COMPATIBLE: (3.0L – VR30DDTT)

2023 – 2025 NISSAN Z RZ34

Introducing the Mishimoto 2023+ Nissan Z performance heat exchanger. Designed to unleash the full potential of your high-performance Z, our relentless pursuit of excellence has led us to develop a heat exchanger that perfectly fits the 2023+ Nissan Z and provides optimal cooling efficiency while enhancing overall performance.

A performance vehicle like the Nissan Z deserves a performance charge air cooling system, and this heat exchanger delivers. The 172 percent increase in core volume allows the Mishimoto heat exchanger to remove more heat, from more coolant, in less time. The result is outlet coolant temperatures 10 degrees cooler than stock in our rigorous heat soak testing. On top of that, our heat exchanger reduces pressure drop by 2 psi compared to the stock cooler. This reduction in restriction makes our cooler more efficient and puts less stress on components like the charge air cooling water pump.

But improved performance is nothing if it doesn’t last. This durable heat exchanger features high-quality aluminum end tanks that will outlast the stock plastic crimped end tanks and withstand countless heat cycles without failing. For added durability, our heat exchanger retains the stock rock guard to protect it from debris.

The Mishimoto 2023+ Nissan Z performance heat exchanger is a direct fit for your Z with no other modifications. And, to make installation even easier, we’ve strategically positioned an air bleed port that allows you to purge air from the system with the bumper on. So, whether you’re a seasoned enthusiast or a DIY novice, you can easily and confidently upgrade your Nissan Z.

Elevate your driving experience and unlock the true potential of your 2023+ Nissan Z with this Mishimoto performance heat exchanger. Like all our Nissan Z products, the Mishimoto 2023+ Nissan Z performance heat exchanger includes the Mishimoto Lifetime Warranty, ensuring peace of mind and complete satisfaction as long as you own your Z.

What makes a car so alluring? Sure retro-modern styling combined with a power-hungry powerplant draw you in, but what keeps you in the drivers seat? Consistency. Sports cars like the Z are intended for those with a lead foot and a need for speed, so keeping things consistently cool is imperative. Lets face it. Theres no worse torture to an enthusiast than having to feather the throttle on their high-strung sports car because of looming high temperatures. Nissan knows this, and while they did their best to set the Z up for intercooling success, the heat exchanger still needs an overhaul for what we enthusiasts have in store.

Air-to-water intercooling is how every teacher envisioned group projects. Instead of one person doing the work the whole group takes credit for, every member performs their role while playing to each others strengths and weaknesses to reach a common objective. In this group project, the intercoolers may get most of the credit, but the heat exchanger is really the one doing most of the work. For those unfamiliar with the specifics of an air-to-water intercooling system, basically, heat is transferred twice. First, the heat from the charged air is absorbed by the coolant passing through the intercoolers, and then that heat is dissipated once the coolant cycles through the heat exchanger. As the boost increases with tunes or bigger turbos, so does the heat, so upgrading the intercoolers is an essential means of managing intake air temperatures, but ensuring the heat is properly dissipated from the system entirely is a higher priority.

Air-to-Air vs. Air-to-Water Intercooling

By now, the VR30DDTT has already become a staple in Nissans performance lineup. Although their engineers might have updated the heat exchangers from the miniature units found on the Q50 and Q60, theres still room for improvement. Even with the upsized core, this design is still prone to heat soak during spirited drives or even just sitting in traffic on a hot day.

Coupled with the OEM designs hot-headed behavior is this radiators questionable durability. In typical OEM fashion, the stock unit equipped with the Z combines an aluminum core with plastic injection-molded end tanks. This construction provides the perfect balance between heat dissipation and inexpensive manufacturing that may increase Nissans bottom line but at the cost of snubbing the Zs potential. Plastic has come a long way over the years, but it still has its faults, especially when it comes to repeated heating cycles. Over time this plastic can break down, leading to leaks or even disintegrating connection points, and brittle inlets arent ideal for maintaining intake air temperatures.

Even though the cooling stack has ample access to fresh air, its still important to maximize the heat exchangers footprint.

The Q50 might have paved the way for the latest Z and even carried over a few components, but some things are not transferrable. For example, our first inclination was to bolt our Q50 performance heat exchanger to the front of the Z but remodeled front end didnt leave much room for our previous design. Instead, Nissan needed to pack a lot of cooling into the bow of the Z, which entailed a heat exchanger design that left space for the transmission cooler. So, we tasked our engineer, Ye, with applying that same performance in a new design bespoke to the Z.

Yes design process starts with a 3D scan of the Zs front end. Then, with the help of our Faro Design ScanArm, she can generate a scale digital replica of the vehicle. Within this virtual workspace, Ye can precisely devise an improved cooling method for the VR30s intercooling system even after the Z leaves our facility.

Here is the scan of the Zs front end with the stock heat exchanger highlighted in red. In this virtual workspace, you can see plenty of open real estate to expand our new design.This 3D model shows Yes proposed design within the confines of the Zs front end. As you can see, were planning to capitalize on the open space for optimal cooling performance.

When it comes to radiators, size matters, especially when it comes to core volume and the external fin surface area, and were adding to both. To put it simply, adding to the cores volume means that the heat exchanger can cool a larger quantity of fluid as the air passes through the fins. Likewise, the extended fin surface area only furthers a radiators cooling efficiency by spreading the cores volume over a larger surface. With our added height and width to our core design, we calculated a 140% bump in core volume and a 62% increase in fin surface area. By spreading this larger volume out over a greater area, this design is much more efficient at cooling the increased system fluid capacity.

While size is essential to the heat exchangers performance, the beauty of this design is more than skin-deep. For starters, to further optimize performance, were incorporating a louvered fin design on this heat exchanger. This fin design amplifies the heat dissipation effect by directing the air to flow through the core diagonally, with the extended contact extracting more heat from the coolant. Were also planning on a full-aluminum construction, mitigating the risk of deteriorating plastic entirely from the equation. Finally, to top things off, our design will also feature a removable inlet to simplify the installation process.

Consistency is key to the performance of any vehicle, especially one with the Zs reputation. Nissan might have pulled out all the stops to keep its VR30 powerplant cool, but the stock heat exchanger will have trouble keeping up with we enthusiasts demands. Make sure that you stay tuned to get the first look at our completed design coming soon.
