Lost motion assemblies are basically valve springs for the VTEC followers in your valvetrain. The normal intake/exhaust followers have valves and valve springs to press against so they're not flopping around all the time, but the VTEC followers don't. The LMAs help to control their movement. I took some pictures a year ago when I was swapping out my LMAs. I went ahead and marked one of them up real quick so you can see exactly where the LMAs sit and what they look like: The picture is of a B16 head with the cams removed. You can clearly see the cam journals and the retainers on top of the valve springs. The rubber banded items are the cam followers. The center one is the VTEC follower, and the ridge in the middle is what...

Think about what R/S means for a second. Rod length / Stroke length. All it says is that ideally your rods are 1.75 times the length of you stroke. Now if you stop and consider why that ratio is so "good". The longer your rods are compared to you stroke the smaller the angles are between vertical and rod position as the pistons travels up and down. Envision a cross section of an inline reciprocating piston engine. As the piston starts to climb from BDC the rod forms an angle with vertical at the wrist pin. If you have taken any physics this is pretty basic. Think of a force diagram illustrating the forces acting on the wrist pin ( for simplicity sake assume that the piston and wristpin are one unit). The larger the angle between...

Double Clutching Q: What is double clutching? A: You just watched "The Fast and the Furious" didn't you? Real answer: Double clutching is a downshifting technique that promotes smoother transitions and lower transmission wear. It is useful for road racing, prolonging transmission life, and giving you an overall smoother ride. In normal driving, with modern cars- you don't need to double clutch... ever. When you shift, these neat little devices called "synchronizers" or "synchromesh" (or whatever other name you want to give them) in your transmission help your shifting by matching the rotational speeds between meshing parts. Why do you need to match the speeds between transmission parts when you shift? Simple- they won't go...

Quick answer: Short block = the engine block without the head (block casting, pistons, rods, crank, etc.) Long block = the complete engine, including the head (engine from valve cover to oil pan) A short block and/or long block are NOT substitutes for what most companies sell as a "complete changeover package". These changeover packages typically include the transmission, ECU, and other accessories you'll need to make the engine run in your car. If you buy just the long block, you'd better have the transmission/wiring/ECU for your application- and if you buy just a short block, make sure you have the proper head as well.

Unsprung Weight - Part 2 By: Eric Albert Introduction In the first part of this series, we took a look at the effects of high unsprung weight on suspension and handeling. In this part, we will look at rotating mass. Be careful not to confuse unsprung mass with rotating mass. Reducing both is good, but they are not the same. Let's take a look. Rotational Inertia (or Momentum) Rotational inertia is a concept a bit more difficult to deal with than unsprung weight. Inertia can be thought of as why a car wants to keep rolling once moving, or remain in place once stopped (unless you forget to set the parking brake on that hill). I believe the terms momentum and inertia are interchangeable. The term “flywheel effect” also refers to these...

Unsprung Weight - Part 1 By: Eric Albert Introduction Every car built today has some type of suspension on it. Whether it's a double-wishbone or a MacPherson Strut design, we, as tuners, need to know a little more about suspension that just 'dropping' the chassis down a little bit. Let's take a deeper look at what exactly the job of your car's suspension is. Suspension on the Clock So we all know that suspension works. It works for you, but it never gets paid. In the same way as you and I work, we probably have different jobs. Suspension is no different. There are a few different ways your suspension works. The main job of your suspension is to suspend your car above the road. If that was the only reason for the existence of...

Quite simply, Torque - the twisting force per distance (e.g., lb/ft). "How much work can be done" Horsepower - a function that tracks the rate of how work is done. "How quick can work be done" Watch this for more information:

How to Change a Fuel Filter on an Accord I just got done changing the fuel filter on my 1994 Honda Accord, and it was a real pain. So, I thought that I would take a few minutes to write up a thread giving recommendations on how to make the job easier based on what I went through. I promise you, if you follow my advice, this job will be a lot easier. This is not a job that you want to embark on without sufficient knowledge and the right tools for the job. So, take a few minutes and read before getting yourself in a pickle. The fuel filter on the 1994 Accord is located directly below the master cylinder inside the engine compartment. There is a banjo bolt on the top, a flare nut fitted metal brake line on the back, and a bracket holding...

Here's a quick lesson into how and why you'd want to solidify your motor mounts. Let's start with a little bit of theory. Back in the day, engines were just bolted to the frame rails of the cars making for very little inter-chassis movement(engine moving inside the car). This was ok, because with a V8, the power hits every 45 degrees alone the axis so the vibration is distributed pretty evenly over a circle. However in I4 configurations, the power hits every 90 degrees of the crank turn and it's momentum sometimes is transferred forward or backward depending upon where in the cycle, each cylinder is. This is why they came up with rubber engine mounts, that look something like this: This flexibility makes it so that the harsh...

How to Solder In these photos I'm changing the plug connector and replacing a missing bulb socket on a taillight I got at the junkyard. That's not the point though. The point here is to show you guys how to solder. I see a lot of crap wiring out there. It's scary, it's just bad and there's no reason for it. Soldering doesn't require any expensive equipment or any great skill. It takes less than $50 for tools and supplies and maybe a couple hours practice. Tools Required: *100 Watt soldering "gun" from Sears or Radio Shack $30 **wire stripper from Harbor Freight $10 Supplies spool of .032 solder electric "black" tape ***spool of 18 gauge stranded wire inline fuse holder (depending on what you're trying to make) split loom aka...

There are two main battles about break-in. First, is the easy break in. Personally, I don't buy this anymore. But, for the record- here it is anyway. Let the engine idle for 10 min then idle at 2000 rpm for 10 min. turn car off and let it settle for about 5-10 min. 0-200 miles. Try to keep the highest rpm under 3000 rpm. Every 15-20 miles, spin the engine to 4500 rpm in first and sometimes in second gear. 200-400 miles. Try to keep the revs limited to 3500 rpm. Raise the revs rpm to 5500 with the same frequency as above. 400-600 miles. Go to 4000 rpm for driving limit. Raise the revs to 6000 - 6500 rpm and include 3rd gear pulls, same frequency as above. 600-800 miles. 4500 rpm driving limit. rev it to 7000 rpm and...

ECU Modes There are 2 main operation modes for the ECU. Open Loop OPEN LOOP - this is the mode your ECU is in until the coolant temperature and a couple other sensors get to operating values. The ECU also runs the car in open loop when you are at Wide Open Throttle (WOT) or if there is an error condition causing a check engine light. Limp Mode Open Loop can place the car into a fault condition called Limp Mode. The concept is that something is wrong and the ECU will allow you to 'limp home'. This means, rpm limit around 3k and pulls timing/fuel to generate just enough power to drive it home. This condition helps protect the engine components from further damage and saves you a tow to bring it home or to a shop for repair. If...

things to check compression fuel spark then you can break it down from there no compression? check the cam timing no fuel? check the injectors no spark? check the ignitor and so on and so forth til you find the problem

**Things You'll Need for the Setup*** You will need atleast the following... -Head Info You must use a B-series DOHC VTEC head. A Prelude H-series head will NOT work. You can choose a head from the following list by code.... --B16a1: this engine came in the 89-91 civic SiR and the Integra XSi in Japan. This is the easiest motor/head to use for 4th Gen civic (EF) swaps. --B16a2/3: this USDM motor came in in the 94-97 DelSol (a3) and is still available in the 99 Civic Si (a2). It was also available in Japan from 92 in the Civic with 170hp compared to the USDM models' 160hp. It has upgraded pistons and slightly more aggressive cams when compared to the B16a1. --B17a: came in the 92-93 USDM Integra GSR. This motor is kinda...
