Pointless thread that probably has no answer.

Ever wondered why both the GS-R and ITR were given the DC2 chassis code? The non-VTEC Integra coupes were given the code DC4, yet as far as I know there is no difference in the chassis between the DC4 and GS-R.

There is, however, a fairly substantial difference between the GS-R and ITR structures. Enough that I wonder why it did not get its own chassis code.

I've just always thought that the GS-R, LS, GS and RS should have had one code and the ITR should have gotten a different one, as those are different chassis.

Not that it matters at all.

 

I have always found that kind of odd. I figure they initially made it different to designate the vtec motor and then when the ITR came out they just threw that into the vtec category.

 

I think the chassis code refers to engine capacity as the ITR and GSR both have 1797cc engine whereas all the DC4's have 1834cc capacity, and in japan all DC1's no matter what the badge (ZX/ZXi/Ti/Xi etc ) all had 1597cc SOHC engines.

 

Hey there, I'm cross-posting this from another thread. I agree that the Type-R has several chassis differences over the GS-R, so I can't answer why Honda didn't assign the R a different code than the 3-door GS-R, but look at what those 4th thru 6th characters in the VIN designate.

Hope this helps



So, when talking about the ITR..

Japanese-built Honda Motor Company Ltd. Acura Division passenger vehicle, Integra 3-door with B18C5 engine, 2-door hatchback with 5-speed manual transmission, Type-R series

 

Hey, that is pretty interesting.

I also was not aware that there even was a DC1. I knew that Japan had some 1.6L Integras, but did not know that they also had a unique chassis code. That does further explain the logic behind the codes.

It also explains why the 2nd-generation GS-R had a different chassis code from the DA Integras.

I still wonder though why they use engine displacement in the chassis code. It seems to me (having, of course, never run a vehicle manufacturing company) that the chassis code should denote the chassis itself, not what's bolted into it.

This also brings up the question of why the hell they called the RSX a DC5. Surely the chassis has nothing at all to do with that of the DC2/4.

 

Or for that matter, why the 6th gen Civic, in Si form, was EM1 while the other 6th gen coupes were EJ6, EJ8, etc.. and the 7th gen Civic coupes were EM2.

 

I just learned something new. That is sort of counter intuitive.
