Well, I figure I'll probably be asking some tech questions and such about other engine builds over the next few months as I'm getting ready for a new project so I decided to post up my install guide for when I boosted my 2002 RSX-S. Hope this is helpful to anyone who is installing their own turbo... Comprehensive Greddy Turbo install guide. First, remove the front strut bar Now remove the intake manifold cover And release the fuel pressure by first removing the gas cap and then loosening the fuel pressure release valve on the fuel rail Next I removed my DC shorty header and the heat shield. These are the bolts that need to be removed in order to get the header loose from the cat. I couldnâ€™t get good pics of the heatshield bolts so use your imagination Now remove the header Now that you have room to roam, itâ€™s heatwrapping time. This is probably the most frustrating and annoying part. Take my advice and donâ€™t cut any of your zip ties until you are all done with the install. This will help to avoid cutting the crap out of your hands on the sharp edges. Wrap everything in sight. Donâ€™t kill anyone. Take off the wires plugging into the VTC solenoid Now remove the VTC solenoid and its heat shield and pull back the rubber cover on the oil pressure sensor Reinstall the taps and the elbow for the oil pressure sensor and the oil pressure gauge and the oil feed line. Then reinstall the oil pressure sensor, and install the oil feed line and the oil pressure gauge fitting. You may notice that this all doesnâ€™t fit very wellâ€¦ and itâ€™s also recommended to only have 1 t-fitting on the block since all that weight can cause it to break off, and we donâ€™t want that. I decided to get some high-pressure hose with premade fittings and extend it. Sorry, these are bad picsâ€¦ Iâ€™ll try to take better ones later. Next, install the stud bolts in the engine block and on the header, then install the header using your OEM gasket. Heatwrap the turbo actuator, check all fittings and install your turbo and compressor, make sure you remember the gasket. Notice that the oil feed line comes up from the back in this pic. Do this if you are routing your oil feed line from the engine block, otherwise Iâ€™d recommend putting it on later. Fasten the oil feed line to avoid getting any dust or debris in the turbo, if you need to move it later itâ€™s easy. Heatwrap your oil feed return line and install it with the provided gasket. I used an 8â€ extension to do this, youâ€™ll definitely need a long one, at least a 6â€. Install the banjo bolt or the bung if you tapped your pan. Then hook up the oil return bracket to keep the hose from hitting the axle. Modify the driveshaft heat shield if you plan on re-installing it. Now you need to install the downpipe. I installed an EGT gauge so I drilled the DP and then had the bung welded to it. Make sure to run a tap through the bung after to make sure it didnâ€™t warp from the heat. Now install the three stud bolts, gasket and then the downpipe. If you put the EGT sensor in the same spot I did, this can be installed after. Okâ€¦ more removal of stock parts. I donâ€™t have shots of taking off the bumper or removing the front bumper support, so youâ€™re on your own. After that, itâ€™s time to take off the washer bottle. Remove the bolts holding it to the frame and drain that bish. Those things just pop right out of there with a little force applied with a screwdriver. Make sure you have something in place to drain it into. Thereâ€™s a piece of the frame that needs to be removed. Before: After: The horns also need to be removed. Then re-install the horns with the FMIC mounts and spacers in place Next install the FMIC itself, taking care to align it properly Itâ€™s a tight squeezeâ€¦ but itâ€™s not that bad (just wait, it gets worse) but it will fit, I promise. Install the compression pipe on the compressor and then the next one after that. Donâ€™t worry about fastening anything down to the engine block yet, itâ€™s easier to do it later. I had to remove the stock battery grounding in order to properly route the hose. You can see in this pic that itâ€™s in the way. Now install the next piece of the compressor pipe, itâ€™s easiest if you keep the screw heads pointed towards a place you can easily access them for tightening. Test fit and install the compressor pipe to the intercooler Now the real fun begins. Install the large pipe that runs across the front of the Intercooler. Rotate the clamp on the radiator hose so it moves it up slightly as per the Greddy install instructions and cram the charge pipe in there. Itâ€™s a helluva tight fit, but it will go if you have moved the radiator hose enough. Make sure the connections are tightened down very well, as you donâ€™t want to try and tighten those hose clamps after itâ€™s installed. Then remove the battery and the tray; trust me, it makes everything so much easier that itâ€™s well worth the effort. You will also have to remove the clips holding the wires coming from the positive battery cable and bend that bracket out of the way. Next gently feed the final compressor pipe through the maze of wires, tubes and pipes. Take your time and check from the top and bottom to ensure you have it aligned properly. Tighten the clamps down tight and ensure that all pipes are properly and fully inserted into the hose connectors. Remember, if these arenâ€™t tightened properly you wonâ€™t get any boost. Finally, once everything is tightened down properly bolt the piping down to the appropriate brackets. Spacers may be needed as the fitament varies depending on the car. The next step is installing the suction pipe. Assemble the air filter and attach it to the suction pipe. Install the grommet for the IAT sensor. Feed the suction pipe through the forest of crap and fit it on to the compressor. Donâ€™t tighten it down yet though, youâ€™ll need it to be loose for the next step. Now you need to fasten the intake to the bracket to keep it stable. Hereâ€™s a shot of the place on the tranny where it bolts down and of the bracket installed. You might as well install the bracket for the washer bottle at the same time (3rd pic). You can see the other washer bottle bracket in that pic too, but hereâ€™s a closeup just for kicks.
