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

Does N52B25UL 753082806 from E60 2006 523i also works for 328i->330i?
From photos it has 2 hoses at the bottom.

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?

I will have a manifold + disa and possibly ccv for sale soon, am located in Canada, Montreal area, anyone interested?

Car is probably getting totaled out from rear end collision.

I'm in Ottawa, on if you have that intake for sale I would be more than happy to take it

It's already gone.

Good luck!

[Arturas]

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

[vilord]

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

[Arturas]

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.

Read 6 posts up on this page; I have a pic showing the difference between the 2.5L and 3.0L manifolds

What's everyone doing for DISA valves in 2023? Bite the bullet and go genuine BMW from FCP Euro?

[Spence90]

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

[Doreen]

yes, it makes a lot of sense

I was cheap and got the ones that were $50 each from Amazon. We'll see how long they last. If I end up with problems I'll try the cheapest ones from FCPeuro, since they'll replace them for free if they go bad. The big DISA is easy to swap out. There's no oil in my manifold.

[vilord]

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?

I took a different budget approach and bought 3 cheap N51 manifolds with original DISA's from eBay and tested the valves with INPA.

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?
