Hi All.

I have a weird problem with an RB20DET in a 1990 R32 Skyline. When the car is left idoling for more than about 2-3 minutes wen i take off again once it reaches about 3 PSI the engine cuts out and the car jerks around. If i just coast along, turn the engine off then re start the car it goes ok. There is another problem first thing in the morning when the car is cold and i drive out my street even with only a tiny fraction of the accelerator pushed down the turbo goes nuts (loud and about 8 psi boost) and the car accelerrates normally if i ease off the throttle (to almost nothing) i can keep the boost down tho. if i drive the car without leeting it go in to boost it takes about 10 inutes but it kind of goes into another mode then works really well is smooth and quick. i have a hunch it is an o2 sensor issue or airflow meter??? what do you guys and gals think?

i'm getting the same problems too.. but i've got an RB25DET S1... changed the plugs pregapped at 0.8 and fuel pump... i'm getting really tired of it!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      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.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      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.

      Looking for someone with a R34 front bar

      By DraftySquash · Posted

      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. 😂

      new 1.5 LSD issues/concerns

      By Dose Pipe Sutututu · Posted

      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.
