirewall. On some models we have foundthat the fitting points above horizontal,slightly uphill. If your fitting points abovehorizontal, CAREFULLY insert a largepunch or screwdriver into the fitting andgently apply pressure until the water pipeis at least horizontal. If the oil cooler fit-ting is pointing a little downhill, that isacceptable.

54. Loosen the power steering pump.Remove the belt. This belt will be rein-stalled.

55. Loosen the tension pulley for the airconditioning belt and remove the belt.This belt will be reinstalled.

56. Remove the factory, 785-mm alterna-tor belt. This belt will not be reinstalledand will be replaced by the 800-mm beltsupplied in the kit.

without interference. Illustration 7

86. Locate the original vacuum canisteron the under side of the factory intakemanifold. Remove the black vacuumswitching (IAB) valve from the vacuumcanister. This switching valve will notserve any function, as there will be novacuum hoses attached, but MUST beplugged in. Plug the switching valve backinto the main wiring harness and zip tie itto the main wiring harness toward driver’sfender out of the way.

WARNING! Do not smoke during these procedures.

87. Remove the fuel filter from the fire-wall. First disconnect the hard fuel line.Do NOT move or bend the hard fuel line.Remove the two 10-mm bolts and theone 10-mm nut holding the fuel filterbracket to the firewall. Remove the fuelfilter and bracket assembly. The fuel filterand bracket will be reinstalled.

88. Remove the throttle cable stabilizerbracket mounted on the center of the fire-wall by removing the 10-mm headed bolt.The previous two instructions will provideroom to insert the supercharger downinto the engine compartment once thesupercharger intake manifold is in place.

89. Locate the air temperature sensor onthe factory intake manifold and install iton the Jackson Racing intake manifold.

90. Locate the pressure switch suppliedwith the kit. Wrap the threads of the pres-sure switch in teflon tape. Install it on the

Jackson Racing intake manifold suppliedwith the kit.

91. These next operations are best donewith two people, one on each side of thecar. It makes handling the superchargermuch easier.

NOTE: Lay the supercharger assemblydown into the back of the engine com-partment and allow it to rest on top of thealternator. Illustration 8

92. Slide the new intake manifold on thestuds on the back of the cylinder headand tighten the ten 12-mm nuts to 16 ft-lbs.

93. Prior to bolting the supercharger tothe intake manifold, wrap the supercharg-er drive belt around the super-chargernose behind the drive pulley. This willgive you the most slack in the belt.

94. Center the supercharger gasket sup-plied with kit on the flat lip, square hole,of the supercharger. Lube the bypasshose with WD40 for easier installation.

95. Lift the supercharger into place whileplacing the free end of the bypass hoseover the nipple on the supercharger inletmanifold.

96. Secure the supercharger to the intakemanifold using the four allen bolts sup-plied in the kit. The two bolts nearest theengine block need a small amount of blueLoctite prior to installation. The Loctite willdry quickly so install the bolts expedi-tiously, however, be VERY careful not todrop bolts into manifold runners! Tightenall four bolts to 16 ft-lbs. It is this opera-tion that requires one person to hold thesupercharger in place while the other per-son starts and then tightens all the bolts.

97. Wrap the pipe plugs provided in thekit with teflon tape and screw them intothe top of the intake manifold coveringthe two allen bolts just installed.

98. Looking up from under the car, checkthat all the hoses and wires are routed sothey will not be chaffed by the superchar-ger. Also make sure that everything isclear of the oil filter so that it can be easi-ly removed for oil changes.

99. Wrap the 1/8 NPT x 3/8” barbed pipefitting with Teflon tape. Then screw it intothe bottom of the supercharger/throttlebody inlet manifold. This hose barb is forthe PCV valve hose and, on 96-99 mod-els, the Purge Cut Solenoid Valve “Tee”and hose.

100. Get the PCV valve that came out ofthe oil separator box and get the 18-inchlong, 3/8-inch diameter hose. Connectthem together before installing. Insert thePCV valve into the oil separator box.Route the hose out of the oil separatorbox toward the driver’s side and down theside of the oil separator box.

101. From under the car reinstall the oilseparator box to the back of the engineblock. From the passenger fender,reconnect the original oil separator hoseback onto the engine block fitting.

102. Get the 3/8-inch hose that was rout-ed from the PCV valve along the side ofthe oil separator box. Connect it to theinlet fitting on the bottom of the throttlebody inlet manifold. If you have a 96-01model, you will be installing a 3/8” vacu-um “Tee” in this hose. One end of the“Tee” will supply manifold vacuum to theoil separator. The other end will connectto the “Purge Cut” valve supply fitting.

NOTE: Disregard instructions 101, 102,and 103 if your vehicle is not equippedwith an oil cooler (98-01 USA).

103. Reinstall the oil cooler with onecoolant hose fitting on each side of the oilpressure switch. The two coolant hose

Supercharger Installation Instructions

115. Find the factory IAC hose from thewater supply pipe and connect it to theIAC valve. Reconnect the IAC plug withthe new extension. The wire colors areyellow with a black stripe and black witha blue stripe.

116. Take the 12-inch long by 5/16” diam-eter coolant hose supplied with the kitand connect the hose from the vacant fit-ting on the intake manifold near the #4cylinder. Connect the other end to thefast idle valve mounted on the bottom ofthrottle body. On 98-01 models, disregardthis operation. Instead, install an 1/8”NPT plug above the #4 cylinder. On the98-01 models, reconnect the originalhose from the cylinder head, near the dis-tributor, back onto the bottom of the throt-tle body’s Fast Idle Valve.

117. Reinstall the double metal hoses byreconnecting them to the coolant thermo-stat, the new 4" long valve cover venthose, and the coolant hose coming fromthe fitting on the engine block next tothe top radiator hose. The final open pipewill be connected to the large rubberhose from the air box when it is rein-stalled.

118. If the vehicle has over 15,000 mileson the fuel filter, replace the fuel filternow. A new fuel filter should be availableat your local Acura dealer. Always usegenuine Acura filters when possible.

119. Reinstall the fuel filter and bracket.

120. Reconnect the charcoal canisterhose from the canister to the vacuum fit-ting next to the Manifold AbsolutePressure (MAP) sensor on the throttlebody.

121. Attach the Purge Cut Solenoid Valveto the intake manifold mounting boss, onthe passenger side of manifold, with itsphillips head screw.

122. One of the remaining empty fittingsabove the throttle body should have thevacuum hose for the supercharger by-pass valve hose connected to it, the otherwill have the Purge Valve (94-95) con-nected to it. If you have a 96-99 model,you will need to tee into the PCV hosethat was connected in step 102, to makethe Purge Valve work.

124. Reinstall the throttle cable supportbracket in the middle of the firewall.Reconnect the throttle cable to the throt-tle body and secure the throttle cable inthe support bracket. Check for full throttleoperation and for the throttle to comeback to the idle stop screw.

125. Reconnect the large diameter rubberhose that connects the throttle body tothe air box. Secure the hose with theoriginal clamps.

126. Connect the remaining double metalhose fitting into the large diameter rubberhose.

127. Make sure all the belts are correctly aligned on the ribs and pulleys.

128. Adjust the alternator belt tension byloosening the idler pinch bolt on the loweridler and adjusting with the tensionerscrew. Tighten until 90 -120 lbs. of belttension is available. (Plan on retighteningthe belt after 5-15 minutes). Ninetypounds of tension can be estimated bywhen a foot long stretch of belt has a 3/8”perpendicular deflection.

129. Do not over tighten the belt as it willcreate excess load on the idler bearingsand shorten belt life. If you are not famil-iar with belt tension, or you do not have abelt tension gauge, refer to your factorymanual for proper belt tension sequence.

Complete by tightening the pinch bolt ofthe idler from underneath car.

130. Finalize the supercharger belt ten-sioning by installing the belt under theidler pulley and attached slotted bracket.Tighten the tension of the belt to ONLY35 lbs. of belt tension by tightening the10-mm headed tensioner bolt from theslotted bracket. When the belt tension isproper, tighten the two 12-mm headedadjustment bolts and the 10-mm jam nuton the tensioner bolt. This belt is veryshort and does not need much tension asit has very little area of rubber to stretch.Longer belts stretch more than shorterbelts. Do not over-tighten either belt.

131. Reinstall the power steering and airconditioning belts. Tighten the tension inthe power steering belt with the wing-nutbolt. Tighten the two 12-mm bolts holdingthe power steering pump. Tighten thetension in the air conditioning belt.Tighten the tension in these belts to 90-120 lbs.

132. Install the fuel injectors into the fuel rail.

133. Reinstall the three phenolic spacers,or install the new ones provided in the kit,over the holes for the bolts that hold thefuel rail to the intake manifold. NOTE: Tohelp keep the spacers from falling off theintake manifold holes, put a small amountof grease on one side of the spacer andthen put that side down on the intakemanifold.

134. Reinstall the fuel rail and injectors.

Note: Be VERY careful not to knock any-thing into the fuel injector holes! Tightenthe three 10-mm bolts supplied with thekit securing the fuel rail to the intakemanifold.

135. Install the fuel pressure regulatoradapter on the fuel rail with the “O” ringsupplied and two allen head bolts. Installthe fuel pressure regulator using the twooriginal 6 x 20-mm bolts and original “O”ring. Attach a vacuum line to one of thetwo barb fittings on the back of the intakemanifold.

136. Install the high pressure fuel hosefrom the fuel filter to the fuel rail.

137. Clip the fuel injector plugs back onthe proper injector.

138. To install the Jackson Racing fuelpressure regulator (Fuel ManagementUnit or FMU), pull the small plastic tabout of the firewall next to throttle cablesupport bracket. Then screw a 10-mmheaded bolt supplied through the regula-tor clamp and into the firewall leaving thefittings facing the drivers fender in a hori-zontal position.

139. Connect the CENTER fitting of theregulator to the fuel return line from thebase of the firewall.

140. Connect the OUTER fitting on theregulator to the original factory fuel pres-sure regulator using the fuel hose sup-plied. Clamp the hose with the newclamps provided.

141. Reconnect the wiring harness’ grayplugs in the corner of engine bay nearestdriver’s door. Make sure the harness willnot come into contact with any movingparts. Refer to Illustration 1

142. Attach the vacuum line from theJackson Racing fuel pressure regulator tothe lower vacuum fitting on the back ofthe intake manifold. Reinstall the brakebooster vacuum hose.

143. Reconnect the air temperature sen-sor.

144. Connect the Jackson Racing FuelEnrichment Relay supplied with the kit.Locate the wiring harness and plug thatwas plugged into the T/A (air tempera-ture) sensor. Cut the red wire with theyellow stripe approximately 2 inches fromthe plug. Connect the two new wiring har-ness’ red/yellow wires to the original redwire with yellow stripe that was cut inhalf. Route the remaining wires and relayto the inner fender on the passenger sideof the engine compartment. Use a plasticwire tie to secure the relay to the positivebattery cable where it is secured to awiring bracket mounted on the passengerside inner fenderwell. Route the loosewire, with the female spade connector, tothe pressure switch. Route the remainingyellow/black wire up to the Purge CutSolenoid Valve wire harness. Using a “T-Tap,” connect it to the yellow wire withblack stripe.

145. Refill the engine oil and coolant.

146. Reattach the negative ground to the

negative battery terminal.

147. Enter the alarm and radio codes toactivate each.

148. To ensure proper belt tension, runthe vehicle until it warms up. Recheck thebelt tension and readjust the tension backto the proper level.

149. Check the tension in the belts every10,000 miles.

150. While the engine is warmed up,reset the ignition timing to 10o BTDC for93 octane fuel, 7o BTDC for 92 octanefuel._________________________________

TIPS:

Now that you have added substantialpower to your Honda, here are some tipsfor best performance and long life. Allowthe engine to warm up for at least 3-5miles before you start working the enginehard, longer in extremely cold conditionsas it will take a substantial amount oftime to get the oil warmed completely tooperating temperature. Running anengine without the oil being up to operat-ing temperature is very hard on yourengine. Install a good oil cooler to keepyour oil from getting too hot and frombreaking down prematurely. During our“Back to Back” SCCA EnduranceChampionships, we saw over 300oF of oiltemperature in our race cars with relative-ly close to stock engines. It makes sensethat with the additional power you arenow generating from your supercharger,ordering one of our oil cooler kits will help

maintain long engine life and provideadditional power.

Install one of our “Power Foam” air filtersas a “drop-in” to your stock air box. It willimprove air volume and will keep the airextremely clean. In superchargedengines, the cleaner the air flows in, thebetter power it will make. The one thingyou do not want to do is make the super-charger have to pull hard to get air.

Although the stock Honda exhaust sys-tem is very good, a good header and cat-back system will help relieve any backpressure. The easier the exhaust gets outof the engine, the better the good air willget in. Keep in mind, in a superchargedengine, as the air gets through the enginebetter, the boost will actually go DOWN,but the power will go UP! So, don’t besurprised if you start improving the intakeair and exhaust system and your boostactually starts reading slightly lower thanit did when it was all stock. Conversely, ifyour catalytic converter is starting todeteriorate, you will see higher boostthan normal, but, your engine willperformpoorly.

Keep your cooling system in good shape.Never run more than 50% anti-freezecoolant to water ratio in the engine, ifpossible. Water cools better than coolantbut does not have the high resistance toboiling or ability to resist freezing. So youmust keep SOME antifreeze coolant inthe engine, but try to run as little as pos-sible. If you haven’t replaced your ther-mostat and your car has over 30,000miles on it, order one of our 160oF, low

Supercharger Installation Instructions

989-500 -17- Revised 07/00

temperature thermostat. It will keep theoperating temperature lower allowing bet-ter power and resistance to detonation.

If your car has 70,000 miles or 7 years onit, you might want to think about replacingyour old radiator with a new one fromHonda. We have found that the calciumdeposit (from hard water) that collects onthe internal cooling tubes of old radiatorswill actually insulate the hot coolant fromthe outside air, even though the radiatorstill has good coolant flow. No radiatorrepair shops that we have experiencewith can remove this calcium deposit.More importantly, your stock coolant tem-perature gauge in your car will move tonormal when the coolant temperaturereaches a temperature near 160oF, butyour stock gauge will not show anychange or movement in temperature untilthe engine coolant temperature reachesnearly 220oF. This means that you couldbe trying to operate you superchargedengine in a hostile environment that is60o hotter than is ideal.

Order a set or our colder spark plugs forsummer use. This, like the thermostat,will lower the combustion chamber tem-perature allowing better power and lesschance of detonation in hot climates.

If you are forcing more air into theengine, you want to ensure you haveplenty of fuel. The stock fuel pump worksgreat when new for highway use.However like a radiator, it can grow weakwith age and run out of volume in highdemand, sustained (racing) loads. Ourhigh output fuel pumps are just the ticket.

Our fuel pumps fit in the original in-tankbracket for ease of installation. Thedesign is capable of sustained highdemand without loosing pressure.

Do not run “Upgrade Chips” in yoursupercharged engine. Most “chips” havea more aggressive ignition-timing curve.This is very counter-productive in super-charged engines.

Do not run an after market cam-shaft witha supercharger unless it has been specif-ically designed for supercharging. Mostnon-supercharged high performancecamshafts depend on having both intakeand exhaust valves open at the sametime to help fill the cylinders. This, also, iscounterproductive to superchargers.Anytime that both valves are open theboost goes out the exhaust port and willnever be seen again.The stock ignition system is quite good,as it is the same ignition that is used inall models including the Type R withnearly 200 hp. This is not to say thatsome of the aftermarket systems mightnot work well. It is just an observation.We recommend using the stock systemuntil you encounter a problem igniting themixture. Then try some of the ignitionsthat are commercially available.
