I just bought a car about 5 weeks ago. Its a boosted ek hatch on 12 psi and e85 b18c1 81.5mm 12.5-1 comp ratio, cp pistons, eagle rods, acl standard bearings, skunk2 valve train, hx35 holset, ect ect ect. Anyways i bought it on a saturday and it blew up on sunday lol ya i should of just built one myself but the next day is started to knock so i took the head off and the head was good. So i dropped the oil pan and it looked like a gold mine with all the gold shavings in it. So i took the pistons out and the number 1 and 2 piston rings the middle ones are like all fallin apart and like shattered. What i need is to no what new bearings i should get and piston rings. I have been looking everywhere for both and I cant find any. I want cp piston rings "Preferably the best ones they have to offer" and acl race spec bearings. So please someone send me a link to some acl race spec bearings that are .010 bigger because I am gettin my crankshaft machined and they are prob only goin to take of .010 off of it and a link to some cp piston rings 81.5mm bore. thanks!

 

it was knocking because #4 rod bearing spun if you were curious.

 

need to check all the bearing clearances, main and rods. need to get some plastigauge to find the correct size bearing. more than likely the acl race bearings wont be the right size or at least not all of them

 

well if all the bearings were the same size before the rebuild just standard b18c1 size and they machine all the lobes or just the ones that need it .010 off wont i just need that one bearing .010 bigger or do you mean measure it after the crank is done?

 

you have to measure after all work is done. there's a reason oem has so many sizes.

 

ok so slap my old bearings on it and see where am at ok thanks but what about rings? I cant find any that are 81.5mm CP rings. also another question. if my bore is 81.5mm will i need to buy a 81.5mm head gasket?

 

make sure when you installing the pistons and rods put a vacuum hose over the rod bolts so you wont kink the crankshaft

 

you can slap your old bearings in but you need to know which 2 bearings go to which main, same thing with rods

 

ok if my bore is 81.5mm do i need a 81.5mm head gasket? and i need help finding rings for 81.5mm bore
