On cars with auto trans this can easily stall the engine completely. This plug normally plugs into the body loom and contains signals that go from the ECU to the dash. Things you can do yourself instead of having to pay somebody else. For S13/early S14 all you need to do is : Result : perfect job that looks like factory. You'll need nice sharp multimeter probes to pierce the insulation on the wires - it often pays to give them a quick sharpen with a file/grinder etc. We've been running Innovate gear for years and they make a decent product. Don't use chassis GND. Fuel pressures in EFI systems regularly reach 40psi+. Other people have had trouble using the loop and prefer to sense directly off of No. Join Date: 19, 1, 2015; Posts: 984; Share Tweet #3. If you've converted to a manual trans then it pays to also convert to a manual TPS for reliability's sake. You can buy lube specially for this job but if you don't have it then use either Vaseline or engine oil. They become dirty due to normal airborne crud and from oil mist that naturally occurs in the inlet tract. You need 5 wires - 12V, GND, CLK, Receive and Transmit (no CLK on S15). The AFM measures airflow the same in either direction so this surge of air creates a burst of fuel at the injectors, resulting in a big rich cough each time the throttle is closed. Bill. There are some others such as Sard which work OK but are not really made to fit an SR20 - they're made to fit by using a conglomeration of oversized O-rings and adaptor rings. Make your engine happy (and quieter) with a new timing chain kit. You'll need a Consult Cable, a laptop and some monitoring software. -chris. Variable valve timing system and a different turbo are the significant changes from the S13 SR20DET engines. Or almost any contact cleaner will do. Use a recirculating BOV and have it enter the pipe close to the turbo and angled towards the turbo. Adjustment is not normally required but may be performed by backing off the stop screw until you feel the butterfly start to stick in the bore, then screw the stop screw inwards until the butterfly is totally closed but isn't sticking in the bore. The other two chain mating marks should at their cam gear marks. Now it's just a matter of getting the signals in the right place. I set the followig : Triger angle BTDC - 48. remove all the pins from the Z32 connector and slip the rubber boot off, slip the rubber boot from the Z32 connector onto the SR wires, click the 3 pins on the SR loom into the right positions in the Z32 connector backshell, re-fit the rubber boot to the connector backshell. After a few starts (with throttle closed) the ECU will assume that the voltage it's seeing is TPS Closed and the TPS Closed flag will be set. Remove the injector plugs one by one as the engine is idling. You really need this part if you are serious about having your SR run right. Once you get a reliable reading, set the CAS (Crank Angle Sensor) to 15 degrees. The one that gives minimum change is the one that's leaking.

Symptoms can be hard to fathom as sometimes they will cause the engine to run lean, other times rich. Do not under any circumstances fit a "rising rate" FPR (ie: fuel pressure increases more than 1 psi for each 1 psi of boost). Downside : the pins can be a bugger to remove if you don't know what you're doing. So it makes sense to monitor your AFR's. The SR20DET is a fantastic engine from Nissan and is extremely strong and reliable. By trying to adjust the idle you will just cover up the symptoms. And keep the plumbing nice and smooth - no sudden changes of diameter or sharp bends etc. This is a particularly well written article because it's written at a level that anyone can understand rather than going into full-on technobabble. The pins in the connector for S13/early S14 are the same as Z32. Without laptop: Nissan say to disconnect the TPS to lock the timing but I've not had a lot of success using this method. Bad for turbo and bad for tuning! This triggers a flag in the ECU which makes it go into idle mode. What is included? SR20DET Ignition timing. Similarly for BOV’s that vent to atmosphere. Quantity: Tags: p2m phase2motortrend s13 s14 sr20de. Half of it still functions the same as the manual 3 pin TPS - so all of the above still applies (wire colours are different but you still need to measure between the Black and White wires). Once you have a set of good O-rings then you need to go mad with the lube. To work out that the engine is trying to idle it monitors the TPS voltage to see if the throttle is closed. R32/Z32's can be cleaned but not quite as easily because the sensing elements are not a bolt-in job. Fortunately the sensing elements in SR AFM's are easily removable and quite easy to clean. Dirty airflow meters are becoming quite common now that most SR's have quite a few k's on them. Join our Rewards Program & save! If this is your first visit, be sure to It's not that hard once you know what values you should be seeing. Turbo engines are a different story. Make sure you get the line that is supplying the fuel rather than the return line to the tank. Simple SR20DET Cam Timing I have been struggling with cam timing until I devised … This will either need to be done on a dyno or else you can temporarily secure a pressure gauge to the car (keep it OUTSIDE the cabin!)

It's only once boost is applied and the pump is asked to supply higher pressures that they will be found wanting. It's actually very easy to change your AFM connector to Z32. But they're all made by JECS. Snip the wires near the white plug. Beyond that you need to go to a tail-feed setup. Pressure with boost applied is calculated by starting at 43psi for 0psi (=atmospheric) and then pressure should rise by 1psi for each psi of boost. The top end of the timing chain mating (silver) mark should be at the large idler sprocket gear mark. Quick view. If using a multimeter it must be done with IGN ON (engine does not need to be running) and the connector fitted to the TPS.
