CSF Racing 2-Row 42mm Billet Ultra High Performance Aluminium Radiator - Nissan Skyline R32 GTS/GT-R (RB20/RB26)

The Nissan R32 Skyline is a true JDM legend. From GTS to GT-R, the love for this chassis runs deep. Here in the states it is still one of the most popular JDM imports. Import companies like TopRank have been helping enthusiasts acquire these dream vehicles for years. Now they have teamed up with CSF to help bring a truly special product to the market. Introducing the Full Billet High-Performance Aluminum Radiator for the Nissan R32 Skyline.

CSF and TopRank Partnership

TopRank Vehicle Importers is one of the largest importers of JDM specialty vehicles in the USA. They’ve become the go to company for anyone looking for a high quality and excellent condition Skyline. As the local branch of TopRank Global, an international export dealer in Japan, they have access to the best possible selection of classic JDM legends. Needless to say, TopRank has a lot of experience with the R32 Skyline and specifically the R32 GT-R. You’ve no doubt seen some of the cars they’ve imported featured on social media like the Built by Legends Mine’s R32 GT-R or the first R33 NISMO 400R in the USA.

Why an Upgraded Radiator?

Many of the vehicles that TopRank imports are sent over to the states with most of the original parts. This includes a 25+ year old plastic radiator. TopRank has many upgrades and services they offer for their vehicles that customers can elect to do before purchasing. One of the items they had been looking for was a replacement radiator they could feel confident about selling and installing on the Skyline models. They tested out all of the reputable aftermarket options and could not find one they felt confident in endorsing. CSF has had a good relationship with the team at TopRank for years. So naturally when this product idea came about, CSF was their first choice to work with.

Combining their in-depth market and technical knowledge of the R32 and CSF’s decades of experience designing and manufacturing high performance cooling products resulted in the ultimate R32 radiator. You won’t find a higher quality or better performance system anywhere else.

Design & Engineering

CSF set out to develop a premium radiator that would offer ultimate performance cooling while being built to last a lifetime. Since the R32 is a valuable collector’s car, it makes sense to use the highest quality parts when restoring or modifying them. With full CNC machined billet aluminum end tanks TIG welded by hand to the high grade aluminum core, this radiator performs even better than it looks.

OEM vs CSF

The 2-Row 42mm core greatly not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF’s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. More cooling rows also improve the overall efficiency of the radiator. More cooling tubes means more surface area for the coolant’s heat to dissipate from.

Each end tank is CNC machined billet aluminum giving them incredible strength and durability. CNC machining offers incredible precision and uniformity. The results are perfectly produced end tanks that perfectly match up with the ends of the 42 mm core. Hand TIG welding joins the tanks to the core creating the strongest radiator on the market for the R32 Skyline.

Each radiator includes a 1.4 bar high pressure cap with an embossed CSF logo. High pressure radiator caps raise the boiling point of coolant. This helps protect the system from boiling over at higher operating temperatures. While the radiator is designed to keep the system from reaching such temperatures, it is always good to have extra protection for situations where the coolant gets too hot.

Track Tested

TopRank employs many car enthusiasts. One of those is their National Sales Director Brian Jannusch. Brian is avid motorsports junky that tracks his own R32 Skyline GT-R. You may have seen it if you frequent any of the tracks in Southern California.

His GT-R has had the CSF x TopRank Billet Radiator installed for a few months now and has seen several track days. The car has been pushed hard at events like Nissan Challenge and driven at tracks like Button Willow and Laguna Seca. Brain has given CSF nothing but positive feedback on the cars cooling performance and how well it has held up to long hot days of racing.
