Rb30det Stagea 5spd. Sleeper Powerhouse Wagon!

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)

So have a read of that also.

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