  3. YOUR opinion on this ENGINE - CIH 1.6 N - head budget rebuild

    6F - Engine Rebuilding
    Hey everyone, So the engine (CIH 1.6N) on my ascona B decided to quit on me about a year ago. Since I knew "nothing" about mechanics I decided to seek for professional help. They said it was the head-gasket and that it would cost me north of 650€ to replace it. Being a college student, i'm...

  7. Building an Opel-powered drag race GT: AKA, project 'boom'.

    Member Projects
    Back in 1987, a close friend of mine decided to build an Opel for street use and drag racing use. He never finished it. Went gung-ho for a while then abandoned the project. He did manage to start on the engine side of things, doing a lot of stuff that I would have never contemplated for a street...

    General Discussions
    Now, I know it's really hard to get an opinion out of a car enthusiast, but I figured I'd try.:lmao: I want to get my 73 GT running as is, but I also want to build a nice but low budget extra engine to drop in next winter.

  9. Sportwagon from hell...header pics

This is not an end-all method by any means, it is simply a safe way to port a 1.9 head to improve performance rather than hurt it. This particular head is a 1971 1.9...

    Opel Engine Performance Modifications
    I don't know how I let myself get talked into these things... 7 weeks 'til Carlisle. I have to fabricate an entire turbo system for a CIH Opel, have parts coated and plated, tear-down and regasket an existing engine, install the engine, and dyno-tune it. We'll see if I even come close. So, the...
