Hi guys,

I am building an 1.7 16v engine from different parts (I didn't have a complete engine, so I am building one from two different uncomplete engines) for my 145. As I am going to put in motronic m2.10.3 ecu and wiring harness, I need a photo of a 145 1.7 16v flywheel, because I now have one for the 8v boxer and one for the 1.7 16v from 33, but neither of them will fit, the crank sensor ring gear is apparently different. I went to a junkyard and there is probably the right one, but we can't recognise it, so please if anyone has the picture it would be great, tnx

ok, made some more, enjoy.
sensor is 90 degrees till TDC if looking from the back of the engine (technically it detects two missing teeths 270 degrees till real TDC).



this is rotated flywheel to show real teeth detection:



some engine assembly photo, maybe will help (looking from the back of the engine / from driver's view):

Also, don't forget that the clutch back plate is specific to the 145/6 flywheel. A normal 33 16v clutch will not fit.

You could also fit possibly a 220mm friction plate - but this would have to come from another car. I used to remember which friction plate it was (vauxhall 2.0 something) but I can't quite remember. The 145/6 flywheel friction face is wider that the 33.

during my 8v boxer built up, i bought 16v flyhwheel and since none of the machine shop near my workshop willing to do the flywheel gear swap.. i resort to skimming the 1.6 8v flywheel. I have skimmed my 1.6 8v flywheel to the design of the 1.7 16v flywheel. found out that the 8v flyhweel is weight at 8kg while the 16v is at 6kg.

The gear for 8v also short by 1 tooths if i remember it correctly.

so now with 6kg flywheel and match with 17 16v clutch kits set, my 146 boxer 1.6 8v could do better sprint .. and the only set back is that the top speed only up to 180kmh....
