DSR Supercharged Integra type R

"Designed for demanding enthusiasts, the type R combines a lightweight design with high-performance components creating an Integra of unprecedented power and response." -Honda Motor Co. 1998

Off the showroom floor the Integra Type R will accelerate to 60mph in approximately 6.2 seconds and run the quarter mile in approximately 15.1 seconds. However, these outstanding straight line performance numbers only make up a small aspect of this machines abilities. Being on any type of racetrack is where most of the type R's performance stands out.

When the Integra Type R made its first debut in the United States in 1997-98, Championship White was the only exterior color offered. In 2000-01 the original color was discontinued and black and yellow became the only colors offered. After 2001, the Type R was never to be sold again in the US again. Options such as A/C (offered at standard in '00-01), sunroof, sound deadening and most all other creature comforts were left out. The Type R instead received a stronger frame, larger and more pronounced front and rear spoilers, close ratio gearing, lighter flywheel, stiffened clutch, high performance suspension, limited-slip differential, larger brakes with a 5-lug bolt pattern, light weight wheels, race inspired black seats with red stitching, carbon look interior components and a numbered plaque which revealed its limited edition status and model number.
The heart of the car is still the engine. This is where Honda did its homework and made it hard for consumers to make improvements. Seeking to build this the type R's engine Honda turned to its Formula 1 department. The end result was a 1.8L VTEC engine designed to rev up to 8400rpm and made 195hp. The handmade engine included a hand polished intake manifold and intake ports. To assist the new high-lift camshafts, lightweight intake valves and twin coil valve springs with an oval cross-section were added. To reduce the engines rotational weight and increase the rev-ability, lightweight connecting rods and low friction/ high compression pistons were used.
To finish the motor off, a high volume air intake and high flow exhaust system was added to give the type R motor that extra edge.
However, all this handbuilt technology came at a cost. Only a scarce 1341 white type R's came to the US for 1997-98. For 2000-01 the amount of yellow and black type R's remains unknown.

Of the 1341 white type R's which came to the US in 1998, #717 fell into the hands of DSR and this is where our story starts.

When Dynospot came into the life of type R #717 the owner Mike Marsey, was looking for a shop to fix problems several other shops caused. Installed on the car at that time was a Jackson Racing supercharger, a few basic intake and exhaust items and an array of "band-aid" devices, which in our eyes, didn't appear to work. From past testing, type R'a bone stock will typically put out 160-170whp with 117lb-ft of torque. A stock JR supercharger kit on a type R typically puts out 180whp and 130lb-ft torque. However, in this case, even with the supercharger and several bolt-on items it put out a jaw dropping 160whp and 116lb-ft torque! Almost less then a stock setup!!!
At that point, we realized the customers' decision to find a shop that could fix his problems and properly tune the car was a good idea. so we knew we had a long way to go to search out all the problems with the car. Over the next 3+ years Dynospot embarked on a mission to fix and tune this supercharged type R to make as much power as possible.
As of Dec 2002, this customers type R boasted an amazing 273whp (updated) with 190lb-ft of torque (updated).

Of course, this power wasn't fully achieved from just fixing problems and tuning the ECU. It was due to the selection of appropriate parts that would enhance the overall potential of the engine. The engine's setup currently includes a Jackson Racing supercharger with an custom boost upgrade pulley, cold air intake system, 3" free flow exhaust system with a 4-1 exhaust manifold, larger fuel injectors, stronger clutch, and a custom tuned proprietary DSR ECU. During early testing the DSR supercharged type R has achieved an amazing 12.5sec @ 114mph (updated) in the quarter mile with little traction which gives new 996 turbo Porsches and Vipers a run for their money. However, DSR is still not finished with this monster. Were still in the process of doing additional dyno testing to extract even more power out of this car, as well as were are still in the process of doing more drag and track testing.

More information on the car's new direction and winning setup will be added soon!
