I have just installed early N1 turbos on to my r32 GTR and just wondering what boost these things are designed to run at. At 13 psi only make 10kw more than the standard ones at 13psi.

Mods are filters,exhuast and power FC.

Any help?

Thanks

they should be right at home when running b/w 16-22psi.

i have a similar question, I'm getting N1 turbos installed on my GTR as we speak, the car is standard, other than full exhaust system and aftermarket airfilters, how much boost can i safely run, without risking damage to the turbos or engine?

I was thinking around 15 pound max?

Hey sounds the the same as what ive got. Car made 220 with standard @ 13 psi and now 230 with N1s @ 13 psi . Sounds like the turbos are made to run higher boost but how far can the standard pump and injectors go? I was hoping 250-260 with 18 psi. See what the skyline gods say :P

Id upgrade them to be safe anyway, if they havent had a good life and are on the way out this could be a recipe for disaster. No one likes having their engine lean out and go pop.

mhmm.

Pump and injectors would be a wise investment if you're going to be running around 18 pound.

heres another SK quote for ya...

N1's are OK for 1.2 bar, but nothing to do with breaking them. They just get a bit inefficient over that and heat up the air a bit. Boost is irrelevant anyway, as you do other things to improve the efficiency of the engine you will find the boost goes down but the airflow goes up. And airflow makes power not boost.

I understand that FLO is better than boost.But was concerned that runing the N1s at low levels was a waste off time.Good to know that they are efficient up to  1.2 bar but whats the other end of the scale? Is it a waste to run them at .8 or .9 bar?

Well I should know for sure on Friday......well be going on the Dyno hopefully, if nothing goes wrong, and I'll see how i go at different boost levels.

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
