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

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

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

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

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.

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.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
