Hello from the other side of the world, and north hehe....Im in ottawa, ontario, canada and i just finished up my s13 rb20 swap...unfortunately it wont start...

I turn to you guys because there isnt a huge group of RB users up here...Now, the starter cranks, theres fuel that i can hear, and there was pressure in the lines, the injectors are all grounding through the ecu fine, afm, o2 sensors are hooked up, new plugs, i have power going to the coils, but it wont spark when we put a plug in and grounded it, no arcing....no nothing!!!!

Now, after lookin at some diagrams on the net, i see that the problem might be with the ignitor chip...Maybe one of you guys could help me to diagnose this problem eh, cause this is rather annoying, cause im losing out on alot of work, and i gotta pay this swap off...

Any help would be greatly appreciated

Thanks

Ciao

You have no spark... What about injector pulse?

Its either the Crank Angle Sensor (CAS) or the black igniter pack at the back of the rocker cover.

They are the two things related to that, and ive had similar problems many years ago

I was looking through the diagnosis thing in the R32 manual and I saw that if the CAS wasnt right, it wouldnt ignite....how can i check to see if that is working right....

The ignitor chip shoudl be tested...but how do i do this? i saw in the book it said to test resistance betgween the coil side of the harness to the coil, and hsould be 0, as well as between pins 1,2,3,11,12,13 on the ecu connector to the c/u side of the ignitor, should also be 0.

      Well it wasn't as easy as I thought.... and it also wasn't in my original manual which I did end up finding. They discuss the process in the Nismo catalogue though and it requires slight machining. Page 145.  NISMO PARTS CATALOGUE 2020

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I'm an idiot, my intercooler is rated for 1000hp. I had clicked on the wrong product. Knowing the delta P would be nice, but I'm doubtful I'll do it. Now as for an EMAP, that would be great and I'll get around to it eventually but from my findings in my last post, I'm considering a turbo swap now.

      You sir, big win tonight. Precision never supplied compressor maps in the past and Idk when they started, but it seems they only offer for a few of the older gen2's which is exactly what I have. I punched in some numbers and seem to have gone with the wrong turbo. 600-700whp isn't in the most efficient area and is close to the choke line. 800whp is well off the map. Punching the numbers into a 68mm gen2 turbo map is bang on in the center. Here I was thinking going smaller would shift the power band down, but in reality it would just make it so much worst due to my rev limit. I would have never thought.

      Increasing overlap will bring the torque down earlier (and make your idle sound sick lol). Worth a shot (if you dyno time) to experience a bit (providing you are confident your valves won't kiss your pistons). Is to just take off 5 degrees across the boosted area of the map, and then retard the exhaust cam let's say, 3 degrees at a time and then overlay all the runs with VCT on all the way and VCT off as soon as you make positive pressure. Ideally you would have a total of 6x overlays to looks at 0 exhaust & VCT off once manifold pressure is +ve 0 exhaust & VCT on all the way -5 exhaust & VCT off once manifold pressure is +ve -5 exhaust & VCT on all the way -10 exhaust & VCT off once manifold pressure is +ve -10 exhaust & VCT on all the way Just leave your O2 wideband closed loop on for all of the boost area & RPM, and hopefully there isn't too much fuel correction needed and the Haltech is fast enough to compensate (I do this, then apply the correction to the main table). Getting that overlay data should give you a good indication of what to aim for.

      So, my main limitation here is that the car does not have an oil pressure sensor by default, just a switch. As part of my tune I bought an oil pressure sensor upgrade so I now have access to oil pressure levels and logging rather than just the boolean behaviour of the switch but this means I need to use the tuning app to display this value. So, this rules out using any other app on the iPad. The app will also flash when pressure drops which is a nice feature. I have replaced the centre screen with an Android one, which is awesome for Android Auto, but I think it might be too far away and out of my line of sight. I might add some gauges to it this weekend and just see. I guess if its just temp and oil pressure I can make them massive! 🤣
