I am new to this board and interested in getting an opel kadette rallye. I had one 30 years ago and think it is time for another. My question is if I get one with the 1.1 or 1.5 liter engine and 4 speed will the 4 speed fit to a 1.9 l engine as that is what I really want. I intend to open the intake and more so it will breathe best. I want the German built opel so am I looking for 68 to 73 years? Thanks in advance.

Well, the 1.5 litre Kadett was imported only in 1968, and it's a rather rare beast comparatively speaking. However, the 1.5 litre is of the same engine family as the 1.9 litre (both are 'cam-in-head' engines), and the transmission and the rear axle are interchangeable. The clutch is actually slightly smaller for the 1.5 version , but they interchange with the 1.9's anyway.

The 1.1 litre is an entirely different beast. Different engine, different tranny, different front leaf spring, different rear axle, smaller rear brakes, etc. Harder to find parts too. At least with the 1.9, most all of the GT hard parts will interchange.

If you specificly want a Kadett Rallye, the following is the model differences.

67 1/2 year was the A model style, different then the B model of later years. Limited to 1.1 engine.

68 Rallye Start of the B models. Had 1.5 engine as standard. 1.9 optional.

69 & 70 Rallye went back to the 1.1 as standard, with 1.9 as optional. The 1.5, as Bob said, was dropped.

71 & 72 Rallye Kadetts weren't available, but standard Kadetts were. The Rallye badge went to a Manta model starting in 71.

thanks for the information guys. My 68 rallye was the 1.5 and fun to drive. so the 1.1 is different entirely as is its transmission. So if I were to get one with 1.1 and changed to the 1.9 I would also need to change transmissions- I think this is what you said. There are many GTs for sale but you dont see that many rallyes in the 68-69 years and that is what I want. however I suspect the GT is even more of a performer and fun to drive although I have never driven one. I will keep looking.

If you go from the 1.1 to any CIH engine, you'll also need to change the rear end as the 1.1's is not strong enough to take the torque.
