rod/main bearings

[hornet7288]

So I just received my 6m remanufactured crank in the mail. The crank was supposed to have been sent with ACL or clevite bearings. While they did send ACL thrust washers, the rod bearings are "ITM engine components" and the main bearings are .50mm over federal mogul bearings. Just making sure, but I should probably get ACL or clevites correct? Just wondering if anyone had ever used these other bearings that were sent with the crankshaft.

Idk about ITM bearings but I just bought a cheap cheap set on rock auto, i think it was like $4.50 or something for the beck/arnley box and When I opened the box I was suprised they were ACL bearings. Just a thought.

 

[hornet7288]

Oh wow that's pretty sweet. I went ahead and ordered some clevite main bearings and ACL rod bearings. I just figured that I would rather be safe than sorry. Especially when it comes to a 7m.

Just saw this thread on SF this morning. Might be of interest to you - http://www.supraforums.com/forum/showthread.php?752601-Reboxed-ACL-bearings

Well, I had no idea. That sucks lol. So I am probably going to get some type of reboxed crap.

 

[hornet7288]

Just need some rings and a gasket set and the build starts

Hornet- You bought the same sizes, right? (.50 undersize)
PS- Are you in the Facebook Georgia Supra Owners group?

The clevites are reboxed ndc bearings which is a good quality bearing I would stick with those there a proven high hp bearing. Acl bearings are quality if I was building a 2j thats the bearing to use but the 7m version are reboxed not true Acl and Ive been told that the quality is not there. According to rich from sip the Malta dragster was using clevite bearings also. One more thing buy from a reputable source to much fake China crap being sold I personally buy them from summit racing you may pay a little more but you know what your getting!

 

[hornet7288]

Yea I purchased the same size for the rods and mains. I am having a really hard time finding .020 over piston rings. Any suggestions? I ordered some on ebay and they returned my money saying they were out of stock and did not know when the next shipment would arrive from NPR.

I am not in the supra group on facebook...I used to be, but I got rid of my facebook.

 

[hornet7288]

Or if anybody else knows of another brand of 20 over rings that are quality that are more available than NPR rings.

Too bad you're not on FB anymore. We have local mk2/mk3 meets on a semi-regular basis.

What part of Atlanta are you in? I'm in Lawrenceville. LMK if you need anything for your build.

 

[hornet7288]

Im actually in Savannah right now...finishing school here then hopefully headed back to the atlanta area.

 

[hornet7288]

Are the ITM engine component rings decent rings?

 

[supraguy@aol]

At least as good as NPR, I would imagine.

Or try these.

[hornet7288]

Sweet...any opinions on moly vs chrome/steel rings?

I believe the ITM ones are moly and the engine tech are chrome.

 

[supraguy@aol]

No experience really.
What sort of motor are you building? If it's just a mild upgrade, I'd go with ITM.

 

[hornet7288]

Yea at most I may do 550's and a 57 trim turbo. No more than 400 WHP.

Mine were real ACL bearings i got from rock auto. The beck/arnly box looked about 20 years old. I had ACLs in it before which I still have the box for them and they were extremely old as well, The new bearings were identical to the ones I removed.

 

[hornet7288]

Rock auto has the following:

Sealed power - $ 91.79
ITM engine components - $ 55.89
DNJ Engine components - $ 34.99

I hate to pay 92 bucks if the sealed power ones are really no better than either of the other two options.
