With three decades separating the present and the launch of the 1992-95 Honda Civic, arguably the most popular choice to modify of the entire 11-generation chassis bloodline, most every build these days involves some restoration along with modification. With that in mind, builders have to make a tough decision in terms of direction when they choose between the period correct approach and the option of adopting a more modernized style. Or, if they're anything like Roger Dejesus, they combine elements from both sides.

When Roger picked this 1994 Si up from a friend six years ago, he knew there would be plenty of time and money invested in converting it into a capable street car. "My friend Rick had it for over 10 years before selling it to me as a roller. It was painted about 15 years ago and had sat for a long time and though it needed a lot of work, I figured it was a great start." For the next few years, Roger chipped away at completing the interior and dealing with the car's wiring whenever he had free time.

Eager to get the car up and running, Roger went back and forth on whether to go the classic B-series route or prepare the bay for a more modern K-series. "I wanted something unique and old-school but with some new technology and parts," he says. For the old school part of that formula, a B20 VTEC combo was put together but it's the interesting shaft-driven supercharger that has the older crowd remembering the old days, and younger enthusiasts scratching their heads.

Today, supercharger kits are usually based around a Rotrex unit, but a few decades ago Vortech took one of their off-the-shelf units and positioned it on the transmission side of the DC2 Integra and EM1 Civic, and utilized a shaft that runs across the engine, just above the header, and connects to a drive unit mounted right next to the cam gears. The system provides a boost in horsepower and was praised for its instantaneous torque that Honda's B-series was known to lack.

The Vortech B-series kits are seldom seen these days, but Roger was determined to track one down. "I had a few notchback Mustangs in the past and one of them had a Vortech, so I wanted one for this engine. Finding one for the B-series was no joke—all of them were either beat up or missing parts, but I finally got lucky and found this one on OfferUp." Originally mounted to his B20 VTEC, the kit brought power up to 260 hp, but it wouldn't last long as the stock block called it quits in rather short order.

Before the downtime, Roger was dealing with cooling issues and heat soak that seemed to plague the boosted engine bay. "I started hitting up some friends and Henry at TwoStep Motorsports talked to Kevin about it and with everyone's input, we came up with the set up I have now." That set up now relies on an electric water pump that replaces the belt-driven unit, and a custom water-to-air system was fabricated by TwoStep Motorsports along with HL Customs' water reservoir and heat exchanger. With these changes, cooling issues are a thing of the past.

To replace that blown CR-V engine, a GS-R block was fitted with an LS crank, custom Traum pistons, and Eagle rods which bring displacement up to 1.9 liters. Additional period-correct goods can be found in the form of an Edelbrock Victor X intake manifold and throttle body, while modern touches include the aforementioned fab work and coil-on-plug conversion to do away with the B-series' notorious distributor issues. With Hondata's S300 allowing the fine tuning and KV Tuned behind the laptop, the supercharged combo is good for 391 hp with 235 lb-ft of torque. The car made an appearance on "THIS vs. THAT" last year to race a rear-wheel drive, turbo K20 EJ hatchback and proved its worth:

For the past few years, Roger's EH has maintained a relatively stock exterior beyond a rear wing but he decided to make some changes recently. He adds, "My friend Richard had a Mode Parfume kit he wasn't going to use and asked if I was interested. I took it and the plan was to install it on another car I'm working on. My buddy Erick stopped by my house one day and we got to talking and we took the kit out of the boxes and started test fitting. Well, long story short, the next day I took it to get color matched. Thank you, Erick, for convincing me it would look great—man he was right."

The Mode Parfume pieces don't depart too far from Honda's original intent, but a reshaped bumper with an integrated lip and a carbon fiber splitter update the front end. MP's EK style side skirts replace the rounded OEM pieces, an angular hatch wing reshapes the rear's appearance, and a pair of carbon mirrors were bolted in place. The same Desert Sage Metallic paint that the car was purchased with is in place, with the front getting a refresher to welcome the new front bumper.

In the years that Roger has improved upon the car in just about every way, he's completely revamped the suspension, including a switch to PCI spherical bushings throughout the car's rear, ASR sway bars, a traction bar, roll bar, and a custom R Fab shock tower bar. Front braking was addressed with Wilwood calipers and rotors, and GS-R calipers are used in the rear, also on Wilwood rotors.

Maintaining a very complete street car, Roger's interior is kept simple and tasteful with a set of Recaro SR4 Tomcat buckets replacing the original Si seats, and a Momo wheel relieving the factory wheel of duty. An S2000 cluster takes the analog gauges to a more modern digital status, and R Fab's custom pedals and shifter add appearance and driver feel.

Restomod Civic builds are all the rage, and Roger found a way to tie the past with the present in a way that's not overdone and in no way half-baked. It's a recipe that's been done time and time again, but it's the execution that makes his build stand out.
