ok guys blocks painted rings are gaped (had to redo it myself since he didnt do it where i wanted)..

anyways i plastigauged my crank today and i was a bit dissappointed and need advice..

stock clearences are .0008-.0018 limit .004

my clearences where (1.) around .001-.0015 (2.) about same. (345)but the last 3 were more in the .002-.0025... wish i had a bore gauge to make sure but i did it twice and 3 4 5 fit more in the .002 + range...

do you think this is ok or should i attempt to replace those bearings with a thicker grade from nissan (im using acl race now std size). would it be alright to mix the 2 brands. is it ok to run the clearences like this.. i plan on mostly drifting the engine.

please point me into the right direction..

You can get away with it as the crank allows more error than oem specifies. The only problem, do you feel comfortable at taking a chance. You can always get a reconditoned crank or have your crank turned and re-sized. I take a lot of chances on odd clearances and I get away with it, ut in reality if it fails I know it would've been because of my laziness. So it's going to be your call "champ" .

dam i hate these type decision lol... im going to redo it one more time cause after reading i think i put the shells in wrong, the bearing with the full groove goes in the block and the shell without the groove goes in the main cap right.

[zero_gripS13]

ok so i bought some mics and gona try to get some better measurement, im also gona plastigauge again..

just to make sure the full grooved main bearing goes in the block and the non grooved goes in the cap right?

LOL..Don't feel bad, I've done this before. Hell, I've put a headgasket or two on backwards as well. None with fatal results for the motor, but nonetheless I screwed-up. Rushing causes mistakes and please don't try to do it all in one day. Refresh your mind and come back to it and the results will be to your liking.

f its a standard uncut crank you can use numbers stamped on crank and block to get the corresponding OEM clearanced bearing for each journal.

yea dee lol the bearings wherent labeld top or bottom so i just figured grooved on the cap and other on block and then check on acls website and oops backwards lol..

also i was running acl race bearings only come with one standard size which is like grade 0 the smallest one which kinda sucks im gona check my numbers and see which grade i need.. i might have to get nissan bearings we will see after i recheck again

[bentvalves]

yeeap its why i always just go straight for the stamped numbers, makes life easier like whoa

acl race are great bearings i figured i throw em in they were cheap and a nice design built to handle stress but nissan are great too just more expensive lol.
