offroadsubaruguy Posted July 1, 2005 Share Posted July 1, 2005 well, $100, and a case of beer later i have a 2.5 bottom end...... it only had a slight tick, but they replaced it anyway, so im going to rebuild it.... first off, a few q's. are the oil pans from the 2.2 and the 2.5 the same? any one have any idea as to how much rings and pistons are gonna cost? has anyone ever balanced a motor before? how much did it cost? and if there's anything else i should know, clue me in......thanks Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted July 2, 2005 Share Posted July 2, 2005 I would think the pans are similar Don't know the costs for the 2.5 specifically, but the ej22t motor, rings cost around $118. Pistons run about $55 a piece. If you decide to split the block, which you probably don't need to, you should replace the bearings. You said the engine had only a slight tick? Any idea what was causing the tick? It might be a good idea to check the bearings if oil starvation might have been an issue. Quote Link to comment Share on other sites More sharing options...
reddevil Posted July 2, 2005 Share Posted July 2, 2005 Contact these guys. http://www.discountimportparts.com/ I paid $117 for the headgasket set, $66 for the rings, and $107 for the pistons. I have a basic rebuild, timing belt, clutch DVD available for $7.50. pm if interested Quote Link to comment Share on other sites More sharing options...
ShawnW Posted July 2, 2005 Share Posted July 2, 2005 Pans are interchangable. Theres a 4.2 qt and a 4.8 qt one. The flat bottomed one is the larger with the round bottom being 4.2. The pistons are usually fine. Scoring on the side indicates prior piston slap issues and tollerance should be measured when this shows. These are balanced from the factory. Turn the crank and have the heads surfaced by a machine shop and you should be good to rebuild. Quote Link to comment Share on other sites More sharing options...
ballitch Posted July 2, 2005 Share Posted July 2, 2005 i agree with the above, import motors now-a-days are pretty well balanced and all that jazz, now if you wanted to spin at a higher rpm, you might think about balancing the rotating assembly and blueprinting the motor for tolerances, but whoa wants to spend that kinda dough on a motor that will last 200k with new rings and bearings? ~Josh~ Quote Link to comment Share on other sites More sharing options...
jib Posted July 8, 2005 Share Posted July 8, 2005 I don't know about Subie parts, but a good balance, from a reputable shop will run about $150-$250 for +/- one gram, depending on where you live. I guessing that you won't need to balance it though. Most modern cars are pretty darn good. FYI - my 1960 Triumph's crank was almost perfectly spot on for balance. The rods and new pistons, however. . . . BTW - I'd consider sending these guys http://www.totalseal.com/ your second compression ring for their gapless modification. Relatively inexpensive and a great product. I'm so impressed with the results, I'd have my lawn mower's ring converted if I rebuilt the engine.
