Honda
The Honda Prelude may not be as popular as the Civic or the Integra, but it does have a rather large tuner following. One of the reasons that the Prelude isn’t as modified as often as other Hondas is that the model’s initial purchase price is considerably more than a Civic Si or Integra GS-R, since the Prelude was better appointed with options and a more powerful engine.
When a B16A-equipped CRX EF came into the Rage Performance shop for a Skunk2 intake manifold install, the crew dove into the job with a fury. With cameras at hand to document the swap (’88-’91 CRX) for your personal pleasure, the job took no time at all and the owner of this Honda is deliriously happy with the results.
These days, if you want to go fast on the track in a Honda, forced induction is almost a must, as most vehicles come with relatively small-displacement engines when compared to their domestic brethren. Basically, the more cylinder pressure and fuel that you can ignite, the faster you go. Admittedly, this all sounds pretty general, but for now, let’s roll with that thought.
In the case of a new Honda Civic Si (EP3), this owner wanted to enhance high-rpm power. The K20 engine with the new i-VTEC 2-liter powerplant has considerably more torque available in the lower part of the power band in comparison to the older B- and H-series VTEC engines. While the EP3 used here is primarily a street-driven machine, the owner plans on taking the car to the weekend dragstrip on occasion.
When it comes to performance, there is one steadfast rule: All the good air that goes into making horsepower must eventually find its way out. This means that adding all the cool camshafts, intake manifolds and even superchargers to help improve airflow into the motor will be useless (okay, maybe not useless, but certainly much less effective) if the motor is not able to rid itself of the exhaust. Cork up a serious performance motor and watch it struggle and gag on its own exhaust fumes.
We all know and love the Honda/Acura B-series motors—and for good reason. They have been and continue to be the mainstay of the sport compact performance market. Sure, the new K-series motors are making headway with more and more performance pieces and they look to succeed the B-series once the supply of used motors becomes available in the quantities (and pricing) currently enjoyed by the B-series. But for now, Civic, CRX and Integra engine swappers, not to mention the horde of those originally so equipped, have made the B16A, B18A/B, B18C and B18C5 the performance Honda motors of choice.
Previously, we detailed the buildup and dyno test of a 475hp turbo B16A (“Boosted B-Series,” p. 50). Designed for street use, the turbo B16A represented what could be accomplished by combining an efficient normally aspirated motor with the benefits of turbocharging. By taking an already healthy normally aspirated motor, we had a head start to producing big power once we upped the boost pressure with our Innovative T04E-46 turbo. But what is necessary to take power to the next level?
