How about a manual boost controller?

 

pretty obvious there... powertrain issues.. you are increasing boost, thus stressing the engine beyond factory specs

 

A little OT here, but can the MBC be hidden or removed so the stealership won't see it?

 

hidden? nope... its taped onto the boost solenoid... thats the first place they will look if they suspect that the boost had been tempered with
removed? yes... but make sure you replace the boost hose also

 

Thanks Evo sky!

 

You guys got some good input here, other members are always curious to know what they can get away with. keep this thread going.

I'd agree, depends a lot on the dealer. I start from the statement that Mistu issued on warranty matters, which seems to say that if the mod is not related to the repair, it's covered under warranty. This, of course, leaves dealers with some discretion to make that call. It leaves us owners who want to have some warranty coverage left with the option of either no modding, or, for some, only doing mods that are easily reversible (I know of dealers, for instance, who will treat an Evo as stock for warranty work if simple stage 1-type mods that they know about are removed before the car is looked at for repair).

The Evo's a great car because small mods can generate so much bang for the buck. On the other hand, it's not all that shabby stock...sub-5 0-60, surefire handling, great responsiveness, and very driveable. (Incidentally, according to the latest Motor Trend, the 03-04 stock Evos will probably be about as quick as the new MRs due to a 5k launch rev limiter on the MR). So while it's tempting to think that for an extra $2-5k you can have a true supercar, I'm not sure it's worth the warranty concerns. Just my .02.

 

The best way to get around the warranty problem is by LIGHTENING the car. Go buck wild, and don't impact the mechanicals at all. If anything, the reduced weight will reduce shock on your driveline. There are two parts of power-to-weight

 

smoking out headlights cant void anything correct?

 

I think the Evo 7 lights shouldn't have any problems provided the wiring is correct and don't fry anything.

Lightweight batteries may cause issues since they may say that you're not using a battery that's to spec. But here's food for thought: the manufacturer's warranty do not cover the battery, or the tyres for that matter. So if the warranty doesn't cover the battery, should you be free to use any batter that provides an adequate output? Same for tyres.

I have a K&N OEM drop in replacement air filter and an oil filter. I'm sure they'll try to work up something about warranty if it ever comes up, but that's not right and they shouldn't do that.

Boost controllers are definitely not good. Dealers have given people hassle for that.

I'd be careful about haphazardly ripping out parts for the sake of weight-reduction. If it's trim panels and such, then it's okay. But if you're removing structural braces, then you're asking for problems. It's not just a warranty issue; it's a safety issue as well.

Smoked out headlights may not seal correctly and will have condensation form inside the lenses. As far as warranties go, I don't think it should be a problem unless you also upgraded the bulbs to something that draws more current, or mess up the wirings somehow.

 

g6civcx thanks for the reply! does just going to the dealership and asking them if doing a mod will void your warranty ever work (if you bring your car to the same place everytime) or can anyone that works in the service department void ur warranty, so you would have to ask them all and trust them

 

Dealers will do just about anything to deny warranty claims. I think that we should find out which dealers have aftermarket-friendly service departments and give them all the business!.
p.s., you guys forgot tint

 

Don't forget, It is AGAINST the LAW for the dealer to void your warranty unless they can PROVE that your aftermarket part caused the problem. i.e your exhaust is not responsible for problems with your lights. check with SEMA if you need ammo against dealers
