From “Electronic Fuel Injection, MAF and MAP Sensors – EFI Basics Tech”:

Imagine a turbocharger trying to pressurize a carburetor with its small venturis and finicky floats and you can get some idea why electronic fuel injection opened the door to big boost, big power, big reliability, big fuel economy and a cleaner burn.

And an article on wheel alignment which is a must-read for all drifters & racers plus anyone concerned with safety or mileage: Wheel Alignment – Camber, Caster, and Toe

Having the straightest wheel alignment will give your tires the largest contact patch as well as the most even treadwear. But when it comes down to having low offsets, big lips and wide wheels, you can’t always find wheels that will meet your fenders perfectly. Adjusting your camber is one method to adjusting your stance. But before you do that, you should know some of the basics to suspension and wheel tuning.

[About the gearhead:]

Bill Caswell, an unemployed Chicago racing freak, entered the Mexico round of the World Rally Championship in a 1991 BMW 318i that he found on Craigslist. The car cost $500. …

[About the race itself:]

Oh, yeah: The cops shut the highway and city streets down so we could get from city to city fast.

From Title To Tune Up In 6 Days

When I bought my 1st 4Runner (already 20+ years old and poorly maintained by previous owners), it was leaking coolant and overheating. Within a week I removed the entire cooling system, all the belts and everything else in front of the block. Now, I’m a mechanical person by nature – I love to take things apart and see how they work. But I had never worked on a Toyota engine before in my life. Everything I needed to learn was available online, for free. The 2 most useful resources, beyond a doubt, have been the YotaTech Forums and the Factory Service Manual (FSM). Another vital resource is the local flea market – a treasure trove of quality tools at bargain prices. Every time I got stuck on a part I couldn’t budge, I went to the flea market in search of tools I didn’t know existed until I saw them. This is how I finally loosened the 181 ft/lb of torque holding the crankshaft pulley bolt on plus countless nuts & bolts in hard-to-reach spaces.
