Hey bud, I'm afraid you posted this at exactly the wrong time so I'll be naughty and nice.
If you want a serious answer, dont use 'txt speak', it makes you look like a 14 year old schoolboy.
This is a Nissan Gtir forum, you would probably get a much better and more informative answer on a dedicated 'Sunny' forum. Not many people here will have experience of fitting, say, a 2.0 litre engine in as they already have one
What model is the Sunny ? our model is an 'N14'. If yours isn't, their is little chance it would be a straight swap without some serious work, our engines are transverse with 4 wheel drive, so you'd probably be better looking at the 200SX engine and box ( 2WD ) or the Sunny Gti 2.0l model ( non-turbo ).
Sorry thats not much help...
