A few questions from a n00b. Options

Hello, I'm a newbie. I recently (like 2-3 months ago) bought a 95 Celica ST. Its damn enjoyable to drive but its got fairly high kilometers on it. Yesterday while switching spots in my driveway I was told that it was blowing a bit of white smoke not too much, but enough for me to notice when I turned my head and looked.

My first question: Is this a normal thing to have happen with a high km 7A-FE while starting cold?

The engine and transmission have just under 280,000km.

My next question: How many kms does the average 7A-FE run?

Now when I bought this thing, I was half expecting to replace the drivetrain within a year partly because of how much milage was on it and partly because I like like to take **** apart and modify it.

So my last question is: What fun swaps can I do on a student budget?

As for that one, I don't really know what I want. I like the idea of NA because of quick response and usable power, but I'm kind of addicted to the sound of a turbo. The V6 swap would also be a cool idea but only if I can retain my manual transmission.

Its also pretty hard for me to locate parts considering I have absolutely no idea where to start and where I should source my parts since I no nobody who's actually modified their car for speed. Everything on the eastern side of north America seems to be about show and not go. That being said I know nobody who's swapped/built an engine, just kids with lambo doors and hydraulics.

So if anyone knows where to get parts in southern Ontario, that knowledge would be greatly appreciated aswell.

Took the plugs off, they look pretty new (since the electrode looks pretty square still) so the previous owner must have changed them before he sold me the car, however they are not metal colored, they are covered in something and look white-ish. Air filter looks pretty clean and new, no issues there.

However once I did all this, I took it for a spin, backed up from my driveway onto the road and a big white plume of smoke came out. This was the only time it smoked during the entire ride.

I still have no clue what's wrong with it but I've never seen a car put out that much smoke after starting and its only done it a few times. I'll just try to ignore it for now and save up for a swap anyways.
