R32 Gtr N1 Turbos

[RUSSMUSS]

hey guys,

i bought my gtr about 3 weeks ago and when i bought the car i was told it was running

n1 turbos, but the owner had no prove of then so i just assumed they were standard

(besides being quite laggy) until i put it on the dyno and realised it is very laggy,

does anyone else have this much lag on standard turbos???

or can any help comfirm there n1 turbos???

im new to gtrs but have spent alot of time around turbo cars

thanks

Shouldn't you be getting around 200kw's for a stock gtr? I would have thought that 243 hp is a bit low. Especially since its running 16psi (to my understanding). Also ive seen alot worse power curves then that one.

[RUSSMUSS]

it running factory boost which is 7.5pd or very close to that, it basicly stock beside a full exhuast

im more interested why it is so laggy???

i would love to see another r32 gtr with n1 s dyno chart just to see when it comes on?? anyone got one??

i have searched it but with no the results im after

[Duncan]

yeah that ramp rate is about right for r32 n1 turbos, I make full boost around 4500. You are not running enough boost though only 7psi. even standard is 12psi and the turbs are fine up to say 20psi.

and what is with hp? haven't queensland gone metric yet? I thought all of australia except WA had moved off the imperial system

[Branelly]

Ahhhh, k i see now. All makes sense. Metric... and the second line is the boost...

[RUSSMUSS]

thanks thats the info i wanted to hear

what sort of power should i see with 16-18pd??

so no chance of being standards ?

im just scared of running 16-18 and the rear turbo wheels letting go

not sure why its not metric

thanks russell

R32 N1's are the laggiest of all the N1 turbos

[R31Nismoid]

Yep... R32 N1's are sper nasty, even R33 one's aren't much better.

No chance they are factory given how laggy they are (unless you have something else wrong).

I have the R32 Nismo trbos, and this curve looks about like my 2nd gear pull. I have seen .6 bar as low as 3800rpm in 4th gear and 5th gear. Turn up the boost and get them in their effienency range, around one bar. Be careful though, stock injectors cant support 1bar from these turbos, neither the stock MAFs as well.

[RUSSMUSS]

okay thanks evryone for there help

it back on the dyno this week so ill post up the results

thanks russell

[payback21]

I would be confirming first that they are N1's before you crank the boost.

[RUSSMUSS]

okay but can you see the number plate with out removing the turbos???

i couldnt see the plates on them.

thanks for the part no numbers

[Angus Smart]

yeah usually you can just make out the numbers on the front turbo..

its a trick angle to look down at also. it will be in the centre of the turbo just infront of where the manifold mounts to the turbo..

[RUSSMUSS]

well after half an hour trying to find the numbers i found them they are r32 nismo turbos, thanks payback21

so its on the dyno tonight ill post up dyno sheet tomorrow

[Jez13]

I have those turbos on my gtr. here is my dyno at 1bar.

[l0WRB]

hey russmuss how r ya mate?

i was the other guy with andrew the day u took the gtr away haha

what was wrong with it???

will be good once it makes some power

[R31Nismoid]

Jez13 - are you sure that is right mate?

230rwkw @ 16-17psi on Nismo turbos sounds signifigantly low...

I say that because the factory turbos will make that much power on 1bar with much better response.

[Jez13]

I wouldn't know if that was right or wrong. It has a pfc, super drager, 700 and sumthing injectors, apexi intake and I think some other bits and pieces. It may have been awkw? The guy that sold it to me took it to the dyno (Todd at top of page) so I dont know the details.

[R31Nismoid]

aw/rw = same same.

Maybe if you get time chuck it on again just to make sure things are A-OK as that result would make me think something is a little off somewhere.
