| The most popular models of the R31 today is first the 2 door coupe, next is the 4 door hard top, and the 4 door sedan takes last. The wagon is considered to be original in its own class, even though it is a part of the R31 series.
Compared to the other vehicles, there aren't much of these wagons left rolling around. Regardless, some hardcore enthusiasts still look for the station wagon style when purchasing an R31. The owner of this station wagon is indeed one of those hardcore enthusiasts; having to fall in love with the wagon at first sight he decided to purchase the vehicle right on the spot.
The R31 station wagon was released as the same year as the 4 door sedan in 1985. The wagon was released as a luxury vehicle and it came equipped with an RB20ET Passage GT turbo. There was also a standard CA18S equipped version called the 1800 Excel series in which there was much more available of. The wagon covered in today's story started off as a 1800 Excel base, which R31 House swapped in an RB25DET and a 5 speed manual transmission.
Mr. Shibata from R31 House states “this R31 wagon came with the CA18S which was practically very low in capability in regards to performance. The RB25 is a great candidate as cost per performance, and even R31s equipped with an RB20 should consider this swap.”
| The engine internals remains stock with a TD06-20G bolted right on. The owner of this vehicle likes to take the car up to the mountains so rather than aiming for peak power, the setup was targeted for response and quickness. A front mount intercooler was planted, along with a Trust surge tank and throttle body. The muffler is a custom made unit by Mr. Shibata. Tuned and regulated by Fcon Vpro, the vehicle makes 330 horsepower at 1.0 bar of boost.
For the exterior, it may look stock but looks can be deceiving especially to a non-car enthusiast's eyes. The front fascia was replaced with that from a R31 2 door coupe. The sharp and sporty exterior was achieved also with the R31 House original aero kit.
As a chassis, the R31 platform is relatively popular, but as a station wagon, many people might not consider this as a tuning base. The 2 door and 4 door hardtop models still take the cake as the most popular R31 series to modify and own.
