Buying 1990 TII

[Canaduh]

Just want to say hi to everyone, i know i havn't posted in a long time, i have just been reading the forums, not alot of activity, and my posts seemed more annoying then helpful. Anyways.

Im going to take a look at a 1990 TII On Saturday, Guy says there is no rust, And 100 000kms (Canada not sure how many miles that is) Anyways, i just thought i'd ask around and see what i should be looking at. I have 2 pictures of it, ill post, The biggest concern is it doesn't have a turbo. He had a TD06SH-20G In there which is an upgraded turbo from stock i believe, and it was like a week old and he blew it, apparently he had the lines messed up. And he doesn't wat to invest in another turbo. So He's selling it, and for pretty cheap. 4500$ Canadian. When i go to look at it what should i be looking for and have any tips?
Thanks again, ill post pictures asap.
