HKS R-Type Intercooler Skyline GT-R R32 R33 R34

The HKS R-Type Intercooler Skyline GT-R kit, manufacturer part number 13001-AN007, is a high-performance charge-air cooling upgrade for RB26DETT-powered Nissan Skyline GT-R models. HKS lists this intercooler for the BNR32 R32 GT-R, BCNR33 R33 GT-R and BNR34 R34 GT-R, making it an excellent option for enthusiasts upgrading one of Nissan’s most recognised performance platforms.

Featuring a substantial 600 × 300.5 × 103 mm HKS R-Type intercooler core, the kit is designed to improve charge-air cooling while maintaining efficient airflow through the intercooler. It occupies the factory intercooler position and is intended as a vehicle-specific performance upgrade rather than a universal intercooler requiring a completely custom installation.

For modified road cars, fast-road builds and performance-focused Skyline GT-Rs, the HKS R-Type Intercooler Skyline GT-R provides a genuine HKS solution developed specifically around the RB26DETT platform.

Why Upgrade Your Nissan Skyline GT-R Intercooler?

Turbochargers compress the air entering an engine. As that air is compressed, its temperature rises. The intercooler removes heat from the compressed intake charge before the air enters the engine.

Reducing intake-air temperature can help provide a denser charge and more consistent operating conditions, particularly when the engine is working hard or repeatedly operating under boost.

This becomes increasingly relevant when a Skyline GT-R has been upgraded with modifications such as:

• increased boost pressure;
• replacement or upgraded turbochargers;
• ECU calibration;
• intake improvements;
• exhaust upgrades;
• fuel-system modifications;
• other supporting engine upgrades.

An ageing original intercooler can also become less appropriate as power and airflow requirements increase.

The HKS R-Type Intercooler Skyline GT-R is therefore particularly suited to owners who want to improve the intercooling system while retaining a chassis-specific installation.

HKS R-Type Intercooler Skyline GT-R Performance Benefits

The HKS R-Type intercooler range is designed around the need to balance effective cooling with low airflow restriction.

Simply installing a physically large intercooler does not automatically produce an ideal result. Charge air must pass efficiently through the core while heat is transferred away to the outside airflow.

Improved Charge-Air Cooling

The large 600 × 300.5 × 103 mm core provides increased heat-exchange capacity compared with the standard factory intercooler arrangement.

Effective charge-air cooling becomes particularly valuable during repeated acceleration or sustained boost, where temperatures can progressively increase.

For modified RB26DETT engines, improved intercooling forms an important part of a properly considered performance package.

Reduced Pressure Loss

HKS uses a triangular straight inner-fin design within its R-Type intercooler construction.

The internal fin structure is designed to promote efficient airflow through the core while helping to control pressure loss.

Reducing unnecessary airflow restriction is important because excessive pressure loss between the turbochargers and engine can negatively affect the overall efficiency of the forced-induction system.

Improved Heat Dissipation

The exterior of the HKS R-Type core uses triangular louvred outer fins designed to improve heat transfer from the intercooler to the air passing through the front of the vehicle.

This combination of internal airflow management and external heat dissipation is central to HKS’s R-Type intercooler design.

Performance-Focused HKS R-Type Construction

The HKS R-Type Intercooler Skyline GT-R uses the manufacturer’s performance-oriented R-Type core technology.

HKS positions the R-Type series towards higher-performance turbocharged vehicles, including cars using upgraded turbocharger configurations.

The verified core dimensions for part number 13001-AN007 are:

600 × 300.5 × 103 mm

The kit is designed for the original front intercooler location on compatible Skyline GT-R models.

Rather than being a generic intercooler that requires custom mounting and pipe routing, 13001-AN007 is specifically listed by HKS for the RB26DETT-powered GT-R chassis covered below.

Nissan Skyline GT-R Vehicle Compatibility

HKS specifies part number 13001-AN007 for three generations of Nissan Skyline GT-R:

Nissan Skyline R32 GT-R — BNR32

Compatible with BNR32 Skyline GT-R models equipped with the 2.6-litre twin-turbo RB26DETT engine.

HKS lists the application from approximately August 1989 through December 1994.

For customers in Britain, it is important to understand that the R32 GT-R was not originally an official UK-market model. R32 GT-Rs currently used in the UK are predominantly Japanese-market imports.

This does not affect the manufacturer’s mechanical application of the intercooler to the BNR32 chassis.

Nissan Skyline R33 GT-R — BCNR33

Compatible with BCNR33 Skyline GT-R models using the RB26DETT engine.

HKS lists this application from approximately January 1995 through December 1998.

The BCNR33 should not be confused with other R33 Skyline models using different engines, drivetrains or chassis configurations.

Nissan Skyline R34 GT-R — BNR34

Compatible with BNR34 Skyline GT-R models equipped with the RB26DETT engine.

HKS lists the BNR34 application from approximately January 1999 through August 2002.

The kit should not be assumed to fit non-GT-R R34 Skyline models simply because they share the Skyline name.

RB26DETT Performance Applications

The legendary RB26DETT 2.6-litre twin-turbo engine responds to a wide range of modifications, but increasing airflow and boost also increases demands on supporting systems.

The intercooler is only one component within that system.

Owners planning higher-output builds should consider the intercooler alongside:

• turbocharger specification;
• boost pressure;
• air intake system;
• intercooler piping;
• fuelling;
• ECU calibration;
• radiator efficiency;
• oil cooling;
• exhaust flow;
• engine condition.

For modified road and performance builds, the HKS R-Type Intercooler Skyline GT-R provides a vehicle-specific alternative to universal intercooler installations.

Performance results will ultimately depend on the complete vehicle specification and calibration rather than the intercooler alone.

Road and Track Applications

Although the HKS R-Type range is performance-focused and suitable for demanding applications, the HKS R-Type Intercooler Skyline GT-R is not limited to dedicated track cars.

It can also be appropriate for road-driven Skyline GT-Rs where owners want improved intercooling as part of a correctly engineered upgrade package.

Examples may include:

• tuned road cars;
• fast-road Skyline GT-R builds;
• occasional track-day cars;
• upgraded turbo applications;
• higher-boost RB26DETT builds;
• restored or upgraded GT-Rs replacing older intercooler components.

Customers should avoid selecting an intercooler purely on the basis of physical size. The entire engine, turbocharger and cooling configuration needs to work together.

Factory-Position Installation

HKS 13001-AN007 installs in the factory intercooler position.

The installation procedure involves removal of front bumper-related components and the original intercooler before the HKS core and supplied mounting hardware are installed.

According to the HKS installation information, the vehicle’s original intercooler hoses are used to connect to the replacement intercooler.

This is important because 13001-AN007 should not be advertised as a complete replacement intercooler piping kit.

If your car already has aftermarket piping, custom turbocharger plumbing or a non-standard front-end configuration, compatibility should be checked before ordering.

Important BNR32 and BCNR33 Installation Notes

Owners of BNR32 R32 GT-R and BCNR33 R33 GT-R models should be aware of several model-specific considerations.

HKS specifies that factory optional fog lamps cannot be retained with this intercooler on relevant BNR32 and BCNR33 applications.

The installation documentation also identifies a requirement to modify or remove part of the mounting boss on the factory recirculation tube where necessary to prevent interference with the intercooler.

These details make it especially important to inspect the vehicle’s current configuration before installation.

Older Skyline GT-Rs may have accumulated numerous aftermarket modifications throughout their lifetime, so two outwardly similar cars may no longer have identical intercooler, bumper or pipework arrangements.

Compatibility with Modified Skyline GT-Rs

Before purchasing the HKS R-Type Intercooler Skyline GT-R, owners of modified vehicles should check whether previous upgrades affect the installation.

Particular attention should be paid to cars fitted with:

• aftermarket front bumpers;
• custom intercooler piping;
• replacement turbochargers;
• non-standard recirculation plumbing;
• relocated filters or reservoirs;
• additional oil coolers;
• modified radiator installations;
• custom air-conditioning components;
• previous front-end structural modifications.

The fact that a vehicle is a BNR32, BCNR33 or BNR34 does not guarantee that every existing aftermarket component will work with the HKS installation.

If you are unsure, compare the current vehicle configuration with the HKS installation requirements before ordering.

Professional Installation Recommended

Installation involves front-end disassembly, intercooler mounting and model-specific checks.

Professional installation by a workshop familiar with modified Japanese performance cars is therefore recommended.

After installation, all hoses, clamps, mounts and surrounding components should be checked carefully.

The intake system should also be inspected for leaks before the vehicle is subjected to significant boost.

For substantially modified RB26DETT vehicles, the engine-management calibration and overall cooling package should also be reviewed where appropriate.

Why Choose HKS for Your Skyline GT-R?
