So you want to transplant that into the XR? If so I dont know if its the best idea Ive ever heard. They are no GTHO, but seems a bit of a waste.
Id sell it and then get something else to do the transplant in.
But, as for price, maybe $1.5k for the whole lot (eng=~$500, trans=~$500, zorts=~$300,
ECU and Tailshaft ~$250).
Just a very rough estimate. Some parts might be worth more to others. Its like ebay etc, one thing will sell for say $100, and then the next day, the exact same thing will go for $200.
Just got to find the right people.
