G'day,

I have a VL commodore with an rb20det out of an r32 GTSt in it. When i start it cold it idles fine, around 750-800rpm, but once it warms up it sits between 1500 and 2000rpm i used to be able to drop it down by fiddling with the black box on the throttle body(I think its a throttle position sensor or something...) but it would then stall. I had the injectors cleaned, replaced the spark plugs and new coil packs and since then it won't drop at all below 1500 no matter how much i move the sensor. (except when its cold when it idles perfectly..)

Any help would be greatly appreciated (and i don't mean telling me to get a real car!)

Thanks

Pat.

    • Hi all. So one of my major issues at the moment is my rear turbo leaking oil on the exhaust (and the general area). I presumed it was the rock hard super old drain hose, which it was not. So now I am in the midst of removing the rear turbo to get access to the banjo bolt that goes into the turbo oil feed. As one of the previous owners accidentally? tore off the OEM oil feed hardline that reaches behind the turbo, they ran braided lines directly to the turbo, presumably PTFE. Now, regardless if the line has rubber or teflon inside, is it just generally a bad idea to do this? I imagine these lines get quite hot being between the engine, turbo core and exhaust manifold. I suppose it's not too far fetched to think the line may even have melted. I'd love to hear your opinions on this as as the replacement OEM hardline piece is 130 per unit. And cutting open the currently mounted line to see inside will mean I just have to get a replacement either way. So far I am hoping maybe the bolt just loosened or (god forbid) they forgot one of the crush washers.
    • If it's a factory 20de manual probably has the 6 bolt flywheel in which case the det clutches won't work as they're 9 bolt.
    • All RB push clutches are interchangeable. AFAIK, the 4cyl ones are not. Different flywheels. The RB small box is not identical to the 4cyl boxes. Just very similar.
    • Hi. I need a new clutch for my gearbox. It is a factory smallbox behind RB20DE NEO. What options do i have? If iam not mistaken the gearbox should be the same as in R32 GTST and Nissan S14/S15? I found some Xtreme Clutch Stage 1 for S14/S14 (i dont know if you know the brand) (UK) OR...is the clutch same as in the bigbox from RB25DET?   Thank you!
