700 miles on the new 257 block and heads.
mahle pistons, acl bearings, arp studs, nitrated crank

this tread is almost scary, after spending +4k in the last two months i was hoping for a little more reliability. unfortuntely i didnt do enough reading before build and had was too high expectations, hopefully this block/rings make it at least 30k, its a little noisy when cold but doesnt consume any oil thus far, my biggest concern being the piston to wall clearance

63k on fully built motor, 330 to the wheels at 5000 ft on conservative map, super quite even when cold.

That sounds awesome. 330 at the elevation is a good amount of power for that duration. Care to share your build?

Financially I cannot deal with the thought of hoping for 40-50k at best before needing another rebuild. It seems a built motor is for the guys wanting a lot of power along with the ability to beat the hell out of the motor without desiring/needing longevity.
This is exactly where I'm at with my stock ej257. It has 92k miles and counting (DD) and I'm getting nervous that it's going to poop a ringland after reading all of the horror stories on here. Burns about a quart every 3k.

And on the 2nd bolded part, I agree too. Thing is, I think I'll move on once my car nears 140-160k miles, that's alot of mileage and I would much rather get a newer wrx/evo/whatever than just keep sinking money into this car. 50k miles is pretty damn good when you consider the power density of running a 4 banger north of 400whp, daily driven especially.

Complete RAW performance 2.5L longblock. CPs, Pauter rods, ACL bearings, Ported heads, Kelford 276s, over sized, valves, ect, ect. On 17psi car made 400whp (kept low boost because the car still had the stock 5speed). Lasted a bit over 5,000 miles when it failed a leakdown test past the valves. No marks on pistons, or valves so were assuming they weren't true when the motor went together.

Also, the crank thrust was enormous. You could push the entire crank back and force enough to hear a *thud*. It ate the ACL bearings up and ruined the crank.

Car never got hot, ran Shell Rotella 15w40 the entire "life" of the motor.

5,000 miles. Five. Thousand. Miles.

Now at roughly 34k daily driven since my last post at 12k. Sometimes a quart or so of oil will disappear every oil change (3k), sometimes it wont burn any... And I still have no desire to see leakdown compression results. Power seems to lack what it used to be or its probable thats all in my head. A built motor has been a good learning experience but until I have enough money to play, Ill be back to a stock block on the next one.

This thread would be twice as useful if those of you who are getting good results would post the names of your builder, installer, and tuner.

everyone needs to have the block honed and ring gap set with thick torque plates simulating distortion like the heads were on, also, most likely with the bearing clearances you will have to buy more then 1 (maybe 3, 1 sized under stock, stock size and 1 size over) set (sized) bearings to achieve everything coming out to the same, mix and match them all to get whatever you are going for (same for all or just about the same/ do your best), for me its going to be .0015 for the mains and .002 for the rods, and .0035 for the p/w , per team screams specs for my set-up

I had my expensive closed deck shortblock go with in less then 10k daily driven miles, due to (supposedly) bad valve job, and/or wrong valve guide seals (wrx on an sti) which this I dont understand because I thought wrx/sti valves were the same

fact is, if you are able to do it yourself or check it yourself, do so, if you would like peace of mind, offer to spend more with the builder to have you there at least to check over the clearances with you there to ensure what your paying for and what your driving, measuring tools can get pricey for nice stuff, im at over 650 and still have a few minor things to go

knowone is going to take the time doing all the work for a customer as they would for their own motor, thats why its all unfair, for the amount of work, I understand why most just whip it out and slap a 3k price tag, I mean 2250 in just parts for h beams and a new case, bearings, crank and pistons, used case subtract like 700,

to do it right, while measuring, everything needs to be torqued down, checked, taken apart, redone swapping the bearings back and forth if need be,( a BUNCH) of times until everything comes out to your desired specs, and until the read-outs are all consistant, I dont think that using these measuring tools is at all cake, it takes some practice to get it down

Car blew ringland on cylinder 3 roughly a month after I posted this . Now has a built motor with 2700 miles, and it's pouring white smoke on startup. Pressure tested cooling system, held pressure fine. Ah, the joys of owning a money pit .

EJ205 built by my subie guy and mostly assembled by me.. Hard Break In! Honed, Rebuilt heads, Stock Internals with ACL main & rods. Running Cobb Stage 3 (93oct) VF39, Sti Pinks on 19lbs catless etc.. she stinks, only a small puff of smoke on extremely hard driving, startin to weep oil from the valve cover gaskets, runs like a bat outta hell at 42k strong! Building an EJ257... all forged this time.. lol. wish me luck.
