Almost done guys. Quick question.

Would a walbo pump support 500hp at max. Im looking for a fuel pump thats intank but not to expensive.

Was looking at walbo GSS342.

I guess i should ask what does the oem pump support as well:unsure:

Thanks in advance

I have a Walbro GSS341 255LPH in my tank and they are rated at 500hp but I have only run mine to about 300hp - after that I got a surge tank and another pump so now the Walbro is just a lift pump. I have my doubts that it wold be work at 500hp but if you get a brand new one and directly wire it with a relay to get full battery voltage you would probably get pretty close. The next one up is the 400lph pump which costs about 50% more and is rated at 750hp. I would doubt the stock pump would do the job and of course being quite ancient now it could fail at any time.

Oh, don't buy the 400Lph, they are not a great pump. Get the 416Lph e85 one. They flow around 450kw on e85, probably near 600kw on petrol.

The 255 will flow 300kw on e85 and around 400kw on petrol, (all at the wheels.) depending on pressure.

The 416lph is a drop intank pump. Do they fit in the original r32 gtr fuel pump location. Or is there some sort of modification thats needed. I know the 255 in one of my silvias were a perfect fit. Walbro provided all the necessary parts with the pump.

Thanks ill look up the 416lph.

The GTR has a completely different setup, but it's usually nothing a stainless hose clamp or two won't fix. More important is to work out the sock hose length, as I am always seeing low level surge issues with GTR pump installs.

The stock GTR pump would probably be fine if it wasn't so old.

      R34 GTT idle problem

      By joshuaho96 · Posted

      For me at least the reason why it bothers me is because it's indicative of a deeper problem. And that will nag at me forever. Especially because I have tailpipe emissions testing + evap leak testing every 2 years.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      WELP. I went to the track, and I suppose it went okay because any time you can drive home is okay. You may notice the car is not on the circuit in this picture. It was about 35C day out in Benalla which means the track was approximately the surface of the sun, probably. Good things, car did not overheat but it _was_ warmer than when I had done track days in similar heat before, I think, I'm not sure - I can't quite remember. Coolant got to ~105 via the ECU after 20-30 minutes of belting it in said heat. Oil got up to 145C in one instance which is pretty crazy due to oil cooler. Pressures were fine. I seem to remember this not getting quite so high before the vents. More HMMMM'ing to be done. On the subject of HMMM'ing, can anyone identify the sounds in the video below, you will know which ones I mean: https://www.youtube.com/watch?v=uj3BkI2cbTc I included some 'normal' sound as a reference for the first minute or so. The microphone in this instance was where the license plate is. It stopped working later in the day which is why my "best example of a lap video (not produced)" had internal audio - Isn't hearable from inside the car. I don't mean the chirping of the un-bedded/badly bedded track brakes which you can only hear while braking... Thoughts, brains trust?

      Did anyone here buy the crashed N1 R32 GTR at auction?

      blame old mate Hawkins for that one  I remember way back in the day the japanese didn't want them either... they always assumed a race shell would be thrashed. We found a few when looking for an R34 GTR for the Whites to drive in Targa Tas back in 2002.

      R34 GTT idle problem

      By silviaz · Posted

      I know it's probably not going to cause any major engine issues. I just had a more generic concern that it's technically not running right (I guess this means the rpm is not sitting where it technically should be) Though the other thing is, it's that my steering wheel is shaking at 1,100 rpm at idle until it gets warm (seemed to happen after I tightened my alternator belt, will be testing the alternator soon).

      I mean, what's the concern here? Higher fuel consumption? FWIW my idle sits at around 800rpm or so as well. And yes, it runs fine, idles fine and there are no issues as far as I can tell. I don't quite see the problem.
