Goodhart's budget beater 1g

[goodhart]

So, I will be putting together most of the shortblock on Friday with Kerry. Quick question, what do some of the experienced builders on here suggest for piston ring end gap?

Stock spec is as follows:

No. 1 0.25-0.40 mm (.0098-.0157 in.)
No.2 0.20-0.35 mm (.0079-.0138 in.)
Oil 0.20-0.70 mm (.0079-.0276 in.)

Limit:
No. 1, No.2 0.8 mm (.031 in.)
Oil 1.0 mm (.039 in.)


Now, I plan on running lots of boost from the 16g and possibly nitrous down the road. I know that more heat/boost/timing/etc = wider gap. My question is how wide?

I have read from a few builds on here that .018 and .021 work well for a higher boost motor.


Thoughts? Steve? John? Swanny? Shane?
