nope, I had one, leaned out at 280rwkw and above.

at 300rwkw, the afrs wouldn't go below 12.8:1, even with the injectors completely maxed in the power FC.

Have you seen the flow chart? Watch the blue line below 60psi.... Terrible!

mine saw the end of its performance @ 240-250rwkw

Walbro's are a mixed bag.

Sometimes they work, sometimes they dont... i wasnt even running upped rail pressures over normal conditions

There are FAR too many threads now with people and Walbros who have fuel issues.

I simply dont trust them. Have used Bosch for the lasf 4 years since.

mine was ok, just ran out of flow.

Remember the ratings -

Walboro 255 is 255lph at 40psi

Nismo 275lph is at 275lph at 70psi (What I have now)

Nismo is a perfect pump, drops straight in like factory, has a factory bracket, hoses and plug etc. I'll never touch a bosche.

whats terrible about it? i dont look at fuel flow graphs often but it seems to flow a fair bit below 60psi? its above 60 that it really drops off. and why does more pressure result in less flow? i thought mroe pressure would mean more flow?

yeah well think about it - rail pressure is 42psi + your boost (maybe 12psi?)

Thats a total of 54psi fuel pressure needed to drive the injectors. I don't know about you but thats putting the pump on edge and I wouldn't risk it.

Its a POS.

Actually, it was meant for NA applications..... Its pretty obvious..

I am in the same dilema but I want something for 400-440wkw

My opinion is.... two walbros!!! Two walbros are cheaper than one 044! Here in Greece my mechanic said me that he saw many 044 to broke.. and aeromotive to broke...!! So he said me that with all pumps we have the danger to broke!

They broke either if you stay without fuel or if you leave the fuel for very long time (one aeromotive broke with the last way)!

If one of your two walbro damaged the other will work :D

So more safe!! :P

As I understand here in australian you don't use walbros... Here in Greece all people untill 500 fly hp use one walbro!

All are happy untill 500 with one walbro... too much scooby, evo etc!

After 500 you need a decent fuel setup as many people here told me what to do (surge tank solution with total 3 pumps)

    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
    • When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?
    • Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.
    • If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
