This is an aftermarket catback exhaust swap on a 1996 mazda miata as shown to the left. All exhaust swaps will be similar with only small differences. Reasons for an exhaust swap can be a leaking stock exhaust or maybe just to have an increase in horsepower. Another good reason to replace the stock exhaust with an aftermarket one is the material used in aftermarket catback exhausts. The material used is generally stainless steel which will never rust as a stock one will. Horsepower increases will vary depending on the stock systems flow and if the engine is turbocharged or naturally aspirated.

If you can’t get or afford the price of gas and your fuel gauge looks like this often, you might want to try some different ideas to save gas or improve mileage. First always make sure your car is running as good as it can. This can be done by performing a tune up which generally consists of spark plugs, plug wires, air filter, fuel filter, and distributor cap and rotor if applicable. If you have a fuel injected car and the check engine light is on you may have a problem that is costing you a lot of extra fuel. The car will then be running in a “limp” mode which usually consists of using extra fuel for the safety of the engine. Things such as the oxygen sensor (o2) will cause the engine to use extra gas also.

Thermostat replacement is generally done if a car is overheating. The other possibility is that the car is no longer heating up correctly due to the thermostat sticking. Before changing the thermostat verify that the engine coolant is full and that the cooling fan is working when the car is up to temperature. You will also need to find out the recommended temperature of your car’s thermostat when you purchase it. This sunbird has a 3.1 liter v6 engine that will randomly overheat. Another possibility is that the water pump is bad. Removing the radiator cap (if possible) when it is cool, can some times be helpful to see if flow is occurring although it won’t always work.

Upgrading an old points type distributor to a hei which stands for high energy ignition can be a rewarding upgrade. This distributor is on a 1966 ford mustang with a 289 v-8 engine. The upgrade distributor is a msd unit made specifically for this engine, some people may use a distributor off of a newer model ford engine. Unlike points you will never need to adjust a high energy ignition because it will never degrade. The engine will run smoother due to the higher energy spark sent to the spark plug. The cylinder combustion will be much more complete due to the increased ignition spark energy of the new distributor.

A lot of cool cars were made in the 1980’s and many can be bought for cheap. Many of these sport cars can handle and perform equal or better than many new cars for similar or less money. There were impressive import and domestic cars and a reasonable variety of each. Lets go through a list of cars by their manufacturers starting with domestic cars. Unfortunately tightened emission specs limited the horsepower potential of the 1980’s era cars, so some cars will be judged more on their handling abilities. One way to beat the stricter emissions standards was to use a smaller engine with a turbo to increase the horsepower.

This is an intake manifold and carburetor (carb) swap for a 1966 mustang. The engine is a 289 ci v-8 engine. The stock intake manifold will be replaced with an edelbrock performer aluminum intake which is lighter and makes more horsepower. The stock carb or carburetor will be replaced with an aftermarket edelbrock carb. The new carb should make the car start and run better and maybe make a little more power also. The edelbrock carb has an electric choke which will idle high when it’s cold and then down when it’s warmed up. This carb is superior to the original.

After this engine sat for awhile it wouldn’t restart. This is a 2 horsepower briggs and stratton engine. This engine is on a rototiller, but the problem would be the same with any other engine. The first thing to do is to decide if the problem is fuel or spark related. These are the first problems to check for. First check the obvious thing like adding fresh gas to the tank. Generally if the problem is fuel related the engine will at least sputter. Another way to test this is to remove the spark plug and squirt a small amount of gas in the cylinder, replace plug. If the engine starts but doesn’t stay running you have a carb or fuel issue. If it still does nothing you should remove the spark plug and lay it on the cylinder head. Then you probably have no spark and have an ignition problem.
