Guest Spoon Posted October 8, 2006 Share Posted October 8, 2006 I've had this car a little more than 2 weeks now. It's a 1983 280ZX Turbo 2+2 automatic. It's only got 61k miles on it and in pretty good condition. I got it from the original owner and he seemed to keep really good care of it. The only thing i'm really concerned about is the slow acceleration. From a rolling start I can take off pretty good (for being an auto) but from a stop it seems a bit slow. What could be causing this? Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted October 8, 2006 Share Posted October 8, 2006 It needs two more cylinders. That's what I am adding to mine anyway. Quote Link to comment Share on other sites More sharing options...
Guest Spoon Posted October 8, 2006 Share Posted October 8, 2006 Why no 6 more? I have access to a BMW v12. I'm not really interested in putting in that much time and work at the moment. I might swap to a bigger engine at some point but with only 61k miles this one should still have a bit more life in it. Quote Link to comment Share on other sites More sharing options...
Mr.INSANE Posted October 8, 2006 Share Posted October 8, 2006 So its slow from a stop? Have a look at getting the tranny fluid changed that could help somewhat im not to informative on the auto's i hope someone will chime in Pop N Wood: What exactly was the point of that?

Guest Spoon Posted October 8, 2006 Share Posted October 8, 2006 I'll take it out for a run in a few minutes and try to time the 0-60 the best I can. Maybe I'm just expecting more out of it. Or maybe it just feels slow. Quote Link to comment Share on other sites More sharing options...
Guest Spoon Posted October 8, 2006 Share Posted October 8, 2006 So I just made a couple runs, stopwatch in hand(I know its not the most accurate method) the best time I got was 9.04. Quote Link to comment Share on other sites More sharing options...
mom'sZ Posted October 9, 2006 Share Posted October 9, 2006 Maybe the muffler / cat is plugged? Quote Link to comment Share on other sites More sharing options...
Sumo Posted October 9, 2006 Share Posted October 9, 2006 Check the distributor and see if it's loose and check your timing. Quote Link to comment Share on other sites More sharing options...
Guest Spoon Posted October 9, 2006 Share Posted October 9, 2006 muffler may play a part in it. I knocked on it and I could hear metal things bounce around in it. So, there is a good chance it might be a bit restricting. Quote Link to comment Share on other sites More sharing options...
Sumo Posted October 9, 2006 Share Posted October 9, 2006 If it's a clogged cat or muffler, disconnect just before the cat and see if there is a difference. good luck Quote Link to comment Share on other sites More sharing options...
wheelman Posted October 9, 2006 Share Posted October 9, 2006 Isn't a 9 second 0-60 about what those did in stock form when brand new. It is a 2+2 auto after all. Wheelman Quote Link to comment Share on other sites More sharing options...
Guest Spoon Posted October 9, 2006 Share Posted October 9, 2006 Yeah, I was doing a little research and found close to the same numbers. It still feels really slow on take off though. I'd be surprised if my Sonata(also an auto) didn't beat it off the line. Quote Link to comment Share on other sites More sharing options...
wheelman Posted October 10, 2006 Share Posted October 10, 2006 Well you are talking early 80s technology. Quote Link to comment Share on other sites More sharing options...

I'd be surprised if my Sonata(also an auto) didn't beat it off the line. Have you tried loading up the torque converter? I've beaten lots of cars off the line when doing this, the A/T let me build about 4lbs boost off the line and it moved nicely. It's a 5 speed now though.... more fun.

Guest Spoon Posted October 10, 2006 Share Posted October 10, 2006 I've tried that it helps a bit. How much of a pain was it to do the swap to the 5-speed? I'm thinking about doing the same thing. Quote Link to comment Share on other sites More sharing options...
roger.svoboda Posted October 15, 2006 Share Posted October 15, 2006 Make sure the kickdown switch and vacuum modulator are working. My 81zxt got smoked off the line by my son's Honda until I got up around 45 then said bye bye. Couldn't figure then one day at a light I pulled it down into first manually. wonder of wonders she took off pretty good then. Turns out someone disconnected the kickdown switch for unknown reasons so she was shifting into second at about 5 mph. when you trying to get off the line in second she pretty slow. Remember also straight six doesn't spool up like a v and takes awhile to come on boost. I went five speed route but you need to find donor car with all the right parts in place Quote Link to comment Share on other sites More sharing options...
