so we're pretty much the same then. Built 26, 2530's. ID1000's and intank Nismo. That's it :)

Full time Eflex use (unless i need to fill up with 98 if i'm not near an Eflex outlet, then i just let the flex-fuel setup take care of things) but 95% eflex use, couple track days and about 6 months i think on this setup

Its about 5 litres in capacity, Nismo "lift" pump (as that what was my intank before the surge tank was installed) and 2 X 044's to feed the engine. I have a Fuel pressure Gauge sitting on my steering column and at no point have I seen pressure drop either on the track or on the street.

I took the car to Unigroup and said "I want a 5 litre surge tank with 2 x 044's, go" and that's what I got.

It may look like it hangs low in the photo's but it definately doesn't.

Piggaz that looks good, can you see the tank from behind the car?

Only when he is going over a crest and you're following at night your headlights will shine off the very bottom edge quickly - so it's very well hidden

Yeah, as Steve said above. Ill take a photo tomorrow and upload it. I'll stand 15 M away to give you an idea. If I just got off my arse and sprayed it back you would be hard pressed to see it.

we all know u will never do it as it would fall immediately into the 'too hard basket'

Nice Setup.

Which brings me to a question - what is the general thought on mounting the pump or pumps in-surge-tank. ie in the surge tank immersed in the fuel?

I have a 044 in tank (main tank) and it runs almost silently, I assume it stays relatively cool and free from corrosion being in fuel. Certainly when you take the 15 yr old stock pump out it looks brand new, as does all the wiring/fittings etc.

Any reason people don't do this other that it being (maybe) more complex?

And also, rather than running duel 044's, is no one running big single pumps like Fuelab, Weldon etc?

I'm looking to do E85 setup soon and so looking at all these options.

    • Your car was auto before? You have different diff ratio (auto vs manual i think? or n/a and turbo?)
    • +1 for getting a screen off alibaba, CarPlay/Android Auto is vastly better than whatever navigation cars had 10 years ago. I got an Android screen for my 2015 BMW, huge difference. Fully compatible with factory stuff including iDrive controls.
    • Yeah, my offer was more to show exactly how rough and ready the rig can be and still be useful. Youtube vids will definitely show cleaner setups. Same concept though.
    • I would guess the seal has gone down at the speedo drive and gearbox oil has crept up the drive cable sheath and fouled the speedo head.
    • Any updates on this? Although not a stroker, nor built especially loose, my car has the exact same symptoms. Although I feel they were not there to begin with. Since rebuild with forged parts I have done about 40k kms and it feels like during the last 15k or so, the oil consumption has gotten progressively worse.  Compression test showed - what I thought at least - similar 10-10.5bars in each hole without oil. I have not yet done blowby test though, due to limited garage access. #2 plug is the looks the most foul and that was the one with 10bars. Nothing in the breather tank. I only recently disabled PCV and left only the hoses running from the valve cover via smallish tank to turbo intake pipe there and did some mildish 2nd gear pulls so the car was definitely on boost (1.4bar or so). Removed a hose from the tank and it was basically dry - meaning, the wipe I used had basically no oil on it. Last time I checked, the turbo and IC piping seemed dry as well (will have to see about that again after those pulls). For the past year and a half though, the car has been driven like a granny would for 99.99% of the time, since it mainly serves the purpose of carrying the family around nowadays. A lot of slow, stop and go city driving and most of the trips it barely sees any boost, but gets up to temp properly every time. Although there can be weeks it is not started at all. The car does not smoke, or at least not that I can see. (CAT is in place though). There is slight visible sweating at the Ex cam cover seal and I recently tightened the oil cooler lines as there was some mist on them too. It runs and idles extremely nicely and feels all around healthy. Like TurboTapin, I too am suspicious of my turbo. I have had IC pipes pop out from 1.6-2bars of boost a half a dozen times during the years. The turbo is a HX35/40 hybrid. So, a very similar mystery. Around 1500kms and a litre of oil surely cannot disappear to thin air. Apologies for the wall of text, not sure if any of the above is useful for best guesses/things to check next.
