Contemplating a D15B4 rebuild. Anyone see anything wrong with the following?

New stock PM3 pistons 0.020" oversize, stock head gasket,
New bearings, oil pump, etc.
0.060" off head (should bring comp up to 10.8-11:1) and recon (maybe mild porting)
Bisimoto stage 2 non vtec cams, springs & cam gear
40 or 45mm dual carbs (webers or dellorto's)

Also with the above, how much power would you expect? 80-85kW or am I hoping for too much.

I do, pour money into a better motor, Vtec head on a Y4 block....

So little gain.

You'd need to tune it after to get maximum benefit.

May as well do a b series swap.

They're getting cheap these days. Would cost roughly the same as what you're planning to spend. Except it would outperform what you're planning to do.

Well aware of that. But I need to keep my block and head for class restrictions.

Building loosely to Type3A/3J/NM3A, motor swap = min weight limit penalty.
Not looking to break any records just out there for fun.
