Was having a look online and read a few places that a rb30de engine as long as it's series 2 is fine to use for 30/25 turbo build so long as you change the cams and pistons as I was going to anyway. Is this true because if it is my mates got a spare rb30de s2 with water and oil lines already that I can have so would save a bunch of money on doing so.
 
Cheers guys.

You can use stock pistons if you are poor. I think you'll find the cams are in the head.

Will probably upgrade pistons just because it'll all be apart. And yeah, was a copy and paste from vl forums. :P

You don't need water and oil lines if you are just going RB30DE, the water and oil lines are just for the turbo.

Going to be turbo. Only just got into the planning phase so still doing a fair bit of research and planning out the go.

Once I've mapped everything out as far as all parts used for certain components I'll do a write up and can get critiqued on the optimal way to progress towards my goal.

 

End goal is MAX 500RWKW, tuned to say around 350ish - Want it for Race Days, Street driving/weekending occasional weekly use.

Right your thread says RB30DE so was confused. No way 1000cc injectors and a 3076 will ever make 500kw but will do 350kw no worries

Yeah, I changed to just aiming for 350kw. More reasonable for my budget and my first build. The only thing I think I might change from that above list is just getting some upgraded cams, from what I've read and seen others do they've achieved my numbers with a pretty similar setup. Do you think that the listed above build will be pretty reasonably reliable at about 350kw?

If you buy a neo head and intake you'll save money on the reg and fuel rail plus all the other benefits like solid lifters.

My fuel system is maxed with 1000's and walbro 416, change the 044 pump for a bigger.

Going to use the head and any other useful salvageable parts from the engine from the car I buy 33 gts-t.

I think i am going to go with the option of doing it right first, it's going to be in the build phase for a long time since I can't drive it anyway for another year so there is no rush. So It's going to be well worth it when it is done.

      There are adaptors that allow you to delete the booster and use an s15 clutch master cylinder.    if you want to keep the booster they are still available brand new

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I visited again today: It would appear they have painted the main body of the car and some parts of some of the panels, so I can say that I now have BMW parts in my car, much to the envy of @Dose Pipe Sutututu It is still covered in dust which is quite the tease but I did look at a few circumspect spots that will be behind bumpers and such and wiped some dust away: After my repeated begging to PLEASE DONT PAINT OVER THE ENGINEERING CERTIFICATE (you have to re-engineer the entire car if they do) I see THIS: Which is great. Excellent job tbh at least to me. A better non dusty example would be the backs of the doors that have been painted: Giving a reasonable contrast between old and new (I know the old isn't clear coated on the inside of doors). The door card will well and truly cover where the old paint is, you can see in the second pic some of the black butyl/whatever shit is sticking the plastic sheet behind the door transfer that has happened since it's clearly been stuck back on. The most maddening thing about this colour is every time I saw it in the wild it looks like another colour, same with photos of many cars with the same colour looking wildly different in every photo anybody ever takes and this is no exception. But stand a little further back and it suddenly looks dark AF. I did tell them when I was discussing which of the 70 million charcoal colours to choose from (a porsche one, a BMW one, or a R32 GTR one etc) that if they just ignored me and chose one at random I would probably never notice. Maybe they did. But the colour is supposed to be B39 (BMW Mineral Gray). Boring I know, but the R34 sedan (to me) really shows off it's boat-ness when you paint it in a bright colour like bayside blue or white or whatever else. I do have a fondness for AR2 Nissan Red, but decided against that because it'll have pretty odd contrast to random bits unpainted (like engine bay, bits of trim etc, and maybe it'll fade). And people will always fkin comment on AR2. Everything remains super dusty. I have tracking numbers for the new heads, as well as some Improved Racing goodies, but they probably will be a next year thing by the time they end up on the car. I did some maths on the heads and I know why nobody goes to this extent in Australia, because it's really not worth it, given I could have just CNC'ed my current heads, bought a FAST102/TB and used my current rocker/spring/cam combination and get a 383 stroker (or stroked a 6.0 GenIV bottom end to 6.6L) built for the same price of just the setup in the mail/on the floor here. Or I could have bought a LS3 and a Drysump system. And then have a complete engine to sell. Oh well

      We just disconnected the vacuum line if I remember correctly, booster is still there. Is there a rebuild solution for the booster or a different adapter that will work for GTR chassis?

      Yeah 4wd (boosted) has a recess in the firewall for the booster, and 2wd is flat - the example in the link shows the flat surface. When you deleted the booster, did you just attach the factory slave cylinder directly to the recess in the firewall with no adaption?
