CloudSeed777 Posted May 20, 2015 Share Posted May 20, 2015 After watching this, engine r&r isn't nearly as challenging as I imagined. Thanks for posting that. I'm attempting myself to discover whether I should go this route before my current block checks out. I'm at 182k and I like to be proactive. Not to mention I have a whole summer available to do so since I'm an educator. I'm balancing the cost with recoup on selling my existing SB and perhaps selling the existing internals from a new block and going forged on a 257. Sorry to highjack, I'm growing more interested... I did my own short-block rebuild, and it wasn't that bad at all. This guy does make it look easy as he has probably done 100's of them, but I found the hardest part was definitely the wrist-pins. Between Subaru Mike's video above and this guys videos below, really helped a lot. I had the laptop in the garage following along and referencing as I went. https://www.youtube.com/playlist?list=PLaRuYYPxjXI3O4qo86qj-xT_HEzwYLKwB Link to comment Share on other sites More sharing options...
CloudSeed777 Posted May 20, 2015 Share Posted May 20, 2015 P.S. No hammer needed. Link to comment Share on other sites More sharing options...
1-3-2-4 Posted May 20, 2015 Author Share Posted May 20, 2015 I needed a hammer to take my wrist pins out of a ej25d that had almost 300k on it.. that combined with trying to drive a car with a spun bearing.. extra heat did not help. Link to comment Share on other sites More sharing options...
1-3-2-4 Posted May 20, 2015 Author Share Posted May 20, 2015 That was with whateve the hell that turbo came with the car then I got it.. ended up down grading to a VF40 to put less stress Link to comment Share on other sites More sharing options...
gto7419 Posted May 21, 2015 Share Posted May 21, 2015 And if I'm using a new crank and all new bearings I really don't have to worry about the clearance if you torque to spec. What I need to know is that master gasket set does it include those 3 gaskets between the case half of the block? You absolutely have to worry about clearances! You need a dial bore gauge for the block and a micrometer for the crank. You need to check manual for clearances. Link to comment Share on other sites More sharing options...

gto7419 Posted May 21, 2015 Share Posted May 21, 2015 You can't just swap turbos without retuning..... FYI, you were over boosting because the tune was off. Link to comment Share on other sites More sharing options...

FYI, you were over boosting because the tune was off.the tune was off for him it was stock as far as I know What turbo came with the car?not sure on the size I still have the old turbo in my room. You absolutely have to worry about clearances! You need a dial bore gauge for the block and a micrometer for the crank. You need to check manual for clearances. I already own a micrometer but not a dial bore gauge.. So in that guys video why did anyone point out he did no measuring? Was it because a new crank?

Bbc84 Posted May 21, 2015 Share Posted May 21, 2015 A already built OEM shortblock? that's at least $1800... Hell just the EJ257 case halfs empty are going for like $1400 on ebay.. At this point rebuilding is looking like the better option.. I will know more when I call my guy up tomorrow. If you can wait, you should try signing up on email mailing list of Subaru Parts Warehouse. Usually during holidays they have 25% off coupon. I bought empty case halves for my upgraded motor build for just over $800 shipped on black friday weekend ($759 for case, $50 for shipping). Maybe they will have memorial day sale...

New crank makes no difference - still need to measure clearances! I didnt watch the video and I dont care what anyone else does. I check clearances and if you dont want to *chance* your motor, you will too. Link to comment Share on other sites More sharing options...

CloudSeed777 Posted May 22, 2015 Share Posted May 22, 2015 You absolutely have to worry about clearances! You need a dial bore gauge for the block and a micrometer for the crank. You need to check manual for clearances. A bore-dial gauge would be useless to you unless you plan on boring/honing your own block. The machine shop you use will bore and final-hone for your pistons - that's what you're paying them for. As for the micrometer for the crank, a new Subaru crank should be within spec from the factory as they don't ship them out of spec. If you're worried about the crank being out of spec from Subaru, you can always take the crank to to the machine shop with your pistons and have them check it for you.

gto7419 Posted May 22, 2015 Share Posted May 22, 2015 A dial bore gauge should be used to check spacing inside each main. Subtract crank journal measurement for clearance. Link to comment Share on other sites More sharing options...
Max Capacity Posted May 22, 2015 Share Posted May 22, 2015 While your at the machine shop ask them how much to assemble your SB, correctly the first time. I think I told you who I recommend. It may be a hour drive but at least you'll know its done right. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

gto7419 Posted May 22, 2015 Share Posted May 22, 2015 Very easy to screw up - all it takes is something to be out of spec - which happens all the time... Link to comment Share on other sites More sharing options...
1-3-2-4 Posted May 22, 2015 Author Share Posted May 22, 2015 I'm sure it does but I think you are putting too much thought into it.. If I was reusing the crank yes but I wont be. And if Subaru can't be consistent with each crank they need to go back to how to build a engine Link to comment Share on other sites More sharing options...
Max Capacity Posted May 22, 2015 Share Posted May 22, 2015 Isn't that part of the letters stamped into the top of the block Mine is an AAAA block. I know other companies put letter codes on the block for the different sizes. They are not all the same. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Max Capacity Posted May 22, 2015 Share Posted May 22, 2015 FWIW, I have great piece of mind knowing my long block was assembled by someone who knows what they are doing. I think you know how much I drive mine and when and where the car takes me. It was cheap money to pay the man for his time on the long run. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

1-3-2-4 Posted May 22, 2015 Author Share Posted May 22, 2015 When I get back from Florida I'm going to take the engine out and disassemble it. It's no worse then doing the heads and taking the cams out, I pay $150 for a storage unit with all my car tools I might as well make use of them..
