Posted March 6, 201312 yr comment_417011 Anyone out there have any experience in the whole RB26 head / RB30 bottom end with trumpets???Saw it in a mad Z in speed hunters and liked the look of it. Just want to know if its stupidly expensive. Been doing a bit of reading on forums so I kinda have an ideaBear in mind I reckon I can handle a L24 because I have a manual, but this would be WELL beyond me!Ideas???

March 6, 201312 yr comment_417012 rb30/26 combo has been done alot, more turbo then n/a though. Kid k has a 25 in his so would best to ask him. From memory rb30 are tad taller thne 20/25/26 but custom engine mounts will deal with that Link to comment https://www.classiczcars.com/forums/topic/45933-random-engine-ideabeware-possibly-very-dumbexpensive/#findComment-417012 Share on other sites More sharing options...

March 6, 201312 yr comment_417016 I think Ben from Otomoto is building an RB30 with a twin cam head for his 240K Coupe.You could ask him for some info.

March 6, 201312 yr Author comment_417019 Really? Might have to look down that path. Thanks mateI realise its doable, just wondering if its possible on a budget Link to comment https://www.classiczcars.com/forums/topic/45933-random-engine-ideabeware-possibly-very-dumbexpensive/#findComment-417019 Share on other sites More sharing options...
March 6, 201312 yr comment_417059 I can't see it being a terribly difficult conversion. 26/30's are built all the time. I had a chat with a good mate of mine who owns a nice GTR workshop when I was thinking about this and he recommends the 25 head over the 26 head though. The 25 head has VVT on the intake side which is better for N/A power. I've seen HKS VCAM set up's on 26's but pretty sure they are not made anymore.HKS - V CAM System - Step 1 A & B - Nengun Performance Link to comment https://www.classiczcars.com/forums/topic/45933-random-engine-ideabeware-possibly-very-dumbexpensive/#findComment-417059 Share on other sites More sharing options...

March 7, 201312 yr Author comment_417087 Yeah I read that. Awesome build. But he did it himself so saved heaps, just cost him time. I was just mulling ideas around in my head and thought of this. I really love the look of the RB26 head though (I'm in love with GTR RB26dett)But I don't want to go beyond NA. It's how they were and I want to be true to that, but chase HP at the same time. I wonder what the cost comparison to a 3.1 stroker would be?
