Enginetiks a.k.a. Engtuning has closed its doors for business. The Lotus Honda swap project is moved to an undisclosed location for completion. An era ends. 2009-2014. Rest. Peace.

Engine Compartment Shield

Cleaned up the engine bay today: Thermo-tec acoustical / heat mat. Truthfully, it isn’t my ideal. I’d love a charcoal color that isn’t so wrinkled. Yet I don’t care for the common yet over-priced gold, race-evoking or not. Honda Motor Co. Logo ca. 1964: Continued »

Manifold Destiny: This Changes Everything

When Colin Chapman famously said “Adding power makes you faster on the straights. Subtracting weight makes you faster everywhere”, he was racing 400 horsepower, 1000lb F1 cars, in 1963. (Similar power-to-weight as the 2013 Arial Atom V8.) In this context his statement can be understood as a strategy for winning through faster cornering. Based on […] Continued »

When British racing car builders typically gave their designs their own name e.g. Cooper, Brabham, McLaren, etc., Chapman named his company Lotus Engineering Co. Why […] Continued »


A fiercely independent and sometimes rebellious teenager without formal mechanical training, but an abundance of talent, curiosity, and drive, left his village under Mount Fuji to find work in the big city as a mechanic. The year was 1921. He found an apprenticeship at an auto shop, and by age 22, he opened his own […] Continued »

Pulling The Toyota/Yamaha 2ZZ-GE

I’m not a mechanic and I could not do this myself. The most automotive maintenance I’d done was tune-ups and break pad replacements. And that was back in the ’80’s. This project is only possible because of my luck in meeting the team at Enginetiks. This is a unique project in a number of respects, […] Continued »


After some months (about 4 or 5k miles) I finally found a used Greddy supercharger/Katana mounting kit, on lotustalk. It arrived somewhat disheveled, but serviceable. A good friend–actually, good mechanic and a great friend–did the Lion’s share of the install in his garage. The effects were immediate, and inspiring. It didn’t take long to get […] Continued »

Stock, save for Bilstein Track Pack shocks (used) BOE toe links New A-arm bushings Braded oil lines/connectors Such a wonderful car to drive. All of the things a Lotus is known for and ‘should’ be: light, nimble, “spirited”, and precise. A extremely distinct-feeling car. A […] Continued »
