Not much achieved on the weekend, resprayed the radiator air deflector as it was flaking..... Replaced some dodgy bolts with nicer stainless items and cleaned up the 2 front A/C brackets, so much to do.........

The fuel cooler is setup from the return line to the cooler then to the surge tank.

Ahh ok cool, the same way i've done it then.

Is this the 'best' location for it?

Have any of you guys got a temp sensor in your fuel system somewhere? If so, where?

I'm putting one in mine, my idea was to have it in the return line just before the fuel cooler.

No temp sensor in mine at this stage, however i would love to be able to monitor it....

And yes i believe the location is the only spot for it, it is setup similar to the Z tune i think :)

I would put the sensor just before the fuel rail so you know what temperature the fuel is when it gets to the engine. Knowing what it is pre-cooler doesn't help much?

My reason for putting the temp sensor post fuel reg, in between the fuel cooler is this should theoretically be the hottest part of the fuel system?

I would imagine so, either location is still going to give you an indication if the fuel temps are rising.... I still find my surge tank getting hot which i dont think is normal, however everything is running optimal so i guess it is?

One thing i did learn is that the fuel cooler has ruined my normal jacking up procedure, if i jack the back first it makes the front too low, now if i jack the front first i get this -

LOL and yes that is a snap on super low jack already!

All good, will just have to change the way i do it!

And i broke another POS ISC arm in the rear, they flog out or break in no time! Garbage! So i replaced it with more cheap stuff for now until i can afford to do it properly -

GKTech make billet ones, no welds ;)

This will need to be my next purchase i think! I have now replaced the shitty ISC front caster rods with GKTECH arms and the car feels so much better! And they are so light too!

How is the tank plumbed from top to bottom?

There are 4x hoses that connect to the surge tank. All should be at different heights. But some tank are different.

Eg theres two ways to dot it.

From top to bottom;

1.

- Return to main tank

- Return from fuel rail

- Feed from main tank lift pump

- Feed to main pressure pump(s)

2.

- Return from fuel rail

- Return to main tank

- Feed from main tank lift pump

- Feed to main pressure pump(s)

Which way is yours done?

The 1st option heats the fuel as the surge tank has to be pressurised to return fuel to the main tank. The main pressure pump and the lift pump have to work harder to fully fill the surge tank allowing fuel to flow out of the top fitting back to the main tank.

You want a small air gap at the top of the surge tank with the return line back to the main tank jn between the return from the rail and the lift pump inlet.

If that makes sense?

I just double checked so i didnt get it completely wrong :P

Fuel tank to surge tank, feeds twin 044s to twin lines to each side of rail, center of rail returning via fuel reg to return line to surge tank over flow to fuel cooler into fuel tank, tank feeds surge.

Loving the build mate. Engine bay looks clean and stealthy...

Thanks mate! Makes it well worth it when not only do i get to enjoy the car BUT i get people appreciating the hard work and money etc that goes into such a build ;)

    • Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks 
    • The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.  
    • There's a good German place in Brisbane if youre up for the drive 😛
    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
