Guest loveonthebeach Posted February 8, 2003 Share Posted February 8, 2003 Hey guys. Alright, i don't have enough money to buy the SDS with the ignition control. For a 280zxt motor, will the SDS EM-4D work if i'm upgrading to 440cc injectors, t3/to4e hybrid, and only plan on running 15 psi max? Is is better to wait until i can afford $985 to get the EM-4E ? I was debating about just getting the JWT chip, but everybody swears by the SDS systems. Thanks for the input. Quote Link to comment Share on other sites More sharing options...
fl327 Posted February 8, 2003 Share Posted February 8, 2003 yes it will, you gotta use the NA distributor with either vacum advance locked out, or a msd boost retard box or something to keep it from advancingyou into the world of ping.

Guest loveonthebeach Posted February 9, 2003 Share Posted February 9, 2003 LEN168, you seem to know a lot about this stuff, maybe you should just build my car for me So if i use the SDS EM-D4 with the msd boost retarding box, it will be fine? What effect does the boost retarding box have on horsepower, if any? Quote Link to comment Share on other sites More sharing options...
