Custom Fabrication

A mainstay of DILYSI Motorsports is custom fabrication of racecar parts.  These can be done completely to your specs, or with additional input from us.  See some examples below.

Custom Intake Manifold  for Volkswagen

Fabricated to our customer's specs using factory runners coupled to a custom large volume plenum.  It accepts a larger throttle body from a later model Volkswagen.  The EGR Port was eliminated (it used to interrupt runner #2 before it was welded shut) to allow more consistent performance in all cylinders.  A vacuum ports for the brake booster was retained, but all other vacuum ports were eliminated.  The finish is a gloss white powder coat.  Actual numbers won't be divulged, but the dyno showed that the gains were significant.

Torque Suppression Device for Volkswagen

A completely bolt on Torque Suppression Device for an A1 Volkswagen.  It effectively triangulates the front motor mount, while still meeting the SCCA Solo2 Street Prepared Rules regarding such a device.  Since it limits the movement of the engine, it allows the car to put power down more effectively, as well as shift more predictably.  It is adjustable for preload.  The hardware retains it's natural finish, while the welded bracket is powder coated gloss black.  Click on thumbnails for larger pictures.

Turbocharger for 89 Civic Si

Here are various progress pictures of the development of a turbo system for an 89 Civic Si.  This build is for a dedicated autocross car, thus a wide power band is more useful than a high peak number.  With this in mind, the system is using low boost (4-6 psi) on top of high static compression.  Additionally, every component in the system was chosen to minimize lag, while maintaining affordability.  This includes a T25 Turbo, a log style manifold, a liquid intercooler, and short intake piping.
