Yep, and when I fitted my 30, according to the RB30 twin cam pdf guide the RB30 would be too tall for the R33 engine bay but I had no height issues, bonnet closed fine with no rubbing.

I think he was just pricing up his options mate.

Possibly taking advice... I suggested an RB30 would be much cheaper and better! (BTW  an RB30 fitted under my Stagea bonnet even with a top mount with no lowering of engine mounts necessary).

Ok thanks guys

yeah am getting ready to build a rb25/30 to put in once I get my licence so no rush so want to take the time to get everything right

kiwiRS4T how did you go about 30 swapping your ride

what trany, head, internals, ecu, harness etc did you use

The r34 mounts should work on the 30 in a 34

Stock internals, just rings bearings and con rod bolts. RB 25DET head retaining the VCT. Link ECU in the original case. Because the Stagea was AWD I got an R33 GTR gearbox but big box RB25 would be fine for 2wd. Stock manifolds would be fine for 500hp+

    • Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA
    • I'd want at least $40K for mine, but thats easy to say cos I'm not selling anyway.
    • That's incorrect. We have 4 seasons, consisting of pre winter, winter, post winter and a small glimpse of hope! 
    • I spotted a black C34 in Mittagong this morning!
