mivic shaft

Wondering about the mivic camshafts on the 4g, i keep hearing their slightly more aggressive. im a lil worried i might break something the first five mins of driving... what are the cons of an upgraded shafts,what can happen?? should i get matching stock valve springs? and cam gear...

pretty sure its a garanteed check engine light :?

i'd bet 100$ the springs, retainers, and cam gears are all identical.

if the cams are more aggressive, then it woudl be a drop in affair.
since the car has a MAS, it will automtically adjust the fuel maps for the cams.

i doubt it would cause a cel.

but i think you woudl want to be sure of this before you start popping rockers

I'll check CAPS for any differences in parts numbers...

For the 9th gen:

Camshaft (RH): MN149841
Camshaft (LH): MN149842
Valve spring: MD163357
Retainer: MD159209
Cam sprocket: MD313741

And I just realized I have no info for the 4th gen Eclipse :(

Edit: From what I can tell from Mitsubishiparts.com the part numbers for the springs, retainers, and sprockets are shared among all newer V6 Mitsubishis.

Edit: Okay, the springs for the newer Eclipse are a few dollars more expensive than the ones for the Galant. As far as part cross references, the valves springs from the Galant are NOT compatible.

fuck yes!

the cams on the 4 cylinder Mivec engines should be the same for the galant and eclipse.
the MIVEC cams from the V6 eclipse will not work in the regular 3.8 liter galant engine.
the MIVEV V6 in the galant ralliart should be identical to the MIVEC V6 in the eclipse.
