Can I replace my '02 3.8 with the newer engine?

 

thats wierd that the gtp engine puts out more horse power than the monte carlo, because it seems that my car is quicker than all the gtp's in town....i wonder if it was just a typo from gm! :-p lol
as far as i know the engines are exactly the same...i think the monte weighs a little less than the grand prix though...

i believe its just an upgrade in the supercharger as the series 1 supercharger had i believe 220 the series 2 was 240 and series 3 260

 

 

HOPE THIS HELPS
Supercharged
The Series I supercharged engine went through many internal changes and the horsepower changed rapidly between the time it was introduced and the time that the Series II L67 was introduced. The supercharger was manufactured by Eaton, exclusvely for the GM 3800 engine. HP was rated at 205 for 1992-1993 engines, and 225 for 1994-1995 engines. The additional horsepower was gained by using a larger throttle body, and epoxy coated supercharger rotors, improving efficiency. The 1994-1995 utilized a 2.85" pulley versus the 2.55" pulley used on the 92-93 supercharger.
Applications:

Series II
Introduced in 1995, the Series II is quite a different engine. Although the stroke for the 3.8L engine remained at 3.4in (86mm), and the bore remained at 3.8in (97mm), the engine architecture was vastly changed. The piston connecting rods were 1in (25mm) shorter, so the crankshaft was redesigned. A new intake manifold improved breathing, and a new cylinder head had larger valves. The result was 205hp (153kW) and 230ft·lbf (312N·m), better fuel economy, and 26lb (12kg) lighter overall weight. In 1999 the 3800 Series II in the Chevrolet Camaro and Pontiac Firebird received a new throttle body with Electronic Throttle Control.
The 3800 Series II was on the Ward's 10 Best Engines list for 1995 through 1997.


L67 Supercharged
[/align]The L67 is the supercharged version of the Series II L36 and appeared in 1996, one year after the normally-aspirated version. It uses the Eaton Generation 3 M90 supercharger with a 3.8" pulley, a different throttle body, fuel injectors, cylinder heads, and lower intake manifold than the L36 uses. Both engines share the same engine blocks, but compression is reduced from 9.4:1 in the L36 to 8.5:1 for the L67. Power is up to 240hp (180kW) and 280ft·lbf (380N·m) of torque. Final drive ratios are reduced in most applications, for better fuel economy and more use of the engine's torque in the low range. The engine is built in Flint, Michigan. The engine was certified LEV in 2001.
