hey guys,

ok so first, got my rb25 running in my r32 today, on cold start it idles at 1000rpm then on hot it idles at 500rpm but if i rev it and let it drop it will stall, so to adjust that do i just wind out that thing with a brown plug? under the purple acc valve? i had to replace it as the brown plug was broken so i just wound it all the way in,

also with this as i put the revs up a bit with the accel cable, as soon as i move the tb a tiny bit i can hear a lil click? is that the vct? im guessing it is but if any1 can run out to there 25 and start it and test this? if not what could it be?

Then with the thermostat, i had to change some welsh plugs on the thermostat side so i took the thermostat out, when i started the engine today i let it heat up, (left both bleed valve screw in and radiator cap) as i wanted to see if i fixed the welsh plug, didnt want coolant going around the welsh plugs i replaced,

so the temp hit 90 on my defi gauge (sensor is in top pipe) so is either my thermo stat gone? or is it because of air lock that it didnt open up?

o also while im at it,

could i get part numbers for:

thermstat (if i need 1)

Ps belt (series 2 stagea motor) (3PK belt)

i think thats it, any info would be good thanks,

Cheers JV

ok guys, i ordered the belt, i ordered a 3pk855 which should be fine,

thermstat should be fine to with a bleed,

just need to adjust this idle,

the colour plugs are purple and brown, the brown is the acc and the purple is the one my mate told me to twist out to bring up the idle, can any1 comfirm?

ive uploaded pics to so you can see the plugs,

Cheers

with engine warm you need to disconnect the tps sensor and adjust idle screw at back of iac assembly to 600rpm, then reconnect the tps and idle should be correct.

that is the basic run down, i have posted full procedures in the past.

only on the early rb engines you disconnect aac valve plug, rb25det is different procedure.

also the nvct is activated/advanced off idle, so yes the clicking will be the nvct solenoid.

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
