Obviously, but it's a cheap upgrade, if you're doing the pump, do the reg as well.

What is the current one the OP's car, 15 years old? +

You don't need a reg. Why change the reg, the factory one is more than fine for nearly any job. Yes the factory one is 15 years old, but they rarely fail and are hassell free. Most aftermarket regs are more hassell than they are worth when in the wrong hands.

Like i said early, the best and easiest choice is a Nismo/Tomei in tank. They are a direct replacement, piece of piss to install and don't have any problems. Their only downside is the cost. The Bosch's are fantastic pumps, they will flow more than the Nismo/Tomei, however they have to be installed correctly, which a lot of people f**k up and then have issues with. We just ripped out an 040 out of my mates S15 and replaced it with a Tomei one becuse the Bosch one wasn't done properly.

Agreed.

It offers no benefit over the factory fuel reg.

It is therefore not an upgrade. So please do not use such words.

Until such a time as the reg fails, and most appear to hang together for 20+ years perfectly fine, then you do not replace it.

That's like saying you should replace the turbo actuators after 15years just because they are old, or replacing the brake master cyclinder.

Just because it's old does not mean there is degraded performance.

I disagree completely.

I put in a Bosch 044 and even with the extra Speedflow fittings and such it still worked out $150 cheaper than the Nismo pump, plus if it goes south it is cheap to replace!

I think it would be good practice to measure the fuel pressure with the new pump and make sure that the standard reg. is doing its job, even better practice to replace it however I need new tyres :D

I disagree completely.

Why though? Lets take it to basics and discuss what an aftermarket adjustable fuel pressure regulator is, does and what purpose it serves.

An aftermarket fuel regulator allows you to bump up the fuel pressure when your injectors are maxing out to squeeze out that little bit of extra power out of them. Most people do this to make the stock injectors go that little bit furthur. They are old injectors and do not like to be squeezed passed their safe efficiency. You are just asking for trouble if one suddenly decides to fail and lean out a cylinder.

When going aftermarket injectors, you pick the injectors size to the power you are aiming for, therefore why go an aftermarket regulator. You will just be running them on normal fuel pressure, therefore the aftermarket regulator is doing nothing as far as adjustability is concerned.

The only real application for one is on large power levels when you allready have large injectors and you need to run them at slightly higher fuel pressure to cope due to the stock one not being up to the task. The stock one can easily do 350+rwkw so there isn't a huge group of people doing this, especially the OP.

Main reason why people buy them is if the stock one fails, or if their aftermarket fuel rail can not use a stock fuel pressure regulator, then yes why not buy one they are cheap in most brands. But most of these people are just buying one because they need a fuel pressure regulator, not because they wont to change the stock one to something that is adjustable.

In the OP's situation, an aftermarket reg would be of no benefit and money that could be spent elsewhere.

Suit yourself. If that is your attitude though, you might as well replace the entire car, every single mechanical piece that operates.

I bet you've not done that, so your own attitude and actions do not match each other.

Practice what one preaches?

Fact is, the fuel reg is either working, or it's not. I've never seen one slowly fail. Once they let go, they let go and you'll know about it when it does.

:D

Mainly with R31Nismoid and most if not all of his statements.

I'm going to frame this, it's hilarious.

Frame away, but make sure the plaque underneath it says.

"I don't practice what i preach, nor do i have any clue mechanically."

To think that something mechanical cannot be built to work over many years without replacement, and as good as the first day it was made... Is naive at best.

I'm terribly sorry but please do not assume what I practice.

I don't need to assume, i know.

No-one in their right mind would replace every part on a car because it "might" be worn without any proof or fact.

Do not have the required resources to satisfy your unreasonable request.

As long as you think you're correct, that should provide enough satisfaction.

If you believe me to be incorrect, I have no problem with it.

I do not ask for unreasonable requests and result to personal insults, would be degrading and a bad example.

      R32 GTR EV? The leaf of the Godzilla's!

      And at over $2 per litre I'm starting to consider setting up a corn mash still and converting over to alcohol and running mine on it !  Up side of that is it all doesn't have to go into the car ! Win win !

      H2 (for cars) will never happen. It's not reasonable for any number of reasons. It's also not reasonable for almost all of the industrial uses that the fanbois say that it will be used for, again for a large number of reasons. There are some cases where it will be good. But, even those will be massively hampered by the economics. The only way that H2 can be economic is if we somehow manage to get from where we are to the other side of the economic-valley-of-death in which no-one can operate. You need there to be sufficient renewable generated electricity to be available so that it is effectively free. Once you are there, you can do whatever the hell you want and hang the efficiency. But until you get there, the ever diminishing value of electricity makes it harder and harder to encourage businesses to build the new generation capacity, and they will simply stop investing in generation projects. (I kinda think there needs to be just government money spent on building the required capacity in a non-commercial way, similar to how the first fossil fueled grids were built, as national-government owned utilities. And probably some nuclear in there to start. But this all should have started 10-15 years ago to avoid the chasm of death that we face right now). Synth fuels will be much more likely, but will only occur is there is at least some renewable H2 production, because you need H2 to do it. And you need stacks of free (or at least extraordinarily cheap) energy because assembling molecules back into fuels is exactly the opposite process to burning the fuel, and the reason we burn fuels is because there is so much energy squeezed into each molecule. So you're somewhat subject to the same economic valley of death problem as above anyway. That is unless people are willing to pay the current equivalent of $5 or $6 per litre of petrol-ish liquid fuels. Can you imagine it? The squealing at $2 now is bad enough.

      This is so cool. Get a dashcam that records audio and hopefully you'll catch it.  Maybe there's a brand or some kind of markings on the back ? Are the pics hand drawn? I love it so much.

      Hahaha yep, point(s) taken. I just like seeing different things and an EV in an R32 is pretty different. I'm not on the EV band wagon, I'm waiting for synthetic fuels or hydrogen personally.
