Best thing to do is go to junkyard and find a motor similar size as yours and get the complete system and parts. As you read through there will be links to more detailed information including all the wiring diagrams needed to make your own harness or rework one from a donor vehicle. For this one we are doing a ECM, you can get all the wiring diagrams and files for it here: www. TBI system components: 1. Has a number like is used here.

Inside is the chip. On the chip is the bin file which is the program for running that engine. We will have another page for programming equipment, software and accessories needed for changing bin files on chips and another on Tuning!

Coming soon! The injectors are different sizes. The is larger with close to 2 inch bores. It is recommended a TBI from about the same size engine to be used in your conversion or larger for high performance built engines.

TBI Wiring Harness. Wire harness can be pulled from the factory car and reworked for a conversion.

There are also aftermarket options to buy one new already made. Here's an idea of what one looks like when pulled. Here's the harness you need and the pile of stuff removed. More Detailed wiring information at this link: www. You could pull from donor but a new one is cheap. The universals just splice onto the wire from the harness. For headers It is recommend a 3 wire heated sensor mounted in collector behind the header, not in the header.The 4. In the L20 version, the Tahoe and Yukon were upgraded to the 5.

The two engines tend to have similar problems, but the 4. The engine knock sensor sits on the intake manifold and is responsible for sensing vibrations caused by the engine. The knock sensor, as you could guess, functions to detect and prevent engine knock.

Fuel burns in pockets, almost like a row of fireworks. Pre-detonation, or knock, occurs when one of the pockets of fuel ignites before the its turn in the sequence. When this happens, it causes a shock or vibration throughout the cylinder which increases cylinder pressure. The sensors responsibility is to detect this knock and then alter the ignition and engine timing to prevent it from continuously happening.

On the 4. When you have a faulty knock sensor, the engine thinks it needs to alter timing despite there being no timing issues, which can lead to a number of performance issues.

Fortunately, if you have a faulty knock sensor, the solution is usually as simple as replacing it. Water pumps are an integral part of an engines cooling system. The water pump is responsible for flowing coolant throughout the engine cooling system to keep engine temps down. Heat is one of the most threatening elements to engine longevity. Therefore, failed water pumps can become serious problems if not dealt with once a problem arises.

But, most 4. Usually around k mile mark is when you will experience water pump failure, or begin to notice that the water pump is becoming slightly less effective. Water pumps can fail for a number of reasons: the internal impeller deteriorating, the pump bearing breaking, housing cracking, a bad gasket, etc. However, failure symptoms remain the same despite the reason for failure. For most car guys with some DIY experience, it should be relatively easy to replace your 4.

The fuel pump sits in the gas tank and not only sends fuel to the injectors, but is also responsible for keeping the fuel inside the injectors highly pressurized. Given how highly pressurized the injectors need to be, the fuel pump tends to remain under a lot of stress while an engine is running. When a fuel pump fails, it either stops sending fuel to the injectors, or it cannot keep the fuel pressure high enough.

Obviously, when it stops sending fuel, the engine gets starved of fuel. While there have been a number of instances of people killing 3 fuel pumps in a matter of 10, miles, this is very rare. For the most part, the fuel pumps hold up until k miles or so until they begin to fail or noticeably deteriorate. With most high 4. Outside of the pump failing on its own, the fuel pump control module has been known to go bad on the 4.

The control module is responsible for communicating with the fuel pump and telling it how much fuel to send to the injectors. When the control module fails, it relays incorrect fueling info to the fuel pump.

Similar to the 5. The intake manifold control the flow of the air entering the engine and distributes it to each of the 8 engine cylinders.

On both of these engines, the manifold is made of plastic which makes it prone to cracking. The mainfold can crack or warp from excessive heat or also from being overtorqued.

Most of the time, problems arise from common wear and tear as they sit right next to the engine where there is a lot of heat produced. A cracked manifold or a bad gasket causes air leaks. When air leaks, it leaks prior to getting to the engine. The Vortec is a complete workhouse and overall a very reliable engine.Department of Transpertation.

Grab yourself a beverage of your choice, sit back and relax. Keep reading to have all of your questions answered. To understand what you're doing when you modify or repair the factory crank case ventilation system you should know how the factory systems works first before diving into modifying it or fixing it.

It might also be nice to understand the history and evolution of the crank case ventilation system, so I'm going to start with the early SR20DE system and work up from there. I know people like images so I won't hold off any longer.

Here's the factory system click image for larger display :. Now let me explain what's happening here. The piston rings don't seal perfectly, so there is some air that gets by them and we call that blow-by. This blow-by air is pressurized and will cause oil seals to fail and eventually will cause other major problems so it needs to be dealt with.

Having a vacuum in the crank case is very good as it promotes ring seal and keeps windage losses drag on the rotating crank caused by a cloud of oil in the crank case to a minimum. Since having a vacuum in the crank case is good and having pressure there is bad, we must get rid of the pressure somehow.

The air comes in contact with a lot of oil in the crank case and basically turns into a mix of air and oil along with a little bit of gasoline and water.

Car Engine Crankcase Ventilation System

I even showed little oil droplets condensing out of the air as it goes up through the "catch can" oil separator. I didn't show them everywhere in all the baffles, but you can imagine the same thing happening everywhere you see baffles.

The amount of air and oil can be quite significant, so Nissan put in two important pathways for the pressure to escape from the crank case because at times there can be a lot of air to evacuate. On the left the air and oil can escape the crank case up along the timing chain portion of the block and into the valve cover. This is the usual pathway for the air to take. On the right the oily air can escape the crank case in times where there is excessive pressure to evacuate through the provision in the side of the block, up through the oil separator catch can leaving the crank case.

So the goal is to have a vacuum in the crank case, and this is accomplished on some vehicles with a dry sump oil systembut on regular vehicles the intake manifold is used for the source of vacuum.

Basically the engine is setup to consume it's own blow-by gasses. Not a super great idea, but certainly efficient, practical, and good for the environment.The best thing about Chevrolet's 5.

These engines, present in Chevrolet's line of pickup trucks and SUVs, can be built into LS-series engines with the addition of a few off-the shelf GM parts, or they can be built into powerful engines in their own right with aftermarket parts.

There's no end to the variations that exist in making the 5. The gains are only limited by your imagination and your wallet. Install the basics to begin transforming the 5. A high-flow cold air intake is the most basic modification necessary to increase the speed of these engines. Install a high-flow cat-back exhaust system. This device bolts into place with common hand tools such as a socket set and can be installed in as little as an afternoon.

Install a reprogrammed computer. A reprogrammed computer is vital to build horsepower in computer-controlled engines. Install a set of ceramic-coated headers to further improve exhaust efficiency.

Headers from the factory are always built to conform to two parameters: efficiency of exhaust removal from the engine and low cost to construct. Aftermarket companies have the luxury of working without cost constraints, and so they can be far more lavish in the design of their headers. Replace the intake manifold with an LS1 unit. The LS1 engine intakes were built primarily for the Camaro, Corvette, and Firebird, but have since been retrofitted to the 5.

These intakes require changes to the air intake, but can increase horsepower dramatically when used in conjunction with Chevrolet's Vortec cylinder heads. Use GM performance products parts for the best fit and finish. Upgrade the valve train of the 5. If you are unfamiliar with this process, it is employ the services of an engine specialist, because this procedure requires the removal of sensitive engine parts and should not be undertaken by inexperienced shade tree mechanics.

I know I could get the parts much cheaper at an auto parts store like NAPA, and then find someone to do the work at a better rate. The only concern I have is the difference in the quality of the parts. Will there be any? Ive been looking for performance parts and any other kind of parts for my 97' el but i cant find a site were i can order anything.

Do you know a site i can order from for my acura. Loooking for performace parts and accessories. I want ignition set up, coil, cables, plugs. I have a Firebird 3. Will the '89 do me any good? Serious Answers Only Please. I currently "own" technically my dad does a Dodge Ram pickup that says Ramcharger on the fender badge.

The part sites I have looked on do not have a category for a specific 'Ramcharger' Dodge truck, oooh no, they have to be fancy and say D, W, so on and so forth, and I'm getting frustrated. The only parts sites that seem and I use this word lightly to have the parts, don't have parts for the right trim, I'm rebuilding an engine to a Toyota Celica ST, and I have been looking around for parts on online stores. I've even checked eBay motors, but most of the things that come up have nothing to do with the car.

Is there a good auto parts site that offers these parts at a good price?

Brand new parts would be better than used. I have an 89 conti and am sick of fighting with air suspension and am looking for compatible parts to convert it-an interchange list of parts IS VERY HARD or has been near impossible to locate. I am not interested in buying online conversion kits and I am aware that parts DO exist but I am so poor that this will have to I was looking at O'Reilly's and Auto Zone. They have so many to choose from.

Edited add - REASON is I need to understand the oil flow to the pressure sending unit and the little screen there, and the relationship to the rest of the oil system. Also, is this a full-flow filter system, or is there a bypass, or what? I'll see what I can find, might be tomorrow PM Just Common Sense This might answer most questions, looking at the oil passage diagram.

If you need something more specific, let me know by AM, and I can check midday Thanks but that site wants to charge me Just looking for an oil flow schematic NOW my oil pressure gauge is reading about 20psi, while system pressure is about 40psi. Suspect the screen on the pressure gauge sending unit is clogged.

Dunno, the page should open first, but alas Let's try this. Originally Posted By: CabinConnection. Lots more info here If so, internal or external bypass on the filter? Is that the dash gauge sensor AND the little screen that's underneath the sensor? Main relief is set at 65psi? Then it looks like the AFM relief steps it down again. Is this the 40psi that I see on the dash gauge? Then what does the VLOM circuit see? Thanks Bill!
