Rewrite
[edit]I rewrote the article in a way that seems to make sense; however although familiar with the terminology describing engines, I am not personally familiar with the engines or cars mentioned so someone knowledgable should check the information. Some of the stats have been struck out because they are obviously nonsense (110L capacity for an intercooler? Please...), and I removed approximately a quarter of the stats, as they made no sense at all. In my opinion even the stats that remain give excessive detail but if anyone can make sense of the stats I removed then please re-add them.
Also, I combined the opening paragraphs with the final paragraph. I had to make some changes as the information appeared to be contradictory, so again this needs verification. Archiewood (talk) 04:16, 24 November 2008 (UTC)

The MA09ERT is a mass-produced SOHC internal combustion engine manufactured by Nissan Motors. It is a series-charged design (possessing both a turbocharger and a supercharger), seldom seen in Japanese vehicles.[1]
Description
[edit]The "Nissan PLASMA" (Powerful & Economic, Light, Accurate, Silent, Mighty, Advanced) MA09ERT was based on the K10ET engine; Nissan attempted to improve performance and response by adding a supercharger to the (already turbocharged) MA10ET engine, which is a four-cylinder water-cooled OHC engine with a V-type valve arrangement and hemispherical combustion chambers, with sequential fuel injection.
The supercharger improved the response and the output in the low-rpm region (where turbochargers are typically less effective), and a new larger HT10 turbocharger aimed to improve output in the high-rpm regions. An intercooler and an updated intake manifold were added, the latter having a much larger throttle body and improved fuel rail. The result was an increase in output to 110ps (roughly 108bhp) from 74ps, and a much broader range of torque. Other changes included a reduction of engine capacity from 988 cc to 930 cc; this strengthened the engine by increasing the bore wall thicknesses by 1 mm, and allowed cars using it to enter competition classes not otherwise possible due to rules on forced induction.
The first prototypes of these engines were installed in the March Superturbo R/March R (EK10FR type) in 1988, shortly after the engine was installed in the March Superturbo.
The MA09ERT was the first series-charged engine available in Japan; series charging combines the increased low-speed torque of supercharging with the increased high-speed torque and power of turbocharging. The presence of the supercharger also mimizes the effects of turbo lag.
