I have a 99 camaro 3.8L A4. I spun a rod bearing and was planning on rebuilding the engine but my buddy has an extra '03 3.8l engine but the supercharged version he will sell for cheap. my question is could i use that block and swap in the pistons from my motor to make up the compression differance? also what are good pistond rings to use?
thanks

I would just put your top end on that short block. I wouldnt try to put your pistons in it unless you are comfortable checking all of the clearances. You could however run a thinner head gasket to make up a little bit of compression. Or leave the lower compression to set you up for a turbo someday :naughty:
what if i use the supercharged crank in my block with new L32 Powdered metal connecting rods would that work as long as i plastigauge it or would it need to be line bored?
also I would think as long as the cylinder walls are not tappered in the doner block the pistons should fit just fine with new rings right? correct me if im wrong im just trying to figure out whats going to be easiest and most cost efficent

The old L32 rods should work. As far as taking the path of least reistance; I dont know if you have taken apart a 3800 block before, but taking the main caps off is work. To mock it up with plastigauge your going to have to tear down and build up twice.
ok so is the "03 engine a L32 or L67 whats the differance? does any one have the link to all the L motors and differances and what cars they came in?
the guy im gettin it from says its an L67 that came with the fardened internals if so than i would not need new L32 Powdered metal connecting rods from ZZP right also he says it only had 35K miles which is half what my engine has.
L32/L67/L26 all have L32 forged L32 rods(powered coated) and same crank and internals except for the lower compression on the supercharged engines. The supercharged engines have different heads , L26 N/A engine has same heads as L36 but they have bigger exhaust valve stock on their heads. Still need to use L36 oil pan, upper/lower intakes and oil filter housing and either L36 heads or L26 heads to make everything work.

I thought they only went to the powderd metal rods for the series 3
Heres some input, should clear up some questions I hope.
Powder metal connecting rods are found stock in 04 and newer GM 3800 engines. The L32 rods are hot-forged powdered metal. Powdered metal is more durable and reliable than conventional cast iron, delivering greater anticipated life. As importantly, the powdered metal rods are stiffer than the cast iron parts they replace.
Series III
The Series III motors include many changes. The upper intake manifold is now aluminum on the naturally aspirated models. Intake ports are mildy improved, 1.83" intake valves (instead of 1.80" as on Series II) and 1.52" exhaust valves were introduced in 2003 engines, just before switching to Series III. Electronic throttle control is added to all versions, as is returnless fuel injection. Stronger powdered metal sinter forged connecting rods are used in 2004+ supercharged, and 2005+ naturally aspirated engines, instead of the cast iron style from Series II engines. Emissions are also reduced. In 2005, it was the first gasoline engine in the industry to attain SULEV (Super Ultra Low Emissions Vehicle).
Also note that Series III engines are the base for any 3800 produced for the 2004 year and up. This means the same block, heads, & connecting rods apply to any remaining Series II engines made after 2004 also. The difference is that Series III engines received the new superchargers (Generation 5 - Eaton m90 - if equipped), intake manifolds, fuel systems, and electronics.
L26 Naturally Aspirated
The L26 is the Series III version of the 3800. It is still a 3.8 L (231 cu in) design. Compression remains at 9.4:1 as with previous L36's, but the aluminum upper intake (2004+) and stronger connecting rods (2005+) are the primary physical changes. The powdered metal connecting rods were meant to be introduced in 2004 along with the L32's, but the GM plant in Bay City, Michigan that supplies the Flint, Michigan plant could not achieve the desired production dates in time for that engine year.
This engine was used in the following vehicles:
2004-2008 Pontiac Grand Prix
2005-2009 Buick LaCrosse
2006-2008 Buick Lucerne

Hello every one, ozzy here ive been looking at this page for weeks now finally joined. So my question is why is it that every turbo build forum just ends...
Just ordered some Toyo 315/35/17 tires for my 17x11 rims. Hopefully I can get them on the beginning of next year. Will post pics.
