Manual conversion

To get a manual conversion kit from the wreckers what specific parts will i need in relation to computer chages etc. for my 1991 series II 3.9l cfi 4 speed? Also if I traded in my 4 speed (good condition as far as i know) What sort of price should i aim for?

if your not changing from cfi to multipoint then the computer you have will be fine. the 3.9's have a seperate ecu for the 4 speed auto so the engine ecu wont experience any running problems from not having the auto there. If it were a 4.0 you would need to change the ecu.

If you get a box out of an EB everything will just plug straight in and work without any computer or wiring modifications. The 4spd computer is mounted on the pedal box so when u take it out just unplug the loom and take it out with the pedal box.

I just helped a mate convert his 90 series II 4spd wagon to 5spd and its goin strong.

There is also an Automatic Computer attached to the pedal box jammed way up in the dash board. Its the same size as the normal computer for the car but has Borg Warner written on it.

I think Brent meant that Borg Warner would have changed its name to BT-R by the time the 4 speed was released.

% Speed Conversion

If you want a complete description to convert the auto to a manual email me as this space is too short for a detailed description. I have successfully converted my car to a manual, and it is a really easy job. Buy a wreck though its far cheaper in parts. I bought an EA Fairmont GHIA for 400 bucks from work as a trade in and changed over all the interior too. The best thing to have at home is another car for spares. Basically, you need a clutch, fly wheel, trans wiring loom, brake and clutch pedal, gearbox and a piece of 5/8 rod welded under your dash for the clutch pedal. don't try to remove the metal bracket as half the car is dismantled by this time. This option is way easier. Good luck
