These sockets provide power to the ECU, as well as the signals from the gearbox. line from pre-TB to Idle Air Control Valve. $125.00 Add to cart. Timing marks are a little more pronounced on mine, notched and then an indention: Additional photos of the stock markings, from my car a couple weeks ago: why my cam have a little dot instead of pronounced notch ? There is a limited number of side-feed injector manufacturers. 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. Don't rev it too much or you'll see timing start to increase. EFI systems maintain high fuel pressures after the engine is shut down (as you will know if you've ever removed a fuel hose/injector without first bleeding the system pressure). Another (preferable) technique is to use the "Power Balance Test" in Datascan. Often a lazy fuel pump will be capable of supplying the correct pressure at idle and even atmospheric. They work perfectly well. 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. Not much to this one - but it's quite important. Now with the MTX they've made a fully digital gauge with all the control circuitry built-in - all housed in a 52mm round gauge. They suffer from moisture ingress. Nissan have provided a loop in the wiring loom that drives coil No. We've been doing it for years with temperature and oil pressure gauges, so why not keep an eye on our AFR's? Quote; Post by pampadori » Mon May 19, 2003 3:21 pm . Instead of declaring it broken and throwing it in the bin like workshops all over the world do. Konig. So if you need to adjust idle (you shouldn’t have to) then do it on the IACV – not the TB. With engine warm the AAC valve signal should sit around 50%. You really need this part if you are serious about having your SR run right. You will create your very own personal tuning hell. Here's a little article I put together for SR20 BOV's. The SR20DET is a fantastic engine from Nissan and is extremely strong and reliable. Below is a picture of the S14/S14a SR20DET engine. Use what Mr. Nissan gave you. If you have a huge fuel system and the factory FPR cannot bypass enough fuel (ie: fuel pressure is always too high) then make sure you buy a "linear rate" FPR (ie: fuel pressure increases 1 psi for each 1 psi of boost). Where this all goes astray is if something happens to that little piece of hose. If you're setting your idle from scratch then there are a few things you need to know about. The ECU feeds 5V to one, 0V to the other and a voltage somewhere in between is picked off and sent back to the ECU. Don't rev it too much or you'll see timing start to increase. Anything leaner than 12.5:1 should be considered dangerous unless the engine has been specifically tuned for lean mixtures. Then you just watch the reported timing value live on the screen and adjust your Crank Angle Sensor until what you're seeing on the crank pulley (with your timing light) matches what's on the screen. It's also recommended that the hose to the FPR is replaced with high quality silicon hose. If you think about this, it has to - because the injectors are firing their fuel into the manifold. In the case of a non-turbo engine power will be down and if the engine is used continuously at full load it may suffer damage due to detonation and/or valve damage from high combustion temperatures. R32/Z32's can be cleaned but not quite as easily because the sensing elements are not a bolt-in job. Voilà vu que j'sais pas quoi foutre au boulot, je fais ce petit sujet qui pourrait certainement servir. You can monitor this via the Consult port using a laptop. Autos : These use a different TPS. Some ECU's will learn where TPS Closed is by checking the value at startup. A wideband AFR (Air Fuel Ratio) meter is one of the main tools used when tuning turbo engines. 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. This should be around 0.5V. So as boost rises, so does fuel pressure. 2,608 satisfied customers. Most Nissans from around 1990 to 2000 had them. From there we go to 550cc (yellow) and 740cc (red) which are sold by Jap tuning companies HKS, Apexi, Tomei and NISMO. At 50% the ECU can adjust up/down to trim idle speed as required. This is a complete timing chain kit for the S13 SR20DET. If you pull too hard on the wires without pushing the little tang in from the other side you will wreck the backshell and the pin. S13 200sx SR20DET + Gearbox Fitting Guide SR20DET & Gearbox Fitting Guide for LHD European S13 200sx John Bennett Additional research: Marty_T3 and Fry1 This document considers There are 3 plugs (F8, F9 and F10) that go to sockets by the fuse box. Sometimes idle will only be slightly affected and the car will drive fine otherwise. This page was generated at 11:48 AM. Below is the intake and exhaust camshaft pulley marks. How To Set CAS Timing on the SR20DET Resetting your engine's timing back to factory setting is pretty straightforward thanks to the markings provided on the CAS, cams, and pulleys. Top. Here's a picture: Top. Don't worry too much about that. This is a flag which is set inside the ECU when the throttle is closed. Little things that can make a world of difference to your SR. If your throttle is closed but the ECU doesn't see it, then stable idle will be impossible to achieve. Then press the injectors into place. It has 6 wires. Registered User. Now it's just a matter of getting the signals in the right place. Use an air filter with a bellmouth entry if possible. So even though the flow rate matches the other injectors, the spray pattern is horrible and so low load/cold start/idle/emissions and fuel economy figures tend to be severely compromised. Make your engine happy (and quieter) with a new timing chain kit. Then tighten the lock nut. Adjustment is not as obvious as it might seem - particularly if you're used to old school carby engines. Diagram of consult signal locations for the common ECU's. Remove the injector plugs one by one as the engine is idling. Once the caps are removed the flow rate is unknown and so the "injector modification professional" then checks the flow of each one and groups them together as "matched sets". Then fuel pressure will be low and your SR will lean out. Best way is to just splice into the ECU power. Only required if your conversion needs to pass emissions regs. We've been running Innovate gear for years and they make a decent product. If this is not happening then it uses the main timing maps to determine IGN timing - this will not give us the 15 degrees we're looking for. Now i have locked the timing at 15 DEG btdc, and marked my 15DEG btdc mark on the pulley, with white. 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. Enjoy. Drawn looking at wires side of ECU connector. They should look like a shiny glass bead with a fine wire wrapped around it. Worst case the cylinder will have enough fuel in it to hydraulic lock. Check all your hoses around the inlet area first. Firstly, turn the IGN on and let the fuel pump prime the system. In the morning the engine will start on 3 cylinders and it will take awhile before the affected cylinder clears. This should be 15 degrees and this is when you take your reading. If the AFM is too close to the turbo and/or the plumbing is sloppy you may experience poor return to idle and general grumpiness at idle and low load. You'll need a Consult Cable, a laptop and some monitoring software. I've not met any injectors molesters in the latter category yet. Join Date: 19, 1, 2015; Posts: 984; Share Tweet #3. Downside : the pins can be a bugger to remove if you don't know what you're doing. And most of the time they were right - to start with anyway. This is a step by step to set timing on sr20det also if you have any question let me kno ECU must be seeing "TPS Closed". I've got an old crusty timing light and this loop works fine with it. Now you just need a power wire. '69 Datsun 2000 Roadster vintage race car (Street driven on a regular basis :taz. Nissan Home window - 16. If this is your first visit, be sure to They're invariably rubbish. 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). The other half has switches (for throttle fully closed and fully open) which go to the auto trans to determine shift points. Although this is not the primary load sensing device, it can upset things pretty badly if it's faulty or not adjusted correctly. Details vary between models but the basic concepts are the same. If you tee into the hose going to the FPR and a leak develops somewhere in your boost gauge/EBC then the FPR won't get the correct boost signal. Gracias:ylsuper . Happy days! Random general interest article on oils. They all drop in perfectly, the connectors fit and they have 4 precision machine holes in the cap that result in a reliable precision spray pattern. One line from inlet manifold to Fuel Pressure Regulator. If there is any doubt on the installation of the timing chain, do not proceed as damage to your pistons/valves can occur. This is because the Consult Port is part of the body loom - the plug will normally be around the fusebox inside the car. Choose Options. All images and content are © Copyright s14.net 2012. The picture below is the crankshaft marks that need to be lined up before you remove the timing belt. This plug normally plugs into the body loom and contains signals that go from the ECU to the dash. Then check carefully for external leaks. So far so good. Tuned engines usually run around 12:1. The upper timing chain mating (gold) mark should be at the small idler sprocket gear mark. Until recently they were considered a specialist tool and had a pricetag to match. check out the. It opens/closes the AAC valve to allow more/less air into the engine. So what happens is that with 0 psi boost the fuel pressure is 43.5 psi. Consult signals can be found on the main ECU connector near the bolt in the middle (see below for diagrams). Your tuner probably tuned your engine with an AFR between 11.5 and 12:1 if it's a turbo, or a tad leaner if it's NA. iI didn't read all the posts,but it seems you have the exhaust on the intake and vice versa.Looking at the picture you an see the correct square notch further down to the side of the cam.Imagine putting that came on the other side with the lobe pointing the way it points now.at TDC , firing for number one,and should line up with the notch.As for the little point it appears that it was made with a centre punch by somebody,Cheers, Or you have the TDC firing for cylinder number four.Remember both pistons are at TDC at the same time.One cycle fires for number one and another for number four, i think they are not stock 248 , they doesn't say bmw , neither 248 , i purchase a complete head and the guy told it came from a racing engine, just check the flange of cam and it have an E stamped. Standard idle speed is 825rpm when warm. nissan: timing marks..crank and camshafts..on replacing timing chains. 1988 M3 2007 Lotus Exige S. Comment. (also fits most Infiniti G20 and Sentra models with the SR20 engine) Nissan ECU's use IGN timing to trim idle speed. If you've snipped a plug from a wreck then you may have different coloured wires. This isn't usually too hard to work out. It's usually recommended that they are replaced. warm engine. I am using the Base map that Scott sent me, and iam trying to set the trigger etc. This one is very important. Air gets stopped by the suddenly closed throttle and then surges backwards through the compressor and out the AFM. The other two chain mating marks should at their cam gear marks. what is the position of the timing marks on setting up the crank and camshafts on a ka24 2.416v nissan 1 tonner on replacing timing chains … read more. Clean element using a fine brush and solvent. -S14 SR20DET into DOHC S13 swap-RB20DET Into S-Chassis Wiring-Choosing the Right Motor Oil-Fix Your Timing Chain Rattle-Replace Timing Chain-Replace Timing Chain (KA24E)-SOHC KA24E Timing Chain Replacement-Adjusting Distributor (Timing)-Adjust Timing-Greddy Rocker Arm Stoppers on a SR20DET-KA24DE Oil Pump Inspection The Consult Port is extra handy for doing this check as you can log the TPS value while you drive the car - and then check the trace for any drop-outs later. So you sometimes need to go back and forth between the two adjustments to get them both right. The top O-rings are usually fine. Often you'll get away with it. So the idle problem is more than likely due to a fault with the installation. Any air leak into the manifold will increase idle speed. This makes them cheaper to produce ($US199 last time I checked - 16May11). An eyeglass helps here (about $5 from Jaycar - the one used in the photo is actually a lens from an old scanner!). Another prevalent issue is a rattling timing chain, which occurs when the timing chain gets loose from age and begins to rub against the timing chain cover. One line from inlet manifold to BOV. Bad for turbo and bad for tuning! They are not hard to fit either. Fuel pressure can decrease for many reasons but the most common are worn fuel pumps and blocked fuel filters. One big (15mm?) 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. The plumbing between the AFM and the turbo inlet can be critical. Use good quality silicon hose and even put clamps on each end. And keep the plumbing nice and smooth - no sudden changes of diameter or sharp bends etc. They bolt up but you'll need to replace the 6 pin TPS connector and replace it with a 3 pin manual TPS connector. Engine must be at normal operating temperature. Get the nice thick wall hose if you can. Put it all back together, congratulate yourself on a job well done and shout yourself a beverage for being smart enough to clean your AFM. The blue box highlights the position of the CAS. Simple SR20DET Cam Timing I have been struggling with cam timing until I devised … Rotate them back and forth as you push. Dirty airflow meters are becoming quite common now that most SR's have quite a few k's on them. There's often black crud evident. The return air from the BOV should be angled away from the AFM if possible – reducing the risk of airflow backwards into the AFM. tegls1 Posts: 75 Joined: Mon Mar 29, 2004 10:56 am Car: 95 S14 SE, Audi A6 Biturbo. A sticker like the one pictured may be found somewhere in the engine bay, and the ever important factory ignition timing setting. (see FPR). 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!) Adjustment : This can either be done manually (with a multimeter) or by plugging into the Consult Port with a laptop and reading it straight off the screen. Once you're happy that everything is in order you can monitor the AAC valve signal (using Datascan etc.) So timing light in one hand, throttle in the other. 1. 1 plug by making a plug lead extension. See the throttle stop screw on the throttle body? The bottom ones sometimes need to be replaced. There's one less excuse for blowing your engine up right there! S14 SR20DET Zenki to … but the position of the cam look like same as mine. It will also adjust ignition timing to trim idle higher/lower. They come in a limited number of flow rates. It is recommended to replace your timing components when doing an engine rebuild to prolong the life of your motor. Most are made by JECS. Similarly for BOV’s that vent to atmosphere. On these engines the TB is totally closed at idle. Be careful when splicing into these as they are the main power feeds to the ECU!. If not, adjust the idle screw on the idle control valve until it does. It should take a couple seconds before pressure goes to zero and the engine dies. So when it is cranked it simply locks solid. Nissan Silvia S14 200SX S14A SR20DE SR20DET JDM. What is included? Under load a standard SR will run very rich - often richer than 10:1. Not good. City & Guilds. Not good. S14a/S15 use different pins, so you'll need to snip off the old plug and either crimp new Z32 pins on - or get a Z32 connector with a length of wire on it and join the wires. Quick view. That would be great. Creating an extremely dangerous situation. Faulty wiring will also do it. Symptoms can be hard to fathom as sometimes they will cause the engine to run lean, other times rich. do you happen to have a pic of the end of the cam(s) with the stamping? Removal: SR20 injectors can actually be quite difficult to remove if you don't know the technique. There are many types around but the one that has caught my eye recently is the Innovate "MTX". Why your fuel pump is critical: It's easy to think that if your fuel pump is faulty then the engine will just run out of fuel and stop. This is a critical adjustment - particularly if your engine has been tuned for more boost etc. Beyond that you need to go to a tail-feed setup. Use a small jeweller's screwdriver to depress the little locking tangs - and be patient. 1 cylinder coil pack and the spark plug, shown below. The top end of the timing chain mating (silver) mark should be at the large idler sprocket gear mark. It's mounted on the inlet manifold and you will find an adjustment when you peer down between the runners of the manifold on the S13 - slightly different on S14/15 but easy enough to find. OEM Nissan S13 SR20DET Complete Timing Chain Kit. By trying to adjust the idle you will just cover up the symptoms. Bill. I set the followig : Triger angle BTDC - 48. The pins in the connector for S13/early S14 are the same as Z32. It consists of a potentiometer (just like a volume knob) that rotates as the throttle is opened and closed. What you need to know is that the FPR regulates the fuel pressure based on manifold pressure. *S15* S15 Silvia 99+ Horsepower: 250ps at 6000rpm Transmission: 6 Speed, Close Ratio Injector size: 480cc/min Turbo specs: Compressor: T-28, 60 trim 60 mm BCI-1 compressor in T-04B housing Turbine: Inco turbine wheel. With throttle closed you should be seeing 0.5V. Due to mixing and matching the VVL FWD and SR20DET RWD conversion parts, the timing marks will not align correctly with the VVL oil pump when using the RWD crank pulley. Timing marks are a little more pronounced on mine, notched and then an indention: cam lobe position at TDC by chris tsay, on Flickr Your lobes look to be pointing in roughly the right direction for TDC however, in my picture the engine is rotated to TDC. On some engines the canister is over the LHS and so you have a bunch of lines that run across the top of the rad from the RHS of the engine. Without laptop: Nissan say to disconnect the TPS to lock the timing but I've not had a lot of success using this method. If this happens then the pump will still operate but fuel pressure will be low - resulting in lean mixtures (usually at full load). If idle speed is too low the ECU will add timing, if it's too high then it will pull timing back. On the S13 there's also a black GND wire on the white plug - so snip it too. They run from here to a small white plug about 150mm away on S13 or 300mm away on S14/15. Get superior performance with Nissan aftermarket parts from Enjuku Racing. Could some one also go through the steps in timing the ignition. If it starts up and settles into a smooth idle then things are fine. The easiest way is to grab one from a wreck. A good place to start is probably how the ECU controls idle. 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. But nobody uses them anymore (ahem...). Anyone who thinks he can drill the caps as well as the factory is either having himself on or is extremely skilled. When using the VVL front cover, the timing pin is shorter, so it places the marks on the opposite side of the RWD pulley. Before you do consider this : unless the engine is a real clunker then there's a pretty good chance that the idle was spot on before it was removed. So at 10 psi boost the fuel pressure should be 53.5 psi. My Evo2 cam has a notch for the timing mark. It gets a bit harder if there's more than one. Note also that the timing marks start at -5 degrees so 15 is the 5th mark from the left. The system is set up so that the injectors deliver their fuel at 3 bar (43.5psi). Testing: Once you've got them all in place, fit the caps and it's time for testing. Or almost any contact cleaner will do. If fuel lines are not securely clamped or leaks exist in equipment then high pressure fuel will spray and often atomise. It's only once boost is applied and the pump is asked to supply higher pressures that they will be found wanting. Snip the plug out with about 200mm of wire if possible. pampadori Posts: 431 Joined: Sun Aug 18, 2002 3:52 pm. This triggers a flag in the ECU which makes it go into idle mode. I'll add pics (and more information) as time permits. set idle to 750rpm … SR20DET Ignition timing. Where do I set the ignition timing on my engine. The spec is 0.35V to 0.65V but it's good to have it right in the middle. Use a recirculating BOV and have it enter the pipe close to the turbo and angled towards the turbo. P2M Nissan Sr20det CAS Cover - Clear … Seems the basic timing lights work best with the loop - the "dial-back" lights need to take signal direct from the plug as they are more sensitive and can false trigger on the wrong edge of the signal. Unfortunately the main TPS part also goes bad very quickly. For S13/early S14 all you need to do is : Result : perfect job that looks like factory. For each psi of boost, the fuel pressure increases by 1 psi - keeping the pressure difference across the injectors constant - this is called a "linear rate" FPR. How do I know if my fuel pump is up to it? Diagram showing normal BOV operation when throttle closes, The stock BOV on most Nissans can actually be made to work very well and hold increased boost with a small modification. It pays to mark it with some white-out or brightly coloured paint. Bleed fuel pressure from the system by removing the fuel pump fuse, relay or wiring to fuel pump with the engine running. It has 3 pins. A quick glance occasionally while driving is all it takes to make sure you're still in the safe zone. As the name suggests this lets the ECU know how far open the throttle is. Here's what you should see: To do the "Atmospheric" measurement you just pull the sense hose off of the Fuel Pressure Regulator (FPR). This is normal. This signal is used to calculate throttle opening speed, throttle position and to sense when the throttle is closed so the ECU can provide a smooth idle.
