GASKET, PORTED HEAD AND TEC3 SYSTEM. MORE TO COME ,,,, TO DATE 3/2/2009
STILL STOCK INTERNALS OVER 460HP AT THE TIRE WITH NEW FLYWHEEL AND
CLUTCH,, BIGGER THROTLE AND COOLER PIPES ,,,, ABOUT 28MPG WITH 460HP ON
TAP SIMPLY AMAZING, KEY IS CAREFUL TUNING,,, BUILDING STRONGER BLOCK FOR
MORE POWER TO COME...787-315-6380
350Z Twin Turbo - Forged Z - 525 WHP @ 14 PSI
NOTICE: Check the most recent videos.
*This video was made when the transmission was going out. It was supposed
to be a built tranny, but the company in Houston screwed me. It blew up on
1/4/2009 on the way to Las Vegas. It is now rebuilt and running strong.
Nissan 240SX SR20DET 611rwhp
This is a quick clip of my lil' brothers SR powered 240SX. His vehcile made
611rwhp on a MustangDyno (not the Dynojet "feel good" numbers).
Mods are Full T4 T67 turbo, carillo
rods, cp pistons, tons of fuel, AEM, 3.5" turboback, 96lb hour injectors, Twin Walbro 255lph
pumps, RPS turbomax clutch (6puck), ACT
flywheel, and others of course.
vq35de 240sx twin turbo
89 240SX 90% complete. To all doubters AND HATERS, HA HA. To all my
supporters, thanks for your encouragement. I know everyone is talking about
the RB26 and the SR-plenty, thanks but no thanks those 20 year old
technology and besides, the VQ can do it all at 600WHP all day and not
break a sweat. YES I ALREADY HAVE ALL THE ENGINE COMPONENTS TO BUILD MY
ENGINE FOR THAT POWER GOAL.

horsepower: The SR
creates far more horsepower then a turbocharged KA. Although the KA has a 25%
increase in displacement, the displacement is found in the stroke. The
larger stroke limits the KA's ability to rev as high as the SR. Since HP =
Torque(RPM)/5252 (torque @ a given RPM is multiplied by that RPM, then the
answer is divided by 5252) higher revs will create higher HP readings. (You
will notice on graphs that all engines have the same horsepower and torque at
Torque: The KA obviously creates far more low-end torque (created by the
bigger stroke). Since torque is what moves you, you would think the KA
would be the better choice. The SR, however, can easily overcome this loss
in low-end torque. Since the KA redlines at approximately 6,000 RPMs and
the SR at 7,500 RPMs the SR can create more low-end torque. How, you ask?
Well there are two kinds of torque, engine torque and gear torque. The KA
produces more engine torque and since the SR revs higher it can use a lower
gear ratio too build more gear torque. The gear torque quickly increases
the total torque output in a vehicle. Therefore, with the 25% increase in
RPMs, the SR can produce comparable low-end torque.
Weight: Obviously, this is a huge concern for any racer. Lighter weight
means quicker acceleration, deceleration, and better handling. The SR is an
all aluminum construction, while the KA has an iron block.
Technology: The KA is a truck engine. It uses a distributor and is fuel
injected. That is about the extent of its technology. The SR has direct
ignition, and continuously variable valve timing (late model SR20s). This
technology will give the SR a flatter torque curve then the KA.
I know the saying goes, "There is no replacement for cubic displacement,"
but I would take the SR over the KA any day of the week. Besides, what
would you rather have? A big block NASCAR engine or a F1 engine?
