Hi All,

I have been asking around performance shops about my question. I wanted to know whether the manifold mounting for NEO RB25DE is identical to the NEO RB25DET, RB25DE or RB25DET. ADVAN Racing performance have told me that the mounting on all RB25 series are identical. Can anybody help me?

haha the magic question :)

Yeah I stuck an R33 manifold and turbo on my one....but for the love of god get a MOTEC or Power FC or some sort of computer that is fully programmable...the 25GT ECU is a complete bastard with piggyback systems.

so the r33 manifold will simply bolt on my neo rb25de, what set-up have u got on urs if u dont mind me asking....any suggestion on how i can put together my turbo...what would be the simplest conversion for now?

Thanks

Are you saying that it is possible to use the Power FC ECU for RB25DET in the Turbo converted NA car such as yours?

Yes it is...I'd go as far as to get the power FC for the N/A actually, unless the GT-t version comes with a MAP sensor...as chasing up the MAP sensor from a GT-t is getting to be a headache! But apart from that it just plugs straight in!

I am considering an R34 RB25DE (from an R32 GTS4) and I guess I'm a little worried about going from a turbo to non-turbo. What power does an RB25DE run at? Did you guys think it would be enough for you and it wasn't?

I never thought the RB25DE would be enough power :P Just when I bought my car a long time ago, the price of a GT-t was still in the $60K+ bracket so the 25GT was the only option for me to have an R34.

They deliver around 147Kw, so not what I'd class as amazing, that's why I put the turbo on my one.

Can't speak for anyone else, but for me, it was about buying an R34 for a decent price. The RB25DE still has a fair bit of poke due to the NEO, but for me, I had to have a turbo, so I swapped on in.

    • Wow ELVIS. You have an....interesting approach to conversation. Did you not notice that I wasn't talking to you?
    • Hello Liam - HA - somewhere in flies - possibly I have an update, but I have been so busy, projects have taken a back seat to getting business back on track.  I will let you know the outcome, but I think I am going to go for the 8HP,  CHEERS.  ELVIS
    • Thanks Joshuaho96, yes - as someone else also suggested, the 8HP seems the 'smart choice' - HA - and ZERO to do with cost, but I am sure 8 speeds will be better than 6 speeds - HA - maybe.  I will purchase a new 8HP,  Thanks.  ELVIS.
    • Nobody said anything about getting a "...cheap Falcon box..."- it was JUST a question about a specific transmission.  And YOU may have a problem with not enough $ - HA - I do NOT - so please keep your comments like you are some financial guru to yourself.  BUT - much appreciated re the cost of a new 8HP and I twill probably be the way I go.  Thanks.  ELVIS.
    • Most people I know in the BMW world are swapping 6HPs for 8HPs. The 6HP has a big issue with one of the clutch drum bushings wearing out shockingly early which leads to them going into limp mode going into 5th/6th gear as the oil pressure loss from the worn bushing causes clutch slip. Even with the adaptations in shifting the TCU can't bump line pressure enough to keep the clutches from slipping and burning. I've personally looked at a 335d with 6HP28 with one owner and ~90k miles on it and the transmission adaptations were way out of spec and even though it nominally drove ok I'm confident it would have needed a full rebuild sooner than later. Other than that they're fine, but the 8HP doesn't really have weird issues like this to my knowledge and they're in everything these days so pulling them out of crashed cars isn't too hard.
