Does anyone know where I can get a good fuel pump for my 5th gen max. I want more nitrous. Oooaahhaahaa!!!! Also is there anywhere to get injectors as well.

 

I heard Walboro (sp?) fuel pumps are good. They fit the 4th gen, but I dont' know about the 5th gen. Adam (My 4DSC) was asking about it before, but I dont' know if he tried it or not.

Larger injectors? Not sure if they'll do any good if you're idling or not taking your car hard. You'll also need ECU reprogramming to make them work effectively. Unfortunately, no one can reprogram them yet BUT, BUT, BUT..... The Racers Group, or whatever they're called (formerly known as The PROgram), has a piggy back that might be able to trick the ECU.

 

First off thanks for the reply kev I was starting to think that if you asked a question here that you need to ask something about how to rice out your car. Not obvisiouly all max enthusiasts. Any way now that I vented that. I talked to stillen and they said that for 575.00 they would reprogram my ecu. So I am looking to do that right now. Hopefully it will come through. If not I will be looking into a walbro pump or something. Thanks again for the reply.

 

u can take the fuel pump off of an old 300zx TT and it will do u alot of good! dont forget its the same car 2 door and rear wheel drive!

 

Even with the ECU reprogram, you should still get the upgrad on the fuel pump. You need a pump that move more volumn of fuel. The stock pump will only handle so much. What exactly will the reprogramming do?

 

I'm under the impression that the fuel pump for 5th Gen Maximas is located inside the gas tank. How would you go about upgrading it?

 

I haven't looked on the 5th gen yet, but on the 4th gen, if you take the back seat out, there is a access panel to take out the fuel pump.

 

Somebody want to take a look on a 5th Gen and let us know? Also, on the 4th Gen, is the fuel pump inside the gas tank or outside the gas tank?

 

Just spoke with Dave Burnette at Town North Nissan, and he said the fuel pump is in side the tank on the 4th and 5th gen, but he is not sure if they will fit, it depends on the size and fitting of the 5th gen. since its diff than the 4th gen, also the 2002 has a diff fuel pump.

 

I was looking at the 5th gen FSM (Thanks to those who know who they are ) and it looks the same as the 4th gen. I'm be 95% sure that its just about the same, Walbro GSS432. When I did mine, I left the car apart for a week. Sooooo if you really want it take the pump out spend some time looking for one that matches and make it happen. You will need a new gas tank O ring seal from Nissan.

 

Where do most ppl buy the Walbro from? and is it the same as the Z or better. I guess what I am asking is what is the specs on the Z compared to the Walbro, and compared to the stock pump. Thanks

 

I'm also interested in this data. If anyone can help, please do. Thanks in advance.

No info to FAC-Q with.

 

use the BLOWER

 

Ah man... you too?
The closest blower I can get is Jane's hairdryer.

 

yeah I figured I would join the bandwagon, and pick you as the one to buy the S/C, we all know how much you envy me

 

 

Lookie heree for info on the walbro's

I can gaurenteeeee that the 255lph high pressure pump out performs the 300zxtt pump. I cant prove it but I'd bet my new hair dryer on it...

 

So you bought Steve's motor? That was a great deal!

 

Yea, but my divorce wont be such a good deal though...

He built it up for 8psi with a 125hp profogger nitrous set up, forged rods and pistons. I'm thinking more than 10psi of boost and 50hp nitrous. I just got to figure out the fuel issues. I'm buying some TT injectors and mabye the Vortech Super FMU or Apexi AFC. An inter cooler and oil cooler would be needed too, along with Boost, Oil Pressure & Oil Temp Gauges.

What dumb luck to stumble upon that deal as early as I did. I'm just hoping the install and all goes well. Ive been preping my garage and have a motor hoist lined up. So with a lot of wrenching I'll have a SC/NOS Maxima. Steve said its capable of easy 12's... Well see!

 

Sorry to hear about your divorce.

Blower and happy juice? You've got the engine to do it with, so good luck with your project. Vortech Super FMU, eh? Hmmmm.........

How are you going to deal with the fueling for the TT injectors since your ECU isn't reprogrammable?

 

Thats if she find gets ****ed about me tearing the motor out!!

The Vortech Super FMU is like an adjustable fuel pressure regulator for boosted motors. It will let you set the idle fuel pressure as low as 20psi, stock is 33psi. So If I set the fuel pressure lower than stock at idle it should compensate for the larger injectors. You can also adjust the max pressure under full boost up to 90psi. You can also adjust the rate at wich the fuel rises relative to the boost level. Its made for situations like this. If that dosent get it I'll throw an APEXI Super AFC on top of that and it should work fine. Steve did send me his 96 ECU so I could just swap over to that, but it kinda PITA to do it. and JWT wants $550!! I have plenty of patience with this kinda stuff so I'll go with my own tricks for now...

 

Ohhhh.... hehehehe


Interesting. That FMU is $278.30. Not too bad I guess. The theory you have sounds quite interesting. Now you've got me wondering... thanks for the idea.

 

Matt what have you gone off and done now. Boost?!?!?! I thought that you were just getting intake heads. ???

 

He bought a VQ32DE-S (supercharger) from Steve in Philly. That's not a typo... VQ32DE
