Will 0.020 over bore on a gen 2 be ok?

[NASteve]

So it begs the question, if you're not going 4 digit power, what's the point of going .020" over? What are you really gaining? Unless you've gotten some steal of a deal on pistons that are overbore (even then) I don't see the point in it unless you have big big plans and are trying to squeeze out every last drop of power.

Possibly clean up from some damage or just to give the rings a fresh surface to seal to, .020" won't make significantly more power. But when done with a tq plate properly the bores will be round so sealing with new rings will be improved and more power can be found through all of that over factory machining.

It's a gen 2, so no plasma and I'm not sleeving it...
It has the water jacket supports though

or if it takes .020 to clean up the cylinder

Yea mine took .020 to clean the cylinders

The only other machine works that you should seriously consider is machining for 12mm head bolts. You can use gen 1 or gen3 bolt/studs

What kind of rods and pistons are you planning?

10:1 compression je pistons and manley h tuff rods

I would not use je for what you are planning. You want a full skirt piston so it’s very stable je is light but can be unstable.
H tuffs are fine but over priced and heavy. Callies compstar are my rods of choice

Ah that's not good to hear... what piston would you recommend

Ross, dss, Manley has a set that they sell through mmr. Mahle,

Get a gas ported piston or you can gas port them yourself

The je pistons are laterally gas ported

The je pistons are laterally gas ported

If the je pistons are full skirt and gas ported go with those
