Finally, after years of trying I took my first round win in Sports GTB. Thanks to Steeline, David Clifford Photography, Cable Mate, Dejay Signs and Benson Motorsports.

Car now is a rocket with 300kws. I wish I had it this good from the start. We have had to overcome a shitload of dramas the past year or so and hopefully now we have the speed, we can have some luck too!! Thats why Im wont be driving the car to its full potential. Best time was a 59.3....without trying too hard!!

Roll on R4 Aug 21st at Symmons!!

do you mind adding some specs of what you have now. engine? box? turbo? suspension? only if you dont mind.

Yeah I'd be interested too if you don't mind sharing, also what tyres you're using.

Tanks guys!!

60sec at Baskerville, 61 at Symmons cut off times for B

well after my original block was ruined, we have replaced it with a 25 block, still have the 20 head. replaced the high flowed Rb20 turbo with a garrtet gt 30 (rb20 turbo i want to sell now) the gearbox is standard, i need another diff ratio as im having to change gears at Baskerville too often now. suspension is a BC racing kit. Tyres are bridgestone RE55.

After the amount of money ive spent and dramas etc I want to make the car last (hopefully) so that is why I wont be driving it full bore (even though it feels wrong!!) I want to be racing not fixing the damn thing all the time, which is what we have spent the last year or so doing. I did think about detuning it, but then I would have to drive it harder, so lap time mangement is the way to go. But at some stage I will do some testing just to see how fast I can go!! Im just not made of money, sponsors help, but Im still paying for 90% of it!!

R20 head on 25??? did you machine the head out so the bore matched? open the ports up? How come you didn't run a 25 head, could have got vvt goodnes?

just cost. didnt want to have to change the wiring and the ecu. Im not sure if the head was bored, but we have different pistons in it. head not ported either. forgot to mention that i have a after market exhaust manifold and a GTR style intake. ill post a pic later.

Yes pics please. I'm surprised you can run the 20 head on a 25 block.

from what I know, the heads are not much different, but you have to run different pistons. there's alot of myths about these engines! I dont run resister packs either!

Congrats on the win John, hopefully its the first of many.

Was it a 25DET head (series one I assume) that you used? Also when you say you dont run resistor packs, I take it your running GTR injectors, what ECU?

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      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

      S1 rb25/s14 starting problem

      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.
