Marko how is the Nitto oil pump going for you? What sort of oil pressures do you see hot?

- on cold start up it is over 6bar

- warm idle it is 4bar

- normal driving it is just over 6bar

- when i push gets close to 8bar

HEAPS of pressure on hand :P great for the main & big end bearings!

i am 'thinking' of upgrading the rear housings on my -10's (i probably wont be arsed yet its good to know anyway)...anyone have experience in running .86's in a twin (or single) configuration as i would liek to determine the power gain & fitment challenges as below:

- the requirement for customised dumps

- i was advised that .86 rear housing is more suited for single applications & that it might become too laggy (i dont want lag but maybe i can get away with it on a 3ltr)

- i wasnt sure if there would be adequate room & clearance to run the larger turbos in a low mount position?

here is the website, shows .86 option but no technical specs:

You dont think they would be a little big for the street? Run E85 then if you still want more (you nutbag) then go the bigger housings?

E85 isn't a bad idea but the inconvenience will definitely do my head in.

With the larger housings I do question the possible lag and clearance issues, anyone know what they are rated at with .82s?

i fitted the new plugs & splitfires - runs like a dream & seems to hit harder all around :down:

i know its probably better for the coil packs to run without the valley cover as they probably get more air ventilation, is this more apparent on the track though as mine is a street car (and the valley cover adds bling to the engine bay :P)

yep you should run the largest gap you can without missfiring, bigger spark = better burn = more power. 1.1 is ideal but many people gap them down as low as .8 under larger boost

Hi guys,

When i 1st ran my car over the weekend with my new coil packs & new plugs bcpr7es (gap 0.8mm) it was fine at the time but i only drove it for 10min. I started the car again last night & right from the onset on idle it was carrying on, coughing, very rough & could barely reverse it on flat ground so i let it run for about 10min & the idle slowly became cleaner but as soon i revved it the engine was extremely rough.

I checked the plugs & they were black like powder charcoal – very rich!

I then put my pfr7a’s (1.1mm gap) back in & the problem was fixed, drove it for an hour with no issues 

I am trying to sum up a conclusion as to the cause...both plugs run the same temp sooo it must be the gap right?

As u suggest Duncan, the larger the gap the stronger the spark & better fuel burn? It was tuned with pfr7a’s @ 1.1mm gap.

I am guessing that if i regapged my bcpr7es @ 1.1mm they would be fine.

  • 2 weeks later...

hi guys,

i had my gtr on the dyno for a quick health check & i asked about my exhaust (steve N1GTR prompted me on this, damn you mate im gona go broke hehe). im currently running a hks superdrager which is 3.25inch at the front, then steps to 3.5inch mid way & finished with 3.75inch at the diff.

my tuner told me if i wanted more power to increase size & run x-force front pipes (2 x 3inch pipes which collect into a 3.5inch) then with a new 4inch all the way thru to the rear.

he told me i should expect 20awkw gain or more as the larger capacity rb26/30 really doesn't like back pressure :ermm:

1 of his customers cars made more than 20awkw. where does it end haha

Thats exactly what Racepace told me when I asked them about building me a mines style front pipe with a 450awkw goal with my new engine. Bummer was that they couldnt make the pipe for me without me sending the car down to them though, seeing as all systems are custom made to fit.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
