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.

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
