i am doing the swap here soon. I got all my swap parts for 400 including the t5, i think i got a good deal. I think most of the times they are around 500-700 or even more. but i found a car that i considered buying as a parts car, the motor was gone from in so i wanted of course the t5 parts and all the extra stuff. the car turned out to be pretty rough so i just bought all the t5 parts.
look hard, easiest and cheapest way is to buy a parts car.
but also, figure in the cost of a new clutch kit. i doubt you will use the old clutch...
back in the day i always looked at the almight "t5 swap" as something that would be hard and even harder to find the parts and time. But in reality its pretty east, i have done my reasearch and reading and it should go smoothly, except for maybe the pedals...
