Currently looking to upgrade the turbo on the R33, as I already have the SAFC I was wondering if only tuning fuel and not timing would be a major issue with the new turbo? The far off goal is really only 250rwkw eventially with a PFC, but for know the budget will only allow the turbo, I already have a pump, FMIC etc... so I'm aiming for maybe 230rwkw for now, could it be done with the stock AFM and injectors or otherwise I could stretch the budget and get the Z32 AFM and I was thinking S15 injectors would be a cheaper option. So yeah opinions are welcomed but feedback from people who have been there and done that would be appreciated too, thanks.

Unfortunately as you are probably aware, the fuel/ignition relationship doesn't work very well, with a fuel bender and is defiantely the limiting factor in the power made. I wouldnt push the setup too hard, and consider the SAFC a bandaid which really needs to be fixed to get the most out of the supporting mods. Maybe have a look at the Greddy emanage Ultimate as another option, as its not as $$$$ as PFC's are getting

SAFC + SITC + Z32afm + Nismo FPR isnt too bad an option, as far as bandaid measures go

200rwkw from an auto is definately doable, so add a few rwkw more on for a manual

Ive got Deatschwerks 550cc injectors waiting to go in, but will be doing the remap option (in lieu of aftermarket ecu) when it comes time to put in the injectors, boost her up a little more, and tune (will keep the piggybacks for extra tuneability, I reckon).

I got 230rwkw out of my rb20 with an safc2, runs fine with good tuned afrs (its posted rb20 performace thread), I still get 500kms to a tank. Although im getting a remap and z32 though as the afm maxes out slightly on cold days. I think throwing some good timing in will sort out the small compresssor surge i get when slowly ramping up boost under load and the other advantages of more power quicker spool up etc..I have gtr injectors also.

so if i was to run a safc2+sitc would getting an r33 ecu remap aswell be advantageous?

they are a fair bit pricey though arent they? i would guess the costs of a remap would out weigh the benefits.

i ask because i am about to install safc2+sitc and run with standard turbo+injectors+afm and aim for around 200rwkw

then upgrade turbo and injectors for 250ish rwkw at this point ill probably need better management, perhaps an ecu remap.

i already have other supporting mods etc

    • Whoa, that's a name I've not see for a long time! Sorry to hear about the engine / turbo damage.  Fwiw with any engine problems it often really a case of just seeing what happens when it's apart, ymmv - I wouldn't rule out the possibility that the damage isn't even from the turbo failure, or possibly from a combination.  The airflow between cylinders isn't dead even, injectors can go off over time as well, with the turbos overboosting if you didn't have upgraded fuel system there could have possibly been a bit of leaning out - stock triggering is often a bit unreliable by this age too.  Basically its an old engine and a few things could have been going on, and you won't know how much work is needed until the engine is apart.  
    • I'm just shocked there's a euro driver on our roads who is thinking of other road users and not attempting to blind everyone. I wonder if Prank uses his indicator too...
    • Its hard to tell really. The Q50 owner's forum talks about it a lot and has quite a few people directly affected, but no idea what % of cars sold actually had the block replaced. Also, there seem to be 2 distinct issues which both get diagnosed by Infiniti as requiring a block replacement (no wonder they are going broke) 1. "Porous block" where coolant mixes with oil through thin or poorly cast parts of the block 2. Head coolant gallery plugs not sealing. If I was noticing engine coolant loss I'd start with cooling system pressure test (as always) and then I'd pull the cam covers and reseal the coolant gallery plugs on both side before worrying about a potentially porous block.  If neither of those did the trick it would be put in a second hand engine out of japan; I haven't checked pricing but I'm sure there are plenty around by now as they've been in production 10+ years
    • To clarify what I posted above, I thought you both had a situation where it cancelled sooner one way than the other.....if it is reasonably even where it cancels in either direction that is probably normal (consider gentle movements like lane changes, you don't want it to need half a turn of lock to turn the indicators off)
    • Son, in this country, that is a piece of Gyprock. f**king drywall. FFS! I also like the autocorrect of trailer to tablet. I was reading it and thing, "what the hell drugs is he on?" Then the photo made it clear enough.
