Edmonton 240 Engines and Parts?

[Sparkfist]

Ok so I live in Edmonton and currently have a 91 240sx 5 speed stock with some problems.

Im looking to either fix up the current motor and get my 5th gear fixed in the trans. or to swap it out and get it back on the road. It will be a year round car so im unsure of a turbo. I will do all the work myself with a mechanic friend so labor isnt much of a problem but im having a real hard time finding local parts or info on where to get my hands on a engine.

Any guesses on the price to fix up a stock 240? as far as i know nothing is wrong with the engine just the trans lost 5th ( it just seems to be blocked i cant get it to move forward or even grind anything but 1-4 and R work fine ).

I found a few places on here that say they sell the sr20's and such but no reviews from members or anyone saying what was missing/included with the purchase. Im assumeing $2500 for a sr20 is about the going rate?

Any and all info would be great!
Thanks in advance
