Spring 2003 Project:
Crazy
Off-road's Big Orange Camo Monster
First of all let me say that there are two
main purposes for this write-up. One is to inform
Kevin Walker of how the progress is going on his big
orange baby and the other is to inform and entertain
readers interested in this type of engine swap. This
is also the ONLY write-up I have done that also
includes the customers actual opinion of the swap
which comes at the end of this page. I do want to
apologize to all of the anal retentive readers since
this write-up will not be nine pages like the
Sleeper Project, but more concise, because of the
lack of time I have these days with two youngsters
and running my aftermarket automotive business and
my Suzuki specialty business.
Here we go again. Another write-up about
another 16 valve install. Hmmm, so what makes this
one different? Well in this case it is the vehicle
as well as it's owner. This install is on one well
built Samurai that a lot of people know and have
seen wheeling at Zuwharrie and even roll-over at the
ZookiMelt last year. Most who see it just stare,
maybe because of the blinding orange camouflage
paintjob or because of all of the goodies installed
on it.
This Zuk should have "WIDE LOAD"
written on the back of it! lol!
With Dana 44 custom axles, 37" Swamper Boggers,
5.89 differential gears and a GRS-1 T-case as well
as a ton of other mods the Big Orange Camo Monster
goes just about anywhere. For a list of all it's
insane mods click on
http://www.crazyoffroad.com/samurai.htm. Kevin
has put alot of work into his Zuk and the next stage
is just beginning!
The donor vehicle is a 1996 Tracker in almost
perfect condition, but the Sammy needed the motor
more than the Tracker! It has only 40K miles on the
motor which runs perfectly and has with tons more
power than Kevin's old 1.3 and it runs like a
dream....the perfect engine to compliment a
well-built Sammy.
The motor was meticulously removed from the
white Tracker and prepped for installation into the
Big Orange Camo Monster in the background.
Here is a pic of the 1.3 Kevin had custom built
with a Swift GTI short block, a Sumo II head (which
was built before Asian Auto Parts actually started
calling it a SumoII head), a Doug Thorley header,
and a VW Solex carb with custom adapter to the
Samurai manifold.
The grill, and other vital parts
were removed to prevent damaging them upon removal
of the motor and tranny. Removal of the engine and
trans goes a bit easier this way and installation of
the 1.6 adapter kit is easier with the transmission
out. First the wiring, cables, lines and hoses from
the engine are removed as well as the power steering
bracket is unbolted off of the side of the engine
and set to the side. The antifreeze, engine and
transmission oil are drained, the electric fan, and
radiator are removed, the battery is disconnected,
and the coil is unscrewed off of the firewall.
The motor is hoisted out and if you look closely
you can see the drivers side motor mount about to
fall apart. This is an extremely common problem and
as many times as this Zuk has been on it's side I am
not surprised. It will be replaced with an early
model 1.6 motor mount which are noticeably heavier
duty and should not break the next time Kevin lays
her over.... LOL!
Lookin really empty in that engine compartment!
Centerforce clutch installed.
The 1996 1.6 16 valve engine ready to drop in.
(Kevin, are you drooling yet?)
The new gas tank with a 1996 Tracker fuel pump
installed in it.
The complete harness from the donor vehicle.
Time to start slicing and dicing!

Motor installation.
Kevin's opinion and
reflections of this engine swap in his own
words:
Well as most of you know the Suzuki Samurai is
not known for having a 632 cubic inch blown
alcohol injected motor. As many pro's as the
zuk does have, power is not one of them. Anyone
with a carb. knows how they act in off camber
situations and on the rocks. Finally I could
not stand my vehicle stalling anymore on steep
inclines. I had picked up a 4.3L Vortec about a
year ago and was contemplating putting that in
it. My rig already weighs 3,920 lbs. fully
loaded so I decided not to add that much more
weight to the pig. At Spring Zuwharrie 2002 I
drove Corey Bradford's zuk which had a 1.6L 16V
engine. I only drove it around the camp ground,
but was extremely satisfied with the power it
had. Well spring 2003 came around and Uncle
Sam was very good to me (thanks to the house I
had bought) and I started seaching for an
engine. Everything I found was missing this or
that, had too many miles on it, or smoked like a
freight train. I called Sean at Aftermarket 4x4
and priced out an engine. Just so happens he
had a low milage (40K) engine and he made me a
great package deal including the installation.
I really wanted to install it myself, but time
was very scare for me and Zuwharrie was only a
few weeks away. I hauled the zuk up to Sean's
shop and said goodbye to my little underpowered
friend.
For those of you who know me,
you know I usually don't let anyone wrench on my
zuk except for me. I had seen a couple of
vehicles that Sean had done and they looked
good, so I let him do the conversion.

The temperature was around 50 degrees and the
wind was blowing hard the morning I arrived at
Sean's to pick up the Zuk. He told me to hop in
and crank it up without touching the gas. I hit
the starter button one time and the beast came
to life.....and continued running without my
foot on the gas. If this had been the carb.
motor that I was used to, it would have been 5
minutes before I could have removed my foot from
the throttle or the engine would have died just
sitting there. About 5 seconds later Sean says
"Ok, let's take it for a test drive". I said
"OK". About 5 more seconds went by and Sean
asked me what I was waiting for? I told him
that I was waiting on it to warm up. He looked
at me with a bewildered look, rolled his eyes
and said " I've got 2 words for you ..... FUEL
INJECTED, now lets go. So the vehicle was
probably running for a total of 20 seconds or so
before I put it in gear and let out on the
clutch. To my amazement, it moved without any
hesitation. The old motor would have died
immediately. As we pulled out of Sean's
driveway, he pointed at a side street. I turned
on to the street and Sean told me to stop. I
stopped in the middle of the road and Sean told
me to take off like I was racing someone. I
looked at him like he was crazy. "Just do it!"
I took off. The tach hit 5 grand, I shifted
into second gear. The tach was at 5 grand again
so I shifted into 3rd. As the tach climed
effortlessly to 5 grand again, I let out of
it. I stopped the vehicle and looked in total
disbelief at Sean. My look was soon transformed
into a ear to ear smile. I asked Sean if he
installed the 1.6 or a 350 Chevy. He just
laughed. I could not believe that this little 4
cylinder could propel my 4,000 pound vehicle
that fast. Our next test was off-road.
I came up to
a 3 to 4 foot burm and Sean told me to put it in
4lo, 1st gear and let out on the clutch and
don't give it any gas. As I let out on the
clutch, the vehicle idled right up the burm
without me having to give it any gas.
I turned around and idled up the back side which
was even steeper. The motor never hesitated.
Sean then made me back down and just barely
punch it.

As the vehicle topped the crest, both front
tires were in the air. At this point, I could
not have been any happier.
I got the Zuk back from
Sean the weekend before Zuwharrie. I had 4 days
before I left for Zuwharrie. I needed to have
some exhaust work done and that didn't leave me
much time to really drive the Zuk. I put a
total of 150 yards on it before I unloaded it at
Zuwharrie. Once at Zuwharrie, I took the Zuk to
the Outpost. I was in 5th gear accelerating up
hills on the road. With the old motor I would
have already had to down shift into 3rd gear
while watching the speedometer fall steadily. I
was in friggin 5th gear watching the speedometer
go clockwise!!!! Once we hit the trails, my
excitement and love for the 1.6L 16V only grew.
On steep uphill climbs I used to have to use 1st
gear and turn around 5 to 7 thousand rpm. The
first big hill I was idling in 3rd gear at
approx 1200 to 1500 rpm with my foot barely
touching the gas. The rock piles and inclines
were no match for the fuel injection.
I can not stress how happy
I am with the way the 1.6L 16V engine performs.
I would strongly recommend this engine to anyone
with a Suzuki Samurai. Whether it's stock or
lifted, this engine is unbeatable. Sean did a
very professional job installing it and with the
exception of the exhaust (Sean's exhaust guy
was on vacation) and putting the computer in a
tupperware container to protect it from
moisture, the vehicle was turn key.
See you guys at Zuwharrie in the fall!
