N1's Vs. 2530's

[No one]

hey guys,

just wondering about my future terb upgrade from the ceramics

im aiming for a tough streeter with the ocasional drag

ive got many recommendations to get 2530s but everyone who has the n1's swears by them...

whats your opinions?

[Guest Mashrock]

there are lots of differences between the n1's over all models and lots of difference between the few you get on r34.

from memory only one set is slightly larger than 2530's

but the 2530's are good when matched with cams etc.

[R31Nismoid]

Yep..

Which N1 turbos are you talking about?

R34 N1's are superb.

Other models from what ive seen on here are not so good.

[No one]

ha yeah sorry talking bout the 34 n1's

they seem to make pretty good power

[R31Nismoid]

they are pretty good turbos

search the forum, they have been covered extensively

HKS 2530:

TURBINE:

Inducer = 53.8 mm

Exducer = 47.0 mm

Trim = 76

A/R = 0.64

COMPRESSOR:

Trim = 63

Inducer = 47.7

Exducer = 60.1

A/R = 0.60

R34 N1's

TURBINE:

Inducer = 53.85 mm

Exducer = 42.4 mm

Trim = 62

A/R = 0.64

COMPRESSOR:

Trim = 55

Inducer = 44.57

Exducer = 60.1

A/R = 0.60

HKS GT-SS

TURBINE:

Inducer = 53.85 mm

Exducer = 42.4 mm

Trim = 62

A/R = 0.64

COMPRESSOR:

Trim = 56

Inducer = 44.46

Exducer = 59.41

A/R = 0.42

Edit: I have my suspicions that some of the A/R numbers are off. It looks to me for all the world like the R34 N1s were the base for the GT-SS, although someone else will have to comment as to whether they use the same catridge.

[Busky2k]

Going by those specs, the HKS 2530s are a fair bit bigger (bigger trim comp/turbine).

[R31Nismoid]

Yep

34N1's sit between GT-SS and 2530

[Crimmo]

I have just upgraded to 2530s and so far im very impressed, still waiting on a tune though to see the full potential. Possibly tuning this week so i will leave a post when i get it done

Hey No one

I recently bought a pair of Garrett GT2860R - 707160-5 and i'm happy. Lots of power on tap and very drivable.

My current RB is getting a bit long in the tooth for big boost and HP, but i'm still having lots of fun. Had some adjustable cam gears fitted as well as the usual bolt on mods

TURBINE:

Wheel dia. = 53.8 mm

Trim = 76

A/R = 0.64

COMPRESSOR:

Trim = 62

Inducer = 47.2

Exducer = 60.

A/R = 0.60

Yep

34N1's sit between GT-SS and 2530

Well if the A/Rs are incorrect, the GT-SSs are basically R34 N1s, at least spec wise. I -- and I'm sure most people -- have also heard the cliams of different exhaust housings on some revisions too.

If you want the occasional drag, then go the 2530's.

Hey No one,

sorry i'm a million miles from my R at the mo, so i cant post the sheets. Check out turbobygarrett.com and you can see the maps, Mine is making 406hp at the back wheels, I picked up 70rwhp on a 17 year old engine...fuel system running out of puff now. Every combo is different and so is the tune up.

Find a good tuner and ask to see some dyno sheets.

From my research, it looks to me as Lucien suggested: That the R34N1 are more or less the same spec as the HKS GT-SS.

Now remembering that both of the above are based on a Garrett Turbo,

The version of Garrett GT2860r that I bought is the "-7", and I got this because it had more or less the same specs as the GT-SS.

I've recently gone back to the Garrett Website and now find that they have actually mentioned that these are indeed the "OEM on Nissan RB26DETT used in Skyline R34 GTR N-1..."

You can see it here:

Read the little blurb on the left...

...and yes - they are an excellent turbo I think.
