We are an authorized Dinan dealer here at Mckenna BMW however I won't be putting any tunes back on this car. I'm kind of paranoid now that something is going to go wrong plus I'm all out of funds at the moment as I opened up a Detailing/Vinyl wrapping shop last week.

Why are you parting the car out?

Not parting it out just yet but I will be selling her shortly after I get her back from the shop.

I will more than likely be joining the dark side and getting into a W204 C63AMG sedan

CalCarNut · 07-21-2015, 07:31 PM

LOL...seriously? Pretty wicked car. Just watched a video of one killing a HellCat..

e46m3lol · 07-23-2015, 02:34 PM

The suspense is killing me!! I'm crossing my fingers that I get her back tomorrow evening

e46m3lol · 07-25-2015, 06:51 PM

Didn't get the car back yesterday. Found out the engine is put back together but still has to be dropped back into the car

CalCarNut · 07-27-2015, 11:39 AM

So close!

Not sure what you mean by that...

Obviously didn't read the entire thread.......

Do you think a ECU tune like the GSR one on the other thread would've avoided overboosting the piston? or past a certain limit it probably won't matter?

I would say overworking the engine and pushing it to its limits no matter what tune the car is equipped with is going to lead to premature engine wear and in some case (like mine) damage the engine. So far from what we know is that the rods and pistons seem to be the weak points in the n20 engine.

SteveInfante · 07-28-2015, 06:11 PM

So far I think you are the first person to blow your N20 up and figure out where the weak points are based off of that.

I'm not the first person to blow the N20. I know of 2 other locals besides me with blown engines. One of them had a hole through the side of the block due to a damaged connecting rod.

SteveInfante · 07-28-2015, 06:50 PM

Ouch. Well, the more people that blow up these motors the more we will know about where to build them to be more reliable in the upper HP ranges.

True true... I went with OEM internals as I don't plan on keeping the car for too much longer. I do believe GSR Autosport is building theirs with forged internals if I'm not mistaken.

SteveInfante · 07-29-2015, 04:52 AM

That would be a good idea I would think. The new C63 is a beast. I'm sure you will enjoy it thoroughly.

e46m3lol · 07-29-2015, 09:00 AM

Mechanic sent me pics last night and the engine has been put together and it's back in the car. He still has to turn the car on and make sure everything is good. Looks like I might be getting her back today

I'm not a fan of the new C63, they're a little too bulky for my taste. I would be getting something like a 2011 C63 sedan.
