So what would need to be done to build an RB30E block to take an RB25DET Neo head?

The car inquestion is a 5spd stagea RB25DET Neo, running perfectly fine, and looking to rebuild it, seeing as how RB30 blocks arent hard to come buy i figure i'l do it properly and start from the bottom up.

The idea im hoping for is to drive the car around as is, while building up the 30 bottom end. Then, once its built, basically remove the manifolds from the Neo in the car, pull the engine out sans gearbox, remove the 25 head, mate it to the 30 block, change to a stainless turbo manifold while its out, put it back in and tune it via R33GTsT Power FC.

Basically, id like to build it so no modifications need to be done to the head in order to mate them together. Build the bottom end to suit the top. What should be my reccommended shopping lis, from those who have done it?

Is this feasible? The stock Neo runs about 190-200kW? Im aiming to end up with about 350+ from this combo, using a larger turbo, injectors, pump, regulator, cams, and any other supporting mods i may need.

I have read through a few pages of dyno results from hybrid engines, as well as the 300 page thread that started of about pistons.

refer to the RB30 conversion thread; has all the answers you need ;)

Having said that, you'll need to marry the gtr style sump to the rb30 block.

It may be easier to buy a blown rb26 and build that up slowly.

As mentioned, i read through a lot of it and its hard to get a solid list from SIX THOUSAND POSTS due to its just a whole lot of different peoples suggestions and parts of their combos. Cant just take a bit from one engine and a bit from another, can i. Plus, its 6000 posts, did i mention that?

Im after info from those who have done the conversion, from start to finish. Otherwise it gets a bit jumbled using different bits from different peoples opinions, and things dont match up very well when you do that.

Yeah, there is a "in thread" search button.

Have a crack at using that.

Also the 3ltr for a GTR applies to you (except the head, thats covered in the R33/3ltr thread)

http://www.skylinesaustralia.com/forums/Rb...on-t106224.html

So have a read of that also.

Everything you've asked i know is covered in the two threads as ive read it all ;)

      "Cheap" bolt on turbo on RB25DET NEO

      @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
