What do the model numbers mean?

[geschman]

I was wondering what the differences are between the HR33, ER33 & ECR33 (specifically for the R33 GTS25, but for all types would be handy to know also). Is there any physical change in body shape?

Also, did the R33 GTS rb25de come with an LSD? Is there any way of telling from the firewall plate?

Thanks

I believe it's a designation of the engine/driveline type...

ER33 - 2.5L N/A

ECR33 - 2.5L Turbo

HR33 - 2.0L N/A

ENR33 - 2.5L N/A 4WD

BCNR33- GTR

Ns2500, i have a non turbo ECR33. Whats that mean?

[Guest neoGT-25]

anyone know what the R34 GT is?

is it still just, ER34?

[NS2500]

NA_R33, I have no idea!

Unless someone's put an NA engine in a turbo body? I got those details off some site on the net a while back - so I don't know how accurate it is.

haha, i spose that is more than a possibilty, im the first australian owner of my car so i know no history of it prior to that, but the guy that put the alarm in said it had the turbo wiring loom so i spose its a possibilty?? is there neway to tell?

[NA_R33]

i mean it does have the non turbo speedo, but it also has hicas and no abs, though i have never felt nor seen the hicas working, is there nething unique that only the turbo would have? also the air box is missing a bracket.... though it has non turbo brakes. Its got me thinking though.

Easiest way to check would be to look at the wheel stud pattern

4 = non turbo from factory, 5 = once was turbo

Im pretty sure no one would bother to change to a 4 from a 5 when taking out a turbo

Other way round yes

[NA_R33]

yeah its the 4 stud pattern but it has hicas that i have never seen or felt working. is there neway to tell if the hicas is working?

[nismoman18]

hicas turns the rear wheels 1 degree only, u cant feel it working mate. But the light should light up when u start the car, and look under the car where the rear drive setup is there should be a a motor that is the sterring motor

[NA_R33]

yeah all that is there, just never really sure if its worked or not, the light comes on when i start the car up.

hehe have you seen what HICAS does to a kakimoto widebody? it turns the wheel like 2 degrees, which, coupled with the 316 wheel size make it scrape along the guards... so much so that you gotta take hicas out on them or you can't drive it.
