I'm planning to upgrade my injectors soonish so I've started to look around now. My current injectors are a little sus, as my fuel tank was rusted to the shithouse and some of that red stuff must have gotten through the fuel filter. Starting is difficult and fuel economy around 14L / 100km.

Getting a nistune in a couple of weeks, and apart from a 3" hiflow exhaust my HCR32 is completly stock, so I was thinking a more modern type of injector with improved atomisation would be better for response and economy, does anyone have opinions on how these ASNU / Bosch injectors compare to the Nismo ones?

Yep, not sure why but GTR injectors just seem to give poor economy from the tuner I spoke to, he said they also commonly leak through the injector body, I know mine did both of these things but I can't comment on the truth of how common it is or why.

Sorry for thread jacking but any opinions on the ASNU1000cc injectors heard they can improve economy.

Old thread I know but I have a quick question, Instead of wiring in 6 resistors close to the injector can you not just wire in 1 resistor on the 12v feed before it splits in to 3 then the other 3? Just 2 conections to make instead of 12 or is there something im missing?

As it is batch fire 3 injectors fire at once, so if you multiply the resistance by 3 and use a single resistor it would work imo.

Sorry my bad divide it by 3 as V = I*R so V/I = R so if you have 3x as much current you require 3x less resistance

12/1.2 amps = 10 ohms, as 3 injectors will fire at once you have 3x as much current so 12/3.6 = 3.33 ohms

Obviously the battery is closer to 13v and hence lower amps but the theory is the same however you probably can't buy a 3.33 ohm resistor, to get an equivalent resistance of 3.33 ohms you could run 3x10 ohm resistors in parallel bunched together, be easier to solder in one big lump than putting one on each injector.

Up to you I guess.

What is the nicest way to wire the resistor to the 3 injectors in the sub harness so you can still unplug it from the main harness when pulling the motor out?

I understand that for one injector you could use the existing wiring, but what about the other 2 in the sub harness.

Hope that makes sense

no nistune/ ecu talk... cant even get the ecu in diagnostics mode :dry:

engine does crank, did not start when pump was hard wired, injectors are getting power

am going to install stock injectors again and redo wiring back, isnt the daily so not a big waste

    • Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.
    • Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.
    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
