+ once one of the mains gets beat down and you start to get more radial movement of the crank then all other bearings suffer including the thrust bearing.

...and maybe a bent rod

so is the crank walk a result of the bent rod....or is the bent rod a result of the crank walk?

is there any way you can even tell?

More likely the bent rod side loaded the thrust bearing and wore it out.

i agree with 360...bent rod from high cylinder pressures, along with detenation, simply crushed the thrust bearing. the more i drove it the more it wore away at the bearing giving room for more play. as the crank moves horizonatlly, the angle of the rod is changed. this wears down the rod bearing.

knock = not good. avoid it if possible. lol.

pm me a deal 360, maybe this time we can work something out...

Up because Junior's thread was for me to drool over stock 2.5's and think about what that car would do with another grand of redline and cams.

Do I beams and make your 135 happen!

thanks zee....appropriately placed.

i slept on it and first thought this morning is the I beam is gonna be a bit overkill for the rating. then i thought about the material of the rods being different.

to do it with I beams keeps me out of competition at etown.

you guys arent feeling the h beams huh? even though they are rated to 800hp?
the sti rod, the h beam and the I beam are all forged, but different alloys? different stretch limits?


the sadness is sinking in.

Without drawing this out, ask yourself:

Q:What do you want to do now?
A: 10.80@135!

Q: What do you want to do later?
A: 'insert username here'

Talking about how you figure Junior's car was within reach in a bit, I'm guessing that'll be a hope for your personal setup. With the company you keep, and because none of us are satisfied until we're scared, build it right. The first time.

H's will be going into the motor I build, eventually. Not only will they bend rather than fail, I don't have mounds of money and think headwork is more important. Gotta pinch someplace if I plan on pulling elsewhere. With that said, my power goals are lower (30r is about my ceiling).

Famous last words...

Jake,

Do a simple exersize....How much does it cost just to pop the heads off? Gaskets? Bolts? Time? Inconvenience?

Now compare that to the extra $400 up front....

Which is the best way to go?

aircraft quality 4340, vacuum degassed, shot peened, magnafluxed.....how can you go wrong with so many big words like that.

Jake when I pull my long block, you wanna throw it in your bug and see how long it last with that 30r? I would bet money it goes another 30k without a hiccup

The ONLY REASON I am pulling my motor out before the race is because I want to run so serious ET/MPH with the XT and drive it home. Plus I dont want to ruin a perfectly good motor by hitting it with 35psi on a big turbo. Im sure it would survive a few passes like that, but it would be short lived.

All this stock motor talk reminded me of porkchopvic and his 04 sti.. We were making 550-600whp on the stock motor (cp drop in ) and street racing, track racing, high speed pulls for 30+k miles and never once broke a thing in the motor. We could walk 130mph supras from a roll as an indicator of what it made for power. @ 420whp we went 11.3-4@122-124mph..

everyone has a story like that.....

but if someone calls you and asks what rods to run on a gtx30/35 setup your answer isnt going to be stock.......or is it?

sounds about right. my car went 11.4 @ 124 at an estimated 420-430 airboy.

but the brakes just got put on.

karl took his heads to d & f the same day i dropt my junk off. he wants to have them looked over so he can sell them as bolt on upgraded 2.0 heads. so dave calls him this morning with bad news. apparently FONSE PERFORMANCE charged karl to lap in the oversized valves when he paid for +1 valvejob. the "valvejob" fonse performed didnt even seal most of the valves. take one step back. karl paid for said valve job and recived the heads with moonlight through the back side of the valves. this is after spending the money and time to install and assemble the motor. of course it barely starts with very very low compression. we take it apart and see the shotty work. after they "repair" their botched work, hes still left holding the bill for the money wasted on the original install.
now to the current situation. car makes power and goes fast but has a very short life.
we take the heads off and notice some serious carbon build up. karl fills the backside of the valves with fuel and sure enough in the closed position they leak. if the engine had not failed so shortly. he would have surely burnt a valve eventually. fortunately my car is apart at the same time and my ambition towards looking for a new local machine shop has set us up with a couple of gentleman karl and i both feel comfortable with.

so of course now i have to call and get mine checked. my heads are already at d & f to address my new cam damage since the repair fonse did on my cam gear oil galley/journal didnt seem to be very good. basically scarred my new cam...

dave didnt realize my combustion chamber work, and valve job were also performed by fonse.

so i get bad news as well. it seems as though no valve job was done. they simply robbed us and lapped in larger valves without opening up the seat. which ends up being more harmful than helpful. big valve in a small hole...

we are going to address fonse performance tomorrow. i no longer recommend them for numerous reasons.

so looking forward we will both have to pay someone else to do the valve jobs correctly.

i have also decided to just wait out turbo tuffs.

maybe it comes together for the shootout, but its not looking good for me to be racing that day. the wife told me this morning if i skimp out and it blows up cause im being impatient, shes cutting my subaru allowance.

Wow, so unfortunate.

As a fellow business owner I just don't understand how these owners of shops/engine builders can sleep at night while robbing people during the day.



Just goes to show a built motor or redone motor doesn't mean anything unless it comes from a trusted source.

I feel these types of stories not only plague the Subaru community but other import communities as well.

Best of luck broski, yah just wait. I want to save up and do it right, until then, there is no point to play. I just feel the I beam has a better knock eating potential...please use e85 if available, it's awesome for safety too.

i want to use e85. i am fortunate to live 10 miles from one of 2 pumps in all of new jersey.

i have recently been informed that my walbro and my rubber fuel lines will be broken down by e85. i def dont have an extra grand for AN fittings and lines right now, not to mention a proper pump. i can only imagine what e85 eaten rubber goop does to my injectors,and fuel filter.

is this false? rubber fuel lines ment for gasoline can't handle e85?

^^ personally i believe that to be a bit of misinformation.....as some pumps already have e20....so from my point of view the fueling components on any OEM car should be ethanol compliant since its already present in regular pump gas.

Like i told some else....if you want to check for yourself get a gallon of e85 and stick a walbro and some rubber lines in there for a month and take them out and inspect them. The best subie example i can think of off the top of my head is juan. he's been running stock fuel lines and a walbro for years on e85

thats promising ron...karl has a full tank of e85 he will be dumping so i'll just syphon a bit out of his car and get some rubber and an extra walbro in a bucket.

trouble about the bad news about fonse's less than good service is that alot of us in the area got work done there this year...

my wife wants to take him to court for charging us for something they didnt do. michelle is wearing her angry eyes.

you could also ask juan to take his apart and take pics while his car is down to see if he has any noticeable effects from e85

post some pics and materials involved, juan!!!

My engine is ready to be pulled I just been too lazy and enjoying my honda getting 50mpg .

Seriously, it should be apart for sure next week, I will take pics if I find something unusual with running E85 for 30k miles. People are going to hate me for this but my rebuilt is going to be replacing the valves that are burnt and whatever that needs to be replaced, taking out the pistons, doing a hone and reinstall them with new rings. Also I plan on using ARP head studs this time . I hope it last haha.
