The sos/rock 4X Fabrication Toyota drivetrain adapters used in the first part of our project utilized a sidekick bellhousing, so swapping in a matching 16-valve Suzuki engine would be a no-brainer. Looking over everything involved, the 16-valve engine would be the perfect candidate for Sami Supreme with only one exception. The progress on the rig to this point has been pretty rough on the budget, so unfortunately the engine swap would have to wait for now.
After looking at some other less expensive upgrade options to squeeze more power from the "little engine that could," a few alternative fuel delivery systems were discovered. The stock Samurai carburetor is the notorious culprit behind most brokendown, left-for-dead Samis and is by far the single most complex, problematic component on the entire vehicle. replacing this menace with something that provides more power, better fuel mileage, and the ability to operate on extreme angles would be a blessing.
There are actually quite a few options available to replace the stock carburetor. The list includes: retrofitted, stock electronic fuel injection, Weber carburetors, Bosch mechanical fuel injection, Harley-Davidson carburetors, and the one that caught our eye, the Wild Bore sidedraft setup from Samuraiguy.com. the Wild Bore setup utilizes four synchronized Mikuni sidedraft carburetors attached directly to the engine head with a custom aluminum intake manifold. the four large-bore Mikuni carburetors used in the kit are from '88-'02 Suzuki GSX-R motorcycles and are readily available at local salvage yards and online auctions for only a couple hundred dollars. Samuraiguy.com also offers a complete kit with tuned, rejetted carburetors included for easy bolt-on power.
The Wild Bore kit replaces the restrictive factory thermostat and housing with a custom inline thermostat designed to flow much better than the stock unit. | 
With the two supplied intake hoses connected to the thermostat, they are clamped to the ports on the intake manifold. | 
A bung with a fitting welded to the side of the fourth cylinder intake runner is connected to the factory brake booster vacuum hose. |
Next, the supplied carburetor connector boots are clamped onto the backside of the carburetors. | 
With everything ready to go, the carburetors can now be plugged into the intake runners. The custom-machined grooves and matching tongue in the connector boots ensure a tight, secure fit. | 
The complete Wild Bore kit also includes four chrome reusable filters for the ultimate race look. |
