R Series Front Mount Intercooler System


"GTR Fired and APS Hired.

The APS engineered 200SX is one of the most exhilarating street cars I have ever driven".

The APS R Series front mount intercooler has quickly become the benchmark for all front mount intercooler systems. Extremely high flow rates, massive temperature extraction and excellent resistance to heat soak.

And now the APS R Series front mount intercooler system has been certified for the S15 200SX.

In the case of intercooling, where bigger is better, APS shoehorned the largest intercooler core possible into the 200SX for maximum cooling capacity and engine performance. With a core size of 595 mm x 300 mm x 63 mm and enormous total intercooler core volume of 11,245 cm3 that's nearly 3.7 times the size of the standard intercooler - and along with the APS intercooler core being of internally finned construction it offers significantly enhanced flow and heat extraction performance than the standard intercooler.

But there's more to intercooling than size alone. Fully engineered cast aluminium end tanks ensure optimum charge air distribution throughout the entire cooling core for maximum cooling and to minimize pressure drop.

To achieve the highest power levels and excellent throttle response, APS has engineered the shortest possible route to and from the intercooler core. Unlike other designs that utilize the standard intercooler ducting route, the R Series intercooler system routes the hot charge air directly from the turbocharger on the left hand side of the engine bay, cools the air through the intercooler and then directs the chilled air directly into the inlet tract on the right hand side of the engine. Whilst this fmic detail crossflow design is technically demanding to design and manufacture, we at APS are not willing to compromise intercooler or engine performance.

An intercooler drops the charge air temperature which enhances the combustion of the air/fuel mixtures. This more complete combustion of air fuel mixtures produces higher engine power.

Intercooler performance can be measured by how much energy (temperature) the intercooler can remove from the inlet charge air and how low a pressure drop can be achieved through the entire system. It is important to consider the entire intercooler system and not simply the intercooler core itself. 

The chart shows turbocharger air temperatures of over 135 deg C (measured in the compressor cover) are cooled to 35 deg C at the inlet manifold (a massive 100 deg C drop in air temperature) under extremely arduous conditions. These are outstanding performance results. 

Also outstanding was the minimal pressure drop across the entire intercooler system. At 7,000 rpm with the pressure measured at the turbo and again at the inlet manifold resulted in just over 2 psi drop in inlet charge pressure.
