DAMM THATS SH$TY. . Well live and learn, now you know there are spies here!

 

nail/head

This was my exact thinking when rebuilding my car. Why would anyone, after having a major engine failure, continue to use the same weak parts that everyone is aruging are at fault?

So let's just say that Stew pleads his case and they warranty the engine. Then he will have to go through this all over again when the bearing/rod bolt fails again.

I say rebuild the engine stronger and keep the revs down. Again, this is exactly what I am doing.

 

I don’t know where this rumor is coming from?? So now EVO engine is weak and the parts in it are not strong enough... let me raise my BS flag here please


You have a car with 250 WHP stock and then we add cams exhaust and tune and end up with 350WHP that’s 33% more power on same parts... IF the car had 50WHP extra I can accept that but when adding 100 WHP expect things to break so don’t blame Mitsu at all.

If the car was stock he would have got his engine rebuilt for free and under warranty.

Stock parts are strong and are proven to handle power over and over again.

Again, very very few stock EVOs had engine failure.. I can’t even recall any thread.

 

Number one failure I have seen in EVO's.....rod bearings/connecting rods. While we have made 550 whp on the stock bottom end I have seen many fail with 320 whp or less. It is BY FAR the most common failure I have seen, by far.

The pictures of the combustion chambers you posted are clean of any detonation that I can see. I truly do not think it was that.

As for rebuilding the car I feel bad that it happened to you. Nothing on the car is from us so I have no obligation to fix it but would be glad to help you out of your mess and do the job. It is quite large as you have said and I am sure I can offer our top notch work at a discounted price. I even have some used transmissions laying around I can probably either steal the case from or sell as it is.

Good luck with whatever it is you choose to do with the car.

I understand that most people that own these cars are probably just getting buy with car payments, house payments, college whatever. To those people it is very tough to fix a $30,000+ car that you are also in debt on modifications on. The fact is Mitsubishi cannot be held responsible for anything that has happened to the car once it is modified beyond how they built it. I was lucky back in the day racing my 1991 Eagle Talon, I'd break driveline parts like pencils, I had a local dealer who I bought atleast $10,000 in parts from a month for resale that always covered the car for me. I even got a few block and heads from him. After the racing go really serious I quit asking or expecting this treatment as I thought it was unfair to Mitsubishi Corporate. Now with Mitsubishi being in enough trouble financially I think we all need to think about how much free stuff we want from them. If we keep taking money out of their pockets for our own mistakes and modifications there may not be an EVO X, there may not be a Mitsubishi at all. We have had 2 or 3 things fixed on our EVO's at the shop. Two were recall parts though, like the fan relay. I also had the transfer case on my RS warranteed. From the day I bought the car it was EXTREMELY loud, I couldn't stand it and got it passed through. There are 3 brand new EVO's at the shop that have been bought and that is the extent of the warranty work. There are another 4 EVO's at our shop that are still under warranty but will never go in for any work.

We have actually been discussing at the shop lately our Stage 5 plans. We did our Stages 1-4 the first year the car was out. We've added options and such but never came up with a Stage 5 or beyond. I really think Stage 5 is going to end up being head studs, rod bolts and a small gasket kit to do the job with. The connecting rod in the EVO is much stronger than the actual rod bolt from what I can tell from the breakages I have come across.

while this thread has wandered,
when an engine does melt down which cylinder shows signs of detonation most often.
I asked this question once before and the answer was, there was no single cylinder.
Is this really what engine rebuilders are finding?

thanks

 

I am confused by your point. It's the exact same thing that I said. I doubt if he is going to take his mods off so why would he go back to what failed?

 

damn.... sorry this happened to you, good luck on your new motor

 

Boy I know how it is. David will take care of you

Living my Worst nightmare. I could NEVER afford to fix that.

 

Ha, another thing I find amusing -

On the WARRANTY page for the Evolution, there is a link for "Ralliart, high performance parts".

hilarious

 

sidenote: my fuel pump came in yesterday

 

Threaten a lawsuit. State that you have complete and undenyable evidence that the rods let go because of poor tolerances and that the Moss Ferguson yada yada yada is going to leave the burden of proof up to Mitsubishi. Say you have expert whitnesses and engien builders who will testify that the engine let go becuase of poor build quality. Try to settle out of court for a couple of grand in tern you will sign a paper stating that they were not at fault. I did and collected cash, build a race motor.

 

Why not look into an AMS short block.

The only problem would be the good core part.
