Looking for a new motor for my Kadett.. I considered a lot of motors, and was leaning towards the 2.2L Opel motor.. Then I came across this motor.

The straight-4 LK5 engine is sold as the Vortec 2800 in GM trucks. Like its Atlas brothers, the LK5 has dual overhead cams, and shares their 93 mm (3.7 in) bore and 102 mm (4 in) stroke. The LK5 displaces 2.8 L (2770 cc, 169 cu in) and produces 175 hp (131 kW) at 5600 rpm and 185 ft·lbf (251 N·m) at 2800 rpm.[2] Engine redline is 6300 rpm.
It is used in the following vehicles:
2004-2006 Chevrolet Colorado
2004-2006 GMC Canyon
2006 Isuzu i-Series

Dimensionally its almost a dead match for the Opel CIH motor. But it is a bit higher due to the Air Flow Meter and CIH on top of the motor. Motor mounts are in the same location.. width is about the same as is length.. etc.. The oil pan is similar to the Opel with a rear sump pan.
Best thing its cost complete is under $800 with low mileage at Car-Part.com--Used Auto Parts Market and for about $400 my guy that builds the LS harnesses I sell. Can modify the harness and reprogram the computer making that part of the job easy.
I did look at the I-5 (By the way tends to be CHEAPER.. more of them out there)

The L52 (also called Vortec 3500), is a straight-5 truck engine. It displaces 3.5 L (3,460 cc/211 cu in), with a 93 mm (3.7 in) bore and 102 mm (4 in) stroke, and shares much with the rest of the Atlas family. Dynoed at the flywheel it produces 220 hp (164 kW) at 5600 rpm and 225 ft·lbf (305 N·m) at 2800 rpm, while producing 179.13 hp at 6001 rpm when dynoed at the rear wheels. Engine redline is 6300 rpm.
It is used in the following vehicles:
2002 Chevrolet Bel Air concept
2004-2006 Chevrolet Colorado
2004-2006 GMC Canyon
2006 Isuzu i-Series
2006 Hummer H3

Its 6 inches longer.. which MAY fit a Manta.. but it doubtful it will fit my Kadett..
I will keep you all informed. Once my GTO goes next weekend I will be getting the motor and starting on the swap.
