Hey guys,

Sorry if this has been asked before but i couldnt find the answer anywhere. Im about to upgrade my fuel system with 2 Bosch 044s and a nismo intake pump. It'll also be running e85.

Will my fuel lines under the car need upgrading & what size lines should I use if i do need to change them?

Thanks for your help

it depends on what power you are planing on ? that might help people with an answer, I've been running 600+rwhp on 98oct with standard lines but that doesn't help you ..

am about to upgrade to dash 8 feed and use the original feed for the return, I know someone with 630rwhp and E85 running this exact setup.

if one standard line isnt enough you could use both the feed and return as feeds and then use the charcoal canister line (i assume 32s have them aswell?) or an old hicas line if your not running it for the return.

also a standard pump will more than suffice as a lift pump if you havent already got a nismo.

If it's the same setup that ran 117mph (as per sig) and now just going E85

Stock lines will be more than adequate.

Nah, setup has changed a fair bit now running a big single and looking to push well over 600hp in the very near future. Just want to do everything right the first time.

^ The setup use to be standard 26 with some -5's running 98 fuel and making a soft 400hp. Now its a built 26 with a HKS T51R, JUN plenum, ARC cooler, Titanuim piping & all supporting mods. So if I run 2x runs of -8 nylon braided line one for feed and one for return that should be suitable?

Also the rest of my lines are black nylon braid will this be alright underneath the car?

Cheers guys

    • Hi All, I'm based in Sydney and want to get hold of 4 stock R34 GTT wheel caps as pictured. Cheers
    • Haha im flattered! Although my poor boat is collecting dust in the garage, as it hasn’t been driven in like 6 months. I forgot the to put the trickle charger on too, so the battery is likely toast now.. I have the frenchys kit. It is fantastic. My only gripe was that the hard lines from the firewall needed some tweaking, however, this was mainly due to my specific turbo and dump combo. The weight and size packaging is much nicer too. I think I have some pics on my build thread somewhere.. my justification for the kit was more “why not” I had gone to the trouble to modernise just about every other part of the car..
    • Actually, ethanol has probably never been cheaper, on a tax free basis, than petrol. With fuel excise being what it is, and only being levied on the hydocarbon component, not the ethanol component, and ethanol for non-drinking purposes not being subject to liquor excise - E85 was cheaper, but not because the combustible liquid itself was particularly cheaper.
    • Maybe? If changing the cat to a higher flowing cat, caused the turbo to spool more quickly, and those areas of the map had not been tuned for the boost level it is now seeing, then yes you would need a re-tune. How dangerous it is running without the updated tune would depend on how far out the tune is with the now higher boost levels, how the engine protection has been setup, is the ECU compensating with a wideband sensor, is the boost control closed loop blah blah million other things... But yeah having said that, I wouldn't be surprised if changing out the cat for a high flow, in say a full 3" exhaust, made no noticeable difference at all.
