I guess I would say Wikipedia it, I mean what do you want to know that isn’t a bit obvious? Similar drivetrain to the Opel GT, it’s what they based it on. 66-67 were the same style as the European Kadetts, but the 68-71 Kadetts in the US were a more deluxe model called the Olympia A in Europe. In 1968 theee engines were available, 1.1,1.5,1.9. A 1.5 was standard engine in the Rallye model. 1.9 was optional. Used to think you couldn’t get the 1.1 in 68, but it shows you could order it, and certain models came with it.
I have read things about the trans tunnel being different between 1.1 cars and 1.9 cars, as well as autos. The core support/radiator mounting area being different between 1.1 cars and 1.9 cars. Is the rear axle the same as my manta? Is the 4 speed the same as was in my manta? Does it share anything with the manta? What was the standard rear axle ratio?
Transmission tunnels there were four different tunnels. A 1.5-1.9 4speed, 1.9 Automatic tunnel(69-71). No auto in 68. 1.1 standard shift, 1.1 sport shift. The rear end is not the same as the Manta, somewhat internally but it is identical pretty much to a GT rear differential. The 4 speed will be close as well, but a Manta used a different bell housing and shift tower may be the same. It will have an external reverse switch. It’s interchangeable, but the you would have to retain the Kadett bell housing. The block is going to be different, only a 3 bolt starter will work if it has the original engine in it. Later 70 and up had two bolt starters and will interchange. GT was not affected by this change. Core support for radiator is different as well between a 1.5-1.9 and a 1.1 car.
Kadett had a few rear gear ratios 3:18 3:67(Rallye) 3:44(same as GT). And there was maybe two others. 1.1 was a 4:11 ratio, but smaller rear differential
Front fenders are welded on, not bolted on, valves must be adjusted as it has solid lifter camshaft, if it has the 1.5 engine it is slow but the head can be used on the later low compression 1.9 to pep it up if you put the 1.9 valves in it. DO NOT attempt to adjust the valves with it running as you and every thing under the hood will get a hot oil shower, run it till it gets warm, cut it off and remove the valve cover and look down through the drain holes on the head and you can see the cam lobes, bump it on the starter until the lobe is pointed straight down and set it at .012. I always put a lock nut on top of the rocker nut to keep it from backing up and making the valve adjustment loosen up.
I think the sway bar was optional, at least in the early models, my ex -68 Olympia A coupe didn't have a front sway bar while my friends -69 Kadett B coupe had one. The transverse leaf front spring made it possible to delete the bar because it acted like one.
Not looking to go huge and want to stay with a stock body. I was figuring a 5” wheel, I saw 205/60/13 but recommended wheel width was 5.5” on the small side. 195 don’t seem to be an option. I want to do 155/80 on the front with the widest tire I can on back for an old school muscle “ big and lil’s“ look. I guess I will do the 185’s on the back. Thanks
This is a popular thread in another car forum that I frequent, so I thought I would try it out here, and see if it catches on.
In that forum, it is a "sticky" so it stays near the top of the thread list and has about 180 pages of replies. :cool:
Basically, just a few words or whatever you want...
Send like General Discussion ought to include other topics.... So FWIW
.. we're in Rangeley Maine to snowmobile!
We have rallied in this area before... In fact, I crashed my 1900 rally car not too far away in '92... a sad day.
News is spreading the Erhard Schnell passed away at age 93. He was a designed at Opel from 1952 to 1992 and was considered the "Father of the Opel GT".
I had the opportunity to visit him in 2012 and created an album of photos from those visits.
