Nissan GT-R Engine Assembly
Here are some quick scenes from the Nissan Yokohama engine plant's Clean
Room. It takes an average of 100 minutes for an engine master to assemble
one engine. Each man diligently checks and records the torque spec of
every critical nut and bolt, and the data is stored for the life of the

New modern GDI or gasoline direct injection high pressure pumps can be of
two types, the three piston pump and the more common single piston pump,
with a pressure and volume control solenoid. This single piston GDI High
Pressure Fuel Pump is suitable for most homogeneous and stratified
combustion gasoline direct injection engine schemes. Its roller follower or
tappet cam drive plunger designs reduce friction and contribute to fuel
economy and greater power. The pump is an engine driven, on-demand control
pump that features a single-piston and integrated design, also supporting a
wide range of engine software maps. It delivers operating pressure from 30
bar to 200 bar, or 100 to 2900 PSI. These pumps offer a high flow
capability for larger displacement engines. GDi Fuel Pumps includes an
integrated flow control valve for accurate fuel control and an integrated
overpressure relief valve. A one way valve is also included, which helps
maintain the fuel rail internal pressure.
Seen here we can see the cam lobe actuating on the GDI high pressure pump
plunger and piston. Upon simple observation it is a normal piston pump,
with nothing extraordinary about it. However, the key component here is the
fuel pressure control solenoid to the right of the pump side. The ingenious
ingredient here is the high processing power of the ECM used to control the
pump solenoid. The idea is for the ECM to .... Get the whole story right

How modern technology can increase horsepower and gas mileage at the same time.
Emmy Award winning mechanic Scotty Kilmer shows how Fords new ecoBoost gasoline direct injection system can
increase horsepower and get better
gas mileage at the same time. The trick is high pressure direct injection
into the engine cylinders.And, If you like my car help, be sure to watch

Fuel Trim (SFT/LFT) vs. O2S B1S2
Me and my friends (Colleagues) repeatedly faced with the fact that the
faulty O2S B1S2 (downstream Oxygen Sensor) was the cause of the DTC P0171
on Lexus RX300 2001MY.
This video (Russian with English Subtitles) shows some of the checking ECM
parameters with faulty probe ( O2S B1S2), by using the "downsream O2S
simulator", before and after installing a new O2S B1S2, and the results of
the active test "A/F Control" by Toyota Techstream.
900hp Silvia Part 2
Actually works out to be 980hp at the engine from our calculations! Tuning
it with more Boost for the drags
with an 8 second pass on radials as the goal.

Got bored on the way home from work one night in Taiwan, though why not
make a youtube video. My ceffy is stock, and unfortunately the underpowered
2.0ltr v6 but its better with the AC off hehe, and sounds great!
