rod bearings?

[auto alchemist]

so while my SR is out and i already have it somewhat apart i was going to put new rod bearings in it, ive been finding alot of different aftermarket bearings, but ive also had a few people tell me to go with oem bearings (more control over sizes since you can find exactly what you need bye the numbers on the block and crank), so anyone who has rebuilt your SR what did you use, and what is your opinion?

btw the crank is fine, no marks, not rough or anything, it looks to have very low miles

Theres only a couple of different sizes....I had no trouble ordereing bearings...standard or oversized?? Just tell the guy what you want. Clevite 77 bearings are titties. Thats what Ive got. Power enterprises makes bearings as well, but they are high dollar. I have read that people use the OEM bearings but I opted for the better stuff.

i was just going to get standard sized bearings, it hasnt had any machine work since it doesnt need it plus cash is a little tight at the moment, im putting the motor back together myself

I changed 1 rod bearing to a new standard sized oem bearing from a 93 sentra ser(sr20de n/a) . 1 looked like it had some wear and the rest were good.

I'm rebuilding mine with oversize Calico coating ACL bearings. I've heard great things about them. We'll see how they work out.

sorry i have to bring this thread back, i know for sure ive seen clevite bearings for the SR before but for some reason i cant find them now, does anyone have a link to a site that has them?

redtop91, where did you get you calico coated bearings? i may have to check those out too

OEM works everytime for me. Use the FSM and the numbers on the crank/rods/mains to determine what size you need. I like going a size looser myself in every hole if you're going with higher RPM stuff.

well right now i dont plan on taking past the factory redline, im just putting bearings in the stock motor, the old ones looked a little worn so i figured before i put the motor back in my car i might as well do bearings, nobody around my area has got a full season at the track out of their sr swaps because they develop rod knock, so i figured new bearings, a good inspection of the oil system and a greddy oil pan may help me get a little more life out of mine before i have to do a full build.

The stock does the trick for you

Sounds like alot of your friends had tiredmotors and or don't use the proper oil/maintenance.

Best of luck...if you have any questions just ask

Sounds to me it's more like your friends slapped a junkyard motor into their car and expected it to pull 12s with no prep work.

A properly maintained SR will make good reliable power.

these were on stock SR's, theres no way of telling what happened to them before they were imported but it seems like if your doing anything but going in a straight line they blow, around here the guys that drag dont have many problems with them, its all the guys that auto cross, road coarse or drift their cars that have all the problems.

not too mention our local importer is kind of shady, im not going to say any names but from what ive seen there have been alot of people on this site who have had bad experiences with the same place, they say their under new ownership but its the same people.

when the SR was in my car the first time i was using royal purple 5w-30, and a greddy oil filter, i was thinking about going 20w-50 but i havent found any yet thats synthetic, and im not sure if 20w-50 would be too much for the SR or not.

i noticed it says these bearings have more clearance, do plan on running thicker oil?

[redtop91]

Not quite certain on that one. I've been meaning to ask Mazworx how they'd affect oil pressure.

Mobil 1 makes that exact oil. I use that in my 240 for both daily driving, and track use, with no issue.
