Hey I have a 1987 rx7 n/a and the kid i bought it from said it was a blown engine but I can drive it fine it has a lsd on it and I've never had a lsd on my car I was wondering if my transmission or lsd if messed up because when I'm driving the car seems like its jolting but very weakly and when the lsd I believe kicks in or works the car bounces a lot i was just wondering if that is normal for the car or if the engine is blown o the transmission is messed up btw I do need to replace the clutch the kid before me had a passenger seat as a divers seat and he couldn't push the clutch in all the way because the back of the seat wouldn't stay all the way up and its grinds sometimes going in to reverse thanks

 

If you rewrite your post in something resembling English, you may get better answers...But based upon a wide guess on what you are asking, here is mine....

If the car is bucking slightly, it is probably just a misadjusted TPS. Also check the engine and transmission mounts. You won't "feel" the LSD "kick in".

Maybe the engine is blown? Perform a quick and dirty compression test: http://www.aaroncake.net/rx-7/blown.htm

 

thank you
sorry for the horrid spelling and grammar I didn't know how to explain what the feeling was
but are LSD's supposed to spin and stop and spin and stop while your turning?
