its a 2L DOHC rated at 208 HP .
it was build in the Opel Calibra and i think in the Vectra in the mid 90`s
F20 or F28 Gearboxes where used with them[This message has been edited by Fieromaniac (edited 03-05-2008).]

Here is a 2.0L Sunbird bellhousing, it is simmilar to a GM V6, but I dont know how well it will work, you would have to cut a hole out for starter clearance, and some of the bolts around there are in a different spot, plus the 2.0L OHC has some bellhousing bolts below the crank that go through the oil pan I think. It may bolt up on the front, but none of the bolts on the rear of the bellhousing will line up properly.
I believe this is the same block as the one pictured above[This message has been edited by befarrer (edited 03-04-2008).]

There isnt a 'fiero' adapter plate but Bates Engineering builds one for the ecotec that brings the pattern to the 'standard' pattern. Im using it hooked to the stock isuzi transmission. Now I must say the stock isuzi MT5 is sweet with the ecotec because for the first time I can do 0-60 in 1st and 2nd compared to 1st and shifting 2nd at like 55mph...

i dont mind .that engine looks interesting .is it all aluminum ? having the exhaust on that side of the head would make things easier in the fiero .with the belt drive cams and water pump it would be easy to work on .was it ever sent to north america ?

The 1.8/2.0 Sunbird engine was an iron block with a SOHC aluminum head. The newer Opel engines of the same family have DOHC heads that are supposed to fit. A simple head change was rumored to net about 60 hp.
The really interesting thing, to me, is that the rods and crank are cast iron put under 10 psi of boost at the max. That engine was a real beast in its day. 
The engine likes to eat cams and the head gaskets like to blow. A layered steel gasket will solve it, though. Not a whole lot you can do about the cam issue except perhaps open up the oil passages or experiment with different types of oil.

i guess ill go to the junkyard and take some pics of such an engine
would be great if the pattern matches without a adapterplate
btw. the available tuningstages for this engine are
phase 2 250 hp
phase 3 280-340 hp
phase 4 up to 450 hp
no NOS involved[This message has been edited by Fieromaniac (edited 03-05-2008).]

i relocated the charge pipe so that it now goes up and over the engine .the blow off valve tubing now follws the same path down to the new intake location under the trunk .i have removed about 6 feet of intake and charge pipe plumbing and 3 - 90* elbows .should help the flow a bit .i have mounted my 6:1 vortech FMU on the left hand side of the cylinder head (not connected yet , tomorrows job ).i now have a large space above the transaxle where i am going to properly mount the 2 ecotec fuse boxes and probably the ECU .and hide all the extra wiring .the engine runs very smooth now that all the vaccuum lines are connected and the new turbo position makes it impossibe for the oil to get past the seals and into the engine .i also relocated the brake booster check valve to the front of the car where it will be easier to change out .it looks a little melted on one side and although it seems to be working ok it will save crawling under the car to change it out .under my trunk is now quite crowded but everythings fits nicely .i am no longer using a muffler and it has a nice mellow sound that is not that loud .the turbo does double duty as a muffler now .i am going to try to do a youtube of the sound next week some time .i think most of you will be surprised at how nice this 4 cylinder sounds . pics :

got the FMU plumbed up and now i am adding the 100 psi holly inline booster fuel pump .i am doing this a bit different than usual .i dont want this pump to run except when the motor is under boost .so since my water meth system is boost activated , i am using a bypass line around the boost fuel pump with a check valve to prevent back flow when the boost pump kicks on .the feed from the water meth controller will activate a relay coil and the boost fuel pump will activate .i dont want to risk frying my water meth controller by running two pumps off of it so i will use a relay . i think this will be easier on the stock fuel pressure regulator and i dont need to listen to the noise of another electric pump running . pics:
all the plumbing is now hooked up tomorrow i will finish the wiring .
