AMS Performance - Nissan Z RZ34 VR30 Intercoolers

The factory intercooler system on the VR30DDTT engine leaves a lot of room for improvement. Starting by designing the AMS Heat Exchanger to expel excess heat in the system, our team knew as time went on the platform would advance to higher and higher power levels that would necessitate better cooling, which is why our AMS SNAILWORKS© Engineering Team went back to the drawing board to push the Nissan Z platform even further.

The AMS Performance Nissan Z VR30 Intercoolers completely rethink how VR30DDTT intercoolers can be designed. While nearly all aftermarket air-to-water intercooler cores feature a conventional cross-flow design, our engineers identified that a counter-flow system can allow for improvements in thermal efficiency due to the way they pair the coolest water with the coolest air, inside the core. The AMS Performance Nissan Z VR30 Intercoolers are properly engineered for maximum thermal transfer.

AMS Performance is an engineering company first. We have built our over 20 year reputation as a leading motorsports aftermarket component manufacturer by creating the highest performing parts through a focused approach to design. Where others in the industry settle for “good enough”, we strive for excellence. This design methodology allows us to include features not found in other kits on the market, including CAD designed billet 6061 T6 aluminum end tanks for improved fitment and aesthetics, and large CNC machined integrated barb fittings and high quality coolant hoses. Our team didn’t stop at improved aesthetics however, they were able to design an included line kit with 33% larger feed lines and 20% larger return lines over OEM. While others use tiny low quality fittings and low grade rubber hoses, the AMS Snailworks© Engineering Team have put together a system that uses the highest quality materials for years of trouble free operation.

For the foundation of the AMS Performance Nissan Z VR30 Intercoolers we chose large, motorsport quality, counter-flow cores. This high efficiency, custom specified core is much larger and dissipates heat quickly for maximum cooling. Through our larger design, added thermal transfer capability, and drastically increased coolant flow, your 3.0L VR30 twin turbocharged engine benefits from reduced intake air temperatures (IAT), boosting your power output.

By massively increasing the volume of the core and optimizing the thermal transferring surface area compared to OEM, you gain an extraordinary amount of added cooling efficiency. The AMS VR30 Intercooler cores are an astounding 70.4% larger than the factory intercooler cores. You gain increased thermal efficiency for the entire intercooler system by accommodating this additional heat transfer capability. Whether you live in a hot climate region, enjoy drag racing, or long high speed pulls on airstrips the AMS Performance Nissan Z VR30 Intercoolers will help keep your intake temps lower and maintain your Nissan Z’s maximum power output no matter the conditions.

One of the most important systems on the VR30DDTT engine is the Temperature Manifold Absolute Pressure (TMAP) sensor, and how it functions to inform the ECU’s compensation tables during engine operation. The location of this sensor on OEM and other aftermarket intercoolers places it in an isolated pocket of air inside the intercooler end tank. This leads to considerably delayed temperature readings, delaying important temperature related calibration strategies from taking effect. Our AMS SNAILWORKS© Engineering Team was able to optimize this sensor location to allow for more responsive and accurate temperature data. With accurate air temperature readings from the AMS Performance Nissan Z VR30 Intercoolers, your tuner can more precisely calibrate air temperature related safety trims and corrections to optimize power and improve safety in any condition.
