boostin280zx Posted February 9, 2006 Share Posted February 9, 2006 I am thinking about buying a r200 w/ 4.38 gears. I have a 82 280zx w/ '77 trans. I need to know if anyone has a z that is geared this low and is still a everyday driver. I have the 3.90 r200 right now and it seems like it is revved up high when im going down a highway around 90mph. I dont have a tach and i keep forgeting to hook up my laptop to my megasquirt to see what rpm it is at. Quote Link to comment Share on other sites More sharing options...
Projekt sixSTAR Posted February 9, 2006 Share Posted February 9, 2006 4.38 will rev up higher on the freeway, but it will be a rocket on the street. Quote Link to comment Share on other sites More sharing options...
iaconsultants Posted February 9, 2006 Share Posted February 9, 2006 If you have any power in your engine you will just spin tires in first gear and will probably have to take off from a stop sign in 2nd so that you don't spend all your money in tires. I on the other hand want to find gears on the other end of the spectrum. Kind of hoping to work out a gearing that is 273 or in that range.

boostin280zx Posted February 10, 2006 Author Share Posted February 10, 2006 I have a r200 w/ 3.545 gears ready to put in my car but don't know it is going to slow my car down any. I could use the longer first gear to build boost i guess, and i have plenty of power to turn it so ill probably just put that diff. in for now. Im going to the track tommorow so ill get my time slip and compare it to when i do the swap. Quote Link to comment Share on other sites More sharing options...
Guest Gus86ZX Posted February 18, 2006 Share Posted February 18, 2006 I have an r200 with 3.7 gears and open diff. I am buying a rebuilt LSD 3.9 for my car because my rear is whinning. I hope it will help light my tires. Quote Link to comment Share on other sites More sharing options...
