DatsunLSX Posted April 16, 2012 Share Posted April 16, 2012 Ok I have had this 77 Datsun for about a year now and starting to tear into it. I was going to go a ls motor but went the carb setup instead. I recently bought a 350 motor and turbo 400 transmission that came out of a farm truck. My main question now is will the turbo 350 transmission mount work with the turbo 400 or will this be a custom bracket that I will need to be made?

Mike kZ Posted April 17, 2012 Share Posted April 17, 2012 It should work. Are you sure you wnat to go with a 3 speed auto? Check this thread: http://forums.hybridz.org/index.php/topic/106131-turbo-350-trans/ Quote Link to comment Share on other sites More sharing options...
Michael Posted April 18, 2012 Share Posted April 18, 2012 If I'm not mistaken, the mounting location on the tailshaft is different between the TH350 and TH400. That however should be a relatively minor issue. The larger issue, as MikeKZ pointed out, is the ratios in the TH350/400. Quote Link to comment Share on other sites More sharing options...
DatsunLSX Posted April 22, 2012 Author Share Posted April 22, 2012 (edited) This is where I get lost at, I don't do well with the drive line ratio's. What would be a recommendation on this. If I was to use this Turbo 400 transmission how would it act as in driving on the street. This is going to be just a fun vehicle nothing freeway speeds besides a couple times but most 45-50 mph zones. Edit: The other question I have is I have read a lot of people that have turbo 400 trans have 3.55 rear gears but if my research is right doesn't the R200 diff(manual) already have 3.54 rear gears?

The Infidel Posted April 22, 2012 Share Posted April 22, 2012 (edited) I run a th400 with a 2800-3000 stall with 3.54 rear gears and a 25inch tall tire. Its roughly around 3200rpm at 65mph on the freeway. The droning from the exhaust is annoying more than anything.
