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

    • If the RB29 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.
    • Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.
    • Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice  
    • Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
    • My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
