KA24DE RUNNING RICH

[GH.00.HA]

high all, ive done a conversion on my u12, its now powered by a ka24de as opposed the e, im unable to get the car running correct (the motor has been stripped and rebuilt to suit a turbo) so its had a little bit of work, anyway its all back together these days but i cannot get it to run right! its running rich blowing heaps of black smoke and fouls plugs very quickly, i had to replace the dizzy with a non genuine dizzy which i seem to think may be the problem, there is no injector dribble, the fuel pressure regulator is working, timing is correct newly replaced AFM, O2 sensor, coil pack...i have tried just about everything and ive run out of options, ill run the ecu to check for errors sometime tomorrow but has anyone had this problem? the motor was running 100 % before pulling it out of the u13 it was in (besides blowing blue smoke due to leaky valve stem seals) so unless ive done something wrong in the wiring department then there should be any dramas

does anyone have any ideas or could possibly help, im in need of help desperately

if you say the motor was built for a turbo in-mind..then the injectors may be to big for a NA aplication..check the injector CC rating and compare it to a stock NA rating for the same size engine...you may have to downgrade.

im currently running the standard injectors until it is time to turbo it

[liquid_cool]

do you have a standard ecu allso?..or a flashed ecu for turbo maps?..are you running a standard fuel regulator?

[GH.00.HA]

mate everything is standard untill i sort this issue, standard ecu (auto ecu, cars manual) standard fuel pressure reg standard afm, throttle body etc etc theres only been internal work on the engine (ported/matched valves, decked head)

have you checked the vacuum to the FPR? or the fuel pressure? how do you know the fpr is working?hows your spark? do you have a way (DSO) to check the O2? youre SURE the timings right.Go through the fsm, and go thru the idle/mixture adjustment procedure

everything is as it should be, the engine was running fine previously to the rebuild

im going to try using a aftermarket fuel pressure regulator
