Hello everyone just thought I would make a voice. I anm currently getting started on a project that I know will end up taking a long time to complete, but I'm not typically the person to just give up on a project, so here are the plans...... Irecently inherited a 1968 kadett rallye (silver) from my father who has owned this car since 70' something, and also have a 1990 Eagle Talon turbo all wheel drive. basically I will be combining the opel w/the talon engine. I will need to find a trans. that will bolt to the once transverse mounted engine but that should be my most difficult task...I THINK. anyhow I will post pics asap of the project car. thanks to everyone for the wonderful website and loads of info! :)

I believe that one of our members who has a GT with a 2.8 Ford V6 was planning on a Talon engine swap (well, it was the clone from Hyundai), but he found that there was no such transmission available to turn it into a rear-wheel drive setup. Have a look around the "Engine Swap Forum" and you should find the thread.

4g63rallye
Please dont chop up that 68 rallye. If you want to make a hot rod then do it with something like a kadett coup or a GT. But the rallyes are not that plentiful to begin with. Better yet just sell me your 68 rallye kadett!!

here are a couple of pics with the wheels that will be placed on the car along with lots of other parts from the talon. The car itself has a bit of surface rust but there aren't any holes from it, being an original arizona car. So please give me your opinions, what do ya think?

I found the thread about the Talon engine swap, and it can be found at:

The fellow who was planning it is a fellow Canadian, Dan, from Regina, and his GT had a Ford 2.8 V-6 that he wanted to swap out for the 4g63 Mitsubishi engine. You might want to drop him a line to see what happened to cause him to quit, as he had a complete engine, and was ready to go, pending the rear-wheel drive tranny

More Room

The "other" Talon/Hyundi engine swap was into a GT - you will have a lot more room under the hood in a Kadett. With a bit of Hot Rod engineering a suitable gearbox can be adapted to your motor - a T-5 BorgWarner or even a RWD Toyota Celica box would be good candidates. Both are five-speeds too.
T-5s have been used in Opels along with the S-10 clutch - a search should turn up some references for you.

Yeah, that was me attempting the 4G63 into my GT. I ran into some serious issues with the project and the idea was scrapped. The main problem was finding a RWD transmission that would work. The only RWD tranny that will bolt straight on to the 4G63 is the 5-speed found in a few rare 2-litre Dodge D50 pickup trucks. And not only that, but they only fit wide-block 4G63's, most that you find in DSM's will be narrow-block. Then not to mention, you have to go and find all these parts in a junkyard yourself, which is impossible when you're like me and live in Canada and all the wrecked cars are in the States. What are you going to do, ask people to go to junkyards for you, remove a transmission and ship it to you? I don't know anyone that would know the first thing about Dodge D50 transmissions or even what a D50 looks like. So then there's the option that Eric Plebani patented, and that's taking this one tranny (I forget the name of it now) and dumping all the internals and then swapping the Conquest / Starion transmission internals into the housing. But guess who's the only one that knows how to do it? Eric Plebani himself. And good luck getting a hold of the guy. So then there's option 3, which is use the W58 5-speed from the Supra - a favorite among old European car restorers. Some guy in Orlando came up with a custom bellhousing to mount a W58 to the 4G63, but guess what! No one can get a hold of him anymore. So in the end you're left with option 4, which is to go to Dave Buschur and buy his Powerglide kit for around the area of $4,000 usd. And then you're left with a 200 pound transmission with only two speeds, the only thing it's good for would be drag racing.

Oh, and that's just the transmission problem. You run into a new problem if you try putting the 4G63 into the Opel engine bay. The 4G63 is a very tall engine and the valve cover will hit the hood when it's mounted. Not to mention the width of the 16 Valve head puts the exhaust manifold and turbo right where your feet and pedals need to be, so some serious cutting and fabrication would be needed there, and plus the intake manifold will knock against the heater core area in the engine bay, so you would have to remove your heater core and cut that section of sheet metal out. But you're doing it in a Kadett, so it might be slightly different for you, I don't know.

I have a used AWD 5 speed transmission from a 1993 Eagle Talon. You might be able to use it in your project. You might be able to use the rear output shaft for your rear wheel drive and block off the front output shaft.
No, you can't. The AWD transmission has a viscous coupling in it. If you have no resistance on the front driveshaft (left open) and only the rear wheels connected to the rear driveshaft output, the VC will try desperately to transfer power to the rear shaft only but will create a ton of heat and completely fail, wrecking your transmission. Same effect as if you pulled one axle out of your rear differential and tried to drive. All of the engine's power would naturally go to the open side and it would just spin and you wouldn't move.

Anyways, I purchased a totalled 1987 Nissan 200SX Turbo in January and have stripped everything out of it. Engine, transmission, full body wiring harness, clutch cylinder, hydraulics, etc. and it's all in the process of being mounted into the GT. The 1.8 litre CA18ET is a perfect fit in the Opel's engine bay with no clearance issues (mostly thanks to the SOHC head). The transmission is on the long side and places the engine slightly forward in the engine bay, but nothing problematic. The CA18ET produces 120hp stock, which is with 4 pounds of boost non-intercooled. I have a 60-series T3 which will be fitted to it, as well as an intercooler from an '89 Starion, and I expect around 200hp @ 14psi. The CA18ET is also extremely light, much more so than the 4G63, so 200hp in a very light Opel should be a blast to drive.

I'll keep everyone updated as things progress.

Actually we also have a 1969 4-door sedan, and three wagons that are in much better shape than the Kadett, but I like the Kadett body the best so we have several engines and cars that we would probably be willing to part with. :)
