This is the fifth installment to our War Wagon build up. The infamous Bisi Ezerioha of Bisimoto has set track records with his drag SOHC Honda engines. Off the strip, he's set out to build the most badass five-door hatchback you will ever see. His goal, 700whp on a street-driven SOHC 1.6L engine. This month we break the engine in and do a trial dyno run on low amounts of boost.
After all the engine plumbing was done, in went the radiator cooling fluids and Torco TBO 40 Premium break-in oil. Torco TBO is recommended to be run for 30 minutes or longer on new or rebuilt engines for racing, high performance or street applications; extremely good for running in engines prior to switching to synthetic-based motor oils. The Torco Break-in Oil is a blend of hydro-processed petroleum base stocks that clean and prepare new surfaces in the Bisimoto Engineering D16Z6 engine. Since the first start up of a new engine is critical to its life expectancy, TBO utilizes specially selected additives in order to protect vital engine parts during the first startup. TBO cleansing agents "scrub down" any contaminants left in new engines from the build process and assure good cleansing of the freshly-machined parts. Using protective anti-wear chemistry allowed mating surfaces to gently make contact during the first new startup of the Wagon.
Torco TBO provides the proper film for new bearing protection and is made to withstand viscosity breakdown in order to maintain an amazing hydrodynamic wedge. Torco TBO contains a high percentage of zinc anti-wear chemistry for proper valvetrain and new Bisimoto 3.6 cam break-in protection. I have used the TBO exclusively in all my builds, and the oil drains so dirty after the first dyno session, or so. Works impeccably well with less than a 2% ring leakdown after less than one hour. I was very skeptical at first, a few years ago when I experimented with it, but to my chagrin, it works extremely well.
After the break-in on the Dynapack dynamometer, we drained the dirty break-in oil, and filled up with Torco SR-1 Racing 10w-40 synthetic oil. A nice advantage of using the Dynapack dyno, is the keen advantage of having access to the "set speed" function: this allows a dyno operator to break in street and race engines by setting a predetermined RPM target, and varying the throttle accordingly. This also allows for impeccable tuning of partial throttle environments for the ultimate in drivability. Based on the power levels we anticipate, we also opted to upgrade the factory axles to a beefy set from Insane Shafts.
With some tuning on my part using the new AEM tuner software and the Series 2 AEM EMS, we were able to extract an amazing 389.9 whp and 255.3 wtq at the Turbonetics RG-45 wastegate pressure of 13 psi. With numbers like this at low boost, on unleaded pump fuel, without the activation of the AEM water-meth kit, we are in for a great ride and the possibility of exceeding our power goals! This example is a true testament of the reliable power that can be realized, if you choose the right parts for your build. With peak torque hovering in the 7400rpm range, and the horsepower at 8500rpm and still climbing, the Bisimoto Level 3.6 camshaft was performing its designed duty. Feel free to search YouTube for "bisimoto" to view some of our videos on the Super Street/Bisimoto Wagon tests.
With this much power on tap, we are pleased that we chose the Progress Suspension components covered last month. Tire choice is also key, and for the low boost setup, we opted for the new Toyo Extensa HP line of rubber. Many vehicle owners are surprised at replacement time when they discover their car was equipped with high performance tires, either from the dealer or previous owner. Replacing those tires can be costly and owners maybe tempted to compromise quality in order to save money. The clear solution is the Toyo Extensa HP with exceptional wear life, all-season handling, and high-quality at a remarkably low price. This cost effective, all-season, unidirectional tire incorporates sophisticated design elements such as Toyo Tires' Silent Wall(tm) for quiet operation on the road and T-mode(r) design technology to optimize performance and ride comfort. Additional features include four wide circumferential grooves and full depth grooves for excellent wet traction, interlocking tread blocks to enhance stability and cornering and a three-variable pitch design to minimize tread noise. Looks, safety, high-speed ratings, great traction, performance and cost-effectiveness: what more could you ask for? The Extensa HP is also designed to compliment a performance vehicle with a stylish sidewall and tread design, and the virgin blue and red markings even compliment our Racing Beat Superlative wheels. These era-specific 15x7" wheels commemorated the Land Speed Record held by Racing Beat, and were manufactured in Japan by Hart wheels. A very rare wheel, of which, only five sets were rumored to have hit the shores of the US in the popular 4x100 pattern.
In high-boost street trim, we chose the Toyo T1R tires as our poison. The Proxes T1R is an ultra-high performance tire designed exclusively for high-end sport sedans and coupes. The 195/45R15 tires feature a refined tread design and construction that offers improved dry and wet handling and performance. The parallel shoulder silts help reduce irregular wear, and look great on the custom Bisimoto "Fighter Special" Spin Werkes wheels. These championship white wheels are made of spun aluminum drums and forged aluminum centers, and sturdy enough for street duty, albeit being extremely lightweight in nature. With a 0 offset in the front and a healthy -6 offset in the rear, coupled with the Buddy Club Steel Racing Lug Nuts, they give the Bisimoto wagon a wicked stance.
Rounding off the cosmetics are a Wek-sos front lip, JDM EF hatch mid-wing and a Golden Eagle rear tow hook. In low-boost street trim, the Wagon has the factory Honda "sleeper" bumper, however in full high-boost attire, the custom "bird-catching" cut-out front bumper will be in session. This bumper mod was also performed by Rueda Custom Paint. This will allow optimal heat exchange for the Turbonetics Spearco intercooler, and keep the Bisimoto Wagon's intake charge temperatures in check.
Next issue, we will crank up the boost, with some tech mods to ensure safety at those boost levels. Stay Super Street tuned!
