Default Prevents Build, wont change the name again. I promise.

With work cutting hours and being a college student.. Sometimes things don't get done as fast as you hoped.

The parts...

2007 EJ257
Eagle H-Rods
CP 99.75mm 9:1 CR coated skirt/dome
ACL Standard Mains, HX Rods
2009 STi crank nitrided
ARP headstuds
09 11mm Oil Pump
Covert Performance Oil Pickup
Every OEM gasket i would ever need....

Just a simple 2.5L rebuild with new and forged parts. Motor will be ran on a VF39 over winter to break it in and to also wait until the summer blend of E85, when it will be switched to a *possible* VF37/20G hybrid twinscroll on E85.

splitting the block



Damage of the spare block... #4 and #2 both had crack ringlands

For having two cracked ringlands, the cylinder walls were perfect... very minimal skirt wear, much less than the other block i had., cross hatching was very apparent. I'd estimate the motor had 15k miles tops.




got the pistons in the mail (Thanks Real Street Performance)



The Rods, was going to go EJ257 0 mile rods, decided $200 extra was worth the security and weight savings!!



The combo



New 09 crank... worth every penny seeing how nice it is..



The parts



I has coated pistons!! yah great work by Lo-Ko here in Chicago.




Block goes to the machine shop sometime this week, whenever i have a day off work.

DO NOT use any Permatex... speaking from a bad experience. I used the Grey stuff & had a motor spin a bearing in 40 minutes, the stuff never cured even after 2 months of sitting & when it came in contact w/ heat & oil, it turned to jello & got sucked up by the oil pick up ..

Got a little problem here.


I want to do a hard break in, but i will be on a brand new clutch....

by hardbreak in i mean, for the first 25-50miles it will see no boost. And the motor will be done with the break in at 350miles or less.

As long as you don't slip the clutch you will not hurt it. All the way off the clutch and tip in

Andy will be doing my tuning, from basemap to break-in and pump. But im kinda thinking about letting Junior tune my car on E85. Both are capable, but Junior just has more "proven" cars in the 11's with E85.

I ran 12.6@ 106mph at the 2009 shootout, for 2011, im shooting for a very low number...

We'll see. Due to availability andy will probably just tune both pump and E85 plus he's been a good friend for several years now.

That Jr guy sucks!!!

What are you doing for PTW? Are you going to gear your ring/ptw clearances more toward the e85 or just an all around pump setup?

Oh and make sure you measure the big ends on your rods vs the crank and then the bearing gap before you throw a full set of HXs in the motor. You might end up with some very loose clearance.

Really Cuz I thought he was fair to mediocre
How much different is the psw clearances for pump to say race gas?(100 -116 oct) & E85? Looser or tighter? & I thought rings gaps was more dependent on boost levels being run ?
Please enlighten me

PTW clearance is at .0030" according to CP, they're also coated from Lo-Ko.

Jr
I told the machinist to call me if the clearances were too lose, it was one of the biggest things i emphasized i told him "Hey most eagles run tight for subarus, so here are some HX's let me know if anything is wrong i can order standard" For his domestic motors they've ran looser. But last i talked to him on wednesday everything appears good.

Is what i was talking about with Eagle's

***ONLY*** the rod end is HX, the crank is STANDARD
