hi I have a 89 r32 gtr.

Like it says in the tittle i am chassing around 300 to 350 kw at the wheels. I have 2860r-5 turbos and wanted a descent fuel set up to support them. I have just purchased sard 800cc injectors and was wondering what fuel pump to use. At this satge I don't really want to make/ buy a surge tank but i am more after a good intank fuel pump. I have being doing a bit of research, though it has all conflicted each other.

What are the Bosch 040 good for or a 044 mounted in the tank (hp/kw wise) Or can somebody give me another option. I don't want the pump to be maxed out at the kw I am chasing

Cheers

Thanks to all the people who have replied to this.

Is the Bosch 040 good for 600hp or 400hp? I don't want the pump to be maxing out at around 350kw. Is any body using the 040 in a gtr with similar power figures to what I am chasing?

Cheers

according to the specs (4.7L/m) that nismo state for the gtr pump it will out flow a 044 but what it doesn't say is if that is free flow or with pressure.

i just put a 044 intank (R33) and you can barely tell the difference noise wise between it and the stock pump, i used 3 pieces of 25mm fuel resistant PVC tubing opened up and wrapped around the pump and the arm it mounts too.

will nismo in tank support 380awkw?

Put it this way. Twin RS's at anything up to 2 bar on a 2.8 litre stroker and im fine (Fuel pressure gauge in cabin to confirm). Your turbo's are smaller so you will be sweet!

yep, no question, nismo pump is the easy winner. it mounts properly in the stock cradle too which is a problem with other pumps. if they are not mounted correctly the pick-up can be too high resulting in fuel starvation. and the nismo pumps are 276 litres per hour, rated at 3bar (ie stock base pressure).

i got a bucket of dead walbros... want some spares.....

And my walbro is relagated to lift pump duties upto my surge/044 setup as it couldnt maintain flow above ~50psi rail pressure.

I'd be interested to know what setup a Walbro makes 380awkw with :cheers:

Snowman was/is using a stock R34 GTR pump for 380rwkw, so anything aftermarket is gonig to meet that easily enough

      new 1.5 LSD issues/concerns

      By Kinkstaah · Posted

      What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
