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.

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

: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.

      R32GTR R200 reverting from Nismo centre to stock

      I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.

      I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.

      It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...

      I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate

      Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
