Ard is $500 plus post, direct bolt in 150amp 

OK cool.

So exactly the same as the LS upgrade through CWC, a quick search shows a few people using both without too many dramas?!?

I got the CWC kit with GM alternator and the car starts and runs so much better than before... I replaced it a while back and so far so good! Fitment was perfect and he was really easy to deal with! Was about $500 for the kit from memory!

Yeah same price, I’ve got the ard one and never had an issue, it also worked out well when I went dry sump because it requires a factory fit alternator

Tried searching for this locally but it appears you can only source from the likes of RHDJapn etc?!?

That was where I got mine from, postage was pretty quick from memory

Cheers!

So first test drive on good rubber resulted in me destroying a brand new RE71RS :(

The front brake duct decided to dislodge itself from the bumper, get stuck between my tyre and brakes resulting in a 4mm gouge.

The white smoke it made had me very concerned so certainly could've been a lot worse...

so i tried a log, no idea if this will upload but here goes...

second to third it appears as though voltage drop to 12.7v roughly...

also hitting a cut now, maybe low oil pressure seeing how well it hooks up with the good rubber... tried viewing the safety cut for oil pressure but can't seem to find it...

 

second to third pull - 07022023.llgx

Same, RHDJAPAN for ARD alternator as they are essentially a rewound factory alternator so no bracket conversions  They have a slightly bigger pulley but still fits the factory 4PK875 belt.

Have you been back to Ampl ? Sure it's not fuel ? Refresh my memory with what coilpacks you have and what fuel pump, fuel line sizes and the pump wiring size is. Has Ampl suggested what dramas the low voltage is causing and / or this mentioned cut is related ? A drop to 12.7v is not ideal but really shouldn't be causing you major dramas like a cut.

Bloody cars....

Cheers Ben..

The cut is from low oil pressure... Wish I could say I was surprised but was kinda expecting it running standard sump with only a Tomei baffle...

I did the pull with the oil only being at ~45 degrees so my tuner (Ampl) is saying that won't be helping things (50w oil) and suggested i try a pull and log it again once oil temp is 80 degrees +

So the log above is showing when the voltage drop happens fuel pressure drops and my duty cycle is getting up around 92-93% (1250cc Bosch Injectors), hence why he didn't want to wind more boost in until the voltage issue is sorted...

Coilpacks are 35 GTR (Hitachi)

Fuel system is very simple, Aeroflow intank pump (460LPH from memory), standard fuel lines, pump wiring had a direct 12v feed but I can't recall what gauge wring (was done 6/7 years ago...)

Cold oil will show higher pressure so not sure what he is thinking there.

 

Also not sure what you are thinking with 7000rpm and cold oil.

Oil pressure dropping is bad.. ... you need to fix that!

Time for an extended sump, had exactly the same problem with mine once the single went on (stock sump/tomei baffle) you can add an extra liter of oil as a band aid and it’ll work most of the time and trip other times

I believe he's referring to the fact that with colder oil it will take longer to get back to the sump?!?

I had been idling for over 10 minutes and drove sedately for five minutes before giving it that pull... Not having an aftermarket oil temp gauge obviously failed me here cause I honestly assumed it would have been up to temp by then...

ye it is overfilled by half a litre.

I'm going to take it for a drive tomorrow once it's above 80 degrees and log it to see what happens..

If it still cuts i'll put another half a litre in and if still no good i'll have to look into extended sumps once the bank account shows some signs of life again 🙃

so i went for a drive this arvo..

set the laptop up and waited til the oil temp was above 80 degrees and then did multiple second and third gear pulls to ~7000rpm with no cut..

I think i'm still going to add another 3-500mm of oil taking up to close on 6L and see how things go..

I do realise inevitably i'm going to need a bigger sump sooner rather than later..

    • 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.
