Anyone have any input on the pros and cons for this...I know Honda guys use OEM over ACL but what about toyota?

 

Paul jsut bought some ACL, IDK though. The oil journal may be a little bigger.

 

how many scions have you heard of with spun stock bearings? now how many with acl bearings?

 

some info from acl's website.



Engine Bearings (Aluglide)



The new generation engine bearings – smart, strong, tough.

Aluminium Tin materials have been around since the 1960s. They have traditionally been the choice of Japanese and European manufacturers for low load, gas, passenger cars. As the loads developed by high horsepower late model engines increased, so too did the need for a stronger bearing material. Copper lead Trimetal bearings have been the answer for higher load applications and today make up ACL’s current range of Duraglide® and Race Series engine bearings, but as the world becomes more environmentally conscious, the need for lead free engine components has increased, without sacrificing the load carrying capacity required for modern engines.

The addition of silicon as an alloying element to the Aluminium Tin family of bearing materials has elevated it to the next generation of performance materials. This is currently the choice of most Original Equipment (OE) manufacturers as the global mandate to have Lead free vehicles is enforced. In keeping with these global trends, ACL Bearing Company commenced a development program in the late 1990's to provide a high strength aluminium based lead free material that provided a suitable alternative to traditional bearing materials & to provide all customers with a solution to their tribological needs.

The introduction of Aluglide™ bearings is another example of ACL’s commitment to understanding and adapting to customer requirements. ACL’s new Aluglide™ engine bearings combine the proven advantages of aluminium tin metals with silicon to make this the very latest generation high performance alloy and have met with global response which proves these Australian developed and made components are at the leading edge of a competitive international industry.

Made by ACL Bearing Company in Tasmania, Aluglide™ aluminium tin silicon bearings are sold to both local and overseas markets. They are fitted as OE in Australia and have been sold through the aftermarket in the USA for the past 18 months. In the short time since being released, Aluglide™ has met with great success from both OE built engines and those rebuilt in the aftermarket. Aluglide™ bearings are ideally suited to general purpose applications (passenger cars and light commercial vehicles) and selected applications are now available in the Australian aftermarket. They are easily identified by the slick silver packaging featuring the Aluglide™ logo which will become more widespread as changeovers from Duraglide® to Aluglide™ occur progressively. For engines that require higher load applications and are subject to more demanding operating conditions (e.g. performance/race engines), ACL will continue to range the Copper Lead Trimetal Bearings through the Duraglide® and Race Series ranges.

One of the reasons why Aluglide™ has been such a positive achievement is due to ACL Bearing Company’s in-house research & development, further refining the alloy for a winning advantage over the competition. It features a strip cast microstructure which is the result of the inclusion of alloying elements and careful heat treatment. This gives superior bonding surfaces, particularly between the aluminium bond layer and the steel which are then optimised and remain that way to handle long term maximum loads. Put simply, the new bearings can take a higher load in the way the stress is transmitted to the steel. Additionally, the harder surface of the tough alloy gives substantially reduced wear and minimises any possible shaft abrasion, resulting in an extended service life.

 

I have been using ACL for a long time and have nothing but excellent results with them. In fact I usually take them and measure them then bring them to the tighter end of spec and even them out with a low friction coating to my specs. That way you get the clearances perfect for each journal and get the benefit of a coating on the bearing. Works extremely well and surprisingly inexpensive.

 

good info.

 

nice info!

 

i am currently using ACL bearings in my motor.. i am very happy with them.. do not use toyota bearings for built motors.. they are ok but can take a crap.. i know from personal experience..

the journals are bigger and much smooth then the toyota ones..

Honda bearings are made from the same grade materials as ACL which is why most honda guy will prefer regular ones over honda ones since its cheaper and you get the same exact product... OEM honda is sometimes stronger and greater then aftermarket parts..

in our case i would recomend anyone and everyone doing a build to order ACL bearings...

food for thought... it is possible to interchange some valve train components with k series components...

 

You may also want to check out Dezod which is now carrying the Clevite 77 bearings. I have no idea anything about them or any bearings really but it's another option. They didn't have them when I ordered my stuff. Maybe Paul can chime in with some info to help sell them.:D

I got ACL i was just posting for a debate

 

Well in that case I think "zpi race bearings" are the best.

 

lmao when ZPI got every one of there parts from Race Engineering lol

 

Ding dimg!!!!

Clevite is EXCELLENT on quality. Being part of Mahle (many of you know their quality and OEM work).........Here is some info on them:

Clevite® engine bearings have an extensive, long-standing history with racing. Our Clevite product has been winning NASCAR®-sanctioned races since 1948, and is the exclusive bearing of NASCAR Performance.

We offer the most extensive line of performance engine bearings in the market. Our range of performance engine bearings is designed to provide winning results even in the most demanding applications. Our involvement in INDY, NASCAR, ARCA, NHRA and IHRA racing as well as other forms of motorsports have proven Clevite to be the leaders in engine bearing technology both on the track and off.

Since our development of the first precision insert-type bearing in 1929, Clevite engine bearings have set the pace for engineering quality. Clevite engine bearings are built above industry standards for strength and durability. The majority of Clevite performance engine bearings utilize a superior TriMetal™ design first developed by Clevite 50 years ago and perfected over time. This design incorporates the strength of a copper-lead alloy layer on a precision steel back and finally, a precision electroplated white metal "babbitt" surface layer. TriMetal is an ideal design, producing a degree of conformability, embedability, slipperiness and fatigue resistance, not found in many original equipment and competitive bi-metal bearings. [Selecting Performance Bearings]

All Clevite engine bearings manufactured by us are color coded for quick and positive identification of undersizes. The possibility of confusion or errors in installation is virtually eliminated by checking the color code on the side of each bearing.

The exclusive Clevite® TriArmor™ engine bearings feature the industry's only engine moly/graphite treatment. This sophisticated blend, in a low friction PTFE polymer base, offers extraordinary protection and lubricity. Enhanced wear characteristics increase bearing life in race engines and high performance street engines. [TriArmor™ Link]

Now, high performance engine builders can enjoy the strength and durability of the legendary Clevite® TriMetal™ bearing construction coupled with the latest in coating technology - right out of the box.

It's no wonder that Clevite is used more often than any other bearings in cars worldwide and in most race cars. In addition, Clevite has been in most winning engines at Indianapolis and NASCAR. And that's why, year after year, quality engines everywhere turn on Clevite bearings.

 

I'm in the process of doing research on building my motor and this is my first build ever with any motor period. So now I'm debating if I should go ACL or Clevite

 

You should go with ACL!

The place thats building pauls motor uses there own specs, and now pauls stuck with the brand new ACL's that he bought. hit em up!!!

 

i'm confused.....hit who up?

also is there an ACL website? Does anyone have the part number for the bearings and such?

 

Hit me up. I have brand new bearings (main and rod) that I don't need cuz they are being supplied by the builder. Here's a link to my sale of them...
