Hi

my current power F.C. map is for a basic setup including a hks2530 on a rb25 neo. Was mapped to 1.3 bar with usual supporting mods, intercooler, r35 injectors, stock afm etc etc. with a conservative road map

the car is away at my mechanics getting a new setup fitted, gtx3076 gen2, 6 boost top mount, turbosmart external gate, stock plenum remains in place. 

I will plug the standard afm back in, would this be ok to limp back to my home with keeping below 2500rpm and no heavy throttle?

i will map it from home with a friend and change to a z32 afm then

Next part of my topic

its a unopened neo run on 98 ron. Not after lots of power, about 1.4 bar max would be my intended boost, would that be safe enough? I don’t want to risk the engine to much

 

few pics of the fabricators work, I know i expect to hear should have ditched the plenum and throttle body and stuff, but at the lower power goal at this stage it will be fine, next year I may add a head gasket and studs etc, at that point I’ll privably change the plenum

thanks all

Lovely fab work :)

Boost doesn't kill motors, just keep the timing pretty sedate near peak torque and you could run close to 2 bar without it going bang on a NEO.

FWIW, I did 1.8bar into a non-NEO motor and abused it on the track for ages till it lunched itself, however it had barely any timing in it in the mid range.

Lastly, I would ditch the Z32 and run a HPX N1 card AFM as it doesn't suffer from reversion like the Z32 does.

Cool boys, thanks for that

its a road car so reliability is the thing I’m after not every last horse from the engine.

first thing when home is to check base timing is correct, it’s me and a friend tuning it, he’s quite clued in but the z32 will be easiest for us as it’s directly supported by the power F.C.  

I’m not familiar and I did try do some research about a r35afm before but it was not as straight forward as I would have liked.

Ok chaps the car is home, super

 

can anyone tell me, if I swap the z32 in (and what wires I need to join) and reselect z32 in the power F.C. hand commander, will the car still drive again or will it certainly need mapped again even for light car moving ? 

Should drive fine.  That's the whole point of having the curves for the different AFMs ready to go.  but it will need to be tuned before you put any significant load on it, because it will not be right enough.

As to the wires.....google is your friend.  There would have to be thousands of posts on the topic just on this forum alone.

  • Thanks 1

You need to look at stronger valve springs at those boost levels.  That's about the only hardware that really needs attention assuming the tune is right.   

 

As for driving before tune.  If you have the same injectors and AFM then it should run fine under vacuum and very low boost (1 or 2psi) .

    • My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.
    • Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?
    • What about if you just give it direct 12v and earth?
    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
