Flood isn't a total sewer, and even if it was, it just means ALG needs to do a better job.

If people say the intake bolts up, I'd believe them. Watch out for brackets though, usually a lot of changes there for small things as years go by, I would imagine this is especially true with turbo.
They certainly do, the only problem is that if you bolt the MPFI manifold to the 1.6 liter head, you can actually see the edges of the intake ports on the head, which isn't a good thing.
The other thing is, the engine does not have a turbo. Why people have been mentioning a turbo I have no idea. lol
@Noobl3t, I know you are poking a bit of fun there, but here is some info anyway.
Apparently the 1990 Pulsar Q (5 door hatch) came in two types, the Australian version, which had a motor made in the GM factory (and also installed in the Holden Astra) or the Japanese(?) version which had the Japanese built motor, which is slightly more powerful then the Australian version.
As to 'why flood?'..... more people check flood, just on account.

Buy the intake gaskets for both engines and see what you can make work. I ended up using some high-temp epoxy (JB Weld) to correct some small differences. You can see here, the edge of the 4.9L gasket did not correctly align with the left edge of the coolant channel on the 4.5L intake.
So I turned it sideways, put some painters tape on the edge, filled it with epoxy, then shaped it to fit.
Coin's comment about transmissions is worth investigating too. The biggest long-term problem I had with my swap is that the torque increased about 50% over the original setup, and the hydraulic transmission did not respond well to changes in the fluid pressure curve. Long term, I will have to switch to electronic transmission controller.

The thing is, I'm not the one doing the work, my Father is and he has pretty much got the motor sorted.
Just about the only thing I've done on this project is a little research and helping take the motor out and it's a pretty good guess that I'm going to help put it back in again.
If I made it sound more complicated than it actually is, well that's mostly because I thought it WAS going to be more complicated than it has actually turned out to be.
Short version of what has happened so far;
1. Motor blew up for some reason.
2. We *tried* to get a second hand 1.8 liter motor of the same type, couldn't get one.
3. Got a 1.6 liter motor, same as 1.8 mechanically, except for bore size.
4. Fitted 1.8 heads to 1.6 block, along with MPFI system.
5. Mated completed modified 1.6 motor to transmission (automatic)
Annnd that is where we are now.
I expect Dad and I will install the motor in the next few days with a bit of luck.
My sister is flying in for a few days, so it might not happen while she is here.

Well, today was the day.
After a bit of messing around with the engine and hooking everything up, the Father attached a battery and minus the spark plugs, cranked the motor over.
Everything happened as it should, complete with a healthy petrol smell coming out of the spark plug holes and very healthy looking big fat spark from the coil jumping across to the block.
No crunchy/breaking sounds to be heard.
With a little work putting in the spark plugs (the plug on number 4 did NOT want to go in), the motor was started again, this time for real.
It started and idled first time!
I'm a little amazed.
Seems to rev up all right too, the Father gave it a bit of gas and it sounds good.
The plan right now is to start it up and let it idle a bit in the next day or so, to let the motor scavenge any lumps and garbage that might be in the engine, then do a oil change and do it all over again.
