Hi,

I've still got some on going issues with my car. Basically what it does; it will run fine. Then you'll hear it drop down in rpm, almost like it's going to cut out but it doesn't. It will then pick up the rpm and sit on about 1100 or so; when running normal it will idle at 900.

If you rev it up, you'll get to 2,500 rpm; but it won't go any further than this. Will just bounce up and down 100 rpm or so and does not sound good, It's difficult to explain. Anyway I think it's the AFM's. I just replaced the Fuel Pump..this has no effect.

It seems definately like a fuel related or air flow problem.

I wanted to see if anyone has some working AFM's for an R33 GTR that I could borrow, before I go ahead and buy some after market ones.

If I do use aftermarket AFM's I would assume it needs to be tuned? Is this correct?

I've tried looking for standard AFM's; but can't find anywhere to buy them. Heard they are rediculously priced from Nissan.

Or if anyone has any ideas on this problem, feel free to post :)

Thanks,

mate try SSS Automotive or Just Jap in Sydney as they will most likely have some. they also appear in the for sale thread. original will be stupid $. by aftermarket do you mean Z32? if so you are right it'll need a retune but also changes to airbox etc if you're running one or at least pod adapters as Z32 is a different diameter.

they can be repaired in some cases, at times they suffer from dry joints. crack the top off the AFM by carefully cutting around the square cap which is secured with sealant and have a really close look at the pins that attach to the plug. it's obvious when you take the top off. sometimes you can't see the break so resolder them anyway. search the forced induction thread it's all there. it's worth a try some people have had good success but take it to an electronic repair place if you're not confident. there's also a place called PLMS in Adelaide - do a google search - that has repaired them previously.

After all, it was the AFM's. Who would have thought the first set I swapped would have been dodgy lol.

After getting some more AFM's from Sly, the problem is fixed.

Thanks, Sly. Appreciate the help.

I've driven the car to the coast yesterday and it's running absolutely perfect!

It seems like it's never run so good!

      I always wonder where the obsession with legal/illegal spacing on number plates in the UK comes from. Because it comes up in comments in every UK-based video I see on youtube. From my point of view all of your plates look a bit odd. Just because there are no markings whatsoever. In Australia we have the state that has to be on it. In Europe you get stamps and state logos. Yours look a bit like a throwaway draft that people then stuck with. And attached with blu tack so that it falls off at the slightest disturbance. Not trying to hate, but it's interesting how things are done in different countries. Do you have to follow a lettering convention when choosing a custom plate?

      "Cheap" bolt on turbo on RB25DET NEO

      Hybrid sounds like a supercharger... It's half a turbo, with a belt to drive it! Oh wait, they're just called super chargers...

      It's either an ignition failure or a fuel failure.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      Before starting any work, we attempted to adjust the tune. However even after adjusting it to certain extremes like completely stopping fuel, it had no effect. What fixed it was removing the Nistune Board and installing the original EPROM instead. This immediately fixed the issue. Everything should have been fine with the Nistune Board installation, so I am unsure why it has caused a problem. The soldered connector is also properly soldered. This worked when I first got the 550cc injectors, before cleaning, but that may have been a coincidence.  We ended up not installing the fuel pump hanger (at least for now). So currently running stock injectors, stock fuel pump, stock fuel pump hanger – Well everything stock except the exhaust. Now I have around €1400 in Nistune, Injectors, and Hanger collecting dust for the time being, perhaps I'll install them in the future. For now I'll enjoy the car as is 😁 Thanks a lot for all your assistance, I really appreciate all the help you have given me.

      Why am I hitting a power wall with my stroked RB25?

      The turbo can’t be the issue. They’re proven to make much much power than you’re making. There is something in the setup that isn’t correct. - has the exhaust got any silly step downs? - what exhaust manifold?
