will be close/borderline to being maxed.

if you were under i would say ok, if you want a solid 300+ then maybe get a 044 bosch motorsport pump, good for >400rwkw.

see how it goes, if it leans out even with extra injector duty cycle, will need to upgrade.

Well Snowman ran a stock R34 GTR pump i believe with 350rwkw

Really depends on the pump, age, and so on.

Only way is to either get the tune and go off how the AFR's, fuel pressure looks... of flow test it. Although flow test @ normal flow might not show up something that wouldnt otherwise show up until pressure rises

well my mate bought a brand new gtr fuel pump and made 412kw with a t04z

Yeah stress an old part - why not, fuel isnt important....

Bosch pumps are cheap, unless you are saving every penny just get one, then you wont have to worry

Very true, a good GTR pump will do over 400kw @ wheels.

^^ 100% Agreed - why not just upgrade it now?

They arent super expensive and at least it gives peace of mind it will handle anything you throw at it... a few $$ spent now could save alot more $$ spent sooner than expected.

l made a post regurading the same question a few months back. lets just say l was mocked by some dicks on this site even thinking of pushing that much power through a GTR fuel pump. Now l know l am not the only one who has a GTR fuel pump pushing beyond the 300RWKW mark, makes me feel a little more content with my current setup.

[N1GTR]

It can be done, has been done in the past and will no dount happen again in the future. I just dont see the point (like many others) of running the risk to save $50 on a fuel pump

[R31Nismoid]

If the pump has only done 40,000 as an example it should be fine.

When it fails, replace it

Stock turbos are more of a danger than the fuel pump.

And hell, its not like Bosch pumps never fail even 1,000kms outta the box! Everything has some risk...

Ive got a stock R34 GTR pump in my car made 285kw with no signs of it even being near maxed

cheaper than an 044 to

Hey I'm in the camp of people that would rather not take the risk, and am looking to upgrade.

However, after reading the FAQ/tutorial thing about the bosch 044, it is clear that it is far from a bolt-on upgrade. I have been looking at an alternative that will just "drop in" to the existing in-tank cradle setup (I would rather pay the extra and not worry about the hassle of modifying things or worrying about the hose etc)

So far I have identified the nismo pump, which is about $440 plus post; also there is a sard item sold by JJR that is $700 or something, allegedly that bolts in. My question is:

1) can someone confirm the nismo item is a bolt in, no mods required (r32?) What about the sard?

2) are there any others that are better priced and drop into the existing cradle?

Go the Nismo/Tomei drop in pump.

Its the easiest, most reliable pump replacement option.

just dont run e85 or your new nismo pump will die a ugly death....

and maybe your engine as well

LOL yeah, I didn't drop $ ,000's and $ ,000 on turbos, intercooler, drumps, zorst to attempt to save 5c a litre on dodgy petrol and get 30 pc worse mileage! I just run it on vortex 98, seems pretty happy.

Seriously, guys, thanks for the help, I was about the buy the bosch until I read the write up and was like "um, not for me thanks" so will go the nismo (had heard of the tomei but didn't realise it was the same thing?)

GTR pump in good condition is ample for 300 or even 350rwkw. but if there is a cloud over it's reliability (ie old R32 pump) then it can be worth replacing. I've had one fail before at 270rwkw. it didn't cause any damage when it failed but it was a pain in the arse. bosch pumps are ok, but the nismo/tomei pumps have been the most reliable in my experience but they may be just because they are a true direct fit pump where as a lot of the bosch pumps fail due to incorrect installation. you eliminate any chance of that with a nismo/tomei pump. you would have to try really hard to fk up an install of one of those.
