Hi guys,

so buying qll bits i need for my upgrade and what is left is a tubonand injectors.

turbo will be a hybrid bolt on build by uk company.

 

re injector, they cost around £600. Alternative is r35 gtr injectors and reading numerous posts it seems they are a straight fit but some say you need to change an o ring. Can anyone share their experience on this?

is it a straight fit?

 

i see lots of sets going for £200 sexond hand and also few set of either bosch or denso at £160 for 6 injectors brand new. Is it too cheap to be true / good quality?

if i fit them in, considering my original ones are 370 cc, would the car run at all for me to drive to dynonplace?

I think answer is no as it will flood the engine with fuel. 

So my second question is if i fit it after installing my link ecu  with base image, could i just go there an change the injector size so it will let me drivr it to the garage?

You want to buy ~1000cc (or more like 1100cc these days) Bosch EV14 based injectors from a reputable supplier.  Get the right length ones for the Neo, with wiring adaptors.  viz https://www.injectorsonline.com/au/fuel-injectors/nissan/rb25-neo.html

You're looking at ~$100 ozzy each.  Not 100 pounds each.

And no, you cannot fit massive injectors and drive it to the dyno.  Get them fitted there.

And do't buy injectors from random ebay shitters unless you know the ebay seller as another vendor elsewhere - like, I'd buy from injectors online** (see my link) on ebay if there was a special or something.

**or any of several others.

R35 injectors are a waste of time, stop being brain washed by the stupid Americans.

Get some nice 3/4 top feeds, in the right size and be done with it. Make sure the injectors are 3/4 length NOT 1/2 length with extenders to make them 3/4 as they will not work!

Some suppliers say they "fit" but really they don't, I learnt the hard way from reading way too much internets. Enjoy the read here:

thanks, question I have is one of the tuners I spoke to was saying you can't fit a much larger injector than what the car needs. so for instance if you fit a 1000cc to a 400hp, the spray pattern is differnt and can run rich and die in traffic lights by flooding engine.

 

not sure if that is a correct statement but purely what I was told hence checking. it doesn't sound right to me as you can tune the duty cycle but again not sure if the duty cycle is at 10%, what will happen. would you end up with uneven spray ....

 

 

re injectors you suggested, are they a straight fit with a need to do the wiring only ?

so if I read correctly in injector size is 3/4 inch or 1.92 cm for rb25det neo ?

This is true of old school injectors but not the better injectors for sale now.

i looked up the bosch injectors, unless I buy it from AU . it is much more expensive in the UK.

 

Almost anything you buy here is twice the price. an extreme clutch and flywheel did cost me £1k in gbp which is around 1.7 aud.

 

can't assume it will be that much in AU. injector dynamic is quite respected and well known here but pricey . has anyone used them ?

how about sard?

^ What he said.

Follow Dose Pipe's advice - 3/4 is not a diameter or a length.  It is 3/4 of full length injectors.  The same basic injector is usually available in 1/2, 3/4 and full length.

Also, I have pointed you at injectorsonline.com for a good reason.  Read the info attached to each injector on offer there for Neos.....

checked them out on injectorsonline but that is AU, by the time I pay postage/ tax and ... it cost the same as what I could buy here hence why I wanted to fit r35 injectors as they are way cheaper

have you used xsprut ? at £392 doesn't seem to bad

Your tuner is a moron, find a new one.

I run 1550cc injectors and my car doesn't die at the lights nor does it flood the engine.

    • 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.   
    • 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.
    • 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!
    • 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.
