I own a 86.5 with that I purchased last year the previous owner had installed and decided to sell the car because he was down sizing his house to a condo (retired guy). Qualifying this with....I've not driven it much as the major service needs to be done. I'm just starting that process, so what I can tell you:
It works. I've not "throttled" the car because of the TB issue (never been changed that I know of...car only has 38K on the ODO). It's snappier than the auto and functions fine. The R light comes on in Reverse, and the only negative I can tell you is there is road and wind noise around the shifter because there is simply a piece of plastic covering the old AUTO hole that the 6 speed replaced. I assume I can fix that with some DYANAMAT or something similar. Here is the link to my car Carl posted when he did the swap
I will have the car running soon...I hope. I have all the parts here or on order for the TB and WP and will be able to drive it soon. let me know if you have questions.
