325i with 330 intake and decat
Does anyone know someone in Cape Town that can map it for me?

325i in SA used N52B25 engine. I'm not sure of any retrofit of intake manifold.
In US, 325i used N52B30 detuned engine. Hence with 330i intake will increase lots of power with ECU tuning.

That would be a bummer, I'm sure someone here suggested I do it

RE: 325i with 330 intake and decat
I have been digging the Internet for some time to find out and nothing comes up with the n52b25 engine, it's only the 325i with a detuned n52b30 that have been retrofitted. It also has me wondering if it is possible to retrofit the 3 stage disa intake manifold from a 330i, but then the map settings probably won't work due to the different displacements in the engines, therefore the air/fuel mixture might not have the same effect of performance. But I'm sure skilled workshop can probably create a perfect map setting for the n52b25 engine instead of using the n52b30 map setting.

Lets see, if it's a bolt on I will try and make it happen otherwise there will be a 330i intake for sale

Well, I have the intake with throttle bodies and some cash to spare so if anyone is keen to take this journey with me I would be very interested provided obviously that it's a direct bolt-on.

Let's dyno as-is and apply the mod with software and see where it goes.

If not I reckon the 125i guys who I believe had the 3.0l engines may be interested in the intake.

It will bolt on. On the outside, the n52b25 is identical to the n52b30. The difference is the internal displacement.

RE: 325i with 330 intake and decat
Well then it's a simple matter of engineering and maybe a turbo

Doesn't look like I will get any traction, what can i expect for the intake if I sell it?
