Project Samurai – Carburetor & ECM

Many Samurai met their fate not in battle, but the junk yard due to failed emissions testing. The carburetor used was electronically controlled, a precursor to fuel injection. It is a Hitachi DFB306 2-barrel downdraft type carburetor with primary and secondary barrels.

The electronics used includes a secondary vacuum solenoid valve, EGR vacuum solenoid valve, idle up vacuum solenoid valve, float bowl vent solenoid, fuel cut solenoid valve, mixture control solenoid valve, altitude switch, under the hood temperature switch, engine temperature switch, O2 sensor, engine RPM, fifth gear switch and two throttle position switches.

The mixture control solenoid valve which is operated by the electrical signals from the Electronic Control Module (ECM) so as to maintain the optimum air fuel ratio of the primary slow and the primary main systems at all times. This type of carburetor was only used for a limited time period and most mechanics who are not familiar with them try to treat them as a conventional carburetor and have trouble.

The ECM is the brain that controls important functions of the engine. A Samurai can run without it, I have seen one that did, but the secondary, EGR, idle up, vent solenoid will not function and it will run rich with the mixture control valve not working. The ECM has a limp mode that will cause it to run full rich if there is a problem with the O2 sensor or other inputs. The ECM must be checked with the diagnostic feedback test prior to adjusting the carburetor.

In addition to the electronic controls there are numerous vacuum lines, switches and valves to check. A must is the float bowl vent tube nozzle. Vent tube nozzle (Suzuki part 13211-831Z0)

Project Samurai - Bypass Filtration

Some may suggest a bypass filter on a 1.3L Suzuki Samurai engine is overkill, but there are benefits beyond clean oil. For a small four quart system the quart increase in oil capacity is 25%. This helps the oil last longer, maintain proper viscosity and keeps the engine running cooler.

The Ea By-Pass Oil Filter (EaBP) provides the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine’s full-flow oil filter, the AMSOIL Ea By-Pass Filter operates by filtering oil on a “partial-flow” basis. It draws approximately 10 percent of the oil pump’s capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can’t remove. The AMSOIL Ea Bypass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

For our build we used a AMSOIL BMK-21 mounting kit, EaBP-90 and a Top Dog V available from http://paretopoint.com/item--TopDog-V--topdogv_s.html to make the bypass connection. This saved time and made a clean in and out path with out having to drill or alter the engine. The extra protection of the magnets in the Top Dog V are an added plus for protection. An AMSOIL full flow Ea15k51 was used in the stock location.

The result was a simple clean install in under one hour. Here is a quick video of another installation on an FJ. Top-Dog-Installation

FOR OIL TWINS AMSOIL DRIVER ZACH ZAUSS, RACING IS ALL IN THE FAMILY!

(July 1, 2011, Montclair, CA) When he was growing up, few people could argue that Oil Twins Amsoil sponsored driver Zach Zauss would one day drive a racecar. After all, the first year California Lightning Sprint Car Series driver's mom did some Indy style racing in Nevada, his grandfather raced Sprint Cars and his dad currently races Stocks Cars in Nevada and Northern California. This Saturday night, July 2nd, Zauss will be flying the Oil Twins Amsoil logo at "The Southern California Home to Major League Sprint Car Racing," Perris Auto Speedway.

Before 2011, Zauss, who was born and raised in Reno, Nevada, got in one race in a Lightning Sprint Car and one in a Super Stock. However, involvement with another sport is what finally pushed Zauss into the seat of a racecar. Bowling! Zauss is an accomplished bowler who has bowled in some PBA tournaments and he coaches kids every day. Last year, one of the young kegler's he was coaching was Hemet, California teenager Alexander Bissett, who was a rookie in the California Lightning Sprint Car Series. "Alexander told me to come out to the racetrack one night, so I came out and helped him work on the car," Zauss said by phone on Thursday afternoon. "The Bissett family asked me to come out and help at every race after that. I tinkered around with their car and helped them with the set up with some of the tricks of the trade my grandfather taught me. I then decided to get one of my own."

The plan was for Zauss to race the entire season with the CLS, but a little bump came up in the road after two races. "The Thursday night before one of our races, I was admitted into the local Rancho Springs Medical Hospital," Zauss stated. "I was then shipped off Kaiser in Riverside. I had a heart issue where my heart would shut off."

At first, it looked the personable racer was going to miss the balance of the season. However, the doctor recently cleared him for all normal activities. "I am taking medication for it and it is under control now. I have no problems."

When it appeared that Zauss was going to be out of his racecar for a while, CLS officials quickly offered him a job as a race night official. He accepted that position and now intends race some nights and officiate on others. "I still am kind of an official," he said while laughing. "I believe I am only going to race at the Perris races and as we travel to other tracks, I am going to be an official."

There is no hiding the Murrieta, California resident's zest to start racing again on Saturday night. "I am so excited to get back in the car," he enthused. "Ever since I got home from Vegas (Zauss was in Las Vegas last weekend coaching a huge kid's tournament) the mindset has changed from bowling to racing. The car is shining. I think it is cleaner than before I took it out for the first race. I have had an ear to ear grin every day this week. I wake up, sit in the garage and say, 'I am going to race my car again, hallelujah.'"

The 23-year-old met up with Andy Jones of the Oil Twins at an open practice session at Perris Auto Speedway in March. "Andy was getting some stickers ready to put on the "Red Hot Racing Grandma's" (fellow Oil Twins Amsoil driver Ronnie Everhart) car and I nudged Andy and said, "Hey, how about we get some Amsoil stickers up on this ride?' He said, 'absolutely.' He hung out with me and I went to some trade shows with him and at the Night of Destruction show at The PAS a few weeks ago, I signed on and became a dealer with Amsoil."

One of the reason's Zauss decided to become an Amsoil dealer was the quality of the product. "I used to run another product, but when I put Amsoil in, I noticed a significant change," he said. "The biggest change I noticed was in my tow rig. I drive a 1996 GMC 1500. I put the fuel injector cleaner into my truck and got six more miles to the gallon. I swear by the Amsoil product. I own six vehicles and every one of them has Amsoil running in it. In my tow rig and my racecar, every fluid and every grease product that I can get has the Amsoil label."

OIL TWINS AMSOIL DRIVER TO RACE TWO DIVSIONS AT PERRIS AUTO SPEEDWAY!

(June 23 2011, Montclair, CA) This Saturday night, June 25th, when the PASSCAR Stock Car Series rolls onto the track at the West Coast's premiere dirt oval, Perris Auto Speedway, racing fans will have two reasons to watch Oil Twins Amsoil racing star Steven "Bam Bam" Fangmeyer. The Corona, California based driver will not only be racing as usual in the American Factory Stock class, but he will be making his first ever appearance in the Street Stock division.

Fangmeyer's, association with the Riverside County oval goes back 13 years. When he was 12-years old, Fangmeyer and his father helped work on Ken Searcy's Super Stock. "My dad and some of his friends helped work on Ken's car," the 25-year-old racer said. "I was just a little kid hanging around the shop doing what I could do. Putting on tires and stuff like that."

Fangmeyer's association with Searcy grew until he eventually became crew chief on the blue and yellow #50 car when it won The PAS championship in 2009. While being a championship crew chief was very satisfying, Fangmeyer wanted more. He wanted a championship as a driver and in 2010, his second full season of racing, he parlayed his dream into reality when he was crowned PASSCAR Factory Stock champion.

This Saturday night he will expand his racing horizons again. In addition to competing in the Factory Stocks, he will take his first ever green flag in a Street Stock driving the Camaro normally raced by Jeremy Culp. It will be double duty at the track, but as the affable Fangmeyer explains, it is a lot of extra work getting two cars ready in the shop. "Between last week and this week, we have done two or three times the work getting the cars ready," he said via telephone on Wednesday afternoon. "It makes it harder with all of the little things you have to do. They pile up and you have to get them done."

2011 is Fangmeyer's second straight season racing with the Oil Twins Amsoil logo boldly emblazoned on his car. He is not only pleased with the sponsorship, but also with the fantastic results produced by Amsoil products and by the friendship he has made with Andy and Casey Jones of the Oil Twins. "When I won the last race in 2009, they joked around and Andy put an Amsoil sticker on my car," he said laughing. "For the first two races in 2010, my power steering system went to trash, so Andy said to try Amsoil and gave me some product. It worked on the power steering so then I went to the rear end. Their products worked there, too. Soon after and ever since, all of the fluids I run in my car have been produced by Amsoil. I wanted to pay him back somehow for helping me out and being a friend, so I signed up and now I am an Amsoil dealer, too."

Speaking for the Oil Twins, Andy Jones, talked about their relationship with Fangmeyer. "Steve is a joy to work with. The best about him is the passion he brings to whatever he is doing. Whether it is motorsports or his personal life, he always does it to the fullest."

In the short time since he began his racing career, Fangmeyer has quickly grown into a crowd favorite. Nicknamed "Bam Bam" for pounding on the roof of his car in victory circle after posting a win, Fangmeyer's popularity has not gone unnoticed by Perris promoter Don Kazarian. "Steven is a great racer to have around," Kazarian said. "He has a fun personality and the fans love him. Especially the kids. He is always a very positive guy."

In addition to his Stock Car endeavors, Fangmeyer has joined the pit crew of the Oil Twins sponsored #23 Sprint Car driven at Perris by rising young start Greg Alexander in the Amsoil USAC/CRA Series.

Spectator gates will open at 5:00 PM on Saturday and the first race will be at 5:30.
