Matt, not sure how well a high alcohol fuel would go in a car that is driven as often as yours isn't.

Alky loves the moisture.

Will, that's exactly what Shaun & I were talking about yesterday.

I've only just learnt that E85 exists - been hiding under a rock. It might be a case of switching between E85 and pump 98 tunes, I'm not sure. Example: in goes a tank of E85 for some fun, run it low, in goes a full tank of pump 98, switch tune over to 98, fuel system has mostly 98 in it and can sit in the shed till next time. It seems good in theory. Then again I could be way off - Martin would be the man to confirm that one.

Obviously the injectors need to have enough capacity to support the E85 and fuel pressure will need to be spot on etc.

One thing is sure, we'll certainly do a Martini 110 tune.

Drove the car yesterday and was able to use full throttle for the first time in about 2 years! It does in 3rd what it use to in 2nd. I like it.

I notice someone mentioned Skylines Downunder in this thread. Good old SDU. I can still recall registering on SDU when it had about 100 or so members - in about 1997 or thereabouts. Times have certainly changed!

Anyway back on topic; Can't wait to see what a tuned, exhaust upgrade, boost increase R35 GT-R can achieve on the drag strip. It's only a matter of time till people start run high 10's with a mild R35. Events like Targa West and Targa Tas are also going to be interesting as more R35's start popping up.

Ohh, didn't even know that! God, Nissan know what they're doing then hey. Way to destroy the hopes and dreams of others. No big single turbos for the new GTR's for a while then. :)

Nah won't take long at all for the tuning companies to make some T3 outlet style exhaust manifolds to bolt all the normal turbochargers to - I would be very surprised if someone hadn't made one already and has it in testing pending release for sale to the general public. Remember that the Yanks have grabbed onto marketing of the GTR and have already started throwing money at development - not to mention all of the decent Jap tuning houses have had one for 9+ months now.

the turbine clearly looks integrated but nothing stopping the compressor housing from being detached by the looks of things......don't know where your going to find a suitable replacement though. Like Andrew said, pretty soon you'll be able to replace that whole setup anyway.

And you can only thank the good son of rajab above for that.

Hopefully this integrated approach will stop some of the general public turning these engines into laggy slovenly performers through the midrange with badly thought out turbo upgrades, which has been happening in the RB world for years. Amen :)

Jarrad when they finally do come up with an aftermarket replacement for the 'V' engine (which they will), it will still be a dual setup, unlike the inline RB's

Another way of looking at it.....

With the stock GTR IHI RHF55 turbochargers each good for around 35lb/min airflow with reasonable efficiency and using boost of around 1.4 bar,

The answer to a properly tuned stock power output would be close to 370 - 390kw at all four wheels without changing the turbines.

Now, correct me if I am wrong here, but that would be more power than 99.9% of most Skyline owners would ever get close to having, or even possibly dreaming about. Nissan should be thanked for using such capable turbochargers on these engines in the first place. They make even the 34N1 turbochargers look like jelly wristed pea shooters in comparison :closedeyes:

thats a good way of looking at it.... and a good analysis of the 34n1 turbos lol...thats decent power for sure.

Look its a forum, anyone can have an opinion - but heres the facts....

R35 GTR Stock

0-100km/h - 3.5 sec

0-400M - 11.5/11.6sec @ 120-122mph

Now to get this pace from an R32/33/34 GTR you will need -

TD05 kit/GT2540 turbochargers or similar running 1.5 bar boost

700cc+ fuel injectors

Upgraded fuel pump

Programmable management FC or similar with a correctly carried out tune

Front pipes

Full exhaust system with cat removal

Upgraded twin/triple clutch

Possible intercooler upgrade

and be prepared to build an engine for it in the very near future...

as well as being in a constantly harrassed and defectable car :closedeyes:

This isnt a guess. We have done our fair share of GTR modification over the years.

Nissan have done a very good job of building a genuine supercar that thankfully DOESNT need a bucket of cash thrown at it to make it go like it should.

That is the true value of R35 :)

Having said that the rb is late 80's technology and i believe it did very well to last this long....time to step aside i think, although the R35 is yet to be proven 100%. Time will tell...i have complete faith.

      Starter motor replacment teeth count.

      By oHBoy. · Posted

      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.
