Dyno tune will be a while still when I'm ready to adjust the cam gears.Until then its road tuned

N1GTR.. Technically the only thing new about this is the actuators, and I'm sure if you purchaced -9 from gcg etc. they would put on the same 8.8psi actuator like what I got. Otherwise, same -1 / -9 / Gtss unit.

I think response can be tweaked further with the tune and also with boost control as there is no creep and very minimal spike(1psi) as is right now, so definately some gain to be have there, even if minimal.....and then there are cam gears

Have only been driving it a few days, but it does pull a touch harder on 13psi, But so far I'm satisfied that I have turbs capable of 300rwkw with stock like response.

Aaaaaah my bad!

Here's what I thought you meant;

This is the last dyno tune I had, -9's, nismo pump, 555cc injectors, nismo AFM's, cam gears, stock engine.

Figures in all wheel killerwasps.

Since then I have fitted a different boost controller and the wastgates are now set to open at 16PSI with controller off.

Needs another tune to set boost controller and get rid of the drop in boost pressure. 22PSI tune to follow.

I'll let you guys know....

Aaaaaah my bad!

:thumbsup:

I guess they didn't say anything about injector duty.

I was seeing roughly 90% on a cold night with 22psi peak in the midrange through to 17psi or so at the top end. Rich enough to see black out the back on full boost :whistling:

Stock fuel reg too....

Should be okay, guess I'll find out.

Well since there is NO info on this here I just thought i'd put this up and update as I go along.

The comparision below is results for the -1 turbo which is the -9 that comes with a 8.8psi actuator from Garrett, compared to stock R33 Gtr turbos.

The top window is the -1/-9 which reaches the same level of boost(13.3psi) about 200-300rpm later than the stocks, and the car drives basically the same as before.

The ONLY thing changed was the boost level was raised only one notch on the controller (profecb2) to get the same level for comparision....start/gain etc was left the same and the pfc tune was untouched.

My boost control kit reads 1psi low for some reason, hence 13.3psi

Ignore the scale on the bottom as this would be different due to the length(secs) of each log

Well with two turns in on the actuators I was able to get it down to stock like response, well on paper at least....To me it feels even better than stock coming into boost

Top -1/-9, bottom is stock

Is boost creep the only thing to look for with too much preload? I want to shorten them some more :yes:

    • Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics
    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
