Hey folks I'm looking for some info and wanted to see if anyone might have it. Working with a RB25DET Neo and I need some factory engine internal specs: 
deck height
Cylinder bore
Piston stroke
Crank collar specs..
Honestly any factory internal specs for the engine. I'm going over it with a fine tooth comb to make sure it's a solid block before I start building it.
 

I have found a manual but it's in JapaneseNissan Skyline R33 Service Manual.pdf

You won't need a crank collar unless the crank is damaged. Bore and stroke here:

It has 3 different specs though... Not sure which one is good?

    • Hi, does anyone know how I can, or can a moderator remove this advertisement please.  Has been sold a long time ago and would like to remove references. Thanks. 
    • 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 
    • 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?
