Rb25de Internalised To Rb25dett

[CR34M]

Hey guys, this is just a question out of curiosity and something i want to work on from now until im off my P's so i can have all the parts (or most of them) ready to install down the track.

The question in simple is...What does it take to turn an RB25DE into an RB25DETT...i know theres a bit of work involved in doing this since its an N/A engine.

What are the parts list, price range..over $15G, $20, $50 overall? etc etc

What needs to be done to the engine first off to run the turbos?

Has any of the SAU members taken on this endeavour, or have they gone for full engine swaps?

And Lastly if none of the above can be answered properly then my next resort is going for an RB26DETT, and for that question its where can you buy a fairly new or newish one. (Ive seen the R33 RB26DETT N1 for 13G brand new. But i have a 34 so legally i cant go below the age of the car. )

Right now this is about planning and cost estimations.

Thank you to anyone that takes time out to answer these quesitons for me.

Easiest option for you is to save money while driving around in your fairly new non turbo skyline.

once off your P's, sell it to another P plater, then buy your self an R34 GTT.

Not worth the hassle.

Legally, you can only use an RB26dett out of an R34 GTR (big dollars)

you can also put an RB25det from an R34 GTT (slightly smaller dollars)

but then you still have the shit Brakes and gearbox (not sure if diff and suspension is any different - or interior for that matter)

Not that you will listen, but saving for a GTT is your best option instead of trying an engine conversion or worse still, rebuilding the DE block to be DET (or DETT as you say)

Internalised? Pretty much the only "non-turbo" friendly aspect of the DE is its high compression ratio. The cheapest way is to bolt a turbo/manifold/dump pipes all from a turbo model and a decompression plate between the head and block, change the ECU to a turbo models. You won't be able to go very high with the boost.

The other way is to get the DE rebuilt with forged pistons with a lower compression ratio, forged rods...not sure what else is different maybe oil pump?

You would need to upgrade the brakes to the GTT models, change the springs and shocks as I'm sure these will be different, the gearbox is also different I think - you will then need an engineer to sign off on it.

I would pick GTST's option. Too much hassle, just buy a turbo model later down the track. in 1,2,3 years time it will be cheaper. In the mean time learn how to drive with no turbo.

Also don't buy a $13G RB26...What is that? A 500 HP crate motor? Without doubting your driving skill too much, best way is to gradually go more powerful

have a look in the NA section its been covered in detail before

yeh thanks guys, i have driven a R32 GT-R before, my cousin has one, i know it snot the same but i can drive them quite well i have a passion for that stuff. And yes i know it would be expensive part of the costs = part of the fun redoing it but you are definately right, it is a hassel doing some of the things.

As for the brakes i am importing some big 8 piston caliper Brembos from singapore next year brand new front and backs done with a full new system. thatd cost around 4500, but thats one of the many things i wanted to do.

I guess when im off my P's ill probably buy a GT-R not a GTT, my dad was thinking about buying one but he would be the daily driver and i wasnt to keen on having our main car being screwed over, so i decided to sell my car (Holden VS) buy an R34 25GT and keep two cars in our garage still while having money later for a cheaper 34GTR, (or as i mentioned a full redo of the engine on the RB25DE)

anyhow thanks for the help guys, much appreciated.

Are you sure 8 piston is big enough

Just buy a GTR when your off your P's much easier.
