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! :)

Edge DE on Sunday Jan 13, 2013
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

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:
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...

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.

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
Sunburst 240z | Jonathan Buhler
We had the idea to shoot Jonathan's Z with his fiance modeling in it (which
she is shown 2 times in the video), but with them being so busy with
college classes and definitely with Jonathan getting ready to graduate
prior to this video, we didn't have much time to film what we wanted. We
did manage to get some clips shown in the video just because they asked me
to do a photo shoot of them. Towards the end of their semester, we finally
schedule a last shoot to finish things up, but unfortunately we didn't
because of unexpected calls of Jonathan's new job at Nissan. So we agreed
to just work with the clips I already have and honestly I think it came out
quite beautifully even though it's a small video, but videos don't always
have to be long. So here's the Sunburst orange 240z.
This gorgeous sunburst orange 240z has been worked on for so long by
Jonathan and his dad (I believe this is correct information) and I'm pretty
sure they are proud of what they have built up to this point. If you have
picked up Modified Magazine's June issue in 2011, you would have seen this
car feature along with his beloved Supra. Here's the article from the
magazine which you could find here
"Jonathan Buhler has car-guy blood in his veins. His father bought this '73
Datsun 240Z back in 1979 from the original owner (the classic first owner
tale of a little old lady who only drove it to the corner store and back),
and on Jonathan's 15th birthday passed it down to him since it had been
collecting dust in the family garage for eight years. Jonathan's other
ride, a '94 Supra TT 6-speed, purchased from his uncle in California,
recently met a less auspicious end.
When starting to restore the family Z, there weren't a lot of well-known
sources for S30 parts, but thanks to his local Nissan dealership Jonathan
was able to put his Z back in tiptop running condition. But, of course,
Jonathan had bigger plans than just a basic resto for his Z. "What you see
in these pictures is nowhere near the end for this project, but only time
and my college budget will tell when it'll be finished," he says. "It
already has a lot of my blood, sweat and tears rolled into it, and I'm
particularly proud of the fact that I've kept the original L-series motor
in it." No RB or SR swap for this Z purist, and if you've ever heard a
modified L24 straight-6 on full song, then you know why Jonathan has
decided to keep his in service.
As for his ill-fated Supra, Jonathan tells us, "After getting it off the
shipping truck, I started modding it with anything I could get my hands on.
I tried not to go overboard, though, keeping the body stock and leaving the
stock twins in place, instead going for more of the stance look. I guess I
hit the spot because my buddy Mike Burroughs from Stanceworks did a blog
feature on it. Sadly, last month I was involved in a pretty bad accident
and the Supra is no more. This car really meant a lot to me and to see her
gone is heartbreaking." Hopefully seeing her one last time on the pages of
Modified is a suitable farewell."
"Why We Picked It (Modified)
One of the all-time great Japanese sports cars, Jonathan Buhler has done a
bang-up job restoring and subtly updating the appearance of his 240Z.
Although we're partial to the bumperless and fender-flared look when it
comes to classic Fairladies, a bit of a motorsports-inspired exterior would
go nicely with the roll bar and SCCA-spec SU carbs. It's still tough to
fault the clean factory lines and sparking Sunset Orange paint on
