INFO: R32/33 GTR N1 Turbos and upgrading for a norml GTR??

[OohArrGTR]

Hey All, i just tried to do some searching but with no luck.. Can someone with abit of knowledge help us out... i have come across of some n1 turbos for sale to upgrade into my GTR32. mine got standard everything besides front pipes and exhuast..

What are the advantages in upgrading with these turbos?

Hp capability ?

what 1/4 times possible with small mods?

Turbo stats?

good prices?

disadvantages?

other turbo options? probably think i should upgrade to lowmount turbos due to the police factor.. so maybe some 2530s or gt- rs??

thanks so much fro all your time!

Chris.

Hi Chris;

I'm interested too since I've gone and bought some R34 N1s and your car sounds identical to mine. Prior to purchasing I found quite a bit of info on the forum, there is a very long thread in Forced Induction Performance with lengthy discussion on just about every type of turbo ever fitted to a GTR. A search with 'Sydneykid' and '2530' should get results.

Mine are R34's so I'm not sure the results suggested for mine apply strictly if you are looking at R32/R33 N1 units.

About $2500- 3000 should net you something good. I don't think there are disadvantages apart from purchase cost; more boost, better durability etc but then there's tuning and so forth that all adds money. The 2530s also seem to be well favoured as a good street package.

there are 7 or 6 type of N1 turbo for R32 / R33... good luck for your research.

I got mine for the price as listed above. Currently I am making 401rwhp @ 19psi on the Formaz dyno over here in Perth on a very conservative tune, which I've heard is a pretty low reading dyno. No idea on what it will run down the 1/4 but soon to find out. Going to head down in a couple of weeks if all goes to plan.

Disadvantages are obviously the whole host of other crap you need to buy to really help wind the turbos up. So if your car is relatively stock then you'll probably need PowerFC, Injectors, Pump to see some good numbers out of your car. But before you do that just check that your engine is ok to begin with. Don't want to go winding it up if the engine is shithouse.

Like calvintys said, there are a few differnent types of N1 turbo. Zoom or HPI did a good write up on the turbos and I will see if I can find it, so I can scan it and post it up for all to see. But they basically outlined that the major differences were that:

- One variant of the N1 turbo is basically a standard GTR turbo but with steel wheels,

- And the other variant of the N1 turbo is a "Group A" spec turbo which has 0.64 housings (same as 2530 I think?). These are the ones to get!

From the top of my head the R34 N1 turbo is rated at a higher HP because it has a slightly different spec (read: bigger comp wheel). So it obviously should be good for a little more HP.

Hope this clears some of the issues up.
