Which is better Walbro 255 or Supra TT fuel pump?

 

Get the BNR R33 pump

 

well I have both, I have the supra TT pump in it now, but I have a walbro from my gsx. Just interested to know which one is better out of the two. I do miss the nice soothing hummmm from the walbro.

 

Go with the supra, OEM quality, drop-in, and totally quiet.

 

But is it proven to be a better pump?? I like the humm, so it doesnt matter to me. I just want to know what will perform better.

 

If you have both try both.

I duno what to tell you then. I have neither.

 

I've never heard the Walbro hum in a FD, I have in other cars though. maybe the FD's tank is pretty thick and insulated or something.

They are both fine, use which ever its not going to matter

If the Supra pump is doing what it is supposed to do, I wouldn't mess with it. BTW, most people would rather not hear the fuel pump.

 

I'm running dual walboro's and don't hear the hummmm

 

i prefer walbro

 

ok, but isn't the Walbro 255lph too small to support a single turbo?

(lets take into account that is what he has, may not be correct)

 

Well when the time comes and i need more fuel ill just double them up. Nothing wrong with that right?

 

The constant whine from the Walbro 255lph HO pump that I used to have drove me crazy. I vote for the Supra pump.

I couldnt ever hear mine

 

Just read up that there are two versions of the Walbro 255.
GSS307 [255 ltr/hr]
GSS340 [high pressure 255]
They put a different pressure-relief spring in a standard 255 ltr/hr pump that raises the output of the pump above 50 psi of fuel pressure._

 

The GSS307/GSS340 are comparable to the GSS317/GSS342 that go in the Hondas. The high pressure pump has significantly more power above about 50 psi.

I've seen this graph with a Supra TT pump and it's pretty comparable to the GSS342.

I was about to install mine today. It is stamped GSS431.(ebay $90 shipped!) The chart is showing that it is identical to the GSS432, but they cant be exactly the same because of the different stock numbers. Anybody know?

 

don't want to **** on anybodys thread, but wasn't there some noise a while back about the walbros failing?

 

I mean it is stamped GSS341 instead of GSS342.

 

I think one is just a newer #. They were made from like 93 to 2000, right?

 

I have one for sale if you want it. The supra one.

 

The flow ratings of both the supra and the walbro have been posted before. The supra flows just a tad more.(260lph?) So if you have both, keep the supra pump IMO.

As for the walbro question on a single turbo application, I believe if you're going with anything of decent size(t04s on up) I'd go ahead and at least try to find a used supra pump. Or you could do two walbro's.

As for the question of walbro's failing, I believe this has been discussed and it probably would be easier to search and find the answer.
