Alright, crank/block codes call for

1). Green
2). Green
3). Yellow
4). Yellow
5). Yellow

Installed set of ACL standards. Plastigauged. Got these results:

1). .030mm
2). .050mm
3). .050mm
4). .050mm
5). 0.24mm

Now, one is "ok" and in spec, however a touch on the tight side. 2,3,4 are all "ok" but 2 and 4 are at the service limit, loose. 5 is a definate tight fit, but again, in spec. I am honestly not too comfortable with these results. Now, assuming that ACL's are all = to Honda green, here is what I feel I need for this engine:

1). Yellow
2). Black
3). Brown
4). Black
5). Yellow

My question now. Would you either run the ACLS, order the OEM using the block code numbers, or order the OEM using the newly formed list based off the ACL plastigauge results? This will be a daily driven, "weekend warrior", setup..

 

If this is a stock rebuild then I would run the honda spec from the codes on the block and crank.

If you are looking for some additional performance I would shoot for 0.002" clearance by spec'ing the bearings according to Earls chart.

I think plastigauge is fine for checking but not for spec'ing. <rhyming>

Its not stock. ITR pistons and rods in a GSR bottom end. Did 190whp with the last setup however the rings were *** and thus its torn down in the garage now. So you are saying .002" is fine, meaning my clearances are good on 2,3,4 and "not so good" for 1 and 5, am I with you?

Yes, that is correct.

Alright. Now, running this "loose"... Should I worry about longevity of the engine? Run thicker oil?

No, If you plan to spin it up alot. This gives your the extra assurance the motor is going to last. I run 5W30 all the time.

I'm not sure I follow what you mean with your reply. I shouldn't worry about running it loose becuase its better for high rpm, or I shouldn't worry about running thicker oil? I ordered all the OEM bearings that it calls for with the crank/block codes. I am going to see how things clearance using OEM. Who knows, perhaps the ACL's aren't = to greens like everyone says.

 

Sorry about being vague but no don't run a heavier oil. And yes loose is better for high rpms.
