I cant believe it! Fully built, $7500, 700 miles, and CRANKWALK!!

[GSX4LIFE]

This cant be happening. I have had my car back from Extreme Motorsports for about a week and a couple days, when on Thursday I notice a clicking noise when I depress the clutch. Right away I start worrying. Friday I call Extreme. Sean is on Vacation until Tuesday. He is the only one that worked on my car from start to finish. So last night I go into the Archives and read all the symptoms. Well hard left turn, clutch pedal sticks to the floor, GOT IT! Loud ticking noise with clutch depressed, GOT IT! RPMs drop with clutch depressed, and occaasional stall, GOT IT! I cant believe this. Only 700miles. Did the breakin perfect. only been running 13psi on the L2R, already changed the oil at 500miles. Ive had the ar back for only 9 or 10 days. WTF is this crap! Imgona call Extreme on Tuesday. Hopefully they will do the honorable thing. But I have no idea how to prevent it in the future. I mean cmon, $7500. For one week and 700 miles of normal driving? Is this horse crap or what. Mitsubishi is a ### for what they have done to us. Looks like I may be saving up for a 6 bolt swap.

Im sorry to hear that man i hope everything works out for you.

 

[dukmahsik]

man im sorry to hear that... time for 6 bolt bottom???

GSX4LIFE: You spent 7500 on a motor rebuild from Extreme? That’s insane. Its funny a friend of mine went to the same machine shop that they use and had a 6bolt motor of his crank walked as soon as he fired it up and that was on a high priced motor too. That really sucks that this happened to you. I'm sure they will do the right thing. Keep us posted.

 

[brokeawd]

That sucks, I feel for you. Hope everything works out, wonder if the same machine shop is building the bottom ends before they go back to extreme?

 

[HighPsi91]

Spending big money does not ever make you immune from problems.

 

[L2RTSiAWD]

That is why you never build-up a 7-bolt

 

[swordfish]

I have to say this. If you build a 7 bolt correctly it will not take a walk on you. especially if you use a clutch with a lighter pressure plate and better disk. Instead of going the ACT route and using a heavy ass pressure plate and sh1tbox disk. My car is a prime example. And I am going to let one of my little secrets out about the car. Titanium Nitride + Your Crankshaft = some really tough sh!t Thats just one.

The previous owner of my car had 4 cases of crankwalk. Dealership replaced block and crank twice under his owner shop. I am using the same crank that he had during the last 2 episodes of crankwalk. The car has made ~370whp all spring and summer long on the BR20G. I am just as confident that it will hold up under the L3R as well.

OK I am prepared for you guys to flame me about wasting money on a 7bolt.

you spent $7500 to have an engine built!? man, that's insane. you could buy another car for that much $$. what the hell did you have done?

anyway, if you were gonna spend that much you should have at least just built-up a 6-bolt to begin with.

 

[GSX4LIFE]

Well that was for everything, including install and some other little things. I never even thaught about going to a 6bolt, and Sean never recommended it. He was confident so I was too. I hope they make good on this.

 

[RamenPride]

Did they give you any kind of warranty on the parts and/or labor? Just curious.

 

[CL MaNTis GST]

So you never hard problems... u spend $7500 to get an engine built from the shop then bam! ... crankwalk?

something went wrong!

 

[Hobbes =^.^=]

Sorry to hear. I know the feeling. Bought my car, and two weeks later. Crankwalk

Hope everything turns out all good.

=^.^=

 

[larryd]

WOW.. thats about the only word thats escaping from my mouth right now.. I was going to rebuild my 7 bolt block when i spun a rod bearing and finally the better half of me kicked me and said 6 BOLT..

I wish you the best of luck man.. I know how it feels to be where you are right now.. Outta curiousity what did you get for 7500??

 

[dyezak]

7500 isn't bad for a top end shop to build you a motor and install it...hell, most charge around 5-6000 depending on the install (6bolt in a 2g is more expensive). You guys have to take into consideration $75/hr labor rate, shop supplies, initial tuning time among other things. And god forbid you have any problems. I have redone some big name stuff before because of oil leaks and most recently a stage III Buschur 6bolt crankwalked on a guy after 34 miles. Rule number one...NO DSM motor is immune from crankwalk. Rule number two...want quality work and the warantee to go along, you are going to pay. Extreme will take care of you, don't worry. But if they don't, call me (just IM me or e-mail me, I work at another shop).

 

[GPTourer]

I just saw somewhere while reading a tuner magazine that there is company making crate motors (short blocks at least) for Hondas. Wouldn't it be great if the top names in DSM motors collaborate and find us a real drop in solution by creating a bulletproof bottom end that we could all just drop in?

 

[95gstproject]

i think it is dart that build blocks for honda's of course maybe later they will for our cars too.

Aren't the mains on all 4G63s tuftrided stock?

 

[Trippnup2]

That sucks ass bro! I wish you the best of luck. If my car crankwalked after 7500! I would SHOOT the mother. Hopefully extreme will come through for you! If not I hope you paid with credit. That way you can dispute the charge! Visa/MC is the #@%#@%#@%#@%! Good luck.. Let us know what happens!

I couldn't agree with this more.

 

[StockSpyder]

Damn man.. Im sorry to hear that.. I hope Sean does the right thing. Keep us posted.

 

[rick]

one thought. how could mitsubishi live with themselves after building such a crappy motor? if it walks, then obviously there is somehitng wrong with it, right? i mean, i see all this and cant help but think there has got to be someway to stick it to mitsu. jeez man, i could understand an o-ring or gasket, but crankwalk? that is serious, what where they thinking?

 

[GSX4LIFE]

Thanks guys for all the support. We will see what happens on Tuesday, when I talk to Sean. I really am comfident he will stand by his work.

 

[Violater101]

I'm tired of hearing that it's all 7 bolt's that just walk. I would never build a 7 bolt blah blah. 6 Bolts walk too, they just don't have sensor that 7 bolts do which often tell the tale alot better.

I'm sorry to hear about your problems and I hope Extreme does the right thing, I'm sure they will and I don't think that is a bad price if sean himself did the work on the car. Install's aren't cheap, especially when you are building the motor up from the bone.

No CAS on 6-bolt or 7-bolt 1G motors
