Hello

Hello I have a rb20 det with 25 turbo, soon to get a bigger turbo.

With me going to bigger injectors, I was told that I will need a aftermarket fuel regulator.

Any brands better than the other?

I am upgrading to 440cc or 550cc injectors.

Is it best to get a aftermarket fuel rail or is the stock one fine?

I suggest you get a Plazmaman Fuel Rail and also a Turbosmart FPR3000 and then twin feed the rail. You'll need all the fuel you can get.

Whilst you're at it.. get an After Market Industries surge tank with twin Walbro 450L pumps.

Hey dude,

If you are not going to be helpful stay off the post.

I am though? a good fuel setup is crucial for any performance car.. also future proofing your setup so when you do get the RB25DET NEO in with a GTX3576R you're all sweet.

Also I heard the search function at the top right hand side corner works well too.

Mike,

I found this for you

http://www.sau.com.au/forums/topic/408500-will-i-need-an-aftermarket-fuel-pressure-regulator/

Most cases, the stock reg will be fine unless you run an aftermarket rail but with new developments Scott Fisher (Scotty's customs) has developed an adapter so you can get the stock reg on an aftermarket rail.

I'm not sure if it will suit RB20 though

I myself ended up going Nismo reg because I thought the stock reg was shitting itself (turns out it wasn't). Tuner said stock reg would have probably been fine too.

Hope this helps

I think a surge tank etc is a bit excessive to just go jumping to when short term goals are so small

I have been looking on the internet but not finding what I needed to know.

He's just playing with Yoshii, because he's sick of Yoshii asking questions that already have 5000 threads.

IF you don't like it, don't respond.

If I don't know anything or can't find answers I'll ask.

If you don't want to help say off of my posts.

Your stock fuel reg will be fine.

If you are so crap at searching I suggest you just spend a few hours reading the various subjects on this site - it could save you hundreds if not thousands of dollars.

Also if you are planning to get an RB25 (preferably Neo) engine I also suggest you don't spend any more money on your engine but just save up for the RB25.

Good read.

Learned some new things.

So I will make sure to confirm everything with the tuner.

Car is old, want to make sure it has the additional support in place if needed before I go adding bigger injectors, turbos, etc and boosting up more.

Not going to get into a childish forum sprew with you.

You don't know what I found. I asked the questions I wanted to ask after searching.

I am learning to use what i have now.

Its not going to cost that much to get over 300hp in my car. I might get to 300 or 350, etc and not want to change engines or get higher hp.

Upgrading injectors, turbo(which is on its way out) and tuning for that is not going to break the bank.

Here in Japan, the cost that shops charge to change out engines is the same as getting a GTR. Ive already been through it with shops asking about prices. If I buy a 25 or Neo 25, or 26 I am not just going to put it into the car unless I know its good and runs. Otherwise its getting refreshed to make sure its not a piece of c.

If I do put a different engine in, it will be done with the help of people who know how to install the engine. That means finding people, wiring things up, finding a ecu, tuning etc. At this moment I know of no one who can do those things, mainly the wiring and other things with 25 into a 32.

At this point I will simply up my hp some with bigger injectors, bigger turbo, tuning, it is a much cheaper option right now.

Things are very expensive in Japan. Parts for rbs and engines have gone up in price due to the importation of many of the items (r32's) into the states legally now. Engines that are not a piece of c.

Once I drive at least 300hp with what i have, then I will decide on changing the engine or not while I am saving for the engine change.

If I come across a 25 or 26 for super good price and it runs, of course I will get it sooner than later.

25 is not the Be All of engines. I read how people like Roy other people are perfectly fine with their 20's. I haven't cracked over 280-90 hp yet. So I have no idea how it is to drive a car with that hp.

I have GTR injectors, if I am going to use them I will get them cleaned and flow tested, but they came out of my friend's gtr, they run but will do the cleaning and testing to be sure.

Have access to a gtr resister pack and I have the info I need to wiring it to the 20's loom, and a friend who can help who has done it before.

The injectors were free, so that saved me about 300 dollars for new ones.

Turbo I can have rebuilt and hi flowed for low price, or by turbo that is only rated for about 300-350 hp for a low price.

Have a gtr pump which is dying now, so have to change pumps anyway.

So when ready for a different engine and if I still want one, I will buy it.

/\ I didn't read all that but I remember the first time I drove a 20 I pushed the accelerator through the floor so hard there was calf pain, I hear you though with the price & availability of RBs getting worse for sure, just put a 25 turbo

Yes I know pushing that pedal down.

    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
    • Literally looks like direct port nitrous haha
    • They are in fact just nozzles. They are there only to produce a spray pattern and limit flow. The injector itself is what I use to control flow to the 7x nozzles. My old system had no injector and only PWM the pump. This lead to a lot of inconsistencies, and poor atomization at low pressure when the pump was ramping up.
