Question

Where should I go to have these modifications done? Would a regular auto repair shop be sufficient?

Community Answer

Depending on your location, you may be able to find a few performance-oriented shops that would be happy to modify your vehicle. Some car enthusiasts prefer to do it themselves rather than pay big bucks to have a shop install modifications. By learning how to work on your own car, you'll know exactly what is and isn't in it, and, if you need to go to a shop for more advanced improvements, can thus avoid being ripped off.

Question

Do I have to do any internal work to my engine before installing a turbo kit?

Community Answer

It depends on the engine, but in general no, you don't have to. As long as you keep boost levels conservative, you shouldn't have to modify internals. If you want to run some high boost and have it last (generally above 8 to 11psi), you will want to invest in a forged motor.

Question

My idle is too low when I stop, and my car stalls out before I am able to begin driving again. My motor is also very noisy. Do you have any suggestions for me?

Community Answer

If it's carbureted, you can adjust how much air and gas goes through at idle on the carburetor. This will make you idle at a higher RPM and you shouldn't stall out when you go to take off.

Question

Why should I include an intake cooler in the car?

Community Answer

Cold air is more dense that warm or hot air. That means there is more oxygen in the same amount of space, which will make the engine run hotter and produce more horsepower.

Question

How can I boost my turbo charged 2500cc Pajero safely?

Community Answer

Adjust the turbo to put out more psi. But the factory probably has it at the right ratings, and boosting it more could harm the engine. You could add forged pistons crankshaft rods instead (though that's expensive).

Do any of the methods above damage the engine? Also, can turbo charging the car lead to harm?

Nitrous kits can destroy the engine if not set up correctly. Also, turbo charging an engine will reduce its lifespan.

Question

Is it possible to upgrade a transmission?

Community Answer

"Upgrade" isn't be the correct term -- you could maybe swap it out for a different transmission with pro short gears. If you're on a budget, put top notch transmission fluid in the car instead.

Start with adding xenon headlights. Change the muffler to add extra noise. Work with a mechanic to learn the basics.

Question

I have a Nissan Versa. How can I increase the hp, speed, and acceleration and still maintain its fuel efficiency?

Community Answer

You should get maybe a transmission swap for pro short gears. Get a smaller engine and try installing turbo chargers in your car.

When I press full throttle in park or neutral, my car will go only 3500 rpm. I want it to go 7000 rpm. What should I do to get this performance?

Reprogram your car's computer to adjust your rev limiter. Don't break your engine, though.

Question

Is it possible to place the body of a Nissan Vanette on a 4x4 chassis for modification?

Community Answer

It depends on your 4x4 chassis. With enough extra parts, welding, and fabrication, it should be doable. It is not possible to place the body of the Vanette directly onto your chassis, as it will cause major structural issues. Instead, try to fit the differentials and driveshafts under the car with brackets and other parts.
