Well, im lookin to start doing some upgrades to my ecotec. I kinda went to allecotec.com and found some stuff I will probably end up buying over the next while unless you guys can point me in a better direction.
-Wiseco Forged Pistons 8.9:1CR .020 Overbore or stock bore (mainly wondering if going .020 over is worth it)
-Eagle Forged H-Beam Connecting Rods
-GM Racing Neutral Balance Shaft Set
-GM Racing Hardened Oil Pump Drive Gears (is it needed)
-ARP 2.2L Ecotec Head Stud kit
-Cometic 2.2L L61 Ecotec 87mm Head Gasket .040" or 89mm
-GM Racing Stainelss Steel Intake & Inconel Exhaust Valve Set .5mm Oversize or AllEcotec Stainless Steel Intake & Exhaust Valves
-GM Racing Dual Valve Spring Kit With, Ti Retainers, Spring Seats & Valve Stem Seals
-GM Racing Adjustable Cam Gear Set (not sure one these yet)
-Upper/Lower Engine mounts (probably ordering them soon)
-Comp Cams Blower Grind
-RK Header (anything cheaper out there than this thing? Its a beautiful work of art but kinda pricey)
-Blower setup/w smaller pulley
-Tune
Am I missing anything? Also wondering roughly what i'd be looking at to get my block bored out 0.020 to run those bigger pistons?
Think its worth the big amount of loot? I might be able to get some deals on the GM Racing parts through my mechanic so that should help a little for all those parts.
The rest of the car will be getting lowered on canuck springs, kyb struts, rear disc brake upgrade, nice rim/tire combo (17's), etc.
had a blown ecotec swapped 2000 cavy, now just an 02 Grand Am, and a 74 BMW 2002...
Dont drop the compression if you are going to run a S/C. Stick to the stock 10:1.

-forget the s/c and go with a turbo.
-tune with megasquirt, not HPT
-get the head ported before doing the GMR valvetrain
-get turbo cams instead of blower cams
-i wouldn't worry about the cam gears yet
-the oil pump gears are for if you're using a launch control, as the crank pulley tends to expand, cracking the oil pump gears and killing the engine. although, it is an easy upgrade and definitely worth while.
