is an adjustable FPR and larger fuel rail necessary? stock fuel pump?

we dont recommend products unless completely necessary.

For around the same price as SARD 700cc injectors we got the rail, injectors and reg for. The injectors we now use are 750cc Siemens items and have 14mm tops and will not fit the STD rail...they wont even fit a Jap aftermarket rail. His Nismo FPR he already had fitted will not bolt to the Hypertune billet fuel rail so the Turbosmart reg was fitted.

So yes the FPR and fuel rail were both required.

He can now sell his almost new Nismo FPR and be well in front...any one interested in purchasing this can PM Bakes. He also has a set of R34 GTR turbo's and STD injectors in excellent condition that he is looking to offload. :)

He has a Nismo fuel pump already installed.

Bakes is the turbo hard piping something you had already or was it considered a neccessary mod? I'm considering something similar for mine. Is it locally made or Jap?

Cheers

HKS piping kit Scoob. Same as i used to run...see Trojan as they bought my old kit...they might sell it to you.

Thanks for the lead Paul. Are they neccessary? Scott would prefer me to get rid of my stockers on the 26/30 as he thinks they might be restirctive, but I've not heard evidence of that for engines below 350rwkw.

Bakes can you please post a pic of the whole turbo side of the engine with the piping installed.

Cheers

Car is tuned and running sweet, however on the dyno we couldnt get it to make over ~240AWKW at 1.2 bar (17PSi)

We worked out that the stock Nissan Cat between my HKS front pipe and rear section must have been restricting way too much air flow.

The cat got KO'd today. The car feels good and the new turbos pull to all the way to red line.

Ill try to take some pictures of the new catch can, etc tomorrow If I get 5 minutes of spare time to firsty clean/wash the car/engine bay.

Will have to head back to the dyno with Guilt Toy some time in the next couple of weeks and see what it pulls now. Might even crank the boost up to 19PSi or so.

so @ what RPM do they hit 1bar in 4th?

why not fit a metalcat?

Dunno mate, will have to check. Will definately have to go back to the dyno. Car should put out >300AWKW with my mods easily at 17-19PSi

Will have to see what effect the cat mod had. If that hasnt helped to free up a bucket load of power, I dont know what the problem could be.

I wouldve thought you could pull 240rwkw with standard turbos and supporting mods, dont know if youve mentioned what power your car was running before this series of mods.

Good luck with the re tune. I have a vested interest in this, was tossing up which turbos as well.

^^ Yeah, I did pull 240 with my standard turbos with stock injectors with just a boost controller.

Car should be making well over 300AWKW now. I cant tell on the street, maybe the problem is somewhere else?? If it is I dont know what??

Have to get back to the dyno and see if the cat has helped free up the power.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      I was using the wiring diagram I have So 12.74V is coming into the rear Fuel Pump relay as I measured.  When I turn the key to ON im getting 0.6V to the Fuel Pump plug; which i assume is backfeed voltage and doesnt include the 12V from ignition power.  The rear relay is working and being triggered.  From the diagram I clearly see the rear relay 80 = Rear Relay going into the Body/H loom (R-27) 27 = Fuel Pump plug going into the Body/H loom (T-20) 40 = Short Connector (R-27) I'm reading 12.74V on the blue/black wire which is the power for the Fuel Pump   From this diagram I can see the Ignition relay goes into the front and up to the ignition  2 = Fuel Pump Relay <1M> (R-27) 37 = ING Relay <1M> I started from the pump using this reference Which the way I read it (referencing Nissan wiring color codes) is: Pin Wire Color Function 1 B/P (Black/Pink) Ground 2 L/W (Blue/White)        ECU Trigger 3 SB (Sky Blue) Fuel Pump 5 L/B (Blue/Black) 12V Constant Tested SB to SB on Fuel Pump for continuity - confirmed Tested negative on Fuel Pump to 12V battery and L/B - confirmed 12V Pulled the relay putting 12V between Pin 1 & 2 and testing continuity on Pin 3 & 4 - confirmed relay   So that has me looking at this part of the circuit to understand whats happening here...and im still confused. From best I can tell; the disconnect is back to my previous diagram; between Ignition Relay and Fuel Pump Relay...which yet again; afaik is where the immobiliser should.    Thats what I was trying to explain to GTSboy; im not trying to fix it myself; yet I seem to have to get a Masters in Electrical Engineering (while im busy doing my actual job of DevOps & Cloud Engineering) somehow.  I just wanted more expert opinions; or more so that what I tested is correct and proves it to something around that area; to go back to the alarm tech (for a 3rd time) that he needs to fix it. He keeps telling me its not the alarm. He lives on the complete other side of the city so i understand not wanting to make a trip but as I said before if its the alarm it should be up to him to fix it. But he's adament its not; even though I pointed out the FP was immobilised through the original alarm. To my mind; it seems that the ECU is sending the signal; but the ignition is not getting 12V down the line.

      Maybe also really stiffly sprung track cars. Get the inside wheel up in a corner and all the fun stops. Also me sometimes (rarely) when I have to stand on the brake to convince the diff to drive the wheel that is still on the ground when I'm trying to diagonally get over severe driveway entrance, etc.

      R33 Fuel Pump & Brakes after alarm swap

      By Duncan · Posted

      I feel like I'm missing something. You had an authorised installer come out and install a new alarm. Post install the car doesn't start, and you aren't getting the installer back to fix what they did wrong?

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'
