GTR turbo info needed...

[R32_GTS4T]

Hey people, I was wondering if someone can tell me the differences between R32, R33, R34, and N1 spec GTR turbos, and how to tell them apart?

Seems that the GTR I bought off Andrew last year has neither near new, nor R34 turbos - they are completely stuffed - oil seals gone, heaps of play, and nicked wheels, so I'm looking for another pair.

Seems there are some well priced near new pairs out there, but I'd like to be sure of what I'm getting since I've been burnt once already.

Also, what are people's ideas on N1 vs 2530 vs GT-SS turbos, given that I liked the spoolup on the current turbos (usable boost at 2000, full boost of 1bar at 3200), and that I'll probably do some mods over time (like Power FC, dumps, etc), but don't want to do any internals (except maybe cams - I already have adj cam gears)?

Any help would be appreciated before I splash out next week on a new pair to rescue my car from the workshop (I've been pining for 2 weeks already )

I have heaps more info....what else you want to know??I have 2 BNR34 turbos in the shed also

If your looking for an upgrade and want roughly the same spool time as standard turbos why not go for HKS 2510s ? rated upto 550HP IIRC

[R32_GTS4T]

Cool, thanks for that ylwgtr2...helps a lot to figure out what's what...

I know that the N1's are non-ceramic, but what about the standard R34's ?

Are the 2 you have stock R34 or N1?

Hey DeanJSL, yeah...seems that for what I'm looking for, a pair or 2510/N1/GT-SS should suit fine.

[ylwgtr2]

the 2 i have are from my 34 Vspec...i went for 2530s

[R32_GTS4T]

Well...after much deliberation (and a ton of reading) I'm going for a near new pair of R34 NUR spec N1's.

Should have them by the end of the week

It'll be interesting to see the difference to the old ones...

[benjiman74]

Sounds nice, whats the difference in specs between the bcnr34n1's and the nur's?

[R32_GTS4T]

Hey Ben, don't really know if there's much of a difference, if any.

I was actually pretty set on the pair you had, but I'd talked to CHASP last week about this pair, and he rang me today, so I was kinda obliged to take his, given that they were the same price, etc.

[autObarn]

trust t517z x2, on the road they felt like they spooled quicker than stockys and had heaps of low down torque,and they still ran over 300rwkw!!

[R32_GTS4T]

Yeah...it'll be interesting to see how these go...gonna have to boost it up a bit now too

I had a comfortable 225rwkw before, and the car felt wild as it was...

Hey Troy, I just clicked who ylwgtr2 is... is your GTR back on the road yet?

[GTR STI]

As far as I'm aware The only difference between the R34 N1 and the R34 N1 NUR spec Turbos is that the later came with Nismo extensions.

There were only 100 R34 nur spec. GTRs produced.

I have an as new set for sale at the moment with the Nismo dump pipes.

$3750.

Ok. I was offered the dumps with them for a bit extra, but I'm a bit cash deprived at the moment , especially since I might yet be up for more engine repairs (the turbo replacement is stage two of the fault finding).

I think dumps will be the next thing to go on my car, I know what a difference it made on my last car.
