The Short Version
- 4×100, confirmed on both the GTI-R grade page and the ordinary N14 Pulsar page.
- Factory wheel: 14×6J at +40 on 195/55R14. The ordinary 1.3-litre N14 runs 13×5J at +35 on 155SR13.
- So the GTI-R’s difference from a normal Pulsar is the wheel and tyre, not the bolt pattern. The whole N14 family shares 4×100.
- The hub bore is not merely absent — it is explicitly marked “under investigation” by both Japanese databases. We explain what that means below.
調査中
We had this car blocked in our backlog for one reason: we could not find a hub bore. Having now looked properly, we can tell you exactly why.
Both Japanese factory wheel databases print the same three-part line on every grade page — PCD, hole count, hub bore. On the RNN14 GTI-R page, the first two are filled in with 100 mm and four holes. The third reads 調査中: under investigation.
That is not a blank cell and it is not an oversight. It is the database explicitly saying it does not have the figure. The same marker appears on the ordinary N14 pages, and on the other database as well.
We then went looking for the usual fallback — a Japanese hub-ring manufacturer’s fitment table, which is often how these gaps get filled, because those companies have to know the number to sell the product. We found no hub-ring product listed for the RNN14 at all.
So there is no number to give you and no secondary figure to weigh against. This is a genuine gap in the public record, and we would rather publish that than print something plausible.
Factory Specification
| Model | Chassis | Period | Wheel | Tyre | PCD / Holes / Bore |
|---|---|---|---|---|---|
| Pulsar GTI-R | RNN14 | 1990.08–1995.01 | 14×6J +40 front and rear | 195/55R14 | 100 / 4 / under investigation |
| Pulsar 1.3 V1 (for comparison) | N14 | 1994.05–1995.01 | 13×5J +35 | 155SR13 | 100 / 4 / under investigation |
What to Do About It
Practically, the missing figure matters less than it sounds, for a specific reason: the bolt pattern is 4×100, which is one of the most common patterns in Japan, and the wheels people actually buy for this car are period Japanese 4×100 wheels that were designed for hubs in the 54 to 60 mm range.
Our advice is the same one we give for any car where the register is unpublished. Measure it. Take a wheel off, measure the diameter of the machined circular step the wheel seats on — not the outer edge of the hub flange, and not the hole in an aftermarket wheel you already own. Take two measurements at right angles and use the larger.
Send us that number with your chassis code and we will match wheels to it. We will also add it to this guide with credit, because evidently the databases are not going to.
Sizing
The GTI-R’s factory 14×6J at +40 is small by any standard, and the car is a 227 PS four-wheel-drive homologation special with a lot to put down. Almost everyone changes them.
The usual move is 15×7J or 16×7J in the +35 to +45 range. The GTI-R’s arches are wider than an ordinary Pulsar’s but not by a great deal, and the four-wheel-drive front end does not tolerate a big offset change well — going much below +30 puts the tyre into the arch liner at lock and changes scrub radius on a car whose steering already has plenty to say.
UK and Australian Cars
The GTI-R was sold in the UK and Australia as the Sunny GTI-R, and the differences from the JDM Pulsar were in the engine calibration — the export cars were mapped for lower-octane fuel, costing a handful of horsepower — and in the bumpers, modified to take European plates.
On the wheel side, an owners’ registry gives the export car the same 14×6JJ at +40 on 4×100. That is a community source rather than a homologation document, so treat it as good trade knowledge. It is consistent with the JDM figure and with the cars being otherwise identical.
Importing
The RNN14 ran from August 1990 to January 1995, so the entire production run is eligible for US import. It was never sold new in North America in any form, which is exactly why it is on so many want lists.
What We Could Not Verify
- Hub bore, front or rear. Both Japanese databases explicitly mark it “under investigation”, and no hub-ring vendor lists a product for this chassis.
- Whether UK and Australian Sunny GTI-R cars carry the identical hub, as opposed to the identical wheel. Sourced to an owners’ registry, not a factory document.
- Factory wheel data for GTI-R production years other than the grade page we opened.
