A mate of mine has a RB30 turbo the motor goes well doesnt blow smoke etc,but when the noise of the clutch fan stops you hear a noise when revving between 1500-2500 approx. a noise like a cross between big end rattle and noisy lifters,if you keep constant revs 2500 noise stays the same ,but on idle you cant hear anything ,motor sounds OK any ideas????

Does the noise stop when the car warms up, or will it do it all day? I have a similar sounding noise in my 33 but by the time I get anywhere to show anyone the car is warm and it doesn't do it anymore.

mine does the same as you R3AP3R, its just the hydrolic lifters

Yeah, mine's a weird problem. The noise stops and starts depending on throttle position (and even that varies). I can be maintaining say 2000 rpm in 2nd and it will make this noise, if I back off the throttle completely it may stop, or if I slightly increase throttle it may stop. Then it may stop and start at various times again depending on how I'm driving. After a few minutes (and it seems to be lasting longer over time) it will stop completely. I'm assuming this is because something has warmed up sufficiently.

I would have thought lifters would have been a constant ticking who's frequency would vary with revs, but be continual until it got warm.

It doesn't seem to cause any performance problems, it just sounds like crap and is embarrasing.

Don't mean to take over this thread, but I think we may be having similar issues.

they dont cause any performance problem for me etheir, the main reason i want to fix it is because it is embarrasing (most people dont notice though because they are rather quiet, only loud when i first start the engine when it cold)

those of you with lifter noises, have you tried a different oil?

I have a Mitsubishi Galant VR4 so I KNOW about Lifter noise.

Mine has reduced heaps when I changed to Motul 4100 TurboLight oil.

Cost = $39.95 for 5L

I bought mine from Autojoy at Burwood Westfields.

It is fully synthetic, and seems to be heaps cheaper than other synthetics I'ev seen/used.

It might be worth a try for you guys too.

    • @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣  
    • I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia. 
    • Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.
    • I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).
    • As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
