Do I Need A Z32 Afm?

I need to buy a new afm now as the one I have now is playing up.

I'm about to fit a gt2530 turbo, pfc, gtr injectors and 040 pump to my r32gtst, however not till after christmas.

I'm chasing 200 rwkw give or take.

It seems pointless to me to replace the afm with a stocky but some people seem to make this power without changing to a z32 afm.

If I buy a z32 afm now and fit the pfc and select the z32 option will the map run the car satisfactorily without an immediate tune?

Stock AFM is fine, but the Z32 AFM is a better unit for tunability and future proofing.

If your stock AFM wasn't playing up I'd say leave it for your 200rwkW target (or until it becomes a restriction), but I'm going to take a guess and say you're not going to want to live with "only" 200rwkW forever. At which point, your replacement stock AFM is going to be a waste.

And its not like the car is going to perform worse with the Z32 AFM at your current level of tune because it can't cope with the lower airflow, so there's no technical negative to it.

Be a man.

Do the right thing.

I've read a lot of threads on this.

My conclusion is that either afm would work for 200rwkw.

I'd probably buy a z32 afm later but have been forced to decide now due to the stocky failing.

The main point of my thread is to find out how well the pfc will function with the z32 afm on it's base map until I can fit my new turbo and 444cc injectors and have it fully tuned.

U may as well get a Z32 meter coz it really wont hurt especially with a pfc, however running a HKS GT2530 u dont really need a pfc, if u upgrade your fuel pump and get a HKS FCD and maybe a fuel regulator to adjust fuel pressure you should be good to around 220-230kw at the rear with your standard injectors, u can get ur ecu remapped and your rev limiter changed to 8200rpm and u should have one sweet ride

      Jacks that fit under GTR lips that can reach the subframe?

      You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!

      http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.

      R32 GTST - 600KW+ RB28/CD009 Build

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
