Performance DIY by DIY Guru

To calibrate the voltage on the TPS Sensor, a sensor on the throttle body that tells the ECU where the throttle is positioned. Over time the Tps goes out of calibration and your car's performance suffers greatly for it. I was VERY impressed with the difference this made to my car. It increased throttle response, smoothly revving across the whole rev range and makes for a far enjoyable car to drive. If your car is around the 8 year old mark, you should DEFINATELY do this if you want better performance from your car and offcoarse, who dosen't?! Again, I can't emphasize how effective this is, a must do! THE TPS IS OVERLOOKED OR SHOULD I SAY NOT UNDERSTOOD BUT THE TPS HOLDS GREAT BENEFITS WHEN CALIBRATED. This can be performed by yourself, without help, no problem. This is being done on a d16y4. Steps: Remove the Throttle body - 4 bolts 3 sensors that just unplug (TPS, Map and IACV) 2 coolant hoses on the bottom, unclip the metal clamp and pull the ho...

Found this video very informative,noob tuners have a go at it with the safc II

What is Fiber Glass ? Fiber glass is a reinforced composite plastic material which comprises of a woven material that is embedded with glass fibers which are randomly laid across each other and held together with a binding substance. Fiber glass is combined with a hardener resin to form an extremely strong and durable composite. When could you use fiber-glass? Following are some of the uses of Fiber Glass: Custom Sub boxes Custom door pods and speaker pods Custom dashboard and gauge pods Custom body kits Body kit repair Advantages of Fiber Glass Fiber glass allows greater flexibility and design Fiber glass allows better use of tight and unusually shaped areas Fiber glass is lighter Fiber glass is relatively cheap Fiber glass is very strong Disadvantages of Fiber Glass It can be daunting for a first timer. Dont be Afraid: Fiberglass can be a bit daunting for a beginner, but its very easy to get the hang of. The more you practice the more you will improve. Mo...

The complete lack of coverage on Vacuum gauges and their importance ....it isnt our fault ........changing times have prompted us to rely more on OBD scanners to diagnose engine problems where most of us forgot that the engine sitting nicely under our hood was still a hundred year old piece of marvel ......and before the days of the computer wizardry .......a competent mechanic using nothing more than your spark plug (colour) , compression tester and the vacuum gauge could track over a number of engine performance related issues today we will focus and talk about Vaccum gauges and how to use them....... Word of advice : Invest in one (buy one) Vacuum Gauge Though little understood, the vacuum gauge is probably the best single indicator of your engine's health you can get. When your car is idling-whether it's fuel injected or carbureted-the throttle plate or plates are restricting the amount of air the engine can breathe in. The pistons are attempting to ...

What is an Air/Fuel Ratio Gauge? An air–fuel ratio meter monitors the air–fuel ratio of an internal combustion engine . Also called air–fuel ratio gauge, air–fuel meter, or air–fuel gauge, it reads the voltage output of an oxygen sensor , sometimes also called AFR sensor or lambda sensor. How Air/Fuel Ratio Sensor Works Benefits of Installing an Air/Fuel Ratio Gauge Different Air/Fuel Ratio Gauges Available in the Market The One We Picked Tools Required for Installation Air/Fuel Ratio Gauge Installation Step-by-Step Tools: -Air/Fuel Gauge (I used an autometer sport) -1 wire 1 volt O2 sensor (narrowband Bosch) -Wire insulation -22mm Open End wrench -Extra 18gauge wire (any color) -PB Blaster (optional) -Wire taps (16-18 gauge) -Heat Shrink Tubing (Optional) -Zip Ties -Wire Crimper -Solder/Electric tape (or you could use those small red tubes that connect the wires together...ur choice) Step By Step 1: I didnt disconnect my battery so i just started o...

Engine Port Matching Principles and Basics Engine port matching helps make performance gains by making the airflow more streamlined. It is usually performed because the inlet and outlet ports on the engine block are usually larger than those of the manifolds that connect to them. This allows for scope in the manufacturing process to allow for mismatched alignment. Generally the engine ports are larger in the upstream flow direction avoiding turbulence but power gains can be made by matching these up. Most internal surfaces are far from smooth due to the casting process so small gains are there to be had by smoothing out the rough edges although polishing the insides offers little if any extra gain. Engines need to breathe as freely as possible and obstructions, seams and pits cause turbulence and this is not very good for airflow. Generally speaking most standard non performance cars will benefit greatly from even a little DIY head porting. A high performance engine ...

Nitrous Oxide I have to admit, I love Nitrous Oxide for use in dual purpose street cars. The reasons are simple:nitrous kits are cheap,it is easy to hide,and it is easy to tune and maintain. These reasons coupled with understanding how Nitrous works,and how to use it CORRECTLY make it a good performance booster. Nitrous adds power by adding extra oxygen in a compact form into an engine. Of course,to combust this extra oxygen you need a corresponding amount of extra fuel to accomplish this. Nitrous also cools down the intake charge,making it denser,thereby allowing more molecules per cylinder-making more power. There is no limit in how much liquid Nitrous Oxide you can get into a motor,but the motor itself can only take so much stress before it breaks something. Because nitrous increases cylinder pressure-a product of stuffing more oxygen into a cylinder,rods usually bend before anything else breaks. Running a Nitrous engine lean will cause "hot spots" on...
