Sounds like doing surgery while holding the scalpel with your buttcheeks though.
That's why I'm waiting for someone else to be the guinea pig.

Maybe someone can try this on a motor that's already out of the car, just to see if it's physically possible.

I've thought about that many times. Oem pistons and bearings are great- it's just the rods. And as observed the offset cap...

Thing to do would be to do it on a factory new block. Trouble would be matching the bearings/conrods the crank

Hey that was my post. I wouldn't dare try it motor in. Seems like a horrible way to rid your knuckles of skin. I also said it wouldn't be easy. Like running a marathon in flip flops. It makes no sense, but eventually some ******* will do it.

"The rod caps are split at an angle, much like the OEM components, so you can torque the hardware and install rods while the block halves are together. "

Yeah that is a problem. You'd have to spin it to BDC and carefully measure it with the right mic through the sump.

These darn rods....the only reason I quit modding and then started itching for a platform with more potential, though the car fullfills all my needs wonderfully......

Hehehe same here. It is an untouchable package at this price level. There is so much aftermarket support it is insane and parts are so cheap too. First car I ever owned that I haven't got bored with after 2 years.

They are far from cheap. With the money I put into mods + the cost of the car, I could've bought an STI. Not saying I should've (though I do like the STI drive train and brakes), but parts aren't cheap.

IDK. You can by a new GTI for under 24k, and with an Accessport and our free tune, you can make 300+whp and 370+wtq on completely stock hardware, and no rods will ever been thrown out the side

Stock GTI with a $650 AP and MAP Stage 1 tune:

No but your car will start misfiring and cutting out randomly for no reason then VW will tell you its "within normal range" and to go take a hike.

Then 2 years later they will silently revise a coil pack and with the combination of Audi RS7 plugs will fix the violent spark issues some of the cars come with from the factory.

Ask me how I know, took apart and put a launch 2015 GTI back together 3 times last summer, I absolutely hated that car by the time I sold it.

Oh and don't forget, if you do blow an engine in a VW its minimum 20k for a fix.

/end rant.

Hehe I see what you did there but that is a lot of power going to the front wheels with a car that has well documented clutch and turbo failures. Eventually you will need to start spending money on other components to keep this reliable. They have a very sophisticated ECU but even that get only do so much.

Having that said, that is not a knock on the car or you guys. Keep up the great work. Your tunes are amazing and I will be picking one up for my WRX very soon. I will also recommend your products to my VW crew friends.

I am being 100 percent serious here, I had a 2.0 TSI DSG MK5 Jetta and for the amount of money that car cost me just to run, it would have been cheaper to rebuilt the FA20DIT after a rod failure...

VW's I've owned/currently own

2009 MK5.5 DSG GTI w/K04 FBO tuned by Driver Motorsport - Lost all DSG gears multiple times due to a bad DSG tune by Unitronic. Sold.

2015 MK7 GTI 6MT - FBO with BMS JB1, can ran great for 1 year then started having massive issues caused by bad spark, VWoA denied any issue and would no longer service the car until a CEL was set. Car was stock at the time of all services. I could log 30+ misfires at idle in a cylinder and moving coil packs and plugs around did nothing, apparently its normal and part of the idle process according to VWoA. Sold for the WRX.

2005 VW BEW TDI 5MT - Daily Driver, that car rules it has its issues from being old, but still reliable.

Currently I have a 2017 WRX that is COBB Stage 1 and on AirLift. I find myself saying "why is this so easy" every time I work on this car.

No ragrets, not one letter.

I'm not sure where to post this but I can't start a new thread as I just joined this forum to make this post. Sorry if this is not the right place for it, but I think it may be important to document this.

My 2015 WRX is completely stock. The only thing I've done to it is put winter tires on it for snow. I bought it new in March 2015 and for the most part have loved it.

As of this posting it has about 31,XXX miles on it.

The warranty will be up (from what I know) at 36,000.

I'm about to bring it in to my dealer for the third time for a fluctuating idle (often bottoms out on the tach) that seems to get worse until a CEL comes on. There are multiple posts on the internet for this issue, but I haven't seen anything that sounds concrete as far as a solution. Many of the posts seem to be people who are experiencing a little fluctuation and vibration that accompanies the horizontally opposed engine.

This is not that.

All service was done at dealer as per suggested intervals.

The problem first became noticeable in May or June of 2016. The error code was a camshaft slow response (I forget the code number). A cam sensor was replaced.

The car seemed fine for a long time after that.

Over winter and into spring the same problem has come back. Same thing, it got progressively worse like it was going to stall out and eventually the CEL came on. This time, by the time I got it to the dealer, the CEL was off. They were able to get a different code than the first time even though when I ran the code I got the same code as the first time. They replaced the fuel sender.

That was a month ago.

The fix did not help much and again, the idle is getting rough, fluctuating, and eventually the CEL popped on again yesterday.

I am beyond frustrated.

I'll try and get all the paperwork I can together in the next couple weeks and try to give more information.

If anyone has anything similar in terms of experience or know of any other people documenting this I'd appreciate it. I couldn't find much...

I read as much of this thread as I could. Seems like some real knowledge on here. Thanks for taking the time to read this.

There has been a ton of fa20 that have had p000a and p000c codes from bad oil control solenoids, or whatever it's called. Check out the link I posted of a thread from this forum. Hope you find it helpful

Did you get the recall done? My 16 did the random low idle thing once in a while, but after the recall its been golden.

Dipped on WOT on the freeway (I road raged and downshifted to 3rd, admittedly; engine bucked and I lifted 100% immediately) to DAM .375 and feedback knock to -11.98 the week after my 4th or 5th track day. If it blows, I'll share more info here, but DAM went back to 1 and all is well again.

Background: 2 gallons E85 to 13.9 gallons ACN91, protuned to 249 HP (Stage 1 mods like EBCS, intake, TGV delete, EGR blockoff, IAG AOS competition) and only fills up at certain gas stations (I haven't been on NASIOC for a while, even to upload all my oil analysis results using Motul 5W40, but all has been fine in that area).

Default 15+ WRX Motor failure roll call!

Sounds like quite a scare! The feedback knock in the AP screenshot only shows -1.41 though? Maybe the screenshot isn't of the run that went bad, since boost was under 12psi and DAM only went up to 0.625.

Probably worthwhile to check for the obvious loose fittings that could cause knock when you're at WOT and the driveline is under the most load.

Otherwise, maybe get back to your tuner and send him some logs for review.
