330 Manifold and T/B on a 325 w/ supercharger. Yes or No?

[Focal E46]

I searched but couldn't find an answer or opinions.

With a larger manifold and throttle body, I would think your boost would drop resulting in a lower PSI. This is just me thinking "worse case scenario."

Thinking positive. Now I've heard of 9.5hp gains. Is this something would greatly grow in a SC application?

I'm a noob to FI so let me get this out of the way. My filter for the VF kit is a lot smaller than my K&N FIPK filter, wouldn't a larger filter be better or is it just small because of lack of space??

Thanks. :hi:

You can use the b30 manifold and make an adapter plate for your b25 TB. Although you might lose some psi, you should see HP gains anyways.

There are definitely gains to using the B30 manifold and TB. On one B25 race engine with a stand alone ECU, a B30 manifold was added and gains were over 20rwhp. Keep in mind on that engine, a LOT of other things were optimized and the quality of the tuning was well above average. Personally, on a 2.5, I'd change the manifold before doing headers.

If you need a 330 manifold and TB let me know. :hi:

Hey....I could always use another manifold to play with. :P

Just out of curiosity, why the TB too....I thought you re-used the stock TB with the TS3.

If the 330 manifold fits my 325 without any major modifications... I am interested in one. What all would I need?
