The DeLorean – Back From the Past Part II

This article explores performance modifications that have been developed for the DeLorean from the time of its release to the present day. Although anything is possible, performance modifications over the past 30 years have focused primarily on the areas of engine modification (or replacement), and suspension modifications. I won’t be getting into time travel modifications – those are beyond the scope of this article.

Tech Tip: Exhaust Restriction Leads to Turbo Destruction

Turbos in gasoline applications operate at extremely high temperatures and RPM. If the exhaust stream, including the catalytic converter, is even partially blocked, the increase in exhaust backpressure can lead to thrust bearing failure.

Tech Tip: Performance Diesel Engine Service Notes

Diesels are setting all kinds of records from land speed to elapsed time. So if you’re not already dabbling in diesel performance, you may be soon. Diesel engines are a different type of animal when compared to gasoline engines. While both use the same four-stroke cycle of combustion, diesels use the heat of compression rather than a spark to ignite the air/fuel mixture.
