Hey all

My injectors and fuel pump is on its way to change to e85.

How do people go about this?

Will i have to fully drain the fuel tank? Easiest way of doing it?

Any form of cleaning needed? Clearing fuel lines etc?

Will then install the pump and injectors, fill up with e85 then trailer to the tuner?

Thanks

Easy way to drain the fuel tank is to simply run the fuel hose into a bucket and turn the ignition on and wait til it stops coming out, shouldn't need to clean anything. Edited by AngryRB

obviously you can't change your fuel maps until you get to the tuner. Drive over on regular old 98 with a bunch of e85 in fuel drums and drain your tank there.

as for the injectors probably get the tuner to install them seeing as the car probably wont run at all on huge injectors

I recently did a similar thing as my car is being retuned on E85 in the next couple of weeks.

I replaced the fuel hose around the fuel rail / fuel filter with some Gates Barricade stuff from Repco which is apparently bio-fuel friendly. Installed the injectors at home. The hard lines I left as they were.

Also pulled the fuel tank out of the car when I changed the pump over (don't forget to upgrade the wiring if you haven't already) to make sure that it was clean inside (couldn't really see that well in the garage with a torch) but as it turned out it looked like new. I've read elsewhere that if your tank is dirty you can throw in some E85 along with a few marbles or ball bearings and swirl it around. I also replaced the hose inside the fuel tank with the Gates submersible stuff to be safe.

I'll fill the tank with E85 and get the car picked up by a tow truck. Easy!

If the pump has a direct rewire then this will work

^^ if the car is stock pump/wiring then this wont work , ignition on- fuel pump primes for a few seconds then switches itself off

This. So easy. Put said fuel into daily.

Or, drive car to tuner, do the above and change injectors there.

Done.

as mentioned before stock or correct wiring won't let that happen. The pump only primes for a few seconds then turns off as a safety feature. A hard wired pump that's always on with ignition isn't safe in the event of a crash.

Even if you start the car?

Ahhh, pull of the return line! Now I get it! spazzed out a bit :)

Lol. I wasn't very clear.

Pull return line off post regulator, put a long hose aiming into a bucket. Start car and wait for it to stall.

Job done.

Crack open a beer.

alot of crazy ideas for draining the tank here so heres mine,,

run hose from fuel filter to drum

If you have your pump wired for full voltage like most do, direct to battery...

I just stick a screwdriver and short the 2 pins on the fuel pump relay....hold it there till tank is empty....don't even need ignition on or a key in it for that matter....actually thinking I should just install a switch there even...to make fuel swaps easy

      first time swapping rb25det into r34

      By Duncan · Posted

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too

      first time swapping rb25det into r34

      By dingleberry · Posted

      hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy

      SAUNSW - World Time Attack Challenge - 5 & 6 September

      By Keeper · Posted

      Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
