refurbished injectors, are they usable?

Hi all.

I am budget building my r33 gtst now. Got hypergear turbo and pfc. Now looking after injectors. Planning to make 250-270rwkw.

Found these injectors on ebay. http://www.ebay.com.au/itm/6-Genuine-740cc-fuel-injectors-RR544-for-Nismo-Nissan-Skyline-R33-RB25DET-ECR33-/112089938321?hash=item1a1914b991:g:YkIAAOSwawpXq-aw&autorefresh=true

They are marked "- PROFESSIONALLY re-manufactured" and "- Spray, Flow and leak tested". I reckon they look good.

So just want to ask are they really good? Or can you recommend anything else that can do the job and is cheap?

 

Btw, what afm do people use on rb25 today? Still z32 afm?

Good and cheap don't really go together but in theory professionally remanufactured and tested injectors should be fine. The question is can you trust the supplier ? Are they enough of a saving to be preferred over brand new (and new technology) injectors?

If you are using Nistune then Z32 AFMs are still a good upgrade (if they are brand new and genuine) but if you are upgrading the ECU then you will be going MAP sensor

Cheap copy Denso injectors gave me bad hot starts and really bad fuel economy.

Poor atomisation, had to retard timing heaps.

They weren't made in Japan.

Had to rip em out and dyno tune all over again.

Tried to save $300, but cost me another $1000 to fix

That makes sense. So do you have some suggestion?

Thank you in advance.

      Manual Shifter slightly bounces/moves/vibrates when accelerating/deaccelerating

      Congratulations on your find  Did you mean it has 6k miles or was that a typo? Firstly, keep in mind some movement of the shifter is normal...it is a long rod hanging out of a box bolted to the engine. Having said that there are 2 next places to look: 1. Transmission and engine mounts. If these are worn or broken the shifter will move around more. They are reasonably easy to source and replace on a hoist, and possible but uncomfortable to replace car stands 2. On the bottom of the shifter there is a nylon cup that sits over shifter's ball end. If this is worn or broken the shifter will move around more than it should (but will still shift OK). That is a cheap part and requires removal of centre console, rubber shifter hole covers and a circlip in the gearbox shifter hole to remove the shifter. Re maintenance, as with any new import you should change all the fluids including transmission when you get it; never trust the seller and previous owners to have done the right thing. I am pretty sure R34 GTT is the same as earlier big box transmissions, so use any good quality GL4 75w90 trans fluid if it is shifting well (if it is hard to shift due to synchro wear, redline shockproof lightweight will keep it alive a bit longer before rebuild is required)

      Misfire/stalling issues

      By Chris_Guthrie · Posted

      Well considering I have the exact same problem with that as the original one I don't think that the ignitor is the problem. I would imagine that this being such an uncommon problem the possibility of getting a new ignitor that is bad in the same way as the old one has to be very slim. I'll definitely pull everything apart this weekend and check the turbo out. Got quite a bit of things to check out Saturday like fuel pressure and the pcv so I'll report back once I do that.  Thanks everyone for all the replies this is all really helpful

      Rb's have issues with bottom end starvation, not head starvation. Which either way, you probably wouldn't ever see on a dyno. Strange... What's pump gas for you? Octane rating?
