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

AH you got the denso 500hp rated pump....thats what Im going....Ill try to get the part number tonight...a workmate of mine has one...

if you can get these for close to $250 you are doing well, they are a top pump...

and as stated direct factory fit, took about 15mins in same guys silvia...

    • ok so if i wanted to go 18's i would go for 8's  in front 30+ or 32+ off set at front and the back 9 would be ok? what offset should i aim for.. then can i do some  hunting for wheel rim choices..    If i get this - will this fit all around: Size: 18 x 8.5 +37 - n what tyres size tyre should i get for front n back?  
    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
    • Hey mate,  I have a set, one is slightly damaged but wont be noticable once installed.  Shoot me a message if your still after them 
    • I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
