First Mod: Headers or Shark Injector?

[derbo]

3.46 makes the car what it should be from BMW. It is slightly slower in the 0-60 category because you have to shift to third to make it, but both second and third gears are a monster and the overall 1/4 mile times are better by .3 seconds. And passing on the highway no longer requires downshifting to 5th.

I agree. 3.62 is even more fun haha.

Are you considering a full header-back exhaust? Cause it feels like a bottleneck will be your exhaust if you get headers. In California, I have issues with dealing with smog check. I personally would go with a eurocharged tune so when you do get the headers, you can get a new tune again for the headers.

I love my Shark but I will admit that when I do my headers I will be switching over to a Eurocharged as well for two reasons.

First being what Dane said that it will be customizable.

Second being that Conforti does not offer a cat-less tune for the 330. So you will get a check engine light.

Every time I talk to Turner about this I get the same generic answer of "a new file for headers is coming soon", it's been almost a year and I keep getting the run around. So bye bye Shark and hello Eurocharged.

So now I am in a real pickle, cash is available for intake or headers. I just have to pick one. I'm leaning toward intake for three reasons (what do you all think of my rationale?)

1. Super easy install (unlike headers which I have done before, but still takes 5 hours)
2. No CEL
3. No obnoxious sound and will compliment the software when I get it. If I like the gains, I may stop there and not go the header route due to noise, smell, and general hassle.

My point is, of all the mods I am more on the fence about the headers than anything else, I just don't want to destroy daily live-ability just for 10hp. So maybe starting with the other things is better?

Thoughts?

I agree with your logic. I would love headers but don't want the CEL and potential hassle involved with that. Not to mention headers with high flow cats are stupid expensive

I agree as well which is why I have everything BUT headers even though I consider them everyday.

Personally I think an intake is a great first step.

Performance changes with and intake or a tune won't be massively noticeable.

But the sound coming from an intake is very noticeable, very intoxicating and worth every penny IMO.

Sway bars and Z4M offset thrust bushings

Sway bars and Z4M offset thrust bushings

What do the z4m offset thrust bushings do? I don't even know what those are... sorry for being a noob. I have sway bars, and am all about handling over speed (first).

They increase caster in the front wheels.

I got the idea from my buddy with an E30 325i who put E30 M3 offset bushings on his car, then realized the Z4M ones work for us in the same way

More caster gives you more negative camber on the outside wheel when in a turn, without giving more negative camber when going straight or braking. This should in theory give you better front-end grip when cornering without accelerating inner shoulder wear on front tires. Only possible downside is more steering effort at speed and offset bushings move tires forward in wheel well.

I'm thinking of upgrading my camber plates to get more caster.
