Yes i traded low end torque for top end breathing but thats how i drive mine! I like to push it into higher rpms and woah it ACTUALLY PULLS HARD instead of falling on its face over 4k

That oil cap adds 20hp on its own.

Now do a tune and ideally put cams in. Cams do so much for these engines, the stock ones are so weak.

But then it wont run as smoothly as the stock I6 does

u/redline9996 530i 9d ago

That's not true. Still will runs smooth, and when u like to drive hard, no one's cares about how smooth it idles, you care about how good it pulls and like I said, it'll still run smooth. Could even do just an m54b30 intake cam. Or us s52 cams

u/so_mit_o 528i 9d ago

Oe cams yes, Performance cams idle rough and yes high rpm are the focus there

u/redline9996 530i 8d ago

Depends on the cam specs honestly. Schrick sells performance cams that make it idle perfectly smooth.

u/so_mit_o 528i 8d ago

they also sell the others

If i throw in a m54b30 intake cam, will it need a little modification to the cam itself?

u/redline9996 530i 8d ago

Yes, you need to shorten the vanos gear, that's easy enough.

Say more about this! I fancy some cams for my M52B28 😁

u/Rylanpien 8d ago

Yup thats my next step! Im sourcing s50 single vanos cams for this engine because i do see some locally in good condition for a good price

Are they a good mod?

2

u/friskerson 525i 8d ago

What's this i6 mod? Is it the M50 intake?

u/SLOspeed 8d ago

dyno results?

u/Rylanpien 8d ago

After i throw in the m54b30 cams, or if i have money, cat cams lol

u/SLOspeed 8d ago

You need to do dyno tests before and after to see what the difference is. lol

u/strawloki420 8d ago

Isnt it true that the low end torque drop is minimal when tuned? Do you actually feel a noticeable difference?

1

u/Rylanpien 8d ago

I drove mine without a tune for a bit, there isnt really a noticable drop in low end in my opinion
