Steveman09 Posted August 29, 2006 Share Posted August 29, 2006 Well as many of you allready know, recently I had trouble with my boost controller overboosting me to 30psi during a race with a 2003 Mustang Cobra. (I WON, even before it overboosted) Ended up blowing the passenger side headgasket and toasting Cylinder #1's Piston Rings. The rings didn't supprise me since back when I first built this engine it was run out of oil and Cylinder's 1 and 3 had deep scoring and there was a question as to how long it would last, well I put about 20,000miles on it of hard driving/racing so I guess it lasted a long time given the groves in the cylinders. This time I set off to do it right and I went any got a 89' Turbo Block. I transferred my Crankshaft, Rods, Pistons, Gen3 Heads over to the new block since I had my internals balanced allready. I put brand new Main Bearings and I used NPR Piston Rings this time instead of Subaru Rings as I was told they are better. Honed out all the cylinders to put a nice new cross-hatch pattern in the liners for the new rings and put it all back together. I also finally got the Valve Lifter Clearances right for the Delta 272 Cams!!!! Everything is back to normal now and she is running stronger than before! I have a video comming soon. PICS will be posted tonight I'm at 12psi right now with the TD04, but 15psi will be comming soon! PICS: Quote Link to comment Share on other sites More sharing options...
Jerry DeMoss Posted August 29, 2006 Share Posted August 29, 2006 I am very interested to see some pictures and more info on your engine.I just went for a ride in a sweet rx yesterday(thanks DrKrazy) and I know need to know more because I want one someday. Did you port the heads or have any special valve work done?Thanks Quote Link to comment Share on other sites More sharing options...

matts87glsedan Posted August 29, 2006 Share Posted August 29, 2006 hah that rules. my 87 sedan is even the same color as yours. but non turbo... Quote Link to comment Share on other sites More sharing options...
bgd73 Posted August 30, 2006 Share Posted August 30, 2006 Very nice setup. Is your races at a drag strip, I would love some numbers. Also your #1 breaking satisfies a hunch about what goes where, when it really comes down to it. There's always a weak spot. I like the pics, never had an ea82 apart. Is that middle main bearing all one piece wrapping around like that? Quote Link to comment Share on other sites More sharing options...

bgd73 Posted August 30, 2006 Share Posted August 30, 2006 That's intereresting. My engine ubolted the crank belt pulley on its own going down the highway on a 2.2 ltr subes bumper (ok- it was a bit of road rage). The ea82 spun it off due to not torqued correct after timing belts. The "walk" is there in mine. I am certain of it. It is no doubt adding to the "crazy" adjectives I have of this engine in this car. I picture it balancing in my head and able to fly up to 10k rpm if intake was capable. I bet it is the sides of the middle bearing worn down- causing a frictionless float.I even had mystery clutch pedal play that refused to adjust- I add this to that middle bearing (it has been good for 18 months after the perfect adjustment finally settled in). The only lube would be what flies out the sides from the middle? Do you ever eat them in high performance? Quote Link to comment Share on other sites More sharing options...

The mains and rod bearings wear, but the thrust sufaces don't seem to. Not to say it's impossible, but it's at least rare. Easy enough to test - try to push your crank in and out. Likely you won't get any play from it. Clutch adjustment has nothing at all to do with the thrust bearing. The transmission input shaft floats in the clutch disc, and in the pilot bearing. It is free to move and so would absorb any movements of the assembly anyway. It is this same effect that allows the flywheel to be resurfaced and used many times - ie: slight changes in the position of the disc and pressure plate relative to the transmission input shaft are not important.

GD Like GD said, thrust bearing wear is not extremely common but I do have an engine that has a lot of horizontal crank movement. Its so bad that when I had installed it into my '78 Brat (EA71 engine), it had a bad rod knock, when the clutch was pushed in, it went away. Ran great except for the knock and the faint smell of burning oil:rolleyes: Quote Link to comment Share on other sites More sharing options...
Steveman09 Posted September 6, 2006 Author Share Posted September 6, 2006 The 164k EA82-T I got used and tore apart to use the block had the Thurst bearing sloppy, I could hear a clunk when moving the crank back and forth Quote Link to comment Share on other sites More sharing options...
