I can't see why the surge tank would be a problem. You may not be happy with Brad but that doesn't make his aluminium corrode. Plus I've been running one of his tanks about 12mths longer than you without any issues, there are plenty of them out there.

I think you need to look somewhere else. Feel free to point and laugh if I'm wrong

everything has been replaced

and now i can trace the source of the shit due to the multiple reusable filters

and there is definitely gritty alloy like stuff coming out of the surge tank

either way i will pull it apart and find out if its the problem

and put a fuel cooler on it now

Brad had a bad habit of not cleaning out his well-crafted parts properly and maybe that could be your problem big fella. I would stick with the fuel you are using,,,it has to come good sooner than later.

I have a purpose built fuel cooler off an X5 3.0l Diesel that you can use tiger. I currently run one on my car and it works a treat. Here's some pics for your love.

Plumb this bitch straight into your return line and cool that fuel baby.

Cheers

Neil.

There are some fuel cooler pics on this page -

Not sure if its helpful or not.

Thanks for that mate, I looked before but gave up cause to many pages lol

So that is just a regular 23 row oil cooler with a custom air duct/protector ?

Looks very nice and neat :thumbsup:

Yep, it will need some relocation or modification if i ever get around to doing underbody aero stuff... Its not really copping any air due to the diff being in its face but the fuel pumps have been nice and quiet since its been fitted so its certainly doing something, since the issue has been sorted we have not bothered logging fuel temps etc...

Neils compact design is probably a lot more practical and obviously more cost effective :)

  • 3 weeks later...

so last track day i noticed that after a few laps she started to get lean
and after about 6 hards laps would develop a missfire

so naturally i though my fuel was clogging my injectors again
checked them at the track and seemed fine
had them flowed and they were fine
anyway the internets told me when e85 gets real hot it leans out
and i decided that my surge tank was running dry ( its only about 1 litre and a average design)
the insides of the cheap alloy had ben oxidising and running thought the fuel lines as well
old setup
surge2_zps7e38a2c1.jpg
ill stick it on my r31 i think as it loves fuel surge

so fuel setup number three was drempt up

biggest walbro you can buy for the intank
fuelsetup4_zps57400d77.jpg
alloy 2.5 litre tanks( anodized so it does not corrode)
trusty twin o44's

    • 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.
