That's cool. They only have to run for 90-12" seconds at a time and most of they time they actually run that long they start having problems. Oh, and they probably bring spares.

That kinda bull**** does not belong in a legitimate vehicle.

 

I am guessing this 5 year or 60k is for 4G63 engines. Anyone knows what EVO X intervals are for those chains?

 

Was getting close to both limits. Car is a little over 118k miles and its been close to five years since ER did my last timing belt job. The belt snapped almost clean across.

That piston is definitely not in good shape. The only moving forward I would be doing at a minimum would be replacing all four rods and pistons. The cylinder walls look ok but I'd definitely get them inspected before doing drop ins. I'm leaning more towards just doing the 2.4 LR build I've been planning for a while since this **** is already apart. Only issue now is money.

 

I'm pretty sure the chains don't need changing unless they stretch. I think there was issues with the first couple of model year X chains that made them prone to stretching but the chain was revised in like 2010 or 2011 (can't remember).

 

Yup, there was a recall back than when they replaced some of that stuff. Still, I am not sure if there is a set interval for those on when they need to be changed/checked at least...

 

There is not a replacement interval for the chain in the 4b11 that I'm aware of. It's not in the service schedule in All Data, but the timing belt for the 4g63 is.

 

Thank you!!

 

At 120k, I wouldnt do a new pistons/rings without at least a full teardown and honing the cylinders are a machine shop.

Your head looks salvageable if you send it somewhere that knows what they're doing to repair it. I'd suggest head games.

If you just did a rod/piston build and labor yourself, you'll prob be in it less than $6k. Another grand if you get a 4g64 block and the other needed parts to go with it.

 

Looks like I'll be going the 4G64 route. Price is about what I figured. I got a good hookup so I'll be able to cut that price down a bit hopefully. Will likely be doing the swap in my garage.

 

Got my diffs back. Now I can get back to assembly to put some miles on the new R&P, clutch LSD discs, and exedy twin before ripping in april. 500-1000 miles will be tough, I usually only put about 1000mi on the car in a full year which is all on track.

 

question on boost in cold weather - i've got a tune on the golf r that is supposed to see 22psi, which only sees 17psi - people on the golf forum say you will see less boost when it's cold outside - i've never heard of that before, is that true?

 

I would ask the tuner. I'm not familiar with how that car does boost/Baro/temp compensation.

 

If they measure amount of air that gets in, running the car at cooler temps would get you the same number at lower pressure.

 

Yeah, VW's are MAF based with a complex ECU I could totally see the ECU making boost comps for this stuff.

Maybe @razorlab knows?

Edited to actually tag razor because apparently none of the new VBulletin functions work on the garage talk app.

 

makes sense.

going back to the evo, i still haven't gotten to further diagnosing the noise, but I am pressing forward with pre-crash plans, including swapping in a superpro steering precision bushing - i think the WL one is junk. While we're going to have the subframe down, I think im going to go BACK to the stock front sway bar - I haven't been crazy about the handling on the evo since the FSB, even with a larger RSB the front end never felt as responsive. The FSB was a result of all the talk about how for mcstrut, it can help maintain camber, and while that might be true I don't know if there's a ton of actual benefit there. thoughts?
