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

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

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.

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!

      You think its the AFM? I know its a common issues on R32s. I find it coincidental how this issue raised right after cleaning the fuel system. As everything except the fuel system was fine before. I tried running it with the IACV unplugged but did not notice a difference and still stalled. However, the RPM gauge is not in the cluster right now, so I will need to connect the laptop again and use Nistune to check the RPM. I will check this weekend.
