Turbo Uprage With Safcii

[R33silverS2]

Hey I know a lot of people on here are fans of the power fc, but I wanted to know if it was possible to put on a high flow or aftermarket turbo and run it with the safcII? Obviously you can bolt on whatever fits pretty much, but what i mean is can you make good power out of for example a highflow with an safc? eg 220-230rwkw? Will the stock injectors cope at this level also?

Thanks in advance

Yep, you can run a highflow with only a SAFC, and get about 210rwkw, any more then that, and youll need a z32 AFM, injectors and better engine management. PS youll need to upgrade your fuel pump if its the dtock 10year old one, and do the fuel pump wiring mod

You will also benefit from getting a SITC, soy you can trim the ignition tables.

a bit of topic but wat is the fuel pump wiring mod?

Ive got a bosch 040, yeh what you mean by wiring mod?

Its in the FI sticky, gives the pump a constant earth instead of runnung through a resistor pack, so it gets full voltage

Thanks Adriano.

Anyone running an aftermarket turbo with an safc? I saw a thread about it but no results were posted mostly just talk about the idea. And if so what power are people pulling?

Some people claim to make 230rwkw with a safc, even with an SITC, i would say that is the absolute limit, have you considered upgrading to a greddy emanage ultimate?

Yeh i have thought about that as well, does it pretty much do the same job as a pfc whilst being a piggyback? It's just gotten to that costly stage where more power from here on starts to cost big bucks...

its very possible i got 244kw at the wheels from a rb20 with safcII and bigger turbo. safc only modifies the airflow meter signal going into the ecu. so u can only tune it within the scope of the standard fuel maps. it does not change the ignition timing directly, as u can do with a power fc

Rb 20's seem to work slightly better with safc's due to them no having as much R&R built into the standard map. Unfortunately a SAFC does change the ignition timing directly, as it makes the ecu access different load points, and it usually effects it in the wrong direction, usually you hit detonation problems before you can lean out the mixtures enough.244kw, was that using the standard AFM?

yeah thats true rb20 computers seem to be a lot dumber than rb25 ones. yeah that was with the standard afm.

Wow thats a really good result, If i could do that on my rb25 i would be there for sure! What boost were you running for that?

Yeh i really REALLY dislike the whole r&r thing, anyone knnow if it goes away completely with a e manage ultimate? Perhaps the e manage could be a good option as pfc are become increasinglty hard to find.

[Adriano]

Maybe try taliking to URAS, he knows a bit about the emanage(lol)Have you read the thread
