In our last installment of Ported & Flowed (October 2004), we mentioned that our next step would be to put the computer model to the test. This test would occur when we installed the ported cylinder head along with the camshafts on our GT-R. Then we would optimize the fuel and ignition curves for the new setup. The question that this exercise would answer is “Will the real-world numbers match the computer prediction?”.

You’ve probably been told or heard from someone that “an internal combustion automotive engine is just a sophisticated air pump.” Here’s the truth. What you have been told isn’t entirely accurate. First, a pump is a device used to move fluids and it operates at relatively low pressures. Air is not a fluid, but instead a gaseous mixture. Second, the primary purpose of an internal combustion engine is not to pump fluids or compress air. The engine’s purpose is to perform energy conversions to produce horsepower. Internal combustion engines turn the chemical energy in the fuel into thermal-pressure energy in…

Last issue, we said “when we get back on the dyno, we won’t be surprised to see 500-plus horsepower on 91-octane with a boost and power curves that we never believed possible with turbos so big. As predicted, we accomplished our mission with 505 horsepower registering on the dyno after fixing our exhaust leak, crafting a new intake system and spending some more time on the dyno. This taste of success motivated us to make a long overdue trip to the dragstrip. Text & Photos by Michael Ferrara Dyno Time Our previous visit to the dyno proved to be more…

Giant peak horsepower figures made on race gas make for great headlines. Just the mention of a “1000-horsepower Supra”, “740-horsepower WRX” or “500- horsepower EVO” draws attention. While peak horsepower numbers are real and exciting to any enthusiast, these high- caliber numbers tend to distort the total performance picture. This picture becomes blurred since few enthusiasts understand the performance difference attainable between 91-octane pump gas and 117-octane racing fuel. The fact is that swings of anywhere from 50 to 500 horsepower can be seen on turbocharged vehicles when the fuel is changed from pump gas to race gas. While the…

We almost forgot why our Project RH9 Skyline GT-R was our dream car. With a broken factory transmission, our Project RH9 GT-R went from its daily- driven, head-turning glory to a very-large obstacle in our garage. While obtaining another factory transmission would have had us back on the road in the least amount of time, it would have only been a band-aid and not a fix. Our fix would be to upgrade the factory transmission to a Holinger 6-speed sequential gearbox. Thanks to the cooperative efforts of Holinger, Exedy, AEBS (TOMEI ), Blast Racing, Motorex and XS Engineering, Project RH9…

Guess what broke on Project RH9? Another factory transmission. Old school Turbo readers might be seeing visions of another Project Talon in the works. To be honest, I’m picturing the same thing. Text & Photos by Michael Ferrara Back in the days, Project Talon chewed up every single available transmission in the Southern California area. All totaled, close to $10,000 was invested in factory transmissions that couldn’t last a full pass. Learning from our lessons of yesteryear, we decided to research our transmission options for our GT-R. The Close-Ratio Aftermarket Gear Sets A number of companies produce aftermarket gear sets…

Call us a little crazy. No. Instead, just call us insane. As we continue to improve the performance of our Project GT-R, we also continue to raise our goals. In many ways, this project mirrors our experience with the magazine as a whole. We make progress every issue and we continue to raise our standards. Photos by Phil Lam | Text by Michael Ferrara When we began this project, our goal was simple: to build America’s first RH9 GT-R. To qualify for RH9 status, our GT-R would have to run a 9-second quarter-mile time on radial tires. Although this was…

Last month, we promised to upgrade the fuel system, do a compression check, do a leak-down test and more to figure out why our GT-R had made a step backwards in terms of power output. We were then going to strap the car back on the dyno and give it another flogging. Text & Photos by Michael Ferrara Guess what? We didn’t get it all done. However, we are seeing some major improvements and some problems solved as we progress. Sharing these with you will hopefully allow you to avoid some of these problems on your own street or racecar.…

The orders have been placed, but parts delivery for the GT-R is taking longer than expected. This downtime has enabled us to get back on the same DynoJet chassis dynamometer at XS Engineering to evaluate the performance of the engine with the smaller P13 turbine housings in place. As it would turn out, the extra dyno time has proven to be a blessing (or curse) in disguise. While making the passes on the dyno, we have discovered that our GT-R has now developed some high rpm issues. Text & Photos by Michael Ferrara The P13 Turbine Housings Finally back on…

It’s the night before the biggest race of the year. The BFGoodrich Tires IDRC International Finals presented by ICEMAN Intakes is coming to Los Angeles and the DRAG Sport Project RH9 GT-R is going to be ready. The IDRC International Finals mark the biggest import drag racing event on the West Coast and this year would prove to be no different. Text & Photos by Michael Ferrara New Housings…New Tuning We have changed the turbine housing to the smaller P13 units and now the tuning is no longer matched to the engine’s boost characteristics. It’s time for a trip to…

It’s official. We think we accidentally built the most-powerful GT-R in the U.S. At least, it’s the most powerful one that we know about. The previous record holder was the nitrous-fed “Big Bird” from Motorex. Big Bird generated 654 horsepower at the rear wheels. Text & Photos By Michael Ferrara So how did our DRAG Sport GT-R better the mark? With Eric “Dai-Lo” Hsu of XS Engineering at the laptop, the A’pex Integration Power FC engine management system was dialed in to help our original RB26 longblock spin the tires to 655 horsepower at 1.58bar (23 psi) of boost pressure.…

Meet our DRAG Sport Project GT-R. This is a 1996 Nissan Skyline GT-R V- spec. Before the turbocharger upgrade that you are about to see, the car generated almost 380 horsepower at the wheels. That’s enough to run in the 112-116mph range in the quarter mile, with low 12-second elapsed times. However, that’s not close to being good enough for DRAG Sport’s project GT-R. Text & Photos By Michael Ferrara Our plan with the project is to build a 10-second GT-R using the stock long- block and then build the car to run in the 9s with a built engine.…

Whether you drive a Honda or not, the term VTEC is something you’ve probably heard of either in a joke, seen in an internet “meme” or plastered on the side of a car accompanied by the letters D, O, H and C. It’s not high horsepower, large displacement or even turbocharged from the factory. However, the B-series engine introduced the world to Honda’s revolutionary Variable Valve Timing and Li Electronic Control (VTEC) technology. VTEC gave the B-series engines the equivalent of two di erent camsha profiles. The first cam profile offered low RPM response, good drivability and decent fuel economy.…

Since its release in 2012, the FR-S/BRZ has received an enormous amount of praise for its excellent chassis, abundance of aftermarket support and entry-level price point. Yet, both the press and enthusiasts unanimously agree that the power output of an unmodified FA20 engine leaves much to be desired. Instead of simply showing how to make the car look fast, DSPORT will show you how we put together a reliable, daily-driven combination to produce over 300 wheel horsepower.

Simon and Garfunkel, Ike and Tina Turner, Sonny and Cher, Cheech and Chong, Madonna and Sean Penn, Miley and Liam, J.Lo and Diddy, Justin and Britney. These were all famous couples that all made headlines, yet eventually split. The same can now be said for DSPORT and the FAME Civic. Call it creative differences or whatever you like, both sides will be focusing on their solo careers going forward. Fortunately, fans of DSPORT’s engineering approach to exploring the outer limits of Honda B-series power capabilities won’t be left out in the cold. Instead, we’ll be heating it up with the…
