Cheap/Basic M42 Mods.

[decay]

you ever driven an m50'd Car?
Did your gas mileage change at all?

I have not, but I'm sure it's not making that kind of power. OTOH the handling with a 4cyl and 225s is fkn awesome.

No noticeable change in fuel consumption.

The dbilas setup isn't cheap, but it is an easy install. Did mine myself and all I usually do on my own is basic maintenance like oil changes/brakes/etc.

It feels a lot like a hot cam does. Running mine with a MarkD 91-oct chip and an adjustable FPR.

I've been real tempted to go the SpinTech route whenever I get to exhaust. Sound clips sound wicked but not everyone's flavor.

Damn man, spintech's are chambered like flowmaster's. Not the best at all IMO for a 4 cylinder.

Definitely gains, but there are also issues with tuning and filtration and everything... for the expense you can have a good swap and get the power. It's more just unique in my opinion.

Yeah there is definitely a "cool" factor with it. Is it a expensive swap? What tuning is involved? Hmmmm, now I'm thinking..........

[JoeyBones]

Oh ok, are the gains there? Seems like that be a little pricey? Is there a kit out there?

Independent throttle bodies. Like the M motors have.

Sounds good...i recommended the other due to the tips already being there for you. the actual muffler design is actually the same though ;)

[honkey]

does anyone have a dyno for itb's on an m42? it would be cool if the gains were there.
