I am in the process of rebuilding a D16Z6. I actually have a bare block and crank from a different D16Z6. I was hoping to use OEM bearings but realized that maybe the machined sizes might not match?
I am showing the mains as D D C C D on the bare block and B C B B C on the crank if I am reading the crank correctly. Does this mean I will have to run aftermarket bearings?
Best bet is to plasti guage them and see what the clearences are..if they are tight (re fsm), i wouldnt use them, if they are a little loose go for it.
I wouldnt want much more then 0.0025" on the mains and 0.0015" on the rods myself.
Compair the block you have and the block they came out of.
Then compair the crank you have vs the crank the bearings came off
But for not much money you can get new acl or king main bearings.

Yeah IF you can see the colors on the oem bearings then yes you only have to check your block and crank and see what colors they need and if the ones have will fit within what you want for clearence.
If you cant see the colors on them. You need the block and crank they came from in order to see what they are for size. Or one can always measure them to check thickness.
Simplest way is buy 15$ plastiguage and check it out. As long as they fall with in the spec you want you can run them. Even if one main is 0.002" and another is 0.001" they just need above 0.0009" and less then 0.002
And even with acl bearings you are going to want to check them anyway before assembling the engine.

You can use OEM bearings, and I would recommend them if the sizes you need are still available. Checking with plastigauge is a good idea, too.
The numbers on the crank are for the main bearing journals, the letters are the rod bearing journals. Using the factory charts below you can build an engine with more accurate clearances than using 'one size fits all' third party bearings, unless you have the crank turned and the block bored by a good machine shop. I built a D16A6/Z6 minime in 2012 using factory bearings and it is still running great.
So I finally got in the Ishino Stone set which I was pretty impressed by. The only problem is that since its a Japanese Brand, the instructions are in Japanese and I don't have a way of telling what gaskets are what. Can someone help identify the gaskets from this photo?
I have my newly built 1989 D16A6 running well and have accumulated 2300 miles at the present time. I went with forged CP pistons at .020 overbore and stock rods. The head was freshened up as well and milled .010 and I have a Y8 head gasket to increase the compression. After the initial break...
I am rebuilding a D15B7. Would there be any benefit of running a D16Z6 crank pulley (for reliability)? Or should I stay with the B7 pulley. From what I can tell my B7 pulley in not dampened.
Hey guys, I hope everyone is having a great day. I wanted to know what everyone's opinion is on camshafts. I'm looking at getting Brian Crower Stage 2 camshaft for my d16y7. I want to get Brian Crower, Skunk2, or Blox racing. Which would be the best.
It looks like the AEM Z6 fuel rail has been discontinued and I'm wondering if there is another clear front runner to replace it if doing a Z6 build? I see a lot of generic rails on Ebay, but not sure I want to risk my build on those. Any help would be appreciated.
