It's been done before. Not an easy bolt-on, but absolutely easy. You will need:

• C20XE (obviously) or a C20LET (been done as well)
• Getrag 240 OHC-version (Manta B 1.8 or an early Omega A with OHC) - now these are pretty rare these days (German ebay)
• Engine mounts (or make your own - not rocket science) and Oil pan with pickup tube from one of the above OHC engines (German ebay)
• Custom exhaust header or make your own, plus exhaust piping (headers for other C20XE-converted RWD Opels are available in Germany, might need to be modified for a GT)
• Enough energy to follow up with replacing everything in the cooling department. These engines need a closed pressurized system.
• Cost (to get all this in the US) ~ $5k to $10k, depending on how much you do yourself.
• Result: PRICELESS!!!

PS: I have a Kadett B, Kadett C, and Rekord E with C20XE/RWD configuration.

 

Conversion parts for a C20XE in to a GT:
Produktkategorien Motorumrüstung auf 16V-Motor (mit Katalysator) – Opel GT – | ATZ Opel-Ersatzteile The pricing is out of this world though. And a little correction to Dieters post, you don't find an OHC Getrag 240 in an Omega, but in a Rekord E. A 5-speed R25 with a cable actuated clutch from an Omega A is easier to find, but isn't as p & p as a G240 swap.

 

With the C20XE clutch and Getrag 240, does the shifter still line up? I assume the motor mount has to attach to the body at the stock location.

 

Yes, the shifter lines up. Well. of course, the shifter bracket has to be shortened, the exact same way as when you put a CIH-Getrag behind a CIH. Of course, you will use the same Opel GT motor mounts.

You need a 1.8L OHV RWD Getrag 240. I have a "kit" we are working on. I have found one of those and the C20XE.. 8045030249

 

One could also source a bellhousing that makes it possible to use T5 transmission:

I was wondering if BDD1 managed to install the c20xe and if so what was the process

 

I wonder about that too.

 

An odd post, especially for a new member, and came in via a Seattle VPN. This member is on the watch list, so DO NOT conduct any business with him until his identity has been verified.

 

For anyone curious. I have a used C20XE, with a rebuilt 1.8L OHV 240 Getrag coming over in the next crate that needs a home.

 

An easy 175 hp with only a swap to twin 45DCOEs. A ported head and a pair of hot cams and you have 200+ hp.
