I'm pretty sure Keith was trying to be humorous. Even if you aren't interested in the Depp - Heard situation, it's everywhere right now. I think the Kardashians might be jealous of all the attention they are getting.If this is the direction the forum is going...I'd rather have the political 'discussions'....what's next? Kardashian updates? To maintain civility on the forum we must act our age and pretend there is nothing new to report since China repossessed Hong Kong!
If you want the get-up and go, I'd use the 1.9 from the 70, more hp.Hello my name is Jerry... The 1.1 has no get up and go.i already have a 1.9 and want more power and want to keep the fuel economy...
I already have spare parts from 3 opels in storage 70 thru 73 including 3rd members.and transmissions..driveshafts... Thanks for the information...crawl....
The radiator is not the same. The 1.1L radiator is itty bitty. The engine crossmember is different and the stock 4.11 1.1L rear end is really too wimpy for 1.9L torque. It wouldn’t be a hard swap but you need a donor car.If you want the get-up and go, I'd use the 1.9 from the 70, more hp.
I had a 69 w/1.1 that was shot and the conversion to the 1.9 was a piece of cake, forty years ago. No rear change and the radiator was the same, I think? Here is a pic and the kid in the pic is now 47.
I’ve been at this nearly a decade now and in that time I’ve brought more opels back on the road than anyone but Keith has in the same amount of time. I have also researched and studied these cars more than 98% of people on here probably.All due respect to Kyler, who is a great fan of Opels and an asset to the community, but he's also a young guy with limited Opel experience and hasn't seen as many Opels as some of us. AND he also recently got himself a 1.1 Kadett, so, obviously, he's a cheerleader of them.....for now. Some of us have been driving Opels longer than he's been alive and been on this website since it began and seen a number of attempts at 1.1 fix-ups and their sale relatively quickly thereafter. Keith probably has the best sense of the pulse of the buying public of any of us, since he fixes up and/or sells Opels in all sorts of degrees of oem and heavily modified. And yes, most 4sp equipped GT's have pretty worn rear axles(ones that had autos are almost never worn out). 2 of the 5 GT's I've had and driven so far(a new undriven one in the pipeline) had completely screwed 4sps(The other 3 with autos worked like brand new and refuse to break). And everyone who gets a used GT that's been sitting for a long time probably needs to rebuild the engine, whether it's a 1.1 or a 1.9, and there's a heck of a lot more performance enhancing goodies available for the 1.9's than there are for 1.1's.
The best reason to fix up a 1.1 is for the challenge of it, but it's low power is totally inappropriate for a rocket ship-shaped car like a GT.
FWIW after rereading the whole post and all the comments. The real answer wasn't really a 100% addressed.Hello all...I Own a 69 gt with A 1.1 engine. I want to install a 1.9 engine.. how many changes are needed to make this happen? Thanks...crawlinghamd...
Front suspension is fine. The only thing different is the brake piston diameters. The leaf spring will still work with the added engine weight.FWIW after rereading the whole post and all the comments. The real answer wasn't really a 100% addressed.
In short the 1.1L is about 100 lbs lighter, and due to the lower horsepower ( which is the same horsepower FWIW as a 71-73 low compression motor ) everything was lighter and smaller. Overall the 1.1L is about 300-400 lbs lighter if memory serves.
By Everything I mean everything. Both axles, the entire brake system, the entire drivetrain from front to rear.
Wiring I think is even a touch different. But doubt it would matter much if it were.
In short, the body was the same interior was the same (Although the speedometer is different as well. ), thats about it. I do believe the mounts for suspension, brakes, and rear are the same as the 1.9L.
So "technically" it would easy. Unbolt the body from the drive train and replace everything. If you were planning on a rotisserie restoration, you could just put the body on the rotisserie and then rebuild everything off your parts cars and put it back together as a 1.9L. But be sure to build it as a 2.0 or 1.9L High Compression motor. Otherwise your just converting it to an even slower heavier car. As the HP difference between a 69 1.1L and a 72 1.9L Low compression motor is like +/-10 HP. But the 1.1L has a much better HP to wgt ratio.
