valve springs, and titanium retainers for high
RPM use. Port and polish cylinder heads to improve breathing,
and add an engine oil cooler to stabilize temperatures.
-
Professional
= Maximize engine performance and durability
for all-out racing - Install a stroker crankshaft constructed
of billet steel, titanium connecting rods, and lightweight forged
aluminum pistons for increased displacement and bottom-end reliability.

response and a dry sump oil system for cool, consistent lubrication
under any condition.
-
-
- Intake and Exhaust
- Increase power by improving both
your engine's intake and exhaust flow using components in matched
upgrade kits.
-
- Stock
= Install your vehicle's stock
intake and exhaust components.
-
Modified
= Install a high-flow replacement air filter element
and a performance, mandrel-bent cat-back exhaust system with
stainless steel sport muffler(s) for more efficient breathing.
-
Clubsport
= Replace stock intake system with high flow
cone air filter(s), stainless steel header(s), and track-only
catalytic converter bypass pipe(s).
-
Professional
= Install a carbon-fiber, pressurized cold
air intake system, resonance-tuned carbon-Kevlar intake manifold
and plenum, port-matched, lightweight titanium anti-reversion
header(s), and straight-through big-bore titanium racing exhaust
system.
-
-
- Fuel and Ignition
- Increase engine power by
upgrading fuel delivery and ignition systems using components in
matched upgrade kits.
-

-
- Stock
= Install your vehicle's stock
fuel and ignition system components.
-
Modified
= Install a custom ECU chip to improve power
through optimized fuelling and more aggressive ignition timing.
Add silicon-insulated ignition wires and platinum-tipped spark
plugs.
-
Clubsport
= Further increase fuel flow and promote optimal
spark for more power Install colder range spark plugs,
grounded ignition wires, capacitive-discharge coil pack, a high-flow
fuel pump , injectors, rails and filters, and a piggyback ECU
fuel and ignition timing management system.
-
Professional
= Maximize fuel delivery, spark energy, and
tenability of the engine-management system Install a racing
ignition system with individual coils for each cylinder, maximum
flow high-impedance fuel injectors, twin racing fuel pumps, foam-filled
racing fuel cell, and programmable stand alone fuel management
system. Optimize tuning for high-octane race fuel.
-
-
- Turbo
- Upgrade or add a turbocharger
system to your engine (offered as matched upgrade kits). Turbo systems
use wasted exhaust energy from the engine to spin a turbine,
which compresses air entering your engine. While turbochargers
dramatically increase your engine's power output, it can take
...
-
-
- Stock = Install your vehicle's stock
turbocharger system components.
- Modified
= Boost engine power moderately over its stock
level - Install ball-bearing sport turbocharger(s) (sized for
low lag, moderate boost) with an integral wastegate, cast iron
turbo manifold(s), and a manual boost controller.
-
Clubsport
= Boost engine power considerably over its stock
level, sacrificing some street drivability for better on-track
performance Install ceramic ball-bearing turbocharger(s)
(sized for moderate lag, high boost) with external wastegate,
ceramic-coated stainless steel turbo manifold(s) and flanged
down pipe(s), piston-type blow-off valve, water injection, and
electronic boost controller.
-
Professional
= Maximize engine power for all-out racing
at the expense of noticeable turbo lag Install large racing
turbo charger(s) (sized for high lag, maximum boost) with high-flow
external racing wastegate(s), Inconel turbo manifolds and flanged
down pipe, a high-flow piston-type blow-off valve, alcohol injection,
and an electronic boost controller.
-
-
- Supercharger
- Upgrade or add a supercharger
system to your engine (offered as matched upgrade kits). Powered
by a belt directly connected to the engine's crankshaft, a
supercharger compresses the air entering your engine. Because
they are powered directly by the crankshaft, the rob the engine of a
nominal ...
-
-
- Stock
= Install your vehicle's stock
supercharger system components.
-
Modified
= Boost engine power moderately above its stock
level - Install a positive displacement roots-type supercharger
(which produces low boost across the RPM range and a noticeable
improvement in low-end and mid-range torque).
-
Clubsport
= Boost engine power considerably above its
stock level - Install a larger positive displacement roots-type
supercharger (which produces moderate boost across the RPM range
and a noticeable improvement in low-end and mid-range torque),
and a custom-sized pulley, which spins the supercharger faster.
-
Professional
= There is no professional supercharger.
-
-
- Intercooler
- Increase forced-induction
efficiency, and thus powerful, by adding or upgrading an intercooler
(offered as matched upgrade kits). The intercooler cools the air
compressed by the turbocharger or supercharger. Note that this upgrade
cannot be added to a normally aspirated engine.
-
-
- Stock
= Install your vehicle's stock
intercooler(s).
-
Modified
= Increase power by lowering charge air temperatures
- Install a medium sized tube and fin core sport intercooler(s).
-
Clubsport
= Increase power by lowering charge air temperatures
- Install a larger, more efficient bar and plate core intercooler(s).
-
Professional
= Increase power by lowering charge air temperatures
Install a maximum-sized, high-flow bar and plate core
racing intercooler(s).
-
-
- Engine Swap
- Install the
engine from another car of the same manufacturer. Note when installing
another engine, the upgrades from your current engine are not
transfered.
