Thanks.

No, you don't need one. All you did is got rid of air velocity, now your engine makes less torque.

NO!! I need tune! I got this THIS THING to increase air velocity, so i definitely need tune.

P.S. HakenTT, you post just to increase your post counter?

You can't tune for that anyway. All you did is reduced the air speed that is going to the engine, now you are losing power and torque. Air is still getting choked by the small ms42 throttle body. You got to go with whole ms43 conversion to get full benefit.

Thank you very much for files Daniel! How yo knew i need them!? Or you are that guy from other forum!? You should be. Thanks.

HakenTT, why you think i don't know these things? No offense, but i ask for tuned map not for information what i already know.

Thanks.

I think the larger intake would increase air volume, not velocity. what adapter did you use to fit the m52 throttle? I would kinda agree that using the ms43 and larger throttle would be more ideal.

To be honest, didn't conversion jet, i just got everything to do this. Got THIS adapter. MS43 conversion would be splendid, but AFAIK conversion cost is half price of another e46 with ms43 fitted from factory.

I doubt it would cost much, a harness, gas pedal, and dme would probably be less than $150 from a junkyard. If you can get a 330i intake cam also that would easily bump your hp up 20 without touching the tune.

I believe there is need for more changes than only pedal, harness and dme. How about changed displacement!? MS43 never was never fitted on 2.8 engine, so there is no stock tune for that displacement.
About costs, part will cost approximately 200£ + my personal time to do this. Price difference between 328 and 330 is 300-400£. Definitely not worth.
Just got one more silly idea in my mind, what if i can find bigger throttle body from other bmw driven by cable not wire.

If a maf based system, the .2l displacement wouldn't make much of a difference.

Wait...HakenTT was right !!

by using the b30, you lose air velocity, that's technically true...

...unless you fit exhaust mani,catless, conic filter and a map too (cherry on top would be cams)
the more air you give, the more air you need to expell that's how you balance the ratio...

for sure the only intake manifold will give gains at high rpms and small loss of torque on low(...a shorter diff would give you back that torque kick), but it doesn't means that a MS43 Ecu and a dbw throttle mod is mandatory to have a proper working car..

i'm about to do my conversion (still have to collect last parts for ccv&Vanos) and i've spent the last year reading pros&cons of this, the 330 TB is useless as the 330 injectors: the difference in the diameter from 328 to 330 TB can't be considered as a restriction and the difference on the injector's flow will be tolerated by dme auto adaptation or modded by a custom map.

his signature explains so many thing....

i'm with daniel f.

After a bit of research didn't find any proven info of gains from this conversion. Look like best idea is just sell manifold with TB adapter in ebay. To much hassle for minimal "theoretical" gains. Will leave engine as it is, and if that car will become fully track car, will swap to some v8 or turbo. Thanks for replays.

I wouldn't give up just yet...

I love ignorance.

Do you think it's possible that with almost 7000 posts & over 6 years that "maybe" I might know things & have first rate contacts ? You need to realize that I was trying to help you, hmm, maybe my source was once a very knowledgeable E46 328 owner.....that had done exactly what you're trying to accomplish now.

My Ride: E46 328Ci Coupé
Same "Problem"

Hey guys!

This is my first Post so I'm going to introduce myself, I'm from Germany and I study Automotive Engineering in Landshut. I drive an E46 328Ci Coupe and I love it! I often read here before and now I thought it was time too register an account, too.

@daniel f.
I am going to do the M54B30 intake mod on my M52B28TU manual transmission, would you be so kind and send me the map too? That would be so great

Sofern ich mich recht erinnere hatte ich ihm keine Kennfelddatei geschickt, ich han auch aktuell nüscht in die Richtung. Ich glaube da ging es um eine jungfräuliche AD Softwareversion, so das er TunerPro und die xdf Datei nutzen kann.
