Ok guys I have a couple of questions that I was hoping someone may be able to help me out with. Firstly I currently have a PFC, EBC, and Z32 AFM waiting to be fitted to my R33. Only other mods are 3in turbo back exhaust and a FMIC. I have plans to upgrade to GT-RS turbo early next year (also injectors etc.). My question is would it be worthwile fitting the Z32 AFM at the same time as I get The PFC and EBC fitted/tuned (now), or would I be better of waiting and getting it done at the same time as the turbo upgrade (next year)? Basically what I really want to know is will the Z32 AFM give me any sort of additional power gain when installed with my current mods?

I was also wondering is it alright just to use the PFC hand controller as a boost gauge? As I currrently only have the stocke boost gauge. Or is there an advantage in installing a conventional boost guage? Like as a back up or whatever.

Sorry guys im a bit of a novice when it comes to this stuff, thanks in advance!

z32 afm wont give any power increase....but it gives the ecu more scope for airflow with using bigger turbos and more boost and more fuel. It will only be useful when you go for the larger turbo, but regardless with the powerfc it wont hurt to put it on now...its one less thing to do later on.

Boost gauge doesnt matter...i know heaps of people who just use the commander to monitor all the engine stats including boost. There is no special thing to do, just do whatever your comfortable with and suits your taste.

PFC would only show boost if you get the otpional Map sensor for it ..

Z32 i would install now as you cant just plug them in and select Z32 and the tune be same as before... you will need to shift the load map to match the Z32 .. which is usually back to the tuners.. so save any mucking around and going back to the tuner and get it installed originally..

Personally i would say it doesnt matter when you do it.

Now or later wont really matter.

You are gonna have to get a full re-tune with Turbo/Injectors anyway.

I would do the Z32 then, rather than now as you stand nothing to gain by going it now.

Just personal preference, and its been a while since i disagreed with Chris :)

nah that makes sense t oo Ash :) hehe i just am going through the hassles of having to swap mine over for new inlet piping etc with the change to a Q45 AFM and now need a retune...

so i learnt that i should have got it all out of the way in the first tune :)

so realistically, i would wait til i had the turbo and injectors and save that $300 tune .. thats 1/3 of your injectors that you wont get back :)

      Interesting, I've heard complete opposite on my end. Bit of a lottery I guess.

      Getting Dangerously close to being ready to go back in the car. Rockers in with clearance castings now (and a quick check with the USA for the torque settings for the larger custom bolts) Covers and ported FAST Manifold sitting on there. Not fully tightened down as there's some clearancing required for the water pump with the earlier LS1 water pump styles. Example of the clearancing needing to be done: The body has to be ground a little but I'm struggling finding an actual piece of it. The later variant of water pump resolves the issue as the manifold was designed around it. It only came on the VZ LS1 in Australia, it got a different pulley for Gen4 motors. (it also costs $450... vs... $0).

      Doing some height adjustment on front suspension on a v35 and noticed this. The passenger side looks correct. So wondering what's happened to the drivers side?

      Oh...I have the electric mirrors as well iirc ...they're in the same state as just about every other R31 door mirrors, with the 3 plastic screw towers broken/cracked in the plastic molding. All the interior is 'dry', so the mirror switches etc likely all work fine. Some pics below of the trimmer pieces ~ looks to me like previous owner, painted chrome finished trims with black paint ...ergo, the chrome underneath is likely a-ok... ...starts to look yukky posting stuff like this, how much did it cost in fuel on your last sortie up this way?...me just thinking aloud, borrow someone else's 4cyl to cut costs, come do your own pick'n'pull like before to save me some bother...hehe.. but whatever, I'll just earmark bits I know you want, because the way this is all panning out, I'll be able to retire the R31 from daily duty at long last, replacing it with a Subaru wagon I'm lining up in the wings...ergo, my attitude towards the donor pinny shell is starting to wane a bit, and I'm more than happy to help you out there... Like you say though, no rush...and I'll guarantee we won't be moving too far from this locale at any rate 😎
