RB30Classic

I've got the RB30DET PDF which is excellent by the way, but I prefer to get a couple of options before going out and spending a few bucks on a new engine. Thats why I wanted a lower power level than is obtainable but need the reliability. I get the feeling that what your saying is 500bhp is attainable and reliable enough for the petrol heads on this site to give a good paneling too. THAT WORKS FOR ME! Righto 500BHP it is then, may the gods of tyre smoke and petrol fumes be kind! I'm not after a 7500rpm red line but just strong power

Excellent thanks, are these engines reliable enough at that level of power with stock internals or will I need h-beam rods and forgies? this thing needs to survive the NZ targa so it'll be getting hammered for 6 days of road racing. plus all the other daft stuff I'll be doing with it. I don't want to build an expensive engine that's going to destroy it's self

Ow forgot to mention I'm putting this in a 1974 Triumph 2500. I'm having to change the running gear to mostly R32 skyline stuff so hence joining this forum :lol: an it's in NZ and its for the targa ow yeah it doesn't weigh much!

Fantastic thread guys keep it up. You've given me the confidence to take the plunge and just collected my donor RB25de today.and I'm on the hunt for a rb30e bottom end as we speak. So I'm going for the rb25 de head rather than the GTR jobbie. IT's from a 93 Laurel so I was wondering if it would have the same cams as the r32 or r33? the body is e-gc34 so which would it be as I'd prefer to use the cams from the r33 as the tommei list in the rb30_dohc.pdf(which is excellent by the way) show that these have the largest lift and curation of the standard cams. Can I use the injectors from the RB25de and afm or will I need det ones as I couldn't find a flow rate for the 25de injector listed (If there is apologies but the whole thread is alot to retain) I'm going for a mild tune only at the mo untill the whole thing has run in for a couple of thousand K then go for a R32 GTR twin turbo set-up. I'm still learning the turbo side of things at present so I'm hoping this will do the job for me. Are the twin turbos from a standard GTR the ceramic coated ones and are these good enough for a target of around 400bhp (I'm not greedy and the car this is going into is no spring chicken) Also I noticed today that the 7 second gdz1la GTR skyline here in NZ has the the cambelt tensioners oposite as per the rb30 block without moving the tensioners. Is the N1 spec block like that?
