So the option to go with an eflex setup is becomming more attractive but the part that still has me questioning is the fuel supply set up.

I have a 34 GTR and theres a fair bit of infor for for 32/33 guys about especially in regards to twin intank.

This option seems more attractive as its hidden and the associated fuel smells with surge tanks that some people get.

But the cost of going twin intank seems to be $1000 for the cradle (from power tune) plus the fuel pumps.

But surge tanks seem be available for around $200 plus fuel pumps.

So what other options are available for intank, $1000 just for a cradle just seems to be rather expensive.

As Scotty said mounting two pumps in the tank isn't hard.

To do it right you really should get the correct bulk head electrical fittings and run separate power supplies into the tank.

I've seen a couple that people have linked the pumps together using the original plug. It draws to much current and melts the connector.

Also you can either join the pump outlets together inside the tank and run a -8 bulk head out the original sender lid.

Or block off the original 5/16ths outlet port and install two new -6 bulk heads into the sender lid and run dual fuel lines.

I dont know if it was just because my intank was mounted wrong or not but without a surge tank my car runs out of fuel under hard cornering when Ive got less than half a tank.... never had an isssue on the street, but on the track its a different story...

not dead set on a in tank, just looking at available options.

Also will the new 400l e85 walbro support around 360kw with e85, and has anyone used the fitting kits that come with the pumps that states there for 32/33/34 GTR....

Some one on here (cant remember) did the figures and reckons they will do up to 450rwkw on E85...

i know Piggaz was going to fit one as his lift pump to his surge tank but there was a bit of work involved so he just went with the 044..

dunno if it came with a gitting kit.

im using 2 of the 400's in my surge tank... so quiet :D

Awesome thanks for the info on the new single pumps. If anyone has fitted one of these to a 33/34 gtr and can say how the fitment was or how they did it that would be great, especially with the pickup being away from the pump itself

Ok I have gained all the info out of this thread and various PMs with other users.

I will summarise what I have gained for any people looking into this for the future:

The new walbro 400L seem the go, but make sure that you get the new design the doesnt have bleed holes otherwise your going to have issues when it gets under 1/4 tank because the first edition 400L need to be completely submerged.

Nismo is holding up fine for ss8_gohan with nearly 400kw, so if you have a nismo and arent planning to go higher then keep your nismo, no surge issues etc.

Twin or surge tank setups is for the big power.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
