I'm confident you are asking about a 2.0 SOHC motor. Yes, the C20xe and C20let turbo cylinder heads will bolt up to an American 2.0 SOHC turbo or non turbo motor. The stronger rods and pistons can be bolted into the block. The crank can be swapped over. The thing is, the xe and let Euro motors use the same engine block from the same GM factory in Brazil as the American counterparts.
To swap the heads you need the full timing assembly, intake manifold and exhaust manifold. If you get the parts off of the turbo motor, this means a factory cast turbo manifold.
The biggest issue you will run into is the ignition system unless you are putting the parts onto a 2.0 mpfi.
If you decide to do a DOHC conversion, be sure to upgrade your internals. The DOHC heads will need DOHC pistons unless you have a 2.0 turbo motor where the pistons are dished. Also be sure to buy a Coscast version of the head, not a GM head. To diffentiate, the GM head has freeze plugs on the end of the head and Coscast does not. Coscast heads also have their logo stamped on the bottom between the three and four exhaust ports.

Part of the reasoning may be that you asked for parts for a 2.0 DOHC? The other part may be that they have no idea what a pontiac sunbird is. Try asking if a c20let head can be swapped over to a c20get (2.0 sohc turbo motor code in Europe, doesn't go by LT3 there.)
If they still say it doesn't fit, to hell with them. The swap has been done by myself and one other J owner in the states to my knowledge, possibly more.
Mr.Goodwrench-G.T. wrote:Correct. In some circles, the 1.9 DOHC Saturn motor is referred to as the "Precotec" because of it's role in the development of the current American 2.2L rendition of the Ecotec motors. It was no coincedence that the first appearance of the Ecotec motor in the US was in a Saturn ION...the replacement for the Saturn S-series that held the 1.9L motors for so long.sharkey wrote:the ecotec name has been used sine the mid 90s in europe. the first motor to bare the ecotec name was actualy a 2.0l dohc, from the same engine family as the 1.8/2.0l sohc motor in the sunbirds. our current l61/lsj has evolved from that 2.0l ecotec, but its roots do come from the old 1.8/2.0l.
Try again, more like a clean sheet design and it has more common traits from the Saturn's 1.9L and Quad-4 family. The only thing that the Opel design Ecotec has in common to the American design Ecotec is the fact it is a 4cyl and its name.

As I was typing that, I was picturing the car in my head, and I knew I was talking about the L-series. The L-series showed up with the Ecotec in 2000, then the ION followed in 2002.
