So i got the cob stage 2 last week and installed it. car spools great but at around 5k -5500 the car would start to sputter and then the fuel would cut. i have a mbc so i turned it down a little with the same results. i did research on the ap forum and found that alot of people were experiencing this and i need to call cobb. Well i got the idea to do a compression test just to see if everything was A OK. Well... its not. i followed the manual instructions to the "T" and here are my results:

#1 155
#2 130 135 w/ alittle oil
#3 165
#4 165

Yes you are seeing that correctly. I have ring issues with #2. This is not good (obviuiosly) anyone have an idea how much and how long to get this fixed by the mitsu dealer. There is no one around my immediate area as far as shops go.

 

I wouldnt go to a dealership to fix it, you could get aftermarket parts for a lot cheaper than what a dealer would charge.

 

To be honest I wouldn't have mitsu. fix it. Also you may just want to be easy on the car for a while and save up and just build the motor, especially if your going to mod it anyways.

 

perfect opportunity to do a bushcur racing built 2.0

 

i would put it back to stock and see if you can get a new motor under warranty

 

yeah only prob is i think the warranty is up. who do you call to check?

 

ha ha i don;t think i want to know what that runs

 

yea build it, make it better.

 

Interesting.

 

Has anyone actually had a complete motor replacement under warranty? Seems like quite a stretch.

 

I had my Rod and Crank Bearings replaced, along with new Rod Bolts and a little polishing to the crank. This was at 18K and completely stock, with records of oil changes every 3K. James Reese was the service tech. at El Cajon Mitsubishi at the time, and worked with the Rep. on the 100% covered warrenty.

 

is that James Reese in cali? I've done some tuning work for his shop cars...just wondering

 

Same guy Chris. This was last year when he was employed by El Cajon Mit., before that RNR...The guy gets around.

 

You sure its the rings?

It could be just as well the valves not seating properly you'd have to pop off the head anyways to get the engine built so why not have it pressure tested.

 

true. where would be a good place to do that? what the dealership be good. I am very disappointed right now and can't think straight. I mean i only got the thing in december. Starting to wish I hadn't
