Important, Read This Before Installation
• The following information and recommendations are presented here for a reason. At Pettit Racing we learned over the years
that keeping a performance car both fast and reliable requires that the driver has a little more knowledge of the systems and is
able to perform a thorough visual inspection. This is very basic knowledge but it can enable you to stop a small detail from
turning into a major repair. And as we all know, this can happen with any car so this knowledge will be of benefit for life.
Observing the following guidelines will greatly improve your chances to drive a top-performing RX8 and enable you to keep it
performing for many years.
• First, always keep up with routine maintenance schedules. This way when you begin adding modifications, it will be to a vehicle
that is 100%. (i.e. fresh, clean fluids and filters, everything working properly, brakes and suspension operational, etc).
Obviously, if your vehicle is not running properly, upgrading could cause more harm. From our experience, we have found that
most problems are caused by simple oversights like a loose hose clamp or mixed-up plug wires. Poor fuel quality also
contributes; it can cause detonation that can damage the engine. Make sure to always run premium fuel. For racing and high
boost, race fuel can be mixed in as well.
• If you are sure your car is 100% you are ready to upgrade. If you are not sure, it is cheap insurance to have a full maintenance
service performed.
• Always add fuel lubricant to every tank of fuel. We recommend at least 4oz of Protek R with every fill up. Protek-R cuts friction,
gains power and reduces wear. Regular use of Protek-R can extend engine life by 30% or more. For more information see our
website: http://www.pettitracing.com/faq/faq_protek-r.htm
• Never allow a rotary engine to overheat; it can be ruined in less than five minutes with insufficient coolant.
• Detonation is bad, if detonation occurs, avoid that operating range until better fuel is obtained or the problem is corrected.
Detonation occurs most commonly at high load/boost levels; avoid driving or drive with light throttle at minimum power until the
problem is corrected.

• Bad ignition coils can cause detonation also and these coils are commonly failing (even without boost), so it’s a good idea to
change them, especially ones with 25,000 miles or more. You can check the epoxy fill on the bottom; usually there are burn
spots or surface flaws if they ever got overheated. It is best practice to replace them and start fresh – now with our coil mount
cooling modification providing more air flow, they should last longer.
• Allowing the engine to properly warm up will greatly extend engine life. This is best accomplished by driving SLOW UNDER
4000RPM and accelerating lightly, for at least 10 minutes.
• Oil and filter change every 3000 miles or less. For hard driving like our test cars, we change every 2500 miles or sooner if it
looks dirty. Make sure you use a high quality performance oil.
• Change the spark plugs unless they have less than 10,000 miles, even then they should be inspected and gapped to .028 .030. Proper torque is essential, we have seen several cases of improperly torqued spark plugs, which can get carbon on the
threads and be very difficult to remove. Carbon on the threads and/or plugs that are loose reduce plug-to-block heat transfer,
run hotter and fail sooner. Improper torque is evidenced by a partially crushed washer.
• After 500 miles or so the compressor oil must be changed (use 20w 50 oil) and the belts and bolts should be checked and if
necessary retightened.
• Be careful when topping up oil in the new oil fill to avoid overfill and spillage running into the oil vent pipes.
• The whole concept behind upgrading is to have fun and to enjoy this one-of-a-kind vehicle. When you rush things, or do too
much at one time, it is much more likely to create problems. Take some time and do the research, learn the basics – it will pay
off in the long run.

Step #2 – Part Modifications (see pages 12 - 16)
Cut the bracket bridge between bolt holes on top of engine, allows clearance for rear stud mount bracket. (Use Snips) (see
page 29)
Cut off left bracket of anti-lock brake manifold (Use Sawzall, Careful not to cut A/C line). Remove enough to avoid rubbing.
Cut away vacuum switch tank from oil fill neck (Use Sawzall or Hacksaw).
Modify air box, Coil mount bracket and mount coils (Use Sawzall, Snips and Drill).
Cut opening in front cowling for heat exchanger hose clearance (Use Snips).
Modification
Heat Exchanger Plumbing
Step #3 – Heat Exchanger Installation (page 18)
Assemble heat exchangers (see page 16).
Connect upper brackets through existing holes in frame using supplied M8 bolts and nuts.
Connect lower brackets to lower radiator mounts, use existing hardware. (Upper brackets will bend slightly to allow the
lower brackets to mount properly).
Re-assemble the following parts: front nose clip, under cover, front/ side running lights (left & right), front wheel well splash
shields (left & right) and front wheels.
Installation
Step #5 - Wiring Harness Modifications (see pages 22 - 31)
Follow instructions to open harness and pull coil and throttle body wires into a split loom.
Connect the ground eye and coil harness connectors.
Apply 6” spiral wrap to main harness.
Install rear stud mount to block, rear bolt gets ground wire (see page 29).
Tie wrap harness back for stud clearance and to prevent harness from being pinched when compressor assembly is set in
place.
Wiring
Step #4 – Hose Re-routing (see pages 19 & 20)
Use 5/16 barbed hose coupling (supplied) to re-connect throttle body coolant hose. Hoses require trimming, see page 18 for
coupling placement. Use 2 existing hose clamps removed from throttle body.
Use 90° elbow from air cleaner / throttle body connector hose to connect the Oil Metering hose to the Jet Air Bypass hose.
Trimming of hoses required, see page 19 for elbow placement. Zip tie or clamp to secure.

mount over the stud. Start and snug the 4 nuts. Slide hump hose onto I/C outlet.
Hold compressor to best position, install and tighten the two 3.5” T bolt clamps.
Tighten 3 front nuts, then rear stud nut, torque these nuts 13-19 lb-ft (1.9-2.6 kgf-m). These should be re-torqued after a
couple hundred miles.
Connect vacuum hoses to manifold nipple and bypass valve. If using a map sensor, connect another 3/16” hose T.
Reinstall alternator and connect wires.
Install belts and set proper tension.
Install modified air cleaner insulator.
Run harness and connect all grounds, main battery, coil ground, ignition capacitor and I/C pump harness.
Mount pump and tank, tie wrap harness along with coil and throttle body harness and secure harness to air cleaner insulator
bracket with zip ties through the drilled holes, keeping plenty of room from moving parts (see page 38).
Connect hoses to I/C inlet and pump outlet, connect return hose to tank.
Install coils and connect plug wires.
Install throttle body, filter adaptor and air filter, connect remaining hoses.
Install 1/8npt to 3/8 hose for brake booster, cut hose to fit and connect.
Fill compressor oil, (20w50 approximately 5 oz. This must be changed after 500 mile break-in).
Fill I/C tank and have a gallon of water ready to refill as level drops
Connect battery switch ignition on and verify pump operation by observing return flow into tank.
Start engine, confirm belts are running smooth in the grooves. Stop engine and verify belt tension is correct.

Reflash procedure with EFIDude dongle
Reflash Procedure:
•Make sure EFIDude dongle is charge with a VIN token and is in programmer mode with the flash programme loaded
•Make sure vehicle battery is fully charged , or has a trickle charger still attached
•Turn the ignition key to position 2 (ignition on, but not engine started)
•Plug in the EFIDude dongle
•The Dude LED should turn RED and stay RED for about 1 or 2 minutes.
•Once the programming starts you will notice all the temperature gauges on the dash drop to zero (showing it has lost
communications with the ECU)
•DO NOT UNPLUG UNTIL YOU SEE THE RED LED TURN GREEN.
•Once the LED turns GREEN you will see the gauges return to normal.
•Unplug programmer and cycle the key to off.
•Turn ignition on
•If the Check Engine Light flashes when first turning the key on, you must reset the cam sensor. Rapidly press brake pedal 25
or so times just after turning the key on, until you see the gauges drop and return to normal. This indicates a successful reset.
•Start the car and let it find idle.
•Turn the dongle back into a logger again so no accidental “reflashes” are done!
•Drive car and log data!
