Engine & Transmission Builds

Serious power goals eventually come down to the engine and transmission themselves. HTP Motorsport builds and rebuilds engines and transmissions for performance and drivetrain upgrades, planning the powertrain as a whole rather than treating each component as a separate project.

This is a good fit if:

  • You're planning a build that goes beyond bolt-on upgrades into the engine or transmission itself.
  • An existing engine or transmission needs to be rebuilt rather than replaced.
  • You want the powertrain planned as a whole, not piecemeal.

Performance Tuning

Tuning is about matching a vehicle's calibration to what it's actually built to do. Whether your car is stock and looking for cleaner throttle response or running aftermarket forced induction and supporting hardware, HTP Motorsport tunes European and performance vehicles using in-house dyno time to verify results rather than guess at them.

Race Prep

Getting a car ready for the track is different from getting it ready for the street. HTP Motorsport prepares performance vehicles for track days and racing — suspension and alignment setup, brake and cooling system checks, and the fluid and safety inspections that matter once a car is actually being driven at the limit.

Performance Upgrades

Where tuning is calibration, upgrades are the hardware itself — the physical parts that change what a car is capable of. HTP Motorsport installs intake, exhaust, suspension, brake, and forced-induction components on European and performance vehicles, sequenced correctly so later tuning work has something solid to build on.
