Like many, you probably thought that once you bought your early Evo/DSM that it would be the end of money spent on it. Sure, maintenance would have to be done but the car was pretty quick from the off and you surely wouldn’t want it to go quicker. And then you upgrade one part and you can feel the difference it makes. Your mindset then changes to one of “I’ll just get this one upgrade, and then I’ll be happy with the power/handling” and before you realize it, you’ve spent the GDP of a small country on the car.
You will also need either access to a car lift, or the proper equipment to get your car off the ground to access the exhaust system. In the absence of a lift, you can use tire ramps and blocks. Do not use only a jack to lift your vehicle. If the jack fails or the car shifts, it will fall on you, potentially killing you. If you are using ramps, be sure to secure the emergency brake system, and place blocks behind the front tires to prevent the car from accidentally rolling for any reason.
Once you have determined the best choice have an oil change. Many mechanics recommend switching from 10W30 to 5W30 during freezing weather. The lower viscosity of the lubricant allows it to flow more quickly at very low temperatures. In addition to changing the weight you use consider using high quality lubricant if you don’t already. Many companies make a lubricant specific for winter or cold climates and it will reduce damage to the engine when it is started on freezing days.
Emissions are simply the exhaust or leftovers of combustion coming out of your vehicle’s engine. An emissions test is normally done with a probe placed into the exhaust tailpipe. The emission sampler will “sniff” or sample the contents of the exhaust coming out of the tailpipe. Every road going vehicle produced, has certain clean requirements that it is required to meet. This requirement is specified by EPA to limit the amount of pollutants exiting the vehicle.
Catalytic converters are popular for going bad. You should never start your car in a closed garage. Always open the door first and once started, drive it out of the garage. People have died from a faulty exhaust system. The muffler just drowns out the noise but without it, you your car will be really noisy.
Our current engines are so inefficient that we literally burn our cash. The EPA would have a heart attack if you got rid of your scrap catalytic converter price guide, and for a good reason. A large amount of our fuel is unused. Without a catalytic converter you’d be pouring gas onto the street right out of your muffler. The catalytic converter cooks all the unused fuel to improve emissions. Here’s how HHO nips that in the bud. The more efficient combustion while using HHO means less unused fuel. So much less that you don’t need your catalytic converter, and your HHO emissions turn into water. This alone improves MPG and cleans emissions, but this isn’t the only benefit it gets better.
Boooooooooooost! Yes, we’re almost at the point where we can turn up the boost. But how do you do it? The answer is a boost controller. There are 2 main types of boost controller, a simple manual controller or a more complex electronic boost controller. The former are cheaper and have a strong following in the DSM community, where the Hallman Boost Controller gets some excellent reviews. I opted for the extra features of the Blitz Dual SBC Spec S boost controller and haven’t looked back. Four different boost settings, a boost warning if it gets too high, and very accurate control of your boost has made it a no-brainer for me. The Spec S is also reasonably priced and is currently holding around 1.6bar of boost on my car without any problems.
Another thing to consider would be to but some sort of block heater or other warming device that will slowly bring the engine of the car up to temperature. This enables it to start better and with less effort than if it was started cold. They are simply plugged in overnight and keep the fluids at an operable temperature. In fact it is likely that when you go to have the winter oil change you will be able to have the mechanic install one for you.
