I have a Nismo Pump, Nismo Fuel Reg,Highflow and a Z32 on the way.

Wanting 250rwkw...Should I do the injectors or max out the stock ones as I have been told it will work no problem?

My Gut tells me to get em but my wallet and wife says "Use the ones you've got"

Help!!!!! Is it too much of a risk???

def go injectors.

I upgraded to nismo 555cc injectors with my hi-flow set up. the standards were 90% duty cycle when giving it at the track.

got the 555cc's and max I have seen would be 60% with 235rwkw

Hmm thats what i thought but my tuner doesn't want me using them. Just nismo's 555 have certain issues, 740s are fine apparently. He said anything other then nismo 555's. Sards are too much stuffing around and not sure if tomei 555s are the same as nismo. I did have a reason, but forget at the moment. Will ask him again what the prob with them is....

555s have issues???? :teehee: Only the biggest and best tuning companies in the world use them not only on customers cars but their own cars.

Ive had them in my car for a year now,no complaints.

Yes i know this, that's why i'm asking the questions. Wish i could remember what he said to me lol, he explained a little problem they tended to have. Might be awkward rocking up with nismo 555s after he said not to haha. Dunno what to do?? Should i just buy em and say yeah i'm gonna run with 555s? Or go nismo 740s (i will have close to 300rwkw in the end)? :teehee:

Yer i know that but like i said, my tuner doesn't want me to run the 555s. Said i can run the 740s as they are different. Price is of no concern. Will have to call him up tommorrow and get the low down on the situation.....PM me if ya like to talk further :teehee:

  • 3 weeks later...

Getting excited now, have just sent turbo to be hiflowed... been told its getting a TO4 compressor and 56mm exhaust wheel, dunno what that means really but it sounded good....Bigger than whats in there I bet so thats a bonus.

Next are injectors then off to the dyno I go.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
