It's just talk, I use them in anything I do that I can buy them for. There is no way a bearing can be "too strong", they could be too hard or too soft but the ACL's are neither. ACL makes Nismo's bearings for them, exactly the same material and everything else as the race series.

A small time Australian bearing manufacturer makes the bearings that were specially engineered for NISMO's 24 hr endurance race program? I think not my friend. ACL don't even offer bearings to such fine tolerances as Nismo. Nismo has always made their own products and I hope always will. I have a fair bit of their stuff ad it is off the highest quality.

Weird where people get these ideas that japanese products are just so good...in comparison to other companies in this world, they are quite average. Alot of times, japense parts for japanese cars are not the best choice. I dont think ACL are actually that small too.

But i had heard that acl also make the nismo bearings....not so hard to believe, holinger were commissioned by nissan to make the racing dogbox for the 32gtrs back in the day.....they probably make some of the best gearboxs for race use in the world, same principle goes for motec/autronic. Hard to believe i know, that Australian companies are actually the best at somethings in this world when it comes to cars and motorsport! Being better then the japs isnt that hard, its the euro companies and stuff that are hard to beat....sometimes the americans too.

Way off topic....but acl bearings, especially race series are used by most top end racers, doesnt matter whether its drag racers, circuit racers, drift racers or sprint cars even road cars. They are spot on. Too hard a bearing is not possible, any bearing that isnt alloy will probably damage the crank if it touches it severely at almost any rpm/load. But as everyone knows if the bearings are touching the crank, then you have another problem which is more then likely bigger then a bearing selection problem. Normal running operation will not damaged the crank.

Yeah I heard the same here. ACL Bearings are the Nismo items. MAHLE just bought ACL too so we should see some more improvements to their already awesome product.

Michael is also right in that the bearing should never touch the crank pin. The oil is what separates the two and if it doesn't, then you have different things to worry about.

ACL bearings are made to the finest tolerances but it doesn't mean they cannot be incorrect. I send back rings and bearings all the time. Make sure you measure everything first and don't just take for granted it will fit to the spec you have purchased them for.

    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
