I have yet to see anybody say A88 dump tubes fit without work lol..looking forward to seeing your fuel and engine management strategy..what is your goal with the -5s?

Power goal is anywhere handy to 500whp after this winter (more parts coming). I figure it will a struggle.

Engine management and fuel delivery is going to be redone this winter as well along with a few other things. I had bought nistune to replace the chiped ECU and larger injectors with new FPR.

Last dyno session before storage. A bit shy of my 500whp goal.
Current set up posted below. Input needed.

Dyno Video - www.youtube.com/watch?v=Kb-pw7gRLzQ
400whp 310tq




Setup

Quality 89 octane pump gas
750cc injectors, Stock rail, Tomei fuel pump
trust front mount, hard pipes, blitz bov
300zx maf's, apexi suction kit.
19psi on gt28's
Apexi GT spec down pipes, apexi cat back, no cat.
Tomei type b pon cams, no gears.
11.2-11.7 AFR
AEM 50/50 water/meth kit
Timing pulled down to 17 degrees at 5500-7000
self tuned with nistune

Problems.

Lean out at 7000rpm. Fuel pressure starts to drop at 6800 between the rail and the filter.
New rail, lines, or larger pump?

Nistune is not ideal with no knock maps or knock detection and no access to start up tables. Hard to tune partial timing.

Haltech or AEM ems?

Besides poor fuel, what limiting factors am I missing.
I hear to often that 500whp is "easy" with a rb26. Everyone you talk to seems to know someone with one thats makes this power.

Sounds and looks great

Nice looking sleeper! Barely tell it's got mods done, great work.

Didn't get Akita if power for 19psi, must be the low octane fuel?

[PurpleStreak]

Doesnt Nistune have 'Fuel Map' and 'Knock Fuel Map'?

From Nistune manual:

If you find that your changes in the maps don’t seem to be having any effect then check that the ECU
hasn’t jumped to the knock maps. This is easy to check by selecting the IGN timing maps and then display
the Gauges panel. Note the values being accessed in the maps (don’t forget - the ECU averages across 4
cells) and check that they correspond with the IGN timing value reported in the Gauges panel.

Thanks, I know fuel is a large factor when it comes to power.

Nistune does have the knock maps but I have never been able to get nistune to go to them even when detonation was audible.
I was told that the version for the rb26 didn't support knock detection. So because the knock count remains at 0. The ecu will never try and go to the knock map. Knock maps are turned on but they are never accessed.
It's kind of useless to tune ignition. I used old school methods. Just keep adding timing until tq reaches peak then back off a few degrees and pull spark plugs note the changes on the electrode. Not the best way but it works for WOT just a bit more trickey with transition area and part throttle.

Fuel on nistune does respond. I can add 20% more fuel threw MAF translation map with target AFR in fuel map set to 11.5 and still it leans out even though I can see the injector duty cycle increase.

I will post up fuel and igniton maps. If someone can pick up on something off please point it out.

Fuel- very top right was done on fuel map not MAF translation to stop from leaning out.

Time for a Change

Well I thought about what I didn't like about my current set-up and I decided everything is just OK, but not exactly the way I want it.

So time to revisit: Engine,Suspension, and Interior.
Engine: wasn't efficient. Nistune has limitations, more response needed, and too much blow-by oil in charge piping.

So to start.

Winter Project 2012
New year, Lots to come but first out with the old.

Start



Bumper cover and support removed.



Battery and charge piping removed



Intake side mostly removed



PS Pump turbo piping removed.



Rad and intercooler out and AC condenser permanently removed.



Front Turbo removed, AC compressor gone.

Wow AMAZING GTR man. Im really looking forward to seeing whats coming next

[speedracer1610]

What is in the Blox box???

[allwheeldrifter]

...

very nice, i like alot.... similar to what im doin this summer.....(same turbos, cams and mafs...)

[Imation]

What is in the Blox box???

just a few universal dress up parts.

just a few universal dress up parts.

oil filter relocation kit?
