Hi guys, this is my first post in this forum and i hope that u guys can help me.

Im BOB..and i would like to ask some question to u guys.

Rb20 are using top feed,high impendence, 270cc injectors

4G93 are using top feed, low impendence, 450cc injectors.

RB26 are using top feed, low impendence, 440cc injectors.

am i right??

Did some research, most of the RB20 owners fit in the RB26 injectors with resistor pack.

But, I found some article in other forums mentioning about fitting in a 4G93 turbo injector in an RB20.

My question is, can i use the GTR resistor pack with the 4G93 injectors??Or i have to use the 4G93 resistor pack??

I hope everyone in this forum could help me...........

Thank you in advance........

Standard rb26 yellow top 444cc injectors are 2.0 omega resistance. Yellow top 4g63 injectors are 2.9 omega resistance.

So I probably wouldn't use a standard GTR resistor pack, although you would probably find it would work OK. Best thing to do is go down to dick smith and purchase the correct individual resistors and wire them inline just above the plugs on the live 12v side. If you take those figures down to dick smith they can even look up the resistor colour coding for you and let you know which ones to purchase.

That will cost you about max $4 plus its more accurate. A resistor pack will cost you atleast $150 from a GTR.

    • 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. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
    • It's TWO steering wheels actually. 😛 one for each hand They are wheels, and they steer!
