ER34

Nissan Skyline R34 import check

ER34 is the factory model code for the Nissan Skyline R34, built for the Japanese market from 1998 to 2001. Every genuine car has a chassis (frame) number that starts with ER34-. That number is the one thing that links its Japanese history to its UK records.

From our own model library. UK records sometimes drop the hyphen or the leading zeros of the serial; our check allows for that.

Is it a genuine ER34?

ER34 covers the non-GT-R R34 Skylines. A car advertised as a GT-R with an ER34 chassis is a lookalike.

Known problems to check on a ER34

  • Rust in the rear arches
  • Turbo oil seals and boost leaks
  • Often modified: ask for a list of changes

These are common issues for the model, not facts about any particular car. Ask the seller about each one.

Kilometres, miles and the first UK MOT

A ER34 sold new in Japan has a speedometer in kilometres. When it is imported, the speedometer is either converted to miles or left in km, and the first UK MOT should record whichever the dial shows. Mistakes here are common, and they’re where mileage problems hide.

We put the Japanese auction mileage and every UK MOT reading on one timeline and check the crossing: whether the readings agree after converting, whether the km figure was written down as miles, and whether the first UK reading is lower than the car had already done in Japan. See an illustrative example.

Questions

What is the chassis code for the Nissan Skyline R34?

ER34. A Japanese-market Nissan Skyline R34 has a frame number that starts with ER34, then a hyphen and a serial number. You’ll find it on the V5C and on a plate in the engine bay.

Which years was the ER34 built?

From 1998 to 2001, with the RB25DET NEO (2498 cc turbo petrol) or RB25DE NEO (2498 cc naturally aspirated petrol) engines and RWD layout.

What should I check when buying a ER34?

Rust in the rear arches. Turbo oil seals and boost leaks. Often modified: ask for a list of changes. Also check that the Japanese auction mileage lines up with the first UK MOT, because km and miles are easily mixed up.
