    ok theres a few different oppinions out there but let me know if u think this will be a decent setup ...... i have a rebuilt big port 4AGE just bak to standard but im running HKS head gear and will have HKS cams just deciding what ones to run (any ideas?) i will run a SAFC (only cos i have one here) just for now bu twill be running a after market ecu later ... and i wanna run quads do you think it would work well or not i already have decent extractors and stuff there so the way im thinking it should be ok what do u guys rekon?

    also anyone got any ruff ideas what kinda power it would make with this setup i know the cams will play a big part in it but a ruff guidline is all im after

    if you have bigger cams, and a bit of port work etc.. and want to run quads also..

    an SAFC will not be enough..

    the SAFC will only help on WOT.. not on idle/cruise/town driving where most of driving is done..

    just save up a little more and go full aftermarket.. then you can get the full potential out of the motor..

    i was struggling to keep up with a stock reco'd bigport when i had the stock ecu on my motor i built.. (JAE86) but after the ecu.. pulled car lengths on some 20v powered ones!!

    Matty, are you sure your info is correct?

    SAFC's can make two sets of fuel changes .. high load, and low load. You can set what throttle changes differ this (i.e. high load = 60% and above, low load = 20% and below), then the computer makes a curve between both loads.

    I know that i have used a SAFC to road tune my girlfriends silvia, which has an RB20, HKS 2510, and unknown injectors.. While i didnt touch high load much (didnt want to risk leaning-out without a EGT and air/fuel probe), we mucked around with the low load settings enough that it became very driveable. To give you an example, you were almost choking at idle from how rich it was running, and even at highway cruising you could smell (and see) the rich smoke.

    I don't mean to sound rude, i just don't think you have a proper understanding of an SAFC . Plenty of kiwi kids have used quads, SAFC, and 270+ cams to very good results.

    Yes, they can't adjust timing and whatnot, but they are great for the money (if you buy them second hand, 200-250$$)

    You could have cams too But yes, definitely works.

    I'll be doing a writeup on a budget quad setup sometime in the next couple of months.
