No luck ?

[Beer Baron]

what is the comp A/R?

and what do you mean 'identify'? it sounds like you have all the details there.

I have no ideas but that's all the details i've been given to.

[Beer Baron]

get them to have a look inside the compressor outlet and tell you the A/R.

but what else do you need to know? there isn't much left...

have a look at the exhaust hosing, is it cast with a seperator between the wastegate outlet and turbine outlet?

Hi mate

It said M24 on it.

I guessed what i really like to find out is that is this a real R34 N1 with the bigger 64 exhaust housing or wheel but not the smaller version 60mm or something like that base on what i've read recently on the forum.

Thanks mate

I think that make a lot of sense now, we really should have a sticker thread with proper guide to N1 turbos.

that is not quite accurate as i have seen R34 N1s with my own eyes that are: BB, .64 exhaust, .48 comp cover. which would put them very close in spec to a GT-SS, where as the other 34 N1s i have seen were: BB, .64 exhaust .60 comp cover which puts them very close to a 2530.

you need to look inside the compressor outlet, the comp A/R number is stamped inside it.

EDIT: of course if it has .64 stamped on the rear housing then it's A/R is 0.64...

Fair enough, that is very interesting to know. What about the stupid Garrett M24 stamp on the front comp?

[The Dan]

You guys are barking totally up the wrong tree...those part numbers are N1's. They are the smaller in the GT2860R range which is standard fitment on the R34 GTR N1.

[The Dan]

Cop this!

PN 14411-AA403 is an R34 GTR Vspec II turbo fitted from November 2000

The original R34 GTR N1 turbo has the PN 14411-AA401 (January 1999 to October 1999) and the -AA403 is listed as a direct replacement (there was also an 'in between' -AA402)

[West]

Thank you very much guy, all your input are very help full and very interesting indeed.

[Guest Mashrock]

so which part number is the larger sized n1's

there has always been a good unknown about this question.

as it seems to have many variables

[West]

I dont know if NISSAN AUST is willing to help or not but i'll try to get something out of them.
