Just posting this up for Ben. Apparently was tuned today at CRD, on pulp and ~20psi made 394awkw. Full boost is late 5000ish rpm. Street exhaust, no playing with cam gears yet, more to come later. Will be at the Sports Compact event next month at WSID.

The car is still a 2.6L with tomei 260deg cams

and forged stuff inside.

The car made the power running a trust street exhaust wich is 3" piping with a 70mm muffler.

also the was running 22psi on optimax.

Last time when we put on our 4" race exhaust we made another 30KW at the wheels, so we'll see how it goes later with that on.

Jim did a great job tuning the car.

The car will be at the track for compact attack but currently the car will not be running as we can't afford a new gearbox just yet.

Thanks to the guys down at Hypertune for doing all the work on the car and installing the new plenum and throttle body.

The T88 is a 33D wich is the smallest T88 they have made and is no longer available.

why not the T88GK, because the GK is rated at 1100hp where as the 33D is rated at 850hp.

The car is very nice to drive arounf the streets.

it makes about 120AWKW before it comes on hard. a stock GTR makes 160AWKW.

The turbo looks like it should make 500 with some other little things added.

as for the bleeder system was done by Hypertune.

No there isn't a V-band flange on the turbine housing.

The car is now an absolute freak to drive now!

Freak as in all or nothing?

Nice to drive around the streets as in off boost or do you always drive around the streets above 6000rpm?

The plenum looks like it makes it more laggy as the lack of midrange is bordering on a joke? BRING BACK THE JUN PLENUM

All up very nice for drags shame you wont run it as plenty of GTR's run 10's with stock gearbox

They don't for long though......Nissan 3rd gear + high rpm quick shift = BANG

There are not too many 10 sec cars running stock boxes....Not in Australia anyway. Theo broke 13 boxes to get his 10.78.

Lets not be too critical fo the setup...it is running a 3" exhaust, and it sounds like the tune still has to be fiddled...which if he is goign to be running the race exhaust at the drags and it makes more boost and power as a result of lower back pressure then it makes sense not to spend too much money on a tune for its street setup

Can you tell me what you have done with the air bleeding setup to the header tank?, ity looks interesting, and im curious to what you have done

thats the secret cooling system mod that gtr700 had blacked out in all his photos of his engine.(apart from the extra top radiator hose of the header tank.)

you cant run it like that if your keeping the standard six throttle setup. as it removes the vacume chamber/balance chamber from the inlet.

ie: no vacume take off points.

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      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

      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.

      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. 😂
