Walbro Vs Bosch Fuel Pump

Guys,

Basically, I am putting an RB25 turbo onto my RB20. I'll upgrade the fuel pump, and maybe get a fuel reg.

So given that the Walbro's don't flow aswell as the Bosch's, for a target of maximim 200kw, realistically I am guessing 180kw, what would be the best option?

It seems everyone has a go at the walbro's, but unlike the Bosch's they APPARENTLY;

- Bolt straight in (Don't require mods to mount/fuel lines/extra fuel lines to reach bottom of tank)

- Don't have 1/4 tank issues.

I will put the effort in to install a 910/040 if I have to, but is there any need? I don't want to get a 2nd hand GTR pump.

Cheers

Chris

what about with the same amount of power ie 200rwkw but using an aftermarket turbo or high flow turbo maybe running about 16 psi max, would the walbro item still be sufficient. again on the rb20, reason i ask is that im in a similar situation as eXc.

That's where I am at aswell, as I will be using a bigger turbo (rb25) possibly a high flow.

walbro will be fine up to 200rwkw anything over get the bosch,

they really arne't that hard to fit. but if you are going to use the bosch you will probably need to run direct feed from the battery as the current draw is a lot higher than the stocker and may blow the fuse (it did in my car)

why not the gtr pump? mine is doing fine on my rb20 upto 270rwkw

if you wanted a new pump i would go the 040.. my brother had one in his old r33 gtst and never had problems with the quarter tank issue.

I'm considering ripping my bosch pump out come summer as bosch pumps sound crap once the weather warms up.

I'll be dropping a new pump in so it will most likely be something along the lines of a tomei/nismo internal pump. They are both around the $300 mark. I won't go a second hand gtr pump as second hand really isn't worth the trouble when it may get a little lazy 6months down the track.

Where did you find that price? They have all been $400 + when I looked.

2nd hand - Same reason I dont want a GTR pump

I ran a walbro at 240rwkw and 16psi no problems on a hiflow turbo and 555 injectors, pump handled it all fine.

Yes, i've since sold and installed another brand, but I'm setting up for 270-300rwkw, thats a fair difference.

As did my "mint" GTR pump, had a workshop put it in, had been working fine for about a year until a couple weeks ago when my car started running very, how can i say, shit. Turned out it was the GTR fuel pump so i replaced it with a in tank VR commodore replacement fuel pump ($95 brand new, all i could find at the time) put my car on the dyno again to check A/F ratios and they were all sweet at 160RWKW

i picked a Denso high capacity pump that flows around 300 l/h. its a direct fit and its not as much hassle as a bosch pump with the messing around with the intank brackets and that. it cost me around $250 if i recall correctly

its good for around 300 rwkw.

anyway just thought i would give you another option

cheers

      new 1.5 LSD issues/concerns

      sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving.

      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?
