i had that same problem with my RB25DET mate.....my problem was that my Harmonic key was rooted....it was advancing and retarding timming as i was driving it.....and my revs were doing that as well....it would jump up and down rapidly on idle......so might be worth checking that....i had to replace my motor...goodluck

My R33 was sluggish and i had the cam angle sensor turned left (counter-clockwise) and it increased response and power (10rwkw extra). Did it on a dyno- best way because you can measure the changes to the power curve. Turning yours right might've made it worse.

It's something else you've missed i reckon. A smic swap (i've done the R34 one too) shouldn't do anything other than allow more charge to flow through the intake.

yeah i had the r34 cooler in... then i swapped back to the stock smic cuz this stupid problem.. which i cant figure out what to do...

when i turned the cam angle sensor as far clock-wise as possible it made more power and even more drive ability but its still nothing like it used to...

engine has around 90,xxx kays on it..

only has a pod and turbo to tip zorst..

changed plugs for brand newies around 1000 kays ago..

do oil and iflter every 4000 kays,,

suck a f**king annoyhing thing..

i dont understand whats the go with this ecu diagnostic shit..

their is a tiny red and green led light on the actuall ecu.. they flash and shit when i turn that small screw all the way clock wise o the ecu..

the cat temp sensor light in the dash flashes on and off..

i dont know how to decifer them fault codes and that... what to count and all that :S

im shit i know

haha

cheeeeers

search the forum for ECU+CODES

there was a thread with what each light flash meant.

also, I'm thinking that if all this started with the SMIC install, are you absolutely certain the the 2 rubber joiners for the cooler are not cracked.

have you removed both off the car, cleaned them and thoroughly inspected them?

remember that those rubber joiners have probably not been touched for about 15 years and perhaps as you removed the stock cooler (the pipe has a lip on it) it may have cracked the rubber a little or enough to cause a leak.

it's free so might be worth checking.

mate seriously.

search.

I just typed in ECU+CODES just like I told you to do...

and look what happens..

Now look at the 6th thread down.

Now look at the 3rd post.

surely you could have done this yourself.

haha yeah rb20 slug.

took it to a local work shop but they could not find a thing wrong with it... no ecu fault codes showed up...

well when i was playing with it in my driveway it turned out to be the plug for my cam angle sensor was rooted and my timing belt was possibly put back on wrong as if i tried to back the timing off anywhere away from as far advanced as it would go the car would start doing the eratic idle....

i have just brought brand new gates racing timing belt and have rb25 turbo and greddy front mount to go on soonish along with a speedlab ecu remap..

cheeers for all your help guys :)

yeow

      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.

      Looking for someone with a R34 front bar

      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. 😂

      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.
