I need many specs for a 1994 Chevy cavalier motor. To name all the things i need: bore size, Stroke length, ignition firing order,connecting rod bearing clearance, main bearing clearance,crankshaft run out, connecting rod journal diameter and maximum allowable taper/out of round for it. Main bearing journal diameter and Maximum allowable taper/out of round for it. Piston size, skirt clearance, ring groove clearance, ring end gap. Connecting rod bore out of round. Maximum allowable Cylinder taper/out of round, cylinder diameter. Valve spring Square spec, Valve spring Tension spec. Cam journal diameter/ taper/ out of round, cam lobe lift, camshaft run out. thanks

To be honest for the work involved it would be easier to just swap out the 1600cc engine for a complete 1800cc engine. Engine cc can be set by different things. Piston bore, piston stroke, connecting rod length and so on. 1800cc pistons might simply be the wrong size for the cylinder bore.

spec for 4m51 ==5.2 l direct injection diesel
spec for 4d32 ==3.5 l direct injection diesel
bore /stroke 104 x 105
specs for 4d33=4.2l
bore stroke =108 x115
you problem is the length of the stroke which is governed by the throw of the crank pin ( distance from the center of the main journal to the center of the con rod pin)
As there are significant differences in torque ratings between the engines it is possible that the bearing sizes will differ and the blocks will be different
That being the case , it is doubtful if the heads are interchangable
Engine reconditioning companies will possibly have all of the specs for bearings , pistons and heads and you may be able to get a ready comparison or go to en.m.wikipedia.org to get a better idea of the differences

Connecting Rod's are VERY SPECIFIC for each engine. In Addition to getting the Right STROKE, Piston Pin Size, and Crankshaft Size, you need to make sure to get the Correct Bearings for the Crank. If you are not going to remove the Crank from the Engine, your BEST Option is going to be Purchasing a NEW Push Rod.

The firing order is 1-2-3-4-5-6
Cyl #1 is front left when looking at engine front to back
left coil pack connects to cyls. 5-2
center coil pack connects to cyls. 3-6
right coil pack connects to cyls. 4-1
It doesn't matter which connector on the coil you use just that the cylinder is connected to the proper coil pack (the coil fires both plugs at the same time, twice per each full 4 stroke cycle)
