Timing for B303??????

depends a lot more on your combo and set up. When i had my b cam, I ran 16 degrees of timing in the summer with 34 degree's fuel pressure. Never ran lean on the dyno or the track., but I had 24lb injectors and a 255 fuel pump. Any mods, heads, aluminum or iron.. more info.. .... 10 - 12 degrees should get ya bumpin for now though.

Aluminum heads like more ignition timing. Add more till it runs slower then back off 2*

I used to have a 302 in my hatch with the E303 I ran 14* and It ran awesome. I also had 1.7 rockers 65mm throttle body, 70mm maf and ported heads. hope this helps

Hmmm, I am not sure what your talking about with the vaccum stuff. I can go out in the garage and look. As far as i have ever known, with our fuel injection cars you dont have to do anything but pull out the spout connector attatched to the distirbutor, and adjust the timing. I marked my balancer with white out on 10, 14, 16, 18 degree's so it was easier to see with the timing light. .. thats all i know of.. Someone else care to chime in?? If you dont have an adjustable fuel regulator I probably would stick around 14 degrees. Ah ha.. i just re-red teh original replies BT15 did his on a carb'd car... you dont need to worry about the vaccumm stuff.. hehe.. If you have any more ??s just post up.

I run 14* and 93 octane. As long as your not getting pinging you should be fine. I think 14 is perfect.

I run mine the same way, seems to work nice.
