Using the exhaust manifold intended for the 2004 GRM Challenge Manta, I threw this sucker together for a Kadett wagon turbo installation. Since the head is a 2.2 head, I made an intake manifold from scratch with shorter runners and a bigger plenum which would still clear the exhaust manifold. Hope to have it done for Saturday. Nothing fancy, no plating or polishing (in fact the exhaust manifold has been outside since last year). Figured it might give some of you some ideas!

Hey BoB?

Hey Bob Can you super charge the 1.9 from the 74 sportwagon as well as take it from 1.9liters to 2.2
liters Or is turbo charging the easier way? and is there a company that manufactures the conversion kit and possibly a header for the same engine? Also would you happen to know the wheel bolt pattern size for the 74 Opels??

Sure, no reason why not. Lots of room compared to a GT. But you need to start with a fresh engine, a tired old engine will break the ring lands off the pistons in short order.

as well as take it from 1.9liters to 2.2

You'd need a 2.2 crank/pistons and rebore to 95 mm to get this displacement.

liters and is there a company that manufactures the conversion kit

For the 2.2 engine? Nope. But Opel GT Source sells 2.2 shortblocks and longblocks complete.

and possibly a header for the same engine?

I don't know of anyone making new headers for the Manta/Ascona/wagon. Once in a while something pops up on Ebay, but most of those are junk anyway.

Also would you happen to know the bolt pattern size for the 74 Opels??

For the wheels? It's 4 x 100 mm.

Or is turbo charging the easier way?

Probably a bit more fabrication for turbocharging, but more power potential too. Depends on your abilities. You won't find a kit for either a turbo or a supercharger for an old Opel. And forget going carbureted, EFI is the only way to go for reliability and power with forced induction. So in either case there's going to be a substantial dollar investment unless you are good at scouring junkyards and fabricating.

HTH,
Bob

I have to admit, the search feature is a nice thing to have. When I was looking for wiring harness' the other day, I found the name of the company I couldn't quite recall using the search engine here, rather than posting a question that's already been answered before. Found the results in seconds! Thanks again Gary....

SUPERB . . . as usual!

Superb work as usual, Bob!! KUDOS!! I especially like the combined intake/exhaust approach! Gets around all the mounting thickness problems in one fell swoop!

I realize it's tough to see from the photos, but the manifolds are separate pieces and are retained in the normal fashion.

The Kadett turbo setup is finished with time to spare. Well, not exactly finished, it needs a flange for a TB welded in place, and injector bungs added to it too. But, the car owner will be doing those things himself to fit the parts he already has. Should make for a pretty nasty Kadett wagon I think? The best part is, the total material investment so far it about $100. Add a turbo, an intercooler, injectors and pressure regulator, fuel pump and lines, and a Megasquirt EFI system, and 250 hp is easy.

That's some Frankenstein you've created there, Bob!

Bob Looks Great as usual!!! Must be nice too have the know how and machine shop in your garage!!!

Dr. Frankenstein was German, wasn't he??? Must be something here...hmmm.

Would love to see what you, Otto and some of the others here could build if you lived close together!


Regards,
Rick

Thanks Rick.

Stephen (AKA Oldopelguy) has come and gone already and picked up his Kadett manifolds and some other misc. stuff on his way to Maine. Let me tell you, this is going to be one VERY interesting car he's putting together. Imagine a Kadett wagon with fender flares, lowered suspension, and turbo/EFI 2.2 litre engine cruising the highways of South Dakota looking for helpless victims....

Stephen lives only a few hundred miles from me and has time to travel and sightsee, thus, should I be on my way home from work and be lined up at the traffic light with an Opel, when it turns green I'd better totally floor my S10 daily driver (412 ci, 700 trans, 4.10 gear) to prevent being embarrassed!!
