cygnusx1 Posted August 8, 2003 Share Posted August 8, 2003 I just finished installing an 83 Turbo motor into my 76Z. The entire 83 ECCS system is being used. I just got the motor fired up and the timing is about 18 degrees AFTER TDC (off the scale) at idle! I had the oil pump and the dist out. Did I put them in on the wrong gear tooth? Where should the idle timing be and how do I get it there? Photos and a video-->http://www.hvmp.com/dc Thanks, Dave C. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted August 8, 2003 Share Posted August 8, 2003 20* BTDC. The TPS needs to be closed. If you can't get there, you have to drop the pump and move it back a tooth (or two, or three). Err, supposedly the '83 is weird, and is set to 24* BTDC Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted August 9, 2003 Author Share Posted August 9, 2003 Thanks, I was afraid that I had to drop the pump again....oh well. I appreciate the info. I need to go about 38 degrees advanced from where it is now. That should help my throttle response. Dave C. Nice Dyno Numbers by the way SleeperZ!

Mudge Posted August 9, 2003 Share Posted August 9, 2003 I read that it was 20ºBTDC even after the 83 cars(?) Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted August 9, 2003 Share Posted August 9, 2003 Yeah, I think all the Z31s were timed to 20 also. Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted August 10, 2003 Author Share Posted August 10, 2003 Well after 3 tries by dropping the oil pump and changing the gear tooth mesh, I got a tooth that gives me exactly 20 BTDC at idle. What a difference! Much better. Thanks. Dave C. Quote Link to comment Share on other sites More sharing options...
