I am after the magical 500rwhp and I have been told by a few people that the Nismo 740cc injectors wont cut the mustard and that will need to upgrade to a 1000cc injector.

I cant really believe that this is true.. does anyone know what power nismo 740cc injectors would be good for ? its on my RB30DET.

I dont really want to run more then 92% injector duty

or is it 15 to 17cc = 1 hp ... i forget.

EDIT: I think that's at engine... and a typical calculation for normal modern cars...

Im sure that Nismo 555cc injectors are rated 555hp, and 740cc injectors are 740hp...

Nismoid, do you have 360 rwkw in your r31? far out, she must chirp seconds. how's the response? like when do you get full boost by? rb30, 25 or 26?

Anyways, so answer your question, sydneykid usually says the cc rating is approximately equivalent to the hp.

    • That still isn't a lot to go on. I don't have a Y50 Fuga Head Unit wiring diagram. I can say that a lot of nissans of that age shared head unit plugs, so if you are in Australia something like this would probably help: https://aerpro.com/app091# You plug that into the car loom, then either plug the head unit ISO into that (if it has ISO), or you buy and ISO adapter harness that you wire in. Bit of stuffing around, but once you have ISO its easy to change things in future.
    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
