My Rb25det Stagea Engine Is Having Problems Starting


Recommended Posts

Hey guys got a staggy series 2 engine in the 32 gts4 at the moment. Was running pretty well with gt2871 turbo s15 injectors q45 afm and remapped ecu... took these all out and put it back to standard and now its having massive problems starting.

Car currently has:

Front feed plenum with larger throttle body

Rb25 neo afm

Series 1 afm (engine is series 2 but people have told me it doesnt matter)

Series 2 coil packs

stock rb25 injectors

Stock turbo

These are the onyl things that have been replaced

Its struggling to start.. have got it started a couple of times but runs like dog shit.

Plugged a power fc in .. still ran like shit and struggled to start.. obviously tuned differently but ..

Have injector pulse.. have spark..

Plugs foul up very quickly.. cleaned them numerous times..

Pull the cas out and spin it and injectors click.. not completely fluently but still click...

So given that.. im really not sure where to go from here

Any ideas would be much appreciated

if the stock ecu has been remapped to suit s15 injectors and q45

and you put the stock parts back in, it will run like a bucket of crap

likewise with the powerfc - i would expect same results

overfuelling, mega rich and just a boggy tune

my advice would be to put the PFC in and DATA INIT to factory defaults

then it should start first stop providing you have factory afm and injectors

or get yourself a standard s2 r33 ecu for 150 or so

Yeah heaps of fuel in the tank

Been told series 1 ecu should work but im having my doubts

an rb20det ecu was remapped.. but that has been removed and replaced by a stock series 1 ecu no remap
