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...The 1.1L opel gts are pretty rare. I would keep the engine or you could get another gt with a 1.9L. I think only 3500 gt had the 1.1L in the us.
I already have spare parts from 3 opels in storage 70 thru 73 including 3rd members.and transmissions..driveshafts... Thanks for the information...crawl....Agree with the youngster. I would not consider such a swap on my 1.1.
However, your car; your choice.
Just off the top of my head, here are the things you need to make the swap. Others here are WAY more knowledgeable on Opels, and can weigh in.
Trans with bell housing, flywheel and clutch parts.
Rear axle with torque tube.
Rear Cross member.
Speedometer (guess you could use an adapter, but I was told Opel used different speedos for 1.1 and 1.9)
The only cost effective way would be to find a complete rusted out 1.9 car and use it as a donor vehicle.
Keep the 1.1L you can easily exceed the HP of a stock 1.9L with minor mods including head porting, a camshaft regrind and a tuned carb. The 1.1L handles better, has better throttle response, and is an overall smoother and more enjoyable engine.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...
I'll second thatPlease find a 1.9L GT instead and do not take apart one of the rarest opels in the US. There were less than 4000 1.1L GTs made and probably around 100 left if that.
1.1L GTs sell the same or 10% more if they are in good shape and not running like trash. The Germans will pay a crap ton for them too.Nonsense! Get rid of that 1.1. Nobody will give you a plug nickel for it. I've seen plenty of guys go to all the trouble of fixing up 1.1's and they were almost all put up for sale within a year of completion and they got peanuts for them. If they were any good they would have kept making them.
Swapping out the stuff mentioned is pretty much the drill for almost any GT restoration. Engine/tranny/rear axle are shot, front end needs a rebuild, all the brakes need to be tossed in the dumpster, etc.
Do your 1.9 swap and get the HP AND torque that you desire. Or go even bigger with a 2.0/2.2/2.4, since you already have a 1.9 car and already know what you get with that. Plus, I'm sure that it's a lot easier to find and hook up fuel injection on a 1.9 block engine than a 1.1.
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!I stand with Gordo...and Johnny Depp! Amber Heard and Kyler are Liars!
The benefit of a 1.1 is exclusivity. You want it because you want it. The benefit of the 1.9 is more power. If you go thru all that work, since you have to buy stuff to rebuild the motor anyway make sure you do some of the standard mods (32/36 Weber or single DCOE Weber, a not too big cam, flat top pistons, decent 2" exhaust, that really won't cost much more to make it a bit more enjoyable. But keep all the 1.1 parts wrapped and safe. As Amber says, there are very few 1.1 GT's left and someday Johnny might write a big check for it.Hello all...I Own a 69 gt with A 1.1 engine.
