1971 Turbo Gremlin

["Clarence Milstead" <cmilstead@xxxxxxxxxxxxxxxxx>]

Ten years ago I added a Garrett turbo to my 1971 Gremlin. It was featured in
the Jan/Feb  1996 issue of Dick Datson's 21st Century Turbo newsletter and
also on the Turboforce web site. I still have it and it's running fine but I
have a few questions I'd like your opinion on. I have the aluminum case
air-cooled BW transmission, model M-43. It's been a good transmission and I
had it rebuilt at 250K miles. In normal driving it shifts OK but won't shift
out of low gear unless I lift for a second during hard acceleration. I think
it's probably the governor, what do you think? I have the TSM and have read
the procedure for checking the governor, can I do it with the car up on
jackstands or will I have a problem? I have the 7 9/16 axle with the 2.73
ratio. I'd like to go to a lower (higher) ratio, maybe 3.15 or 3.31 for
better performance. What's the best way to do this, try to find an axle in a
salvage yard or buy new gears for my differential? I'm an engine man not an
axle man, can I do the work myself? I've read the procedure but never done
it. Mileage isn't a problem, I drive the car in town only. A couple of final
questions, if the BW breaks what is the best and easiest replacement? And,
how much horsepower is my turbo 258 making? I have the Garrett turbo, a Comp
Cam 260, Mallory ignition, Holley 500cfm carb, 2 1/4" exhaust and don't turn
it much over 4500 RPM. Thanks for your advice.
