Opel Manta 2.0 OHC Automat from Finland

[pecu_83]

Hi there all you opel fans!

I just stumbled here to this forum and thought I´d register. There are a lot of nice projects going on here, so I decided to put mine on display too.

I bought the car in the summer of 2005, when someone wanted to buy a gearstick to his Manta from me, I ended up buing the Manta from him. At first I just cruised around with it and tuned up the engine and made some minor modifications like moving the gas tank. Then a mysterious problem came with the carburators and I just couldn´t solve it (later i solved it, someone had drilled the idle nozzles i put in VERY big). So I ended up putting a L-Jetronic in it. It also had a mysterious problem (it turned out to be in the wiring) so I decided to do something else. At the same time my friend got in to an
accident when trying to avoid hitting a moose on the road, he ended up wrecking his Omega. Then we had a masterplan to put the engine and gearbox from his Omega to my Manta.

This is what the car looked like when I bought it:

First I took it a part, there were lots of corrosion to be repaired.

Then I made some reinsforcements to the body and chassis.

After that I started modifying the engine parts to fit Manta. The oil pan is modified from Kadett E.

I cut away a lot of the floor to make room for the new gearbox.

Then I made new engine and gearbox mounts.

After that I checked the engine. It was in good condition. I replaced the cylinder head and the camshaft from a 1.8 GSI Kadett E. And moved the distributor to the front.

Then I modified the handbrake lever and made a place for the gearshifter.

When those were done, it was time to build the propeller shaft. Since Omegas propeller shaft doesn´t have a "slide" (dont know what that is called) in it and the mounting to the gearbox is different (and lenght of course) I had to build the propeller shaft by combining Omegas and Mantas shafts.

Finally it was time to put some new sheet metal to the body.

The axles were cleaned and painted also.

Then it was time to begin working on the paint job.

http://www.teammadmax.com/gallery/d/...mantaa+003.jpg

First I painted the front with a different shade of purple.

Then I made som flames.

Then I painted the rest of the car with a different shade.

http://www.teammadmax.com/gallery/d/...130806+030.jpg

And made some highlights.

After the paint job was done, I re-mounted the engine and gearbox, made a new exhaust, re-mounted the interior, put in bigger brakes and my friend re-wired the whole car.

First, welcome to the forums.
You have a very interesting Manta A project.

[blauwmarc]

Nice to know there's a cool manta A in Finland. You did good work. What's the difference between the old engine and this OHC you build in? (i mean, its performance)

Holy smoke! What kind of a huge gear box is that?

The old engine had ~170 hp and the new one has 135 hp
