hey all i have worked out that my r33 was cutting out randomly because of the earth wire that comes off my ignition or coil pack loom has heat damage and gone hard and stuffed, tried fixing it striped it back and reconnected it a few times but the wire is shaged .

can anybody give me suggestions on aftermarket or alternative setup eg totally different ignition coils and leads to plugs im not sure wats been done and what works best. im running 387hp so if there is a bit of an upgrade that would be great but im strugleing to justify 300+ dollars for nissan genuine loom thanks guys.

Nissan is best - its a 10-15yr old car so IMO its a worth $300

stock igniton/wiring systems are good for over 500rwhp/370rwkw (ive done it) so going with stock even if a little more expensive will ensure you have a faultless setup

Could go with an AU coilpack conversion mate?

S1 AU Coilpack, plug from the AU coilpack, 6 HT leads to suit, with spark plug fittings on end.

Ensures the coilpack is kept away from heat and leads are more reliable.

Bit of a write up here -

why change the factory setup? its proven and reliable. it's lasted decades. did you 100% figure out it was the earth wire or was it your coils?

heaps of high HP cars running splitfires with factory looms.

yea with the car running i wiggled the earth and it cut out tried many times and same thing every time i wiggled it so no doubt it was earth wire.

yea i think ur right about standard i was just curious before i spent the 300 to see if there was anything better for the buck but doesnt seem like there is much ill keep the splitfires and standard loom i think.

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
