3.1L 240Z triple weber carb tuning (w/ new Stahl headers)
A collection of short clips / butt Dyno runs while tuning the triple Webers on my 3.1L 240Z. Open Exhaust. Unfortunately, I didn't have the benefit of an O2 sensor / AFR. All in all, I was pretty pleased with the final results, the new headers have really opened up the head's flow potential. Sounds good, too! :)
240Z vs. the Ozark Mountains
Some [conservative] horseplay in my 1971 3.1L 240Z before putting my new
race motor away for the winter. This is NOT a performance driving video,
just some fun on an awesome road.
This is first time I've driven the road, so I'm a little more confident
after 3:00. (I found it on Google Earth then trailered my car there.)
Some highlights, since it's not exactly a concise video:
1:55 downhill stretch, crossing Beaver Lake
2:40 more aggressive driving begins
4:00 scared myself a bit
4:40 traffic encountered
5:00 engine vs. open highway
Referenced walk-around video of my L6 motor:
My 240z on the dyno at Z bash
BTW i have an update video with the 3.1L installed. Just search "240z 3.1L
Stroker (Beta Build)"
I put down a max of 130.5rwhp and torque at about 135ish. L24 tripple 44s
untuned and unmuffled idle, 240Z 3.1 stroker
Quick demo of the new race headers (Stahl), at no point does the engine rev
above 3k rpm (despite how it sounds at 1:25). Other coincident upgrades
include titanium valve spring retainers, single valve springs (outer
springs only) that the cam was profiled for, and a crank/damper/flywheel
balance for 10,000 rpm.
And yes, that's coolant on the ground during the idle portion. Evidently I
didn't tighten one of the thermocouple housings all the way. Oops.
Between moving and other logistical challenges, I barely had the time to
get the new race motor installed and minimally operational before sticking
it back in the trailer for 6 months of storage, after which the engine

Nissan Project 370Z vs 1970 Datsun 240Z with RB26 Track Battle! - The Downshift Episode 54
Many months ago, Nissan asked their fans to help them create the ultimate
370Z track car. They called it Project 370Z. To put it to the test, Nissan
fans were asked to vote for a challenger to compete against it. They chose
a 1970 Datsun 240Z with an RB26 engine transplant built by Gordon MacSwain.
On this episode of The Downshift, we head to Las Vegas Motor Speedway for
an epic David vs Goliath battle between these two amazing machines.
The Downshift appears every other Tuesday on the Motor Trend channel.

240z vs Rx7
This was the third session of the day in HPDE3 on April 25, 2010. We saw
this Rx7 zipping around all weekend and finally caught up with it. Both
drivers were testing their limits and it was quite exciting being in the
car and experiencing this "battle" firsthand. Gee-Force Z spider got a good
workout too. Until next time little blue Rx7!
1970 Datsun 240Z/L28- 7000rpm in first three gears - triple Weber 40DCOEs
Watch for the surprise at the end (!)...didn't get pulled though. See
http://www.youtube.com/watch?v=RjpmkfdnNvI for the same engine with SU
carbs...which is a 1983 F54 L28 w/P90 turbo head, 10:1 compression, 15lb flywheel.
The engines sound similar but the Webers have much more torque than the
SUs, pull very hard in 1st and 2nd and easily to 7,000 in 3rd. I have a
Centerforce 2 clutch now which make changing gears a tick slower compared
to my earlier video however. The car is definitely faster through each gear with solid power to

1973 Datsun 240Z 4spd Start Up, Exhaust, and In Depth Tour
In this video I give a full in depth tour of the 1973 Datsun 240Z. I take
viewers on a close look through the interior and exterior of this car while
showing details, over viewing of features, and noting unique styling cues
to the vehicle itself. I also show the engine and the details of it, start
it up and see how it sounds under acceleration. A thorough tour/review of
this car designed to give others a greater overall appreciation of the

1972 Datsun 240Z run. (One last good time before I sold it)
Right before I sold it...
Clicking noise is a leak in the balancing tube (welded day after this
video) Some sloppy shifts due to slack in the rear end and un-adjusted
clutch with cracked clutch arm bracket.
I loved/love this car! So much fun to drive...
