Standard boost is 0.8bar per the 32 workshop manual.

THanks duncan. So preety much the turbos are already at their 80% limit then.

I was chatting with hypertek las week and i told them i want an everday driveable car with at least 250kw@wheels. Ohh I dont think i mentioned this the car ive got is the 260rs. I just got the car not long ago thats why im asking all these basic questions. Pardon me.

Anyway they said the power i want is achiveable only with the following parts :

1. Full echaust system. Currently i have everything fitted except for the extractors (looking for 1 and 3 : Dump pipes) the rest of the exhaust is 3" as well.

2. adjustable cam gears. ( In transit)

3. Drop in k&N filter

4. Power FC with boost controller.

5. HD clutch.

6. Higher boosy didnt specify at what pressure.

This will roughly get me there. The main problem is are the urbos. The std turbos are ceramic which i need to change to a ball bearing type with metal fan. So i though about it since im goin to take out the turbos when i fit the dump pipes and the extractors might as well change the tubos as well.

Now i dont want to mess with having to change the fuel pump and injectors , water pump upgrades and oil pump ungrades. So i was just thinking of geeting a R34 GTR's stock std turbos whack it in and run a higher boost.

Will the R34Gtr's turbos bolt on directly onto the the 260rs? How much more boost can i gain from it? What other type of turbos will fit onto my car? Like a r32 N1 turbos?

Finall thing where can i get a specifications for the different turbos ever made for skylines? What which model is interchangeable to which? Like an an example which turbos will fit my 260rs? And the specs for it/

Thanks for the help guys.

Cheers,

Yudy

yeah look turbos are going to be a problem getting to 250 :laugh: injectors, fuel pump and and afm will be close to their limit but OK with a safe tune if they are healthy.

I'm pretty sure all of the stock turbos are going to fall short of 250, 32 (or later) n1 can make it, or hks gtss, high flow standard etc etc

Unfortunately I am not sure about the 260rs engine bay, although I'll be interested to see how you go for a future project :rofl: As far as GTRs go all models take all the same turbos, there are heaps of low mount standard manifold options, but highflow standard would be the cheapest if thats all you want.

260RS ....the same motor as the GTR in that year.....What year is it...?

If you have a 98 and up they are the BB type.

If you have the ceramic...

GO

air mods,exhaust mods,computer and boost controller,N1 gtr(300Hp each turbo's)

This should get you to that figure.

But after you get use to the power you will not be able to push these turbo's much further

Sorry guys been busy these couple of days.

Well i forgot to tell you guys its an S1 98 model. i have been told that the stock turbos are steel not ceramic and i can run with it. with bosst to up about 1.4 bar. I dont know the durability factors on the turbos if ran at that boost.

So heres the current ides . im not looking for big powers if not i will get too michevious with it. If you guys know what i mean. Itchy feet and feeling heacy footed too!!.

Anyway heres the list :

1 Power Fc w/ boost controller. (either Apex ones or the HKs v pro

2. AFMs

Will suck it and see how much power i can get. I have been under the guidance of a friend of mine who recommends me what to do. Cos i got the same car as his

But im itching to get the R34 N1 turbos but to think about it if i get the N1 turbos i will probably need to upgrade the fuel pump, fuel reg and injectors. But i think i will wait But wat do you guys think?.

Hello again.

If you like them buy them, don't get petty with information.

Just look at the results people are getting on stock bits and after-market turbo's.RB 26 Turbo upgrades.

You will find you can get these results easy without injector or fuel pump upgrades.

A goodtune and computer with great air flow(INTAKE and Exhaust)

You could sell the turbo's you have, and get some N1's if you like.

With a car like yours you should do the Turbo's.

I have a set if you like i could sell you them...They are Garrett and are bolt on/no modes.

New in a box.

PM me if you would like them.

Cheers

Tekin

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      Mistakes were made, my R34 Story

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      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.
