Hey guys I am installing a Walbro fuel pump, I believe this is the fuel pump used in the cosmo 3 rotor. Now is this a good fuel pump? how much horspower can it compensate?

Many people seem to be using it with no problem but personally I'm a little leary of the price. BTW, the 20B uses a Nippon Denso fuel filter, not the Walbro.

anybody else and their thoughts?

I use the gss341 walbro (hi pressure) it's supposed to be good to about 450 Hp, I think

Isn't the oem supra fuel pump the best bang for the buck?

Supra is the biggest pump that will fit in the stock location without mods. Yes its a good deal. I bet you can find some used on the supra forum.

I had a Walbro for about 5000 miles and switched it out in favor of the Supra OEM at the advice of Dave Barninger of KD Rotary. I've heard of quite a few failures of the pump (take it w/a grain of salt), but my main reason for switching was this:

The Walbro is *smaller* than the stock pump. Of course, bigger isn't always better (ask Spyfish's girlfriend, she loves his little pipper ), but when it comes to a fuel pump, I'm not ******* around. I'm not blowing another motor anytime soon if I can help it.

The Nippondenso pump that RP (rx7.com) sells has been tested to be good for around 500rwhp. Many people have told me it's the same as the oem supra one. Regardless, if it was my 3rd gen, I'd stay away from the Walbro.

Hell, if you don't wanna listen to me, you can buy mine--accepting offers now

My Walbro GSS-341 has been in my FD for about 10K miles and I've had no problems.

More surface area means better cooling, so there are some benefits to larger pumps, even if they don't outflow the smaller ones at some fuel pressure levels.

Bosch vs. Walbro...

LOL--Jimbo, I just noticed the "Pastor of Muppets..." that's some funny sheee-it, you **** gobbler you

jimlab

YZF-R1 accused me of being the "Master of Puppets" at one point, so I changed the text just to mess with him, but then switched it to "Pastor of Muppets" because I felt it was more fitting since his rants are usually (well, always) religion-based.

will the supra fuel pump be just as big? and is $210 a good price for it?

I believe (someone correct me if I'm wrong) that the "Supra" pump and the Nippondenso pump sometimes called the "Cosmo" pump are one and the same. I don't have part numbers to corroborate that, unfortunately, but I have heard others say it also and I have no reason to doubt it.

If that is the case, the Supra pump is neither as large as the Bosch pump nor as small as the Walbro pump, but exactly the same size as the stock pump. When I installed my Cosmo fuel pump way back when, we could not detect any external difference from the stock pump. Trev and I conducted our own unscientific flow test, running each pump from a can of fuel into another can at full 12V for a timed period, and the "Cosmo" pump did indeed flow quite a bit more fuel than the stock pump. So in it went.

Anyway, is $210 a fair price? Hard to say, but that sounds about like what I paid for my Cosmo pump. The Bosch pump is $200 from Doug Rippie Motorsports (www.dougrippie.com, go to the fuel section) and that's about the best price (and the correct pump with the bottom inlet) that you'll find. The Walbro can be found for about $115, give or take, and about $125 with the RX-7 "install" kit. Either one is an easy install but not necessarily a direct drop-in. The Cosmo pump I had was a direct replacement for the stock pump, so the Supra pump may be also.

Works now. It had a comma (",") appended to the URL because I didn't use tags.

Is someone using the supra pump that can attest it is a drop-in replacement? or does it require some modifications?

wptrx7

i believe goodfellas above said he had it, and yes jim the site does work now, thanx.
