sounds like a bearing. honestly not sure what i'm going to do at this point. not parting out...just not sure what i'm gonna do.

edit: my oil may have been low, which is weird cause i checked it two fill ups ago and was a smidge under the top fill line. i'll check it out tomorrow when i have energy.
hope its nothing too serious.

Man I'm so sorry to hear this

I just saw the video and my heart sank after hearing that noise. Didn't mean to jinx anyone just more of a preventative maintenance sorta post.

Hope it's just something in the head and not damage to the shortblock as well.

That’d be a spun bearing... ask me how I know. 🤮

How are you determining spun bearing vs valve issue?

From what I gathered, rod knock/bearing the noise is not consistent and shows up at some RPMs and not others, loudness of tapping fluctuates, etc.

This sounds very consistent, timing wise and noise level, etc. which is more valve/tappet related.

Who knows though right?

I'm not parting out my entire car, but I'm probably going to be parting out my entire FA20DIT(what is left), STI Trans, etc....

My project has come this far, time to take it up another notch and do something crazy...crazy and reliable.

Curious what route you will go? V8?

At this point, yes most likely.

I've already reached out to a local race fabricator with a lot of experience doing V8 swaps into all sorts of cars (Marcus Fry Enterprises in Redwood City, CA) and had a brief convo. with him on the phone.

I sent him some more info in an e-mail just now so I'll wait to hear back and get an estimate. On the phone he mentioned he just gave a quote to another guy who wanted a similar package and it's about $10-11k for the engine (600hp crank) and then all of the extra costs of getting it to fit in the car.

To get past 450ish hp on the FA20DIT it's a huge step up for me. To get it running at this level I'd have to invest in a new short block (closed deck or sleeved), I would have to get the P&L port injection kit, secondary controller, new turbo kit + bigger turbo, etc. etc. This is pushing me way past or equal to the budget of a custom conversion.

I can make 500whp all day and not have to worry about reliability. The car would become RWD, but that's okay with me to be honest. Ironically enough I was already looking at spools to convert the STI trans into RWD because it would be more fun and rewarding to drive.

He's not available to take my car in til the end of January, so I may have to play a bit of a waiting game. It's okay though I need some time to decide what I'm going to do.

In the mean time, gonna go drain my oil and start taking the engine out of my car.

Drop a R35 with a sequencial gearbox!! Sad to hear, cause big turbo was next for me.. not safe for this build seems as though even built blocks are suffering similar fates.. best of luck dude.

I'll never live the flappy paddle life or I would have picked up a GTR from the beginning.

This short block had nearly 30k of hard driving on it, I'm not too shocked this happened. Disappointed yes...shocked no.

This is kind of depressing to hear. One more thing to think about during WOT. Rest assured I'll be following your new build thread closely.

2J swap! I was just telling a friend the other day that it would be cool to be the first person to swap a 2J into the VA chassis...although, an LSx would be pretty epic, as well.

Good luck, sorry about your continued misfortune with the FA.

Sorry to hear man, 30,000km of hard use is at least something.

Was going through the specs on the drift cars at WTAC this year and 90% had V8s and most of them turbo on top of that. For big responsive reliable power you just cant beat it. Just sucks there arent many cars that can turn that have nice V8s in them from the factory.

This pains me to write this but what about a closed deck EJ25 from IAG? Those are proving to be reliable and making good power. Could even get a billet block. You already have the STI trans, then you can keep AWD. To go back to rwd with a V8 questions why keep the chassis and not just start again? Have you done a lot of body/suspension work?

I've put way too much into the car to give it up, I finally had it in a good spot too, bummer. Race car life.

I have a lot of body, interior and suspension work - just check my build thread in the members gallery. I've put in hundreds of hours. I really like the style of the WRX and the utility...as crazy as my car is I can still fit both my kids in the back with their car seats, my wife, and enough trunk space to get away for a weekend. Every single time I get out of my car after rippin around, I have a big smile on my face and I end up staring at it in the garage for a couple more minutes.

I'm not 100% set on the V8, all options are being considered still.

But why V8 and why RWD in a WRX? Cause why not I enjoy modding and enjoy having a unique ride built to my vision. I don't care so much for stock cars, unless I'm picking up a Lambo or McLaren which is not possible for me.
I've spent a lot of money on my car, probably enough to get a Lambo...but getting it is one thing and maintaining it is another.

AWD is great, but I think I'm better at driving RWD cars. AWD is all about momentum and grip. RWD is about power and control. Coming from the sport bike world it's hard to change my style of attacking corners.

It sounds fun on paper, I just have to get some more questions answered before committing down that path.

Sounds like fun on paper and to dream about. Exactly. IMO, you'll be wasting your money and time trying to do this V8 or whatever motor conversion into a WRX. Most any shop can figure out a way to drop in a different motor, but there is SO much more to it, especially in a late model car assuming you want everything to work as factory. To undertake such a thing, you will have to do the following things:

1) Figure out how to get the new motor's ECU to talk to the Subaru ECU and various other onboard computers that manage a host of things like stability control which control the electronic throttle among MANY other engine systems. How will you or your installer address that? Does your installer have a capability to do such modifications? Do they have someone that can crack and modify the coding to make the systems talk to one another? I highly doubt it.

2) Are you willing to put up with a ton more NVH? There's no way the installer will be able to make engine and tranny mounts remotely as daily driver friendly as OEM.

3) Which tranny will they use and how will they be able to make it work with the rather small OEM tranny tunnel, shifter and console opening, etc. etc. etc.? Most RWD trannies have direct linkage either mounted to the tranny itself and internal. Your WRX has a cable shifter. The complexity of making that all work while maintaining acceptable shift position and feel can't be overlooked.

4) Which rear differential will they use and how will they mount it in the existing differential housing/subframe? The OEM diff unit or even a beefed up ring gear and pinion WILL NOT last. It's simply too small and will blow up quickly. The diff currently in your car isn't designed to handle all the engine torque. It's designed to handle maybe 70% of the torque of a stock FA20DIT. There are plenty of strong differential options out there, but they're not easily going to mount up to the subframe due to their much larger size.

5) How are they going to address the rear axles? They are certainly not big enough to the handle the extra power. The axle hubs will also need to be figured out.

A RWD WRX will handle and perform NOTHING like a car that was designed as RWD. Dynamically, a RWD WRX will be a hot mess.

You're much better off cutting your losses and sticking with a slightly built short block 300whp WRX or parting it out, selling the car, and then getting a stock RWD V8 that is faster out of the box than your modded WRX. Something like a new Mustang GT may be that car. Want to go [email protected]+ in the 1/4 mile with four doors, RWD, and a turbo? Get a used BMW 340i, a piggyback tune, and slicks.

I had checked the oil during gas station two fill ups ago and it was 100% full. Which means i nearly burned through 3/4qt in ~450 miles.

My theory is this....my failed head gasket caused from the injector getting stuck open caused more damage than I originally thought. It probably flooded the cylinder enough to ruin the rings/possibly wash out the bearing and it saw too much load. From there it was just a matter of time.

My lesson is when I had the car fixed with the gaskets, I should have just replaced the whole engine at that time. Nearly 30k on a built shortblock with high boost and rabid driving habits, it was probably about that time anyways.

Live & Learn! ... or just live

1. I asked this question to the fabricator myself. All I care for is power steering, air conditioning, and power windows - fairly standard stuff that I don't see being any issue. Everything else can take a hike. I would replace the triple meter display with some custom gauges that give me the information I need (oil temp, boost, etc). Perhaps I need an AIM gauge cluster to replace the OEM speedo - once again not a big deal and easily integrated. If I have to go with standalone aftermarket ECU to handle everything that's an option too. LOL stability control...dude, the first thing I do every single time I get in my car and start it up is hold the traction control button for five seconds. Electronic throttle....you know I would be replacing the engine in the engine swap yes? Fabbing a new pedal assembly if needed is so minuscule in the scale of things here.

2. My car has replaced engine/trans mounts and bushings replaced already now everywhere. I also used sound dampening material all through the car to reduce it. Daily driven as nice as OEM mounts? Man, go look at my build thread I don't think you understand what I already have built. NVH is a non issue.

3. TBD but my guess is a T series trans. The shop I spoke to seemed to have no issues or concerns about making it work...I'm pretty sure all this guy does is put big V8's in cars that were not originally meant for it. Check out his page here and you can see his photo albums of past swaps: https://www.facebook.com/MFR.Fab/ The fabricator told me the size of the transmission and where the shifter ends up is the reason why AWD is lost, otherwise he would love to keep it that way if he could.

4. Probably R200 from a Nissan, dunno TBD - letting the builder decide what will work - still waiting for his estimate, I just e-mailed him yesterday after speaking on the phone.

5. Rear STi axles can handle 500whp just fine, dunno what you are talking about? They would get replaced anyways when changing diffs. Do some more research on your own to avoid asking questions like this.

"A RWD WRX will handle and perform NOTHING like a car that was designed as RWD."
Google reveals info. about people who have done this swap and talk about the handling. Also you can go on Youtube and see for yourself. Not a concern with proper suspension setup. I don't care if my car is not the best handling car in the world, I'm more about the feel and experience these days. I bet I can have a lot more fun in a 500+whp RWD WRX than a 425whp AWD WRX. Actually that's no bet, it would be more, it will be more fun.

No, I'm not better cutting my losses. I think you're confusing your own desires with mine. My current (well, old now?) build already would be trapping more than 115mph. Thanks, but your input isn't needed if you don't have personal experience.

Besides, I stated above "all options are being considered still." I have to talk to the fabricator more and get answers to all the what ifs/tiny things you are starting to mention. I already asked a bunch of these questions in the e-mail I sent to him yesterday. He's booked so far out though I don't expect an immediate response and that's fine.
