why? an RB25 is superior in every way and I'd even argue an RB20 over a single cam 30.

or if you already have a 32 or 33 GTST why not just do what everyone else does and use your 20 or 25 head on the 30 block? much better option.

They don't make big power without a lot of work. The heads flow pretty well the same as RB20 heads so not much point.. slap a 25 head on it, then drop it in your skyline.

SO much easier to go the twin cam route when it comes to management and ancillaries, keep what is suited to your car. I used an R32 RB25DE head which meant EVERYTHING that was on my RB20 swapped straight over to the RB25/30.

they dont make power? WHAT!!??

i had a 12 second vl before i got the r32 i currently have. the whole setup owed me no more than 2 grand and it made over 200rwkw with a standard computer and an untouched non turbo rb30. i have a mate making 380hp with an also completely stock non turbo rb30 bar a head gasket and cam. i also have another mate making 400hp with a stock turbo rb30, just has a cam and valve springs.

im not trying to say they are better than a 25, but they make power just as easy, and have an extra 500cc! and in my opinion are alot more simple and easy to work on. yeah as a vl owner i guess im just more biased to the rb30.

im thinking of doing it cause ive never seen it done and it would be something totally different. obviously the long term plan would be a single cam head for when i want to make some really serious power

like it or not - they don't flow without alot of work to the head. I had one in my last 31 RB30e + turbo and it was great (for what it was)

great for up to 250rwkw in a dirty 1, but in a jap import skyline...why?

If you were going to all the effort you would put a twin cam RB30 into it like most people do.

Spending all the money getting a SOHC RB30 into there is just pointless, hence why people don't do it and why you wouldn't see many. You would make more power, spending less money on the current engine in there than the engine swap just for the sake of "something different".

what would make it so much harder to do a single cam rb30 than a twin cam?

Nobody is saying its easier or harder, Just pointless. Do you seriously thing the single cam head is going to flow what the twin cam can do.

lol no one would put a rb30 in a 32.... single cam... thats just stupid

You say that but there used to be someone who drifted a R32 with a RB30ET in Perth...

Pretty sure he must have come from the east though, I don't know any West Aussies that would be that stupid!

So to the OP, yes it has been done but no don't do it because it's a shit idea :cheers:

      Shoota's R33 GT-R RB30/26

      @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.

      R33 fuel setup

      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.
