Boostworx or Road & Track Dyno can both do the job, theyre both in Cavan too.

How many RWKW are you aiming for in your car?

If it is anything upto 280rwkw i would recommend going down the Walbro road, but make sure you buy from a reputable dealer.

If you are set on going the bosch out north i would say Boost Worx and out south i would go to Southern hitech.

There may be some people on here who may volunteer to do it for you also.

You are probably looking around the $100 mark as you have to modify the craddle and if done correctly they will double earth the pump.

ok but will the walbro still need to be rewired?

Def not chasing more than 280rwkw. Where do you recommend i purchase one from, just jap?

Live down north east so boostworx sounds the likes if it needs to be rewired and 100 bucks def sounds reasonable.

what is your main reason for upgrading your fuel pump if your not chasing any more then 250+rwkw??? as far as i am aware the stock pump will work fine for up to 230rwkw?? correct me if i am wrong please...

i had mine done by boost worx together with a whole heap of other work so i had mine done for pretty cheap....not sure if they had to rewire it or not

Ahh well it is a 14 year old pump so just for piece of mind really, just wanted to get it done before i get the car tuned, would probably have to do it down the track anyway so why not now?

Did you got walbro?

the walbro is a drop-in-cradle replacement, physically its smaller but comes with a rubber surround that takes the diameter to the same as the stock pump

there is a wire and plug supplied which needs to be wired up but its a small matter of using two solders or braid, then it should just plug back together

there is no secondary earth on the walbro pump but its not required, esp if u have a pfc or are doing the 14v pump mod or bypassing the fuel pump regulator

I have a Bosch 040 but i think its mounted a tad high....needs to be readjusted

if you dont have a budget limit then i suggest going a nismo pump.....much better then either walbro or the bosch but a touch expensive but they fit in without needing mods from memory

also try looking up through the traders here on SAU....they do have genuine gear

[nicr4wks]

I purchased a Walbro through petroject, after spending more times than I can count on the side of the road bashing the fuel pump cover trying to get it started again, I now have a muchly appreciated 040.

[Krishy]

have heard that bosch are a better pump in comparison to the walbro units.....but cant say that i have experienced it personally....only ever used bosch

[Madaz]

yeah i have a bosch

[dark.sky]

Ive got a BOSCH 040, mounted/modded it myself. I got told to go for 3mm off the bottom of the tank, so thats what I did

[jrm]

Could always go Nismo - direct drop in ... just probably more money than you want to spend ..

(disclaimer - I had one fitted to my R34 on the weekend - was stunned how easy it was to install - thanks RubyRS4 )

bosch is a solid reputable brand

most of the problems with walbros (as I see it) are the non genuine knockoffs that fail or don't flow to the required specification.

The walbro high volume pump does around 255lph @ 3bar if I recall correctly which is slightly more than a stock gtr pump, however the bosch 040 runs a bit less (240lph) but it pumps it more consistently.

Only downer with the 040 is the need to modify the cradle - top quality units tho.

I ended up with walbro just cause I needed one right then and there and Boostworx had one in stock - seems to do the job!

Easy? I was the one crawling into the car fitting it and sniffing fumes

Nah, it was easy to fit. Easier than when I fitted my Walbro to the Stagea.

How about "straight forward" instead of "easy" ...

Besdes, you seemed to enjoy the fumes

[jenkies]

id agree.. i found it was a 40 min job with a few beers and patience.. do it for fun man

[R33 Sleeper]

thanks for the feedback guys, here's what im thinking.

since im getting a workshop to fit it i think ill got the bosch, cant justify spending over $400 on a direct replacement pump.

So leaning towards boostworx, has anyone else had theirs fitted there that can tell me if theyre able to do the higher voltage rewiring aswell?

[Madaz]

boostworx can do anything you throw at them Shaun knows his shit

[Damo_R34]

boostworx will do whatever you want to your car.
