Well this is the deal. We have been working on and EVO 8, It seem to be bucking at high RPM's and the boost was at 12PSI from the time they replace the lower block of the engine due to insuffent fuel problem it made one of the cylinders or pistons egg shaped. Mitsu told the owner this. They did cover it under the warrenty. Now this car was a buy back once and before it was bought the secound time it had already had the engine and the tranny replaced with an 04 tranny and motor. Next not even a year later after owning the car the botton end had to be replace because of a defect. Now about 6-7 months later the car seems to have a blown head gasket, the turbo seems to have to much play, and the car blows white smoke when you get on it a bit. Now one of my worker's called the dealer and we setup a meeting for monday at 10 am they are going to look at the car at 9 am and meeting with me and a few from my little shop and see what we can find out. Funny thing is the dealer told one of my guys on the phone that the car shold not have bee drivin hard for 7 months. Car was running off waste gate pressure the whole time 11-12 psi. Oh yeah car is stock, besides turbo timmer, two gauges boost and A/F,filter.

Dealer told us on the phone that he could look at the ECU and see if we were driving it hard. Is this true? Also the head tech told us the car does not run 19 PSI. LOL AHAH I have 6 pages worth of Information from here and online about the car, and pages from EVOM to help out. If anyone has information on the car that would help please send links, wish us luck.

 

If the ECU hasn't been touched then you shouldn't have an issue. The only thing the ECU logs is error codes right ?

Unless is says in the User manual not to dirve the car hard for 7 months, tell them where to stick it !! Hehe, but no, it should say X amount of Km's to run the Engine in, so if that was followed, you should be fine again.

Don't mention boosting to 19psi......as I'm sure they'll try and blame you for it to get out of possibly another expensive rebuild at Mitsubishi's cost.....

 

the ECU has not been touched, does anybody have information from mitsu on this car?

 

Was the vacuum line still attached to the wastegate actuator?

Running lower boost than stock isn't a good idea either because the ECU feeds fuel based on boost/airflow.

There is no "abuse history" in the ECU so don't worry.
