Remember this EP3 that was here over the summer for the JDM 5 lug conversion? Well it’s back to complete the other part of the JDM-ness, that’s right, the K20A and all it’s glory.
Preparing of the JDM K20A.
Currently sitting somewhere outback in the dump.
Buddy club sports shifter box.
Buddy club header.
Hasport rear engine mount, again… highly encouraged with the used of a race header.
Buddy club spec 3 exhaust system, sounds just like the old DC5 🙂
As the car sits today, below is a shot taken from 2 years ago.
What once felt awful in braking, cornering and driving in a straight line… yes, apparently driving in a straight line can be terrible experience, now feels jolly smooth and adaptive. Now that the footwork with this EP3 is done, what’s next? Will it be the appearance or power unit?
It feels like forever since we’ve done one of these projects. Glad to see there is still one or two local fellows out there with interest.
What we have here is a JDM DC5 5 lug conversion that includes calipers, rotors, knuckles, control arms, trailing arms and sensors. The front knuckles were taken from the parted out DC5 track car, so bonus goodies include once replaced complete hubs, extended studs and J’s Racing roll center adjusters. Also from the parted out track car, Swift front and rear sway bars are to be installed.
The front lower control arms received our regular treatment of SuperPro polyurethane bushings. This is a must for the DC5 and EP3 platform, these cars suffer from lack of castor.
Much is to be gained from this affordable upgrade;
• Constant steering geometry
• Better on road handling and control
• Traction control, more responsive steering
• Longer service life of suspension parts
• Increased tire life
• Extra off road stability
• Alignment correction and stability
TEIN Super Street coilovers will be used on this EP3;
TEIN Super Street damper kit was designed for drivers seeking improved handling on the street and at the track. A shortened shell case is utilized to allow the most piston stroke possible, which allows for a better ride at lowered ride heights, and increased grip at the track. Great for daily driving and occasion track use, whether it be at the drag strip, local circuit, or Auto-X course. Includes both ride height and damping force adjustment to allow the driver to dial in the suspension for various surface conditions.
The day has finally come where I part ways with the Exedy Stage 2 clutch. Ideal for every day track use and NOT every day use! The combination of the insane weight and how it is either fully engaged or disengaged made it easy to say goodbye. An Exedy Stage 1 and flywheel would be used this time around. A Stage 1 would be good enough for the two to three times that I would track a year, in return I gain 362 days of driving enjoyment. With the transmission separated, old clutch and flywheel out, it is always a good idea to replace the clutch fork and pivot ball. Looking forward to driving again.
Notes:
EXEDY organic racing clutches only use premium friction materials that are resistant to slippage and burst. Increased clamp loads give the necessary capacity to handle modified engines. This is the preferred clutch for street and light horsepower track use. Driveability is similar to the stock clutch. Pedal efforts will be slightly higher because of the higher clamp loads. All of our clutch discs have spring center dampers to reduce drivetrain shock.
EXEDY Racing Flywheels are made from solid one piece billet chromoly steel forgings. They are specifically designed to reduce weight and inertia for better engine response.
Most incorporate special design features to enhance air flow to improve the cooling of the clutch. The ring gear teeth are milled onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and have the possibility of separating from the flywheel.
