Hi,
I plugged in the small disa, and when I press the gas pedal it does move a little at about 4500rpm, but it does not shut completely. With inpa I had trouble, but it does make it move a little every once in while. Does that mean it's shot? I did not update the ecu yet. Thx, David |

I mean it'll bolt on, but the 2.5L manifolds have smaller diameter runners than 3.0 versions

Thanks, I will use N52B30OL then, not sure which car it came from, but that should definitely fit correct?

Can anyone please elaborate on this?
I run european e90 325i 160kW '05, on a pillar B there's indication it's equipped with N52B25A which is ok. But I've looked into my intake manifold it clearly has something DISA'ish things on it. As I understand, it must not have these flaps since it's 2.5L. If not DISA's what is it then? Not su much familiar with BMWs |

You do have a DISA manifold already. 2.5 did get it in some variants.

Thanks for reply. If there're DISA's, then couple more questions.
- Does that mean I have physically same manifold as the one found on 3.0L 190-200kW versions? - If the answer is yes, going further, does that mean it's enough to have current ECU flashed/mapped (or even replaced with another sourced from 3.0L together with CAS and key) to reach more than 160kW? I know I won't reach 190kW since it's 2.5L but heard rumours that even 2.5L versions benefit significantly. |

Most people recommend genuine only on disas just make sure any oil from ccv system is sorted or they'll keep failing

EDIT: Update, I've replaced my $50 Amazon large DISA twice now in 3 months. I lucked out and found some OEM BMW ones from a u-pull-it yard that were in excellent shape, 2018 and 2017 dates on them. Car runs smoother for sure with the OEM ones. Last edited by firesnatch; 10-21-2024 at 09:28 AM.. |

my small disa is apparently failed, and has been for months... i should probably do something about this.
what is recommended for "any oil from ccv system is sorted"? catch can added between the valve cover and the PCV heater port?

Out of the 6 DISA's, I found 2 fully working (1 large and 1 small, thankfully), so I'm running those. If/when they fail, I might just convert to the N54 manifold. Gotta say the 3-stage torque is awesome, though. As is FCP. |

Question, please forgive me if this is question has been answered
Has anyone done any testing with the 3stage + euro intake box and a tune? ECS has the Euro N52 box which states being a "less restrictive" intake system, assuming this is true, would this not mean the airflow is 'freer flowing' and therefore able to take in more for the 3stage? |
