s14 sr20det timing 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. So timing light in one hand, throttle in the other. Snip the others off. It opens/closes the AAC valve to allow more/less air into the engine. Complete RWD/FWD OEM SR20 Timing chain kit, this kit includes everything necessary to change the timing chain and upgrade to S15 components for your B13, B14, B15, P11, S13, S14 and S15 SR20 and VVL motor. Genuine Nissan Timing Chain for SR20 DET engines. You basically just need an air source that has been through the airflow meter into the IACV. For the SR20DE it is 15 degrees BTDC. Anyone who thinks he can drill the caps as well as the factory is either having himself on or is extremely skilled. 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. The plumbing between the AFM and the turbo inlet can be critical. Instead of declaring it broken and throwing it in the bin like workshops all over the world do. That would be great. Similarly for BOV’s that vent to atmosphere. 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. Yop ! The top O-rings are usually fine. More gives extra power but may lead to detonation and subsequent engine damage. This guide assumes that the timing chain is installed correctly. 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. do you happen to have a pic of the end of the cam(s) with the stamping? If you can't open a tin of cat food without cutting yourself then you should probably leave this to somebody else. They become dirty due to normal airborne crud and from oil mist that naturally occurs in the inlet tract. This can be real problem for your SR. Faulty wiring will also do it. It consists of a potentiometer (just like a volume knob) that rotates as the throttle is opened and closed. This is a complete timing chain kit for the S13 SR20DET. This should be 15 degrees and this is when you take your reading. If fuel lines are not securely clamped or leaks exist in equipment then high pressure fuel will spray and often atomise. SR In … This is rare but can happen. Stock cams have two notches so that they can be used on intake or exhaust. This is made to sound like they've carefully matched them to give you a superior quality part. 1 cylinder coil pack and the spark plug, shown below. You'll see the timing mark jumping around at idle and then when you increase revs to 1100 or so it will suddenly stabilise. For S13 SR20DET only. … '69 Datsun 2000 Roadster vintage race car (Street driven on a regular basis :taz. Technical - S14; Simple SR20DET Cam Timing; Results 1 to 6 of 6 Thread: Simple SR20DET Cam Timing. This one is very important. As the name suggests this lets the ECU know how far open the throttle is. The bottom ones sometimes need to be replaced. Hi, I can help. All idle air gets to the engine via the IACV. It's not that hard once you know what values you should be seeing. Then press the injectors into place. Often the pump will start making more noise than usual. Refer to TPS Adjustment section. 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. 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. One line from boost source to wastegate actuator as mentioned above. 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. On the S13 there's also a black GND wire on the white plug - so snip it too. Diagnosis: The next thing to work out is which O-ring is damaged. One line from inlet manifold to BOV. The Nissan SR engine is a 1.6 L (1,596 cc), 1.8 L (1,838 cc) or 2.0 L (1,998 cc) straight-four, four-stroke gasoline internal combustion engine manufactured by Nissan Motors.It has an aluminum head and block with steel sleeves and has a DOHC 4-valve design, with variable valve timing on select models. There are many types around but the one that has caught my eye recently is the Innovate "MTX". but the position of the cam look like same as mine. Choose Options. But they're all made by JECS. tegls1 Posts: 75 Joined: Mon Mar 29, 2004 10:56 am Car: 95 S14 SE, Audi A6 Biturbo. Which can result in damage to the injectors, damage to fingers and general bad language. The spray pattern is usually massively inferior to the factory injector. You will create your very own personal tuning hell. From there we go to 550cc (yellow) and 740cc (red) which are sold by Jap tuning companies HKS, Apexi, Tomei and NISMO. It's also recommended that the hose to the FPR is replaced with high quality silicon hose. 1. I've seen both. Without it you are really in the dark. Removal: SR20 injectors can actually be quite difficult to remove if you don't know the technique. Datascan also has a handy feature under "Active Tests" called "Base Idle Adjust" - this locks timing at 15 degrees. Use a recirculating BOV and have it enter the pipe close to the turbo and angled towards the turbo. Below is an exploded diagram of the engine components in relation to the timing belt. Make sure you get the line that is supplying the fuel rather than the return line to the tank. An eyeglass helps here (about $5 from Jaycar - the one used in the photo is actually a lens from an old scanner!). Here's a little article I put together for SR20 BOV's. This triggers a flag in the ECU which makes it go into idle mode. 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. 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. For the SR20DE, the timing marks are as pictured. They suffer from moisture ingress. Then it's just a matter of wiring it into your loom. Nissan ECU's use IGN timing to trim idle speed. Simple SR20DET Cam Timing I have been struggling with cam timing until I devised … 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. So you sometimes need to go back and forth between the two adjustments to get them both right. Not tape, no soldering. Standouts being the Bosch EV14 series and the closely related ID1000's both of which perform brilliantly. See the throttle stop screw on the throttle body? Acetone is good. This allows you to knock out one cylinder at a time from a laptop connected to the Consult Diagnostic Port. As if the engine isn't really trying. hi just want to confirm if this little dot on stock 248 are the timing marks ? It's usually recommended that they are replaced. The one that gives minimum change is the one that's leaking. Checking fuel pressure is inherently dangerous. Slowly open the throttle - you should see the voltage increase smoothly to just over 4V. Sometimes they will barely idle. 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. It monitors the TPS position and when it's in a certain range (normally 0.35 to 0.65V) it assumes the throttle is closed. At target idle you'll see 15 degrees, if idle is too high you'll see less than 15 and if idle is too low the ECU will try to increase RPM by adding timing. The SR20DET is a fantastic engine from Nissan and is extremely strong and reliable. The TPS in auto vehicles is notoriously unreliable. It gets a bit harder if there's more than one. You need the Green (Tx), Green/white (CLK) and Green/black (Rx) wires. 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. If it starts up and settles into a smooth idle then things are fine. So timing light in one hand, throttle in the other. The top end of the timing chain mating (silver) mark should be at the large idler sprocket gear mark. And most of the time they were right - to start with anyway. Donc petit rappel, le SR20DET c'est le bloc qui se trouve dans les Nissan 200SX S14 et S14A (On le trouve aussi dans les Sunny GTiR et Pulsar). These sockets provide power to the ECU, as well as the signals from the gearbox. (also fits most Infiniti G20 and Sentra models with the SR20 engine) Anything leaner than 12.5:1 should be considered dangerous unless the engine has been specifically tuned for lean mixtures. Engine must be at normal operating temperature. OEM Nissan S13 SR20DET Complete Timing Chain Kit. 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. Either of the fittings under the TB will do. 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. Inspect the two elements under a really good light. If you see any sudden changes (to 0V or 5V) then the TPS must be replaced. The blue box highlights the position of the CAS. The biggest culprit is indubitably fuel pressure. If not, adjust the idle screw on the idle control valve until it does. It's only once boost is applied and the pump is asked to supply higher pressures that they will be found wanting. Take a close look at them - if they haven't bounced back to a nice round section or have cracks/nicks/perishing then don't even bother trying to re-use them as they will leak. Sounds simple but it's amazing how many people mess this up. Random general interest article on oils. 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. If you're setting your idle from scratch then there are a few things you need to know about. (see FPR). Often a lazy fuel pump will be capable of supplying the correct pressure at idle and even atmospheric. Tuned engines usually run around 12:1. Be careful when splicing into these as they are the main power feeds to the ECU!. With engine warm the AAC valve signal should sit around 50%. Below is a picture of the S14/S14a SR20DET engine. Creating an extremely dangerous situation. There is a limited number of side-feed injector manufacturers. Now you can plug in and see exactly what's going on in your SR. For more info on how to communicate via the consult port have a look here. I've not met any injectors molesters in the latter category yet. If a bottom O-ring is leaking then the potential exists for fuel to dribble into the cylinder over time (usually overnight). We've been running Innovate gear for years and they make a decent product. set idle to 750rpm … Unfortunately this is quite common. R32/Z32's can be cleaned but not quite as easily because the sensing elements are not a bolt-in job. This is the company (now owned by Bosch) that makes all the electronic components for most Nissans. Join Date: 19, 1, 2015; Posts: 984; Share Tweet #3. There are also Blitz 850's now, but I'm not sure on fitment or who makes them. Less than 15 degrees will make it very sluggish. thanks dietrich i was thinking the same as a early cam , agree with you the orientation looks correct , so i will use this dot as the marks. Bad for turbo and bad for tuning! [NISSAN] - Préparation du SR20DET (S14) selon HORSHAM Nicolay45 le Mer 20 Fév - 9:42. A sticker like the one pictured may be found somewhere in the engine bay, and the ever important factory ignition timing setting. 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. and solvent such as acetone or contact cleaner. Often you'll get away with it. Injector Upgrades: While we're on the subject of injectors, please don't buy drilled out injectors. 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. Symptoms can be hard to fathom as sometimes they will cause the engine to run lean, other times rich. It will also adjust ignition timing to trim idle higher/lower. Using 2 small screwdrivers and the screws as jacking posts, lever the injector out. I have a 2001 Nissan pulsar (N16) with a QG15 motor and the. You'll see the timing mark jumping around at idle and then when you increase revs to 1100 or so it will suddenly stabilise. It is recommended to replace your timing components when doing an engine rebuild to prolong the life of your motor. 2,608 satisfied customers. Get the nice thick wall hose if you can. Tooth offset - 16. Once you're happy that everything is in order you can monitor the AAC valve signal (using Datascan etc.) Don’t tee anything else off of here. A dirty AFM can also cause your engine to lean out. 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". Diagram of consult signal locations for the common ECU's. Firstly, turn the IGN on and let the fuel pump prime the system. If you're not then your fuel pump will just get "lazy". Quote; Post by pampadori » Mon May 19, 2003 3:21 pm . Firstly there are two different ways to place the pickup. The easiest way is to grab one from a wreck. Use an air filter with a bellmouth entry if possible. In the morning the engine will start on 3 cylinders and it will take awhile before the affected cylinder clears. The purpose of the throttle stop screw is to prevent the throttle butterfly from sticking in the bore. Keep it pre-throttle body as the WG actuator is not designed to operate with vacuum. City & Guilds. One line from inlet manifold to Fuel Pressure Regulator. To avoid these nasties try the following technique: Replacement: Make sure the O-rings are in good condition before replacing the injectors. Some engines use a switch on the TPS to provide this - SR20 ECU's simply look for a certain voltage on the TPS (Throttle Position Sensor). Voilà vu que j'sais pas quoi foutre au boulot, je fais ce petit sujet qui pourrait certainement servir. View Profile View Forum Posts View Rides; Guest Join Date Dec 2004 Location Nr Oxford Posts 543 Rides 0. And keep the plumbing nice and smooth - no sudden changes of diameter or sharp bends etc. Now it's just a matter of getting the signals in the right place. Particularly if you're one of the big horsepower guys running high boost - if a turbo engine leans out under boost your EGT's (Exhaust Gas Temperature) will increase and you'll do engine damage very quickly. This is as simple as tee-ing a gauge into the fuel line where it enters the fuel rail. Now i have locked the timing at 15 DEG btdc, and marked my 15DEG btdc mark on the pulley, with white. Little things that can make a world of difference to your SR. Some of the hoses you'll see will be for the factory charcoal canister. S14 uses 'low port' intake design vs. S13 'high port' design. Join our Rewards Program & save! 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. The upper timing chain mating (gold) mark should be at the small idler sprocket gear mark. Once this happens the ECU sets the "Throttle Closed" flag (this flag can be monitored using any of the diagnostic packages available). To remedy this problem, I turned to the Nissan SR20VE/NEO VVL swap parts specialists … The pins in the connector for S13/early S14 are the same as Z32. 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. Get 'em wrong and smoke will come from your ECU. Best way is to just splice into the ECU power. But if they are firing fuel into a manifold that has been pressurised to (say) 10psi by Mr Garrett then they are facing an uphill battle. It's actually very easy to change your AFM connector to Z32. Some ECU's will learn where TPS Closed is by checking the value at startup. There's one less excuse for blowing your engine up right there! Get superior performance with Nissan aftermarket parts from Enjuku Racing. -chris. Standard idle speed is 825rpm when warm. So far so good. Other people have had trouble using the loop and prefer to sense directly off of No. S14 SR20DET Main Engine Harness for S14 240sx - OEM SERIES. Where this all goes astray is if something happens to that little piece of hose. This is because the engine must be at its correct idle speed for the timing light to be accurate. Although this is not the primary load sensing device, it can upset things pretty badly if it's faulty or not adjusted correctly. -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 They bolt up but you'll need to replace the 6 pin TPS connector and replace it with a 3 pin manual TPS connector. If you've converted to a manual trans then it pays to also convert to a manual TPS for reliability's sake. Far from it. It pays to mark it with some white-out or brightly coloured paint. This is because the Consult Port is part of the body loom - the plug will normally be around the fusebox inside the car. It takes a fair amount of force to get them in. This is not some internet rubbish trawled up from a forum - it happens ALL THE TIME! line from pre-TB to Idle Air Control Valve. Happy days! So what happens is that with 0 psi boost the fuel pressure is 43.5 psi. 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. Only required if your conversion needs to pass emissions regs. Not much to this one - but it's quite important. A good place to start is probably how the ECU controls idle. Thread Tools. This is normal. This page was generated at 11:48 AM. To measure the ignition timing you will need to connect a timing gun to either an HT lead placed between the no. So if you need to adjust idle (you shouldn’t have to) then do it on the IACV – not the TB. Clean element using a fine brush and solvent. 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. PRP R35 GT-R Smart Coil Kit for RWD SR20DET - Bracket, HW, Stalks USD $355.00. Don't use chassis GND. Snip the plug out with about 200mm of wire if possible. 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 return air from the BOV should be angled away from the AFM if possible – reducing the risk of airflow backwards into the AFM. They may not be stock 248s. I set the followig : Triger angle BTDC - 48. 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. Another (preferable) technique is to use the "Power Balance Test" in Datascan. A quick glance occasionally while driving is all it takes to make sure you're still in the safe zone. Supposedly the alternator fails more than many other vehicles, but we are not able to verify this problem. Here's a picture: Top. If this is your first visit, be sure to At 50% the ECU can adjust up/down to trim idle speed as required. There's often black crud evident. Things you can do yourself instead of having to pay somebody else. This is a collection of stuff that we get asked all the time. Don't rev it too much or you'll see timing start to increase. ECU must be seeing "TPS Closed". What is included? Dirty airflow meters are becoming quite common now that most SR's have quite a few k's on them. The problem is if the bottom O-rings haven't sealed properly. The other way is to hold the throttle open very slightly (TPS Closed flag must still be set) to increase revs a bit. If you think about this, it has to - because the injectors are firing their fuel into the manifold. To work out that the engine is trying to idle it monitors the TPS voltage to see if the throttle is closed. Then check carefully for external leaks. Could some one also go through the steps in timing the ignition. Not good. This should be around 0.5V. Don't touch it. These are the black/white wires near the end of the connector. By trying to adjust the idle you will just cover up the symptoms. How do I know if my fuel pump is up to it? The idle is controlled by the AAC valve (Auxiliary Air Control). This CAN cause serious engine damage - I've seen bent conrods. Then bad things happen - combustion temps increase, detonation starts and the next thing you know you've got bits of SR all over the shed and you're pricing engine components. When the auto trans half goes faulty the trans will not shift correctly. Without laptop: Nissan say to disconnect the TPS to lock the timing but I've not had a lot of success using this method. nissan: timing marks..crank and camshafts..on replacing timing chains. Usually there’s a fitting in the factory plumbing that hooks this line in just before the TB. 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.
