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

    • Maybe I also should have wrote that a bit better lol. I did come 8th last in English at school during the HSC, ironically spent 2 decades reading/writing specifications and contracts in IT 😂
    • Right, but that's in-cylinder, there's the interaction between that and the TWC which complicates things. Pulling out timing to reduce NOx is a strategy I saw in transitional emissions vehicles like stuff from 1974 or so. The two inlet runner system is interesting but I'm not sure it makes a huge difference as far as emissions goes, is it a tumble valve? I've seen stuff like that even in cars from the late 80s. 
    • Hello all,   so i recently swapped out my rb20de neo with an rb25de neo( engine,transmission, wiring and the diff everything) but i just cant get the gear indication light on the dash to work when i switch to tiptronic mode. Note there is a steering wheel switch beside the shifter and i dont have that. I did notice yesterday while switching to tiptronic that the indicator on the dash started to work but it didn't afterwards. Does anyone know how this actually works? Or do i still need that steering wheel switch to be connected and on for that gear indicator to work?
    • Hence why I said earlier that I don't think the turbo Neos ever would have actually qualified as an LEV. I suspect the only actual LEVs that came out of Nissan were the NA Neos. Still call them all Neos. They all stil have the Neo-ness. Just that they don't all qualify as as LEVs.
    • It will give gains, but you wont hit 600 It will give gains but it wont get you to 600 imo. You will also sacrifice low down and you will be adding extra volume if you port match it, more so if you port the plenum runners depending and how its done I think the only time youre going to see about 100hp gains is if the car is making well over 1k kw I do have a spare set that I was going to test with, but i dont actually think there is anything worth getting going larger. I did a fair few S14/S15 and the standard TB is fairly small, I went to 60 and in some cases 64mm which is significant over the stock unit. You can also get some weird ratio changes. I think 20kw will be a stretch on a roller dyno. If I had it apart I might mill the shafts a little and not expect much, I think the stock size is still pretty good for a street/track car even with larger capacity. I might change diameter it if its a drag only car
