Personally, I wouldn't use anything but OEM rod & main bearings.
The nippon bearings are most likley similar to ACL or King, which only offer one size for a standard (non machined) crankshaft. While I am sure the minor difference in oil clearance wouldn't harm everyday operation, there's a reason honda is so percise with their thickness. Balancing, Oil Pressure, etc.
When your car was assembled, they match the sizes below to every journal, in order to fine tune a percise oil clearance. Most aftermarket bearings are the same as OEM green size, which is the most universal to every application.
You could just take the crank and nippon bearings into a machine shop and have them match the journals to the bearings, to achieve OEM like results.
Main Bearing thickness by color
Blue 2.013-2.010 mm 0.0793”- 0.0791”
Black 2.010-2.007 mm 0.0791”- 0.0790”
Brown 2.007-2.004 mm 0.0790”- 0.0789”
Green 2.004-2.001 mm 0.0789”- 0.0788”
Yellow 2.001-1.998 mm 0.0788”- 0.0787”
Pink 1.998-1.995 mm 0.0787”- 0.0785”
Red 1.995-1.992 mm 0.0785”- 0.0783”
If you already knew this, then disreguard. I just wasted money having a crank re-ground, and couldn't achieve OEM type results with oversized bearings. Just trying to save you a headache.

So what bearings do you guys recommend? I tend to be a little child and beat on the motor a whole lot! I really don't like hitting past 7900rpms 8 outta 10 times. But I was thinking going turbo. But I got into my cusins 92 si K20 and man for an all motor car its enjoyable. IDK

It's not the quality of the after market bearings that concerns me, it's the fact that they only make one size for a standard crankshaft. Honda calls for an array of the sizes above, depending on the engine.
Traditionally, and still for most other engines, there is only one standard sized bearing. They step up in increments of .010", for a re-surfaced crankshaft. You really need all the sizes above available in order to get the precise, even oil clearance honda calls for.
You won't know exactally what size OEM bearings you need, until you pull the oil pan at least. You use codes on the crankshaft and block, match them to a chart in the helms and order bearings accordingly.
