4in 5in gauge cluster difference

Hey guys

quick one, differenct clusters sometimes are advertised and 4inch or 5inch versions. What does this refer to? I know the gearboxes come in 16in and 17 in which refers to the wheel size from factory but what does the cluster in refer to?

thabks.

Good question. Where exactly are these being advertised as "4inch" or "5inch" - is that being translated from Japanese? My guess is that this is referring to the subtle changes over the course of the FD3S production life.

FD3S - Type 1 - 12/91-09/94
FD3S - Type 2 - 09/94-03/95
FD3S - Type 3 - 09/94-01/96
FD3S - Type 4 - 01/96-12/98
FD3S - Type 5 - 01/99-09/00
FD3S - Type 6 - 10/00-08/02

Specifically referring to clusters - the visual cues between 4 and 5 are; the tach now has "0" at the 6 o'clock position, a boost gauge is in place of the oil pressure gauge and all the font has been updated. Oh, and the cluster lights up green as opposed to orange.

Hey thanks for the response

bidjdm and yahoo auction Japan, they always seem to have this 'inch' number in description. I know the clusters over the years had subtle differences but the thing is which made me ask the question is there seems to be more changes to the clusters than the inch numbers they use to describe the clocks.

i refer to my example of the gearboxes, the inch in their description refers to the size rim the gearbox should be used with (16in or 17in) maybe this has something to do with thwith ratios or the way sensors read revolutions etc.

so I assume the gauges have to refer to the size of something, why would they use this to describe changes in the lighting or gauge layout, surely they will use the year or zenki/chunk/kouki to describe the changes?

Nope. Not a size thing. I know exactly what you're talking about - it's an error of translation.

Sometimes it's "Ver", sometimes it's "Type", sometimes it's "in". You'll also see "early" and "late" references.

I promise you, the only real difference between clusters, besides the aforementioned changes (and of course, white face, black face, spirit-r, etc) is auto vs manual.

Yep, all clusters that I've ever seen will plug in and work. If it's a later cluster with a boost gauge you have to do some extra wiring, and you can also modify the cluster to read MPH and calibrate it (search, I've got posts on these topics).

I agree, I think you're just seeing a translation funny. Also remember Japan uses the metric system, most anything measurement wise will be in millimeters.
