I'm converting my dx to si, and I have already finished with the minor problem with finding out what distribor to use. Do I need the same year Si dis. or a new one or what ?? Is there anyway to make my stock one work? Last but not least where can I buy a replacement Trottle posistion Senor, without buy a whole new trottlebody ( honda wants $450.00 for a new trottle body)? Thanx.. My car went 15.1 with a completly stock DX motor with 150,000+ miles on it... Ole, yea and a little zex too...75+92+167hp...

 

Do a search. There are so many threads on this! (top right corner of the screen).
Welcome to Honda-Tech.

 

you need the 7 plug si dizzy. a 7 plug hf one will work. carefull tho, parts store try to sell the 5 plug dx dizzy as an hf one. there is no realistic way to make a dx dizzy work. your missing the crank angle sensor which is responsible to fuel injection. thats why the si has 2 extra wires. blue/green and blue/yellow

 

if you have no choice, dont hook up c1 and c2 to blue/yellow and blue/green ( i think think those are the colors) car will run for **** and rev only up to 3K rpm but it wont run lean so you can drive it somwhere to pick up an si dizzy
