The ZD30 has always been highly strung from the factory with rich air fuel ratios and relatively low boost they exhibit very high EGT – only turbo I’ve seen with a glowing turbine housing on the dyno. Once pushed a little harder the top mount design isn’t effective. Replacement top mounted designs aren’t a lot better and we’ve heard of lots of extra constant induction noise with the top mount intercooler. Our front mount is the solution to this as the drop in inlet air temperatures is significant resulting in much lower EGT and improved performance and noticeable economy improvements.

The ZD30 kit will feature 2 1/2" stainless pipework to and from the intercooler with the stainless necking down to 2” to roll over 180deg and line up with the turbo outlet. This means no elbows coming off the turbo getting blasted with a constant flow of hot air. Our silicon joiner here now has an oil resistant coating. Piping on turbo side briefly goes through the wheel arch but is in stainless so is very unlikely to get damaged. The inlet side piping is also 2.5” stainless and has a joiner in the middle. A port is located on the pipe, before intake for connection to the MAP sensor.

The TD42 has long been a favourite and with the appropriate mods, can be a solid performer. Our front mounted intercooler will maintain cold day driving performance. We also run through the very front of the passenger side wheel arch area and into the engine bay. Connection to the turbo can be fun as there are many different turbo setups and orientations people run. We can supply an adapter to bold to the factory turbo outlet. The intake side has three parts with the top one being an intake adapter that bolts to the manifold. This adapter has a 1/8”NPT port with brass barb for a boost source.Patrol Series 1 from 1997 to April 2000 - PDI kit suitable for all Nissan diesel engines.

Auto Transmission Cooler Options

If you have an auto then by selection the auto option we will supply the standard kit with one for he best transmission coolers on the market (rated at 45,000BTU) and brackets that bolt to the intercooler with a series of holes that allow it to be located at three different heights. The lowest height places it down so only partially covering the bottom of the intercooler.

If you choose to use the original (factory) transmission cooler then you will need to fabricate some brackets and we recommend placing it on the passenger side in front of the hot side of the intercooler. This means the intercooler still has a really good chance to cool the intake air from air heat extracted from the transmission.

Thermo fan mounting

Following from above for auto with factory transmission cooler or if running a manual gearbox, this gives room to place the thermo fan on the drivers side which means any air pushed through may add to intercooler efficiency, but it means that the cooler side of the intercooler will allow cooler air to pass through and help with air conditioner consdenser function. Our intercooler has 2 lugs on the top and 2 lugs on the bottom to Thermo fan mounting easier. If running aftermarket thermofans we highly recommend SPAL fans from Italy.
